Remember your childhood. Winter, summer - it does not matter, we rushed to the yard, arranged noisy games for Cossack robbers, drove on the bikes, fumbled in the snow, and just walked around exploring the neighborhood. And now? Children are busy around the clock. To school, to music school, additional English, swimming pool, lessons ... For walks in the fresh air there is no time left. And even if it remains, the children spend this time, burying themselves in the laptop / tablet / phone screen. At best - in the book. And it turned out that the current growing generation is a generation of the naughty. And the matter is this.Photo:GettyImagesScientists from the London School of Medicine and Tropical Medicine have discovered a direct link between myopia and lack of sunlight. If a child is reliably protected from exposure to ultraviolet rays by the walls of a house or school, the likelihood of developing myopia - short-sightedness - increases several times. Moreover, the child will not necessarily get glasses in childhood. It is quite possible that myopia will make itself known at a later age. The researchers turned out to be meticulous people and checked the feedback. A group of adolescent subjects increased the time in the sun. After some time, their vision was compared with the vision of their peers who led the same "cave" lifestyle. And it turned out that the latter had more prerequisites for the development of myopia than "sunny" teenagers. Scientists explain: do not underestimate the importance of vitamin D for the body. It is responsible for the quality of vision. And it is synthesized in the human body under the influence of sunlight. If there is not enough sun, there is not enough vitamin D. - Even if you add additional sources of vitamin D to your diet, it still does not have the same effect as being in the sun, say scientists. However, you should not forget about additional sources of vitamin D. It is found in eggs, fish, parsley, cheese, caviar. To a lesser extent - in dairy products. By the way, ultraviolet light penetrates even through clouds. So arguments about a cloudy winter in your area are not an excuse at all. Walk and be healthy. Read also:
