Health & Co: What is health, and how does health promotion work? We will try to answer these questions on the page "Health & Co". For more information please click here.

    Learning modules: In these chapters, we will provide background information on the offered subjects: e. g. recommended internet links and literature, didactic proposals for classroom and project activities.
For more information please click on the learning modules: acne, sunlight, dermatitis and skin health and STD. Also, you have access to Background information on the subject skin.

Health & Co

There are very different notions about health. But they have usually one thing in common: health concerns everyone.

If you are interested to read more about health and health promotion, please read on in the following chapter.

  Health: Here we will get to the bottom of the question: "What is health?" Please find more information here.
     
  Health promotion: The main question is: "How can we promote health?" Please find the answers here.
     

  Salutogenesis: In the concept of health promotion, the main focus is not necessarily on the risk factors that make people sick, but on the resources of the individual person to stay healthy. Please find more about the salutogenetic model here.
     
  HAPA model: The HAPA model provides important ideas on how to realize health promotion in a learning environment. The HAPA model is described here.
     
  Literature: Please find further literature recommendations here.

Health

What do people often write on birthday cards? „Happy birthday, a successful new year, and stay healthy above all!” Health seems to play an important role for a good or even happy life. A famous German Philosopher – Schopenhauer – said once: “Health is not everything, but without health everything is nothing". These are examples for the importance health has for many people.

If you try to describe health in a few words, you will discover that this is difficult. Maybe one of the reasons why a general definition is difficult is that everyone has very personal perceptions of health. Personal experiences and individual character traits play an important role in everybody’s definition of health. Please find some notions of health in the overview below. Some definitions focus on the physical functioning of the “human machine”, others define health as the absence of illness. Others define it more globally and focus on human well-being under varying experiences and viewpoints (e. g. our own body, emotions, relationship to other people).

The differing perceptions of health can be related to differing behaviour patterns. People who feel that they have no influence on their health, because it depends on coincidence or higher powers, will probably not fight to improve and maintain their health. But people who feel that their health is at their own responsibility will probably tend to avoid damaging behaviour and will try to support their health actively.

The World Health Organization (WHO) created the best-known definition of health: “Health is a situation of complete physical, social and mental well-being and not as the absence of illness or ailment.” (World Health Organization 1946)

Important in this definition is the holistic claim. In those years, it was not self-evident to put the mental and also the social well-being on one level with the physical well-being as a condition for health.

Health promotion

What does health promotion mean? The World Health Organization provided a well-known definition for that as well:

 

""Health promotion is the process of enabling people to increase control over, and to improve, their health." (WHO 1986). 

 

This guiding principle has been applied in our project about skin diseases and sexually transmitted diseases. Thus the pupils will be able to learn and to make experiences how to improve their health on some areas of health at their choice.

In the so-called Ottawa Charter for Health Promotion (1986), the WHO suggests three basic action strategies and five key action areas for Health Promotion.

  The three action strategies of Health Promotion are: to advocate, to enable and to mediate. These three action strategies are described in further detail on the WHO website. Please access the site here.
     
  The WHO identifies as the five key action areas for Health Promotion: 1. Build Healthy Public Policy, 2. Create Supportive Environments, 3. Strengthen Community Actions, 4. Develop Personal Skills and 5. Reorient Health Services. These five key action areas are described in detail on the WHO website. Please access the site here.

The action area „Develop Personal Skills“ is especially important for deducting a mission in the field of education for health. The Ottawa Charter explains that „Health promotion supports personal and social development through providing information, education for health and enhancing life skills.”

 

Salutogenesis

"What makes people sick?" This is a very important question in medical science. Scientists try to understand the aetiology of diseases and to influence it in a positive way. Psychologists as well traditionally deal with morbid influences from this perspective, e. g. in the case of stress. In the recent past, the reversion of the question has expanded the perspective.

"How do people stay healthy?". This is the critical question a scientist came to by coincidence. He had noticed that, among a traumatized group of women from a concentration camp in Germany during World War II, some women stayed healthier than others. The classical perspective („What is making them sick?“) investigated the group of mentally and physically severely traumatized women. Antonovsky, however, by examining the group of women who had stayed more healthily, tried to find reasons that had enabled them to cope better with the stressors. Antonovsky defined stressors as challenges in life that humans must cope with.
Furthermore, he wanted to verify if these reasons were also valid for other people. The critical question is if a person has resources of resistance to counter stressors. It’s a well-known phenomenon that many people are exposed to the same germs, but only a part of them fall sick. In a wave of common cold, some people get a cold while others do not. This phenomenon is usually explained with a better state of the powers of resistance of some people, which prevent a transmission of the germs. But why do some people have stronger or weaker powers of resistance than others? The concept trying to explain the origin of health and illness is called the „concept of salutogenesis“ (i. e. of the origin of health).

Stressors, resources of resistance and the continuum of health and illness. Antonovsky’s basic idea in his salutogenetic approach is that every human possesses healthy and ill parts. From his view, health and illness are two poles of a continuum.
The health of humans depends on the stressors they are exposed to and the resources of resistance they possess to counter them. The balance between straining and protective factors determines the health state (see image below).

Effect of stressors: They create a situation of stress that can or cannot be coped with and may lead to health (salutogenesis) or illness (pathogenesis) (continuum of health and illness).
Continuum of Health and Illnes
Antonovsky described his basic ideas in a metaphorical description; please read a quotation below:
"...my fundamental philosophical assumption is that the river is the stream of life. None walks the shore safely. Moreover, it is clear to me that much of the river is polluted, literally and figuratively. There are forks in the river that lead to gentle streams or to dangerous rapids and whirlpools. My work has been devoted to confronting the question: ´Whereever one is in the stream - whose nature is determined by historical, socio-cultural, and physical environmental conditions - what shapes one's ability to swim well?" (Antonovsky, 1987, p.90)

The salutogenetic approach focuses on the way in which a person copes with stressing factors positively. Here are some examples for resources of resistance that allow a positive coping with stressors:

  • Sufficient powers of resistance (immune system ) of the body against pathogens and other stressors,
  • The capacity to avoid stressors actively (to evade them through health-conducive behaviour / prevention),
  • Intelligence and mental flexibility to be able to adapt to living conditions or to actively change them,
  • Material resources to ensure protection, nutrition, shelter etc.
  • Social support in social networks (e. g. friends, family, co-workers).


Sense of Coherence. Of critical importance for the availability and the usage of resources of resistance is the so-called Sense of Coherence. Sense of Coherence describes the inner attitude of a person that enables the person to cope with stressors in a positive way. Sense of Coherence consists of three components: comprehensibility, manageability and meaningfulness (see overview below).

 
 


According to Antonovsky, an individual with a strong Sense of Coherence reacts to demands (stressors) by considering them as challenges and activating his/her sources of resistance. Someone with a weak Sense of Coherence, however, will soon consider the demand as overload.
Sense of Coherence, then, is a positive and active self-image about one’s own capabilities of coping that is combined with the confidence to be able to control and organize one’s life.
The stronger the Sense of Coherence, the higher is the probability to cope with stressors successfully and with positive effects for one’s health. Thus it is a challenge for health promotion projects in schools to help teenagers develop a positive Sense of Coherence.

HAPA model

Health education often does not show the desired success. Many risky behaviours seem to be very resistent to change, and educational interventions are often not widely accepted (e. g. smoking cessation, healthy diet).

Therefore it is important to analyze the cognitive processes that lie between the message of health promotion and health relevant behaviour. The model described below may contribute to answering the question how to proceed from the educational intervention to the desired health-literate behaviour, and in which crucial points of this process failure may be possible.
There are a number of models which try to explain the origin of human health behaviour and the possibilities to influence this attitude. There is a model integrating the elements of many other models: the HAPA model, developed at the end of the 1980s by Ralf Schwarzer in Berlin. It continues the concept of Antonovsky’s salutogensis model. The HAPA model describes various phases which an individual must pass completely in a positive sense to be able to adopt and maintain the desired behaviour (by abandoning harmful behaviour or by adopting health-conducive behaviour).

Please see the phases in the image below. A more detailed description of this model can be found on the following website: http://www.hapa-model.de/
 

As the self-efficacy expectancies are considered to play an essential role for adoption and maintenance of a health-relevant behaviour, the conditions under which this desired behaviour can be initiated and influenced by teachers or other multipliers are outlined in this overview.
Perceptions of self-efficacy are constructed in the course of life from four different sources: (1) information resulting from own successful actions, (2) experiences resulting from social comparison with others, (3.) convincing verbal feedback by important others and (4.) physiological and affective conditions.

Internet „driver’s license“:
Home remedies against acne in the internet - top or flop?
Content & goals
The activity refers to Natalya’s internet search for effective home remedies against her acne. Various internet pages promote home remedies of all kinds that are said to cure or relieve acne. But many of those hints must be considered not helpful at all from the medical point of view! This activity constitutes a form of “internet driver’s license” in dealing with acne and its remedies in the internet. The goal is that pupils learn to assess and classify the different internet sources.
Realization
- Can be integrated into classroom lessons
- The checklist for the quality of internet pages is independent from the subject and can also be used in other situations
- International links are possible.
Variations
Level of guidance for the internet search can be varied
Requirements of material and media

Interview: Acne – how was that for you?
Content & goals
The four friends in our summer camp story have made different experiences with acne. This is where this activity 3 starts. Most teenagers have or have had acne during pu-berty. The pupils will interview “acne survivors” (people above the age of 18) and evalu-ate the interview statements together. This is supposed to let them see that the typical symptoms of acne are usually fading away with increasing age and that all people ex-perience and „survive“ puberty.
Realization
Can be integrated into classroom lessons
Variations
Variations are possible, e. g. face-to-face interviews, or recording the interviews by audio or video equipment.
Requirement of material and media
Technical equipment if interviews are recorded (audio/visual equipment for recording and replaying).

Role play: “Tanned or not tanned – this is the question!“
Content & goals
Tanned skin has not always been considered beautiful and is not seen so everywhere in the world. The ideal of beauty has changed a lot in different societies in the course of time. Every culture has, up to today, completely differing perceptions of beauty. This exercise is supposed to make the pupils understand that the ideal of beauty is dependent on its perception in society. In role plays, the pupils will present the ideals of beauty in different societies, cultures and eras and will discuss in how far in former times, today and in which cultures tanned respectively fair skin were or are a sign for beauty, success, wealth etc.
Realization
- Can be integrated into classroom lessons
- Cross-disciplinary goals are possible (e. g. Philosophy, History, English, Art Educa-tion)

The Sun Health Check: Test your „sun behaviour“
Content & goals
The activity refers to the differing behaviour in terms of sun exposure and sun protection of our friends in the summer camp story. UV radiation is not only good for our skin. Therefore it is important to develop a behaviour which protects us against too much UV radiation and helps us stay healthy. The pupils should be encouraged, by means of self reflection and peer reflection, to document, reflect and discuss their own behaviour with respect to sunlight and skin health. Sources of information are the learning texts in the module and two working sheets.
Realization
- Can be integrated into classroom lessons
- International links are possible
Variations
Working in couples, self and peer reflection
Requirement of material and media

Skin Type Test: What is my skin type?
Content & goals
The activity relates to the four friends in our introductory story and their different skin types. The skin protection measures you should take depend on your skin type. Therefore, it is important to know one’s skin type. In this exercise, the pupils are to find out their skin type and to deduct from this their individual sun protection programme, as an exercise in “sun-wise” behaviour.
Realization
Can be integrated into classroom lessons
Variations

Story Telling: Perfect Sun Protection or Total Disaster?
Content & goals
The exercise refers to the four friends’ „sun behaviour“. The pupils are supposed to oc-cupy themselves with the various possible measures of sun protection by writing fictitious stories (in teams), in which they create a range of possible situations. Some of the sto-ries are supposed to present an exemplary behaviour respective to sun exposure, while others should describe variations of extremely negligent “sun behaviour”.
Realization
- Can be integrated into classroom lessons
- Cross-disciplinary goals are possible (e. g. English, Biology, Art Education)

Case report: Tracing dermatitis triggers
Content & goals
Starting point is the nickel allergy of Thelma’s friend. Substances that may lead to der-matitis can be found in all kinds of surroundings: at home, at school, in leisure activities or at the workplace. If people know these substances and their occurrence, they will be able to protect themselves against their impact. The pupils are supposed to develop awareness for substances triggering dermatitis, for the places where they can occur and for the possibilities to avoid their negative influence. For this, the pupils will invent such situations in their real environment and design a case report on this.

Experiments:
Skin-irritating substances vs. skin protection measures
Content & goals
Point of reference is the nickel allergy of Thelma’s friend. Various substances (allergens, irritants) can affect the skin and lead to (allergic resp. subtoxic-cumulative) contact der-matitis. This can often be avoided (e. g. by applying skin protection measures). In vari-ous experiments the pupils learn about the hurtful impact of (strongly) irritating sub-stances and the protective effect of skin protection measures. The pupils’ action-result expectancy will be influenced in a positive way.

Background information on the subject "skin"

The skin is the largest organ of the human body. Its surface is around 2 m². Thus it is not surprising that its weight is remarkable: about 10 kg. Its structure is rather complex as well. Our skin consists of different layers, glands, receptors, vessels and veins. All these elements are necessary to make sure that the skin works well, which is very important.

The skin fulfils a large number of important tasks within the human body. The skin has a protective function, and it is absorbing and dispensing fluids and substances. The skin regulates the body temperature and is part of the immunological defence. In the inner body regions, mucous membranes take over the protective and transport functions.
The skin provides the sense of touch and also allows us to communicate with our environment (willingly or unwillingly), for example if we frown, blush or develop goose bumps.

For more information: Structure of the skin and Funktions of the skin.

You will also have noticed that everybody's skin is different: skin type, skin colour and skin condition can be very different. There are people with dark or fair skin, with dry or oily or normal skin. There are endless variations.

For more information: Skin types and Skin texture.

Nevertheless, the strain on the skin is often similar. The skin has to deal with external influences like dirt or irritating substances, or with internal factors like genetic dispositions, hormones, life style and well-being. All these factors may have a positive or negative impact on the skin.

For more information: Influences on the skin.

For all these reasons, our skin forms an important part of our body. It has to cope with many influences and strains. That is a very good reason to take good care of our skin. And this is not really difficult. If you know what your skin needs, there is a number of things you can do yourself to keep it healthy.

For more information: Skin care.

By the way: Those who would like more information regarding skin in general, may look in the area "additional information". This area contains various hints on websites on the topic that are worth reading.

For more information: Additional information.

Skin structure

The structure of our skin is rather complex. Some skin structures are very easy to recognise; one just has to look at the skin carefully. Other skin structures, however, are only visible under the microscope.

If you look at your skin thoroughly, you will discover that the different layers of the skin are visible even to the naked eye. This external, so-called “macroscopic” skin structure is visible e. g. on our hands and feet. The palms of one’s hands and the soles of the feet are covered by hairless ridged skin. The rest of the body is covered by so-called meshed skin, where hair is growing. These differences are determined genetically.

Under the microscope you would be able to see further skin layers. This finer “inner” structure is called “microscopic structure”. The fine structure of the skin consists of three layers and can only be distinguished under the microscope. Every layer shows typical cell structures with specific tasks.

Going from the outside to the inside, the skin, which is also called “cutis” in medicine, consists of the following layers:

  1. Epidermis,
  2. Dermis and
  3. Subcutis

Every skin layer has a specific structure. The image shows the different elements of the skin. These elements are among others blood vessels, hair, hair follicles and several sorts of glands (sebaceous glands, sweat glands etc.).

For more information: Epidermis, Dermis, Subcutis.

 

Epidermis
 
The outer layer of the skin is called epidermis. The epidermis is the outer border to the surrounding world. Its thickness varies in different body regions: it is thinnest on the eyelids (0.05 mm) and thickest on the palms and soles (1.5 mm). Age, sex and lifestyle can have an influence on the thickness of the epidermis. If you walk around on bare feet a lot, the horny layer under your feet will be strikingly thicker than if you don’t.
The epidermis is built up by keratinocytes. Keratinocytes are horn cells that produce the horny substance, the so-called keratine. Keratine is water-repellent and makes the skin elastic. The epidermis does not possess blood vessels, nerves or glands. In the lowest layer of the epidermis the melanocytes are located. Melanocytes are cells that produce the skin colouring substance melanine. Melanine colours the skin; when the skin is exposed to the sun, melanine darkens the skin and thus protects it from sunlight. In this way, the UV rays cannot enter the deeper skin layers. Too much exposure to sunlight can damage the epidermis cells and cause a malignant development
.
Dermis
 
The dermis consists of loosely woven connective tissue and is therefore elastic. The thickness of the dermis also varies according to location. It is about 0.3 mm on the eyelid and up to 2.4 mm on the palms of the hands and on the soles of the feet.
Very fine blood vessels run in the dermis, the capillary vessels, which supply the epidermis and the dermis with nutriments. The capillary vessels are also responsible for the temperature regulation (heat and cold) of the body. In heat, they are dilated and thus can discharge heat; in cold they constrict and make sure that the warmth produced by the organism stays inside the body.
Furthermore, the dermis also harbours hair follicles, sweat, apocrine and sebaceous glands. Usually, every sebaceous or oil gland is connected to one hair follicle. Only around the eyes, on eyelids, lips etc. we have sebaceous glands that work without a hair follicle. Foot soles and palms of the hands don’t possess any oil glands. The oil glands produce sebum (oil), a substance that prevents the skin from drying out and makes it elastic. In addition, the dermis contains pain receptors and receptors for touch and pressure.
Subcutis
 
The subcutis consists of loose connective tissue in which, like little cushions, fat pads are integrated. It is their function to keep the body warm and to isolate it from external temperature changes. This layer is crossed by extensions of the epidermis’ solid fibres. These fibres connect the skin with the underlying tissues like retaining straps. The skin can be moved more or less above this underlayer, depending on the strength of these fibres (more on the back of the hand, less under the sole of the foot). Depending on the location, the subcutaneous tissue is followed by musculature, bones, cartilage and fat. The subcutaneous tissue also harbours the end pieces of hair follicles and receptors for pressure and vibration, the so-called Pacinian Corpuscles.
Subcutaneous tissue varies in thickness depending on the location. How many fat cells are incorporated depends on the nutritional state of a person. There is no subcutaneous tissue without fat cells. The tissue serves as protection against the cold, as energy store and as buffer against blows.

Finger and toe nails and the scalp hair also belong to the skin – they are called “skin appendages”.

  Besides the skin as described above there is also the mucosa. Mucous membranes line the insides of the hollow organs, e. g. the intestines or the mouth. Mucosa can also be found on the sexual organs. The upper coating of the male glans is a mucous membrane, for example, and the female vagina is lined by a mucous membrane without glands. Mucosa, in contrast to normal skin, does have neither a horny layer nor hair.

 

Skin functions

With a surface of 2 m² (depending on size and volume of a person) the skin is the largest human organ. It weighs around 10 kg and thus is the heaviest and the most multifunctional organ of the human body.

Our skin serves to more than just to cover us. The skin is a very important organ and fulfils a large number of functions. Here are the most important ones among them:

Skin protects us against external influences. More...
Skin protects us against external influences

One of the most important functions of the skin is to protects us against negative influences from the outside:

for example against cold, heat and radiation (especially ultraviolet (UV) radiation), these are so-called physical irritations. We may also have contact with chemical irritations, e. g. at work or in the household. Our skin also works as a buffer against pressure, blows and friction (mechanical irritations). In addition, it prevents the penetration of micro-organisms like e. g. bacteria into the body. And it makes sure that we do not lose too much warmth and humidity.

Skin is part of the immune defence system. More...
Immune defence


The skin takes over important tasks in the metabolic and the immune defence system.

With a pH value of around 5.5 to 5.7 the skin is slightly acid and forms a protective layer around the body that can fend off foreign germs. The skin also harbours defence cells that react immediately as soon as foreign bodies penetrate. You can see this in the reaction to an insect bite: the place of the bite becomes red, swells and itches. These are defence reactions initiated by the defence cells.

Skin regulates the body temperature. More...
Temperature regulation

The skin disposes of a variety of adaptive mechanisms. One of them is the capacity to support the regulation of the body temperature and the cardiovascular system by means of the blood circulation.

Thus the body avoids overheating by discharging sweat (thermoregulation). A human can sweat out up to 10 litres of liquid in a day. With the sweat, the body also discharges minerals – that’s the reason why sweat is salty. In this way, the skin does not only regulate the body temperature and the water balance within the body, but also has a significant impact on the mineral metabolism of our organism.

Skin is a sensory organ. More...
Skin as a sensory organ


Very important is the function of the skin as the largest sensory organ.

The skin allows us to perceive vibrations and pain, but also touch, pressure and temperature. There are different receptors for all these sensations (e. g. temperature and pain).
Regarding temperature and pain, there is one difference: you can get used to warmer temperatures, if the change happens slowly. This is not the case for pain, and it wouldn’t make sense either: pain has an important function as a warning signal, which should not be cut out by habituation.

Skin produces vitamins. More...
Skin produces vitamins

Human skin usually produces vitamin D as Vitamin D3 (cholecalciferol or shortly calciol) by absorbing UV B light. This vitamin is very important for humans, as it is responsible for the build-up of the bones.

Skin can absorb and discharge substances. More...
Absorption and release organ


Skin is also an absorption organ. It absorbs good and bad substances.

Dissolved substances (liquid and aerogenic) e. g. can penetrate into deeper skin layers alongside the hair follicles. Thus skin creams or drugs in the form of creams or ointments can penetrate the skin and improve the skin condition. In the same way, however, also harmful substances can enter the body.

Skin fulfils communication and representation functions. More...
Communication and representation function


Skin does not only have protective functions, but also fulfils communicative and representative tasks.

The skin determines our appearance. So some people have e. g. darker or fairer skin than others or have freckles. And wrinkles and lines appear in the course of the years and form an essential part of our facial expression. We can have laughter lines and worry lines, we can wrinkle our noses and knit our brows. In higher age, wrinkles develop as a cause of skin ageing.
The skin also reveals our feelings. If we feel angry or embarrassed, we may blush, if we get scared, we tend to look bleak. And the famous “goose bumps” show that we feel cold or that something gives us the creeps. With all these signs the skin lets ourselves and the people around us see how we feel.

The mucosa as well fulfils important tasks within the human body. The glands within the mucosa have an important transport function (e. g. of foreign bodies), and the mucosa forms a barrier against external mechanical influences.

Skin types

The skin determines our appearance to a large extent. One of the factors is the skin type or pigmentation type – in short, the “skin colour”.

Every person has his or her skin colour. It is rather important to know to which skin type one belongs to protect oneself effectively. According to skin type, different measure are important for sun protection. Whether someone has fair or dark skin, is genetically determined.

An American dermatologist developed the following scheme of six skin types in order to allow recommendations for skin protection against the sun.

Skin type 1

Skin texture

Every person's skin is different. So, depending on the specific condition of one’s skin, everybody has to find the right way to treat the skin and take care of it.

It is important to keep in mind that the skin is not something like stiff armour that stays the same all the time. Skin is ever-changing and adapts to the surrounding condition like a chameleon.

In puberty, for example, it tends to become greasy or oily. In higher age, it usually becomes dry. The individual skin condition can change any time and is never fixed for the rest of one’s life.

The skin texture can also be in a quite different state in different locations in the same person. You can have normal skin in your face, but dry skin on your hands.

Please read the following table. It describes the different skin types: normal, dry and oily/greasy skin, and combination skin.

Normal skin
Normal skin is even, rosy and possesses fine pores. There are no shining and oily, or dry and scaling areas. Humidity, hornification and desquamation (i. e. the appearance of scales) are in balance. Normal skin can often be found in young people.
Dry skin
Dry skin lacks grease and humidity in the horny layer. The skin develops scales and feels tightened. It appears blunt and brittle, especially at the cheeks and around the eyes. Dry skin mostly lacks elasticity and tends to develop fine lines and wrinkles. If the skin is very dry, it can start to itch, and cracks may appear. Dry skin is especially frequent in older people.
Oily/greasy skin
Oily skin contains an increased amount of grease on its surface. It is caused by hyperactive sebaceous cells. Greasy skin is robust, often with large pores, shining and a tendency to develop comedones and spots. Oily skin occurs more often in men than in women. It is most frequent in adolescents and young adults.
Combination skin
Combination skin is dry in some locations and greasy in others. In the face, the skin tends to be dry around the eyes and on the cheeks, while the so-called T-zone (nose, chin, forehead) shines oily. The different skin areas need specific care. This skin type is rather frequent.

More information regarding care of normal, greasy, dry or cominbation skin here.

Influences

We carry around our skin every day and everywhere. Thus we expose it to many external and internal influences.

It is important to know what influences our skin. Only this way, one can take care of one's skin appropriately, care for it or protect against some minor and major dangers.

We will list some of them for you below:

The genetic constitution determines our skin characteristics. More...

Genetic constitution

The appearance of our skin is strongly influenced by our genetic disposition.

Skin colour, for example, is inherited from one's ancestors. The genetic disposition also determines if you are sensitive for getting some skin diseases, e. g. (atopic) eczema.

If you get acne and then how strongly you may be affected by it is also often determined genetically.

Hormones have an impact on the skin. More...

Hormones

Hormones also have a significant impact on the skin.

Hormones are chemical messengers that are produced within the body and are sent through the body to initiate changes and metabolic processes. The sexual hormones are a good example: during puberty or the female menstrual cycle they increase the production of sebum in the sebaceous glands. The skin becomes oily, and comedones and spots appear.

Skin reacts to physical and mechanical irritations. More...

Mechanical irritations

Skin reacts to so-called mechanical irritations, for example blows, friction and pressure.

You all know that: if you knock against something, you’ll get bruises. Or if you wear too narrow jeans, they will leave marks on your skin. Friction can make blisters appear on the skin.

Some substances can irritate the skin. More...
Substances irritating the skin


Some substances can irritate and damage our skin. If the protective layer of the skin is hurt, the upper layers of the skin can become damaged.

In medicine, one distinguishes between weakly irritating and strongly irritating substances.

If the skin is exposed to strongly irritating substances, the skin will react immediately at the first contact, e. g. in the case of strong acids, bases or solvents (chemical irritants) or inflammable substances (physical irritants).

In the case of weak irritants the skin reacts only after repeated and regular contact. Good examples for this are water, soap, detergents, oil and grease, weak solvents etc.

There are even substances in cosmetic products that can evoke skin irritation. For this reason we recommend that you read thoroughly through the list of ingredients before you use or buy cosmetic products. Please find below a list of substances that can irritate the skin.

.

Some substances can trigger allergic reactions on the skin. More...
Allergens

Another group of substances that is able to damage the skin are allergens. Allergens are substances that may release a reaction of over-irritability.

If the skin gets exposed to an allergen, it will react to it. This is called “contact allergy”. To develop an allergy (to become „sensitized“), you usually must have had repeated contact with the allergen. This is the reason why many people with allergies have contact to the allergen some time before they actually react allergic to it.

Well-known allergies are for example allergies to nickel (in buttons or costume jewellery) or to fragrances in cosmetics, perfumes or detergents.

Climate and pollution of the air have an impact on the skin. More...

Climate and air pollution

Climate has a strong impact on skin health as well: wind, cold, heat and sunlight have an effect on the skin.

The climate can be good or bad for our skin. In winter, the constant change between cold outside and warm and dry heated air inside may dry out our skin. And sunlight, especially UV radiation, has a strong effect on our skin.

  Please read more in the module Skin and sunlight.

Our lifestyle leaves marks on our skin. More...

Life style

Life style has an additional effect on our skin. How we treat our body may show on our skin.

The skin reacts to diet, for example. So it is a good idea to follow a balanced diet. And its condition will improve if you give up smoking and enjoy alcohol only moderately, as caffeine and nicotine accelerate the skin aging process.
Skin wants to be cared for and conditioned.

Some good hints about this can be found in a separate chapter: Skin care.

Skin reacts to our mental and emotional situation. More...

Mental factors

Skin is also influenced by psychological factors.

It makes a difference to the skin if we feel relaxed and rested or completely stressed out. Skin reacts to our emotional condition.
In healthy skin, this difference may not catch one’s eye. But if you are already affected by skin problems, your emotional condition may determine whether you will have another episode of your illness or not. The skin is more sensitive in that situation and reacts rather intensive to your emotional condition.

 

Skin care

The skin is the largest organ in the human body and fulfils a number of important functions. Therefore it is a good idea to take care well of one’s skin. One part of that is to clean and condition the skin appropriately and to protect it from negative influences.

The recommended way to deal with healthy or ill skin is therefore based on three ideas:

In the first place appropriate skin cleaning must be mentioned, that means the elimination of dirt, sweat, sebum and harmful substances. More information here.
Skin cleaning

Skin cleaning is important to keep the skin healthy or to support its healing. Skin cleansers help to remove dirt, sweat and sebum from the skin. They also clear away old skin cells (scales) and support the continuous renewal of the skin.

The use of skin cleansers, however, can also lead to dry skin, reddening, irritation and itching. These undesired effects depend on the applied cleansing products and on how the skin cleaning is done.

The following aspects are important when you choose a skin cleaning product:

Synthetic detergents are especially convenient for skin cleaning. In contrast to alkaline products like soap, synthetic detergents cause less irritating reactions and itching on the skin. The reason is that their pH value of 5.5 corresponds to the pH value of the skin, while soap often has a pH value of 9-12.

If your skin is already irritated, please always take into account your skin condition. Dry skin, for example, requires the use of moisturizing products. These replace some of the fatty acids that are removed during cleaning. Sensitive skin needs mild and fragrance-free detergents. For oily or greasy skin and in the T-zone in the case of combination skin, pH neutral synthetic detergents are recommended.

Always use cleansing products sparingly and always wash them off thoroughly afterwards! And if you use moisturizing detergents, please be aware still to use a conditioning cream or ointment after washing.

  The most important hints on cleaning can be found in a separate list, please read on here

Hints for cleaning and care

The most important recommendations with respect to skin cleaning and conditioning can be found in the table below. Adequate skin cleansing and conditioning are especially important in greasy and combination skin, and in dry skin.

Normal skin
Clean your face in the morning and in the evening with cleaning milk or a synthetic detergent, and wash it off carefully afterwards.
For the body, soaps or synthetic detergents are recommendable. Day conditioning should be done with a moisturizing cream. In very cold weather or dry air it is good to use preparations that contain more fat. At night, fatty emulsions should be given the preference. Apply the cream not only to the face, but also to the rest of your body! The skin should be protected against long water exposure as well as against too hot water, chemical and mechanical irritations and sunlight.

 
Dry skin
This applies to the so-called sensitive skin. For facial cleaning, one should use cleaning milk with a high percentage in fats. For the cleaning of the rest of the body moisturizing substances are highly recommendable. Expose your body to water as little as possible: don’t shower or bathe too often, and if you have to bathe, better use oil baths. Afterwards please apply a fat lotion. Also for the face, fatty emulsions containing moisturizing substances should be used. Skin protection is very important.

 
Greasy/oily skin
The hyperactivity of the sebaceous glands, increasing the supply of
fats on the skin, enhances the development of comedones. Therefore cleaning and conditioning should aim at the reduction of the sebum
production, the inhibition of the growth of germs and a removal of
comedones. Face peeling can be recommended. Oil baths must be
completely discouraged. Watery and only slightly lubricating lotions
are recommended for conditioning. Do not apply too much cream, this
might cause spots and inflammations of the hair follicles. Human
skin is very resistant, but please never forget to protect yourself
against the sun!

 
Combination skin
Combination skin is, as the word suggests, a combination of different skin conditions: the pores with the sebaceous glands produce large amounts of sebum, but the skin between the pores is dry, and, as a third factor, the pores are distributed on the skin in an irregular pattern. Combination skins requires special care and often makes necessary to use two different products. The dry skin areas need fatty lotions (containing more grease/oil than water), while the fatty areas need to be treated with more watery lotions (containing more water than oil/grease) to prevent a blocking of the pores and the development of comedones. There are even special skin conditioners for combination skin. Further skin protection is not required.

   
The second idea is skin care: it returns to the skin the lost humidity and grease, to keep it in the ideal state or to repair it. More information here.
Skin care

Appropriate skin care contributes significantly to skin health.

When you choose skin care products, please take into account your skin condition (dry / greasy skin) and the body location (scalp, hands).


Skin differs widely, depending on the skin condition, individual skin type and body location and needs adapted cleaning and care measures. Skin on the eyelids, e.g. or in the face is completely different in thickness and consistency from the skin on arms or foot soles.

If you use the wrong skin care products, you can cause problems on skin that has originally been healthy.

protection is very important.

 
Greasy/oily skin

The hyperactivity of the sebaceous glands, increasing the supply of
fats on the skin, enhances the development of comedones. Therefore
cleaning and conditioning should aim at the reduction of the sebum
production, the inhibition of the growth of germs and a removal of
comedones. Face peeling can be recommended. Oil baths must be
completely discouraged. Watery and only slightly lubricating lotions
are recommended for conditioning. Do not apply too much cream, this
might cause spots and inflammations of the hair follicles. Human skin
is very resistant, but please never forget to protect yourself against
the sun!

 
Combination skin

Combination skin is, as the word suggests, a combination of different
skin conditions: the pores with the sebaceous glands produce large
amounts of sebum, but the skin between the pores is dry, and, as a
third factor, the pores are distributed on the skin in an irregular
pattern. Combination skins requires special care and often makes
necessary to use two different products. The dry skin areas need fatty
lotions (containing more grease/oil than water), while the fatty areas
need to be treated with more watery lotions (containing more water than
oil/grease) to prevent a blocking of the pores and the development of
comedones. There are even special skin conditioners for combination
skin. Further skin protection is not required.

   
The last component is skin protection. It serves to avoid skin diseases and strives to protect the skin against harmful influences. More information here.

Skin protection

Our skin is being exposed to many external factors that may often not be favourable. For this reason, skin, healthy or sick, well cared for or stressed, needs to be protected well against external influences.

For example, it is important to protect skin against the UV radiation of the sun.

Another important field is the protection of skin against substances that you may come up against at work (e. g. as a hairdresser), against aggressive substances in the household, and against water. The most important protective measure in these cases is to wear protective gloves.

We also shouldn’t forget to protect our skin in our leisure time. For example, who loves to do wind surfing needs to protect him- or herself not only against the sun but also against the water (especially in the beginning - then even more against the water than against the sun, except if you should be an absolute natural!) If you go skiing, please don’t forget to protect yourself, next to the protection against cold, wind and weather, also against the strong sunlight.

Dry skin and the skin of children and older persons are especially sensitive. But all skin, also healthy and normal skin, needs to be protected, not just damaged or sensitive skin. You finally want to keep your skin in its healthy state.

  By the way: More information regarding sun protection can be found in the Learning module "Sunlight".

Human skin is as individual as any human being. Therefore it is very important that you take into account your specific skin texture (dry/oily) and skin type (fair/dark).

These ideas are not only important for healthy but also for sick skin. Healthy skin gets support in this way to stay healthy. For sick skin, a careful treatment is important to let it heal again.

  You can read what to do if you are already affected by a skin disease
like acne or dermatitis in the specific chapters on these subjects: module "acne" and module "dermatitis".
     
  The chapter on “Skin health and sunlight” offers information and hints about how to deal properly with sunlight.
