9 Errors on sunbathing and protection
The sun is important for our immune system, for the formation of vitamin D and not least for our mind. No wonder summer is attracting people outside. There are many mistakes about how to deal with sun and sun protection. Sun protection is important – that has now been around. But not all the wisdoms that are in circulation are true. Here is a list to clear up with common mistakes.
1. After-creams prolong the protection time
Not correct! The effect of sunscreens lasts only for a certain time. That is, by repeatedly applying a lotion – especially after bathing – you can renew the protection, but not lengthen it. It is also wrong to say that sunscreening is no longer necessary when the skin is tanned. The tan provides only a certain protection against the aggressive UV radiation. Even tanned skin is therefore damaged by intensive irradiation – only the consequences become visible later, for example in the form of premature aging and age spots.
By the way: If sun protection as well as mosquito protection is necessary, then always apply the sun protection and the (liquid) mosquito repellent over it.
2. In the shade you do not get sunglasses
Not correct! The widespread opinion, that in the shadow one does not need to apply cream, is also not true. Up to 85 percent of the radiation intensity is reflected by sand, water or buildings. And sunshades or clouds do not keep the rays of the sun completely. This is the reason why sensitive people get a sundress , even if they spend the whole day at the beach under a screen. Therefore, even those who do not go into the direct sun must apply cream.
The good news: You can also brown in the shade – although slower, but more gentle and even! And another tip: During the lunch time with the particularly intense sun exposure best not to stay outside.
3. In the water one is safe
That’s not true! The opposite is the case – water is particularly dangerous, since the surface of the water reinforces the rays. This means that the sun has a much stronger effect – up to half a meter below the water surface: up to 60 percent of the UVB and even 85 percent of the UVA rays are still there. Especially tricky: as the skin is cooled while swimming , the sun is often noticed only when the back is already reddened. It is therefore recommended to use a water-resistant sunscreen for swimming.
Waterproof products keep better and protect the skin better from chlorine and seawater – but also here the sun protection has to be renewed regularly by repeated moisturizing. In the case of children, even a special swimwear with UV protection should be used.
4. Clothing protects from the sun
No! Certain UV rays also penetrate through textiles. In particular, tight and light shirts or a wet fabric let the rays through. For example, the skin can be damaged under a light bikini made of thin material. Sun protection products should therefore be applied half an hour before sunbathing also under the bikini or bathing suit.
Tip: Detergents with sun protection are available on the market, which – after repeated washing – make the clothing sun-proof. It is also helpful to wear wide and rather dark clothes for protection. In the trade, special sun protection clothing with a light protection factor of 20 to 40 is available, which is impregnated with light protection substances. And do not forget the head guard and the sunglasses!
5. Sunblocker provide protection throughout the day
That’s not true! The name deceives: A Sunblocker can not block the sun endlessly, but stands out only by a particularly high light protection factor (30 and more). The danger is that many people feel securely protected and forgetting to replace the sun protection at regular intervals and, above all, apply it evenly.
6. Only one sundance is dangerous
Incorrect! Responsible for a sunglass are the energy-resistant UV-B rays. The long-wave UV-A rays, on the other hand, are responsible for the tanning of the skin, but also for the skin aging and the increased risk of skin cancer. Even without sunglasses, the UV radiation can harm the skin: the longer you are exposed to the radiation, the higher the risk of lasting damage. Too much sun and heat can also lead to a sunsthiness , which manifests itself by circulatory complaints and nausea .
7. Sunscreen with high SPF prevents tan
That’s not true! Many people think that a sun protection agent with high SPF prevents browning – and instead use products with too low a factor. But also with a strong sun protection one becomes brown, and gentler still to it. A high light protection factor protects against sunglasses and helps to keep the tan longer.
8. Sun allergies come from greasy creams
True, but only partially! Solar allergies have quite different causes: drugs , fragrances, chlorine or salt water, but also a hereditary predisposition can lead to allergic reactions to the UV-A rays in sunlight. Oil-containing light stabilizers can also cause solar energy and lead to so-called Mallorca acne (or specialist acne aestivalis). Solar allergies can therefore arise through a fatty suncream, but do not have to.
Problematic are, above all, sun protection products in creams and emulsions , since these contain emulsifiers which promote an allergic reaction. In the case of a Mallorca acne, a sun gel with a high UV-A light protection, which is free of fat and emulsifier, therefore helps. Caution: also for skin care products and after-sun products make sure that they do not contain emulsifiers. They can adhere to the skin for more than 24 hours and, in combination with UV radiation, also lead to incompatibility reactions later.
9. Self-tanning agents protect the skin
No! The tan from the tube offers no protection from the sun rays, because self-tanning has only a cosmetic effect. They combine with components of the human upper skin in the so-called horny layer and color the skin surface brown – the skin’s ability to protect from the sun does not change anything.
