Sunlight is the basis of life on Earth Thanks to the rays of the sun, photosynthesis occurs in the leaves of plants - the absorption of carbon dioxide and the production of oxygen, which we breathe The sun's light kills harmful microorganisms and prevents the growth of fungi and mold Ultraviolet light promotes the production of vitamin D, which is necessary for the body to absorb calcium and phosphorus However, in large quantities, UV rays are harmful to human health That's why July 3 is celebrated as Stay Out of the Sun Day
The holiday was established to raise people's awareness of the dangers of ultraviolet radiation Stay Out of the Sun Day points out that the sun can cause many problems In addition to dermal burns and dehydration, its light accelerates skin aging and causes cancer Before saying this, scientists conducted studies of young people aged 15 to 29 years old who like to sunbathe It turned out that skin cancer is the second most common disease in this group of recipients
