Sun vs Skin. Is UV Radiation Really So Dangerous?

Hey!

Even though summer’s over, the topic of the sun-triggered skin diseases keeps recurring. Regrettably, sunbaths aren’t so good for our bodies. Yes, the sun boosts vitamin D production. However, it doesn’t mean we can fry in the sunlight all day long. Check diseases you are exposed to after getting too much of the sun.

When do you need the sun?

Kids would probably say you need it for summer and playing outside. As I’ve mentioned, the sun enhances vitamin D production which is extremely important to the body. What’s more, it helps treat some skin conditions, makes us feel a nice warmth and see colors. On the other hand, the sun can cause burns, cancer and even the stroke. It can intensify atopic dermatitis, psoriasis and acne rosacea. That’s why protecting skin from the harmful radiation is so crucial. What do I mean?

Mysterious symbols: UVA, UVB, UVC

These are types of the sun radiation. They are different in the wave length, the speed of reaching the Earth and results they cause. UVA rays deeply penetrate the skin, causing very serious damage. UVB radiation can trigger even worst results and lead to skin photoaging. On the one hand, it is harmful to the eyesight. On the other hand, it takes part in the production of vitamin D. Interestingly, UVB radiation is used in dermatological treatments. UVC is the shortest and – theoretically – should be blocked by the ozone barrier. This type of light is used in bacteriostatic lamps.

How does the skin protect itself from UV radiation?

The skin has a few sun protection methods. One of them is… suntan. The tan – caused by the visible light – appears right away and lasts up to 24 hours. The proper tan occurs after two days and is connected with the growth of melanocytes – cells responsible for skin tone and pigmentation spots. The darker the skin, the better the protection. Skin thickening is another method. Photoaging, dryness, elasticity loss, wrinkles and discolorations are the reactions to long sunbathes without SPF creams. Sweating is another way of skin protection against UV radiation. Acids, included in the sweat, absorb UVB rays.

Should we give up on sunbathing? No way! Let’s just do it wisely.
