The sun rays are needed for our body, but on the other hand, they can seriously harm it. The skin is mainly exposed to their undesirable effects. See for yourself what are the threats of inconsiderate use of the sun and how to deal with the effects of too long sunbathing.
How does sun radiation affect the skin?
Thanks to the sun’s rays, vitamin D is produced in the body, the use of which affects the functioning of the skeletal, circulatory, nervous and muscular systems. However, too long skin exposure to the sun can lead to serious skin changes. They include:
- uncontrolled keratosis and roughness,
- thickening and drying of the skin,
- loss of flexibility,
- deepening of wrinkles,
- increased seborrhea.
Types of radiation vs the skin
There are three types of radiation:
- UVA – reaches the skin to the greatest extent, penetrating even through the glass. It causes skin ageing and erythema formation, triggers photodermatitis during the use of photosensitizing preparations.
- UVB – although it affects the production of vitamin D, it is the most dangerous for the skin; it can cause irreversible changes in our skin.
- UVC – this is the most harmful type of radiation, luckily it reaches the Earth to a very small extent because it is absorbed by the ozone layer.
UV radiation should be avoided from 10 am to 4 pm, because then it has the most dangerous action. Remember that you must protect your skin especially in May, June, July and August. In September, the intensity of sunlight decreases. If you go skiing, you should also watch out for UV rays. Reflecting off the snow, they fall on the skin with a double force.
How to protect the skin against the sun and its effects?
In this case, prevention is the key to success. You should sunbathe in the morning or late afternoon, the skin should be protected with a cream that has a sufficiently high filter. What’s more, the head and eyes should be protected with a hat and glasses. During the whole summer, you should eat fruit and vegetables that are natural antioxidants and contain vitamin E.
