The sun - benefits and harm: American dermatologist Marina Vinarskaya answers readers' questions
The sun is necessary to support life. However, this benefit must be used with caution, since ultraviolet rays are harmful to the skin.
UVA rays penetrate clouds, glass and the epidermis. Unlike UVB rays, they are painless, but penetrate very deeply into the skin and reach the dermal cells.
• The sun is the source of life. In small doses, sunbathing is very beneficial.
• Mood: Sunshine is an excellent cure for some forms of seasonal depression.
• Synthesis of vitamin D, which is essential for replenishing calcium in bones. Spend 15 minutes in the sun every day.
• However, in large doses, the sun can be very dangerous and cause:
• Sunburn, also known as erythema.
• Photodermatosis in the form of summer sun dermatitis, acne, as well as rare types of photodermatosis, for example, lupus erythematosus and photo-induced urticaria.
• Pigment spots, melasma (“mask of pregnancy”) or vitiligo.
• Photo-immunosuppression (herpes labialis).
• Photosensitivity.
Undesirable effects
can be long-term
• Premature aging of the skin, which is expressed in the appearance of age spots, yellowish skin color, deep wrinkles, loss of skin firmness and elasticity.
• Photocarcinogenesis (skin cancer)
PROTECTING your skin is very important!
• There are several rules for staying in the sun:
• Look for shady areas and avoid exposure to the sun during its peak hours.
• Do not leave children in the sun.
• Wear hats, sunglasses and T-shirts for you and your children.
• Apply plenty of sunscreen immediately before going out into the sun. Reapply the cream at short intervals and in large quantities, especially after swimming, heavy sweating or towel drying.
Certain foods help improve sun protection. A number of naturally occurring substances, such as carotenoids, vitamin C found in fruits and vegetables, and vitamin E, contribute to sun protection. But they are in no way a substitute for quality sunscreens.
