People need protection from the sun! The sun laughs at us and that pleases us; we like the idea of just enjoying it. We need sunlight Sunlight activates our metabolism, promotes our circulation, activates the formation of the vitamin D that is so important for bone growth and enhances our feeling of general well-being.
However, sunlight has its drawbacks too. The dangers are well known: as the ozone layer of the earth's atmosphere gets thinner, an increasing amount of dangerous UV light penetrates to the earth's surface. The permanent reduction of the ozone layer, our natural sunglasses as it were, by some 10% over the past 30 years has had enormous consequences: already today people are feeling the effects of long-term exposure to UV radiation. The risk of sun allergy, damage to the skin from sunburn as well as skin aging and chronic radiation damage is increasing all the time.
| Solar radiation | Possible damage | | UV-A | Skin aging, sun allergy (Mallorca acne) | | UV-B | Sunburn, chronic radiation damage
| | UV-C | Severe sunburn, high risk of consequential damage
| | Infra-red | Overheating of the skin

How much sun is beneficial? The dangers associated with solar radiation are often underestimated, because people want a quick tan. There are in fact some easy rules to follow if you want to protect yourself from the dangers of overexposure.
The time of day and the duration of exposure to the sun are the decisive factors. Each type of sun has its own time limits.
The first step to enjoying sunshine is a healthy self-assessment of one's skin type. Am I thin skin or thick skin Am I pale or dark complexioned? How much sun can I take without getting a sunburn? These questions should be answered honestly if they are to be helpful. (Further information on sun types under "Safe Sunbathing" below).
As a general rule, however, the following should be taken into account: the more sensitive the skin, the shorter the recommended sunbathing time.
The use of sunscreens can prolong these times, depending on the SPF (Sun Protection Factor) of the sunscreen.
If, for example, the recommended exposure time to the sun is 20 minutes, you can multiply this by the SPF – e.g. 20 x SPF 10 = 200 minutes, maximum. Repeated application of the sunscreen however does not prolong this time again. If you just adhere to this simple rule, your skin will benefit enormously.
The right sunscreen for the right application and careful use of the sun will provide protection from radiation damage.
