Spring has arrived and with it sunny days, enticing us outdoors and inviting us to sunbathe. Feeling uncertain as a result of advice, which mostly encourages them to avoid spending time outdoors, many people wonder: "Is a sun tan a sign of skin damage?" The answer, according to Ad Brand from the Sunlight Research Forum (SRF), is "No", in fact the human body uses skin pigmentation in order to avoid overexposure to the sun's rays. Similar to sweating, which is the body's way of compensating for high temperatures by preventing the body temperature from rising excessively, tanning is the body's protective mechanism."
Because, Brand continued, on the one hand, the human body needs to be exposed to sunlight in order to ensure a sufficient supply of vitamin D, the production of which is stimulated by ultraviolet radiation, with 90 percent of it being produced in the skin. However, on the other hand, it is true that overexposure to sunlight causes sunburn, which does damage the skin and can lead to skin cancer. In the middle latitudes the "tanning" mechanism actually serves the purpose of helping the skin to adapt to the differing intensity of solar radiation, which varies according to season or location.
"Therefore, a sun tan is undoubtedly an indication of health," says Ad Brand emphasising that, "completely avoiding all exposure to sunlight is as nonsensical as spending excessive amounts of time tanning. It is much more advisable to spend a moderate amount of time in the sun in order to benefit from the essential positive health effects it provides us with and to avoid the risk of disease."
