Sunburn: Can I tan through glass

At the heart of sunburn is the effect of ultraviolet rays on the skin. There are three types of such rays. Those that bear the name "C", almost do not reach the earth's surface, so that seriously affect our skin can not. But the rays "B" allow you to get the desired golden hue very quickly, but in this harmful way. The most safe tan is the one that is obtained by exposing the skin to the rays "A". The truth for a strong effect in this case requires considerable time. But the result is worth it: this tan is safe and lasts a very long time.

Why the skin gets dark?

For the change in the shade of the skin, as well as the intensity of the skin, in the human body correspond special cells. They contain pigment melanin, hence the name - melanocytes. Forcing the skin to darken, they protect the body from the harmful effects of solar radiation. And the more intense the ultraviolet rays, the more the pigment produces cells. An interesting feature of these cells is that they can not only darken, but also brighten (to annoy tans) to the original state. The amount of melanin in the skin is determined genetically, under normal conditions it is maintained at one level.

Intensity of sunburn

It is known that prolonged intake of certain drugs can weaken the protective functions of the body, including the ability of the skin to produce melanin. Therefore, some people are forbidden to sunbathe. The same applies to pathologies in which the skin contains too little pigment to effectively confront the environment. No matter how many such people lay on the beach, they do not "take" a tan, dangerous ultraviolet rays freely pass under the skin and harm the body.

The most important factor for a quality tan is the height of the sun above the horizon. The breadth of the terrain plays a very important role in this matter. That's why people living in hot regions of the Earth historically have a darker shade of skin. But the height of the sun affects not only the geographical position. Time of day and time of the year are also important here. In particular, if it is a moderate climate, where the change of seasons is particularly pronounced.

Another important factor relates to the atmosphere itself. The purer and more transparent, the more rays reach the earth's surface and are reflected from it. Affects sunburn and altitude: one day in the mountains will give a greater effect than a week of stay on hot beaches. Among the snow-capped peaks, the impact of the sun's rays is so high that climbers have to use several layers of protection, special glasses and creams. But even such tools do not save them from a bright tan. And all this despite the cold prevailing among the snows.

Can I tan through glass

Even in the cold season, when it is already impossible to lie on the beach, the sun is still shining brightly and affably. Often, when his beams flood our apartments, the thought arises: "How cool it would be to sunbathe right here!". Some people, on the contrary, are afraid of too strong reaction of their skin to ultraviolet, so even in transport they try not to sit on the sunny side. The question is whether it is possible to get sunburnt through glass, bothers many. Moreover, people notice reddening in such cases, typical for a newly acquired sunburn.

In fact, most people do not have to worry about whether it's possible to tan through a window glass. Ultraviolet, of course, it misses, but this is only the first kind of sunlight. As already mentioned above, this radiation is completely harmless to the skin. Rays "A", moreover scattered by glass, do not have enough strong impact to start the process of producing melanin. To hope for some effect should be only if the person has already received a tan naturally, but he began to gradually grow pale. Then even weak rays can activate the pigment already contained in the skin, causing some darkening.

In any case, the chocolate southern shade in this way can not be obtained in any way. The maximum, what should be expected, is a slight darkening of the skin. Do not take thermal redness for the first sign of sunburn. Most likely, it will pass in a few minutes. After all, attaching a heating pad to the cheek for a while, we will also see a red speck. But no one will argue at the same time that a hot-water bottle causes sunburn. Another thing if you replace the usual windows with plexiglas. Then you can sunbathe all year round.

Do I need to defend myself?

To worry about whether it is possible to tan through glass, it is necessary only to those people who are predisposed to the appearance of pigmented spots. In this case, they can provoke anything. It is recommended to use weak protective creams. Suitable even the usual daylight, as they usually also contain a UV-filter. Ultraviolet protection is applied mainly to the face and neck - places where pigmented spots usually occur.

Also, the human body has developed a natural defense in addition to melanin. With long exposure to the sun, the skin sweats, which protects it from penetrating the ultraviolet. The above allows you to get rid of concerns about whether it is possible to tan through glass in an apartment or car. Especially since the sun's rays are in a small amount of useful and even necessary to man. Therefore, it is not necessary to defend themselves from them actively, especially in the autumn season.
