Why do we need special clothing for UV protection? UV or ultraviolet radiation is part of the sun’s radiation that we receive as sunlight here on earth. Ultraviolet rays which are of concern to us as human beings can be separated into UVB and UVA. Until recently UVB rays were recognised as the strongest part of ultraviolet radiation and mostly responsible for producing sunburn and skin cancer. However, recent studies at Sydney University in Australia, found that UVA rays, that penetrate more deeply into the skin do more harm. This is more likely to be the cause of skin cancer. UVA has long been known to cause premature aging of the skin. This is caused by reducing its elasticity and strength, resulting in wrinkles, thinning, variations in pigmentation and broken capillaries. Both UVB and UVA rays can cause damage to the skin. Wearing clothing for UV protection is one of the best ways to avoid the sun’s damaging ultraviolet rays.
It is known that a certain amount of exposure to the sun is necessary to synthesise vitamin D within our bodies. This is for the prevention of rickets, for healthy bone growth and, in its active form, is an important hormone in regulating cell growth. It is also known that short term and long term exposure to UVB and UVA radiation can have serious consequences for human health. A good suntan was and is still looked upon as a sign of good health, whereas, the opposite is probably true. Over exposure to the sun can cause sunburn which is a mild form of radiation burn. It is estimated that one third of the time it takes for sunburn to occur, can significantly inhibit the action of the immune cells in the skin. This could compromise the body’s immune system and its ability to fight skin cancer. Continue reading ‘Clothing For UV Protection – A Reliable Defense For Premature Aging and Skin Cancer’ »
