Sometimes clouds really block ultraviolet rays, but you should not always count on this. Most often, they still miss some types of ultraviolet rays - and they reach the surface of the earth.

There are even those clouds that reflect ultraviolet light and thereby enhance its effect.

If you do not see the sun, this does not mean that it is inactive. So people in the mountains are deceived: the sky is covered with clouds, snow lies around - what kind of sunburn can we talk about? But at high altitudes, ultraviolet rays more easily and quickly reach the ground - and the skin. In addition, snow reflects rays - this makes them more aggressive. One application of cream is not enough.

It is necessary to constantly update it on the skin, and also be sure to wear glasses and clothes with long sleeves.

So you are sitting in the car, listening to music, the sun is shining, you haven't put on your glasses, and you forgot to use sunscreen. What for? You do not plan to get out of the car? And this is a big mistake.

There are three types of ultraviolet rays: UVA, UVB, UVC.

UVC rays do not penetrate even through the atmosphere - there is nothing to fear. But the other types of rays contribute to aging, the appearance of wrinkles, sunburn and the development of skin cancer. So, windows stop exposure to UVB rays, but at the same time pass UVA.

The New England Journal of Medicine published a photograph of a man who drove a truck for 25 years. One half of his face looked quite smooth, overall his skin condition was consistent with his age.

The second half - it was she who was exposed to the sun for 25 years - was covered with wrinkles, because of this the man looked at least ten years older.

A large study was conducted in Australia. Two groups took part in the experiment: the first applied sunscreen every day, the second applied occasionally, as needed. After 4.

5 years, the researchers found that in the second group the number of age spots and wrinkles increased, in the first group they did not find signs of aging.

The sun's rays damage the skin fibers - elastin. When the fibers break down, the skin begins to sag, stretch. Some people attribute this to normal age-related changes, others to bad heredity. Sometimes it’s true, but sometimes it’s the sun.

Try to use sunscreen every day, especially in spring and summer. Choose the degree of protection based on your skin type, and don’t go crazy and buy creams with SPF 70 or 80. Stop at 50. The Food and Drug Administration claims that there is no sufficient evidence of the effectiveness of products with a degree of protection above 50.

But it’s not enough to apply sunscreen every morning.

It must be constantly updated, preferably every two hours, especially if you are swimming or sweating actively.

Here is another (and main) reason to make regular application of cream with SPF a good habit.

According to The American Cancer Society

, the constant exposure of UV rays to the skin (including in a solarium) can lead to the development of skin cancer.

People who live where the sun is warm and shining all year round are more likely to get skin cancer.

But do not think that since you rarely appear on the beach, you are not at risk. When you go to work, ride in a car or walk with a dog, ultraviolet rays still fall on your skin.

Sunscreen is important, but don’t forget to wear hats, light, light clothing with long sleeves, and try to minimize exposure to direct sunlight. This is the best prevention of aging and the development of skin cancer.

  • UV rays are aggressive between 10:00 and 16:00;
  • UV rays are especially strong in spring and in summer;
  • the influence of UV rays decreases with distance from the equator;
  • in the mountains there are more UV rays and their influence is stronger.

And yet:

  • ultraviolet rays penetrate through the clouds;
  • UV rays are reflected from water, snow, sand, grass, metal - this leads to increase their exposure;
  • the strength of UV rays in each country and each city is different. Therefore, The National Weather Service and The Environmental Protection Agency (EPA) introduced a new indicator - the UV index. This helps people understand how dangerous the sun is on a particular day at their location. The UV index scale is from 1 to 11 points.

    The higher the number, the stronger the exposure to UV rays and the higher the likelihood of a sunburn. You can find out which UV index is in your city on weather forecast sites or even in the built-in applications on your smartphone.
