How harmful are UV rays

These days, ‘skin protection from UV rays’ is a much-discussed topic under the sun. Sunscreens together with sunblock lotions and creams simply crowd the shelves of beauty shops. But you need to be a chemistry scholar to decipher all those ingredients mentioned on the bottles. But we all need to effectively protect our skin from ultra violet radiations somehow or other. With the ozone layer getting thinned day by day, we are increasingly under the danger zone. It is not merely when you go out to the beach that you should apply sunscreen lotions. Whenever you go out, UV rays damage your skin. They easily get inside through glasses and get reflected by sand and water. It means no place is a safe place. You are constantly under the threat of skin cancer including melanoma.

The extent of damage differs according to skin types. If your skin is more sensitive to light and thin, you are likely to get burned more. Darker-skinned people will not be burned, but will be tanned. In both cases, damage is for sure. Certain people are more prone to UV attack than others. People with many moles on their body, people with a history of skin cancer, people who live at places of high altitudes, people who have had an organ transplant etc are those under increased UV threat. Certain medications such as non-steroidal anti-inflammatory drugs, diuretics or tricyclic antidepressants and certain antibiotics also increase the sensitivity of your skin to ultra violet radiation.

Wondering about the solution? Well, never ever go out into the sun without enveloping yourself with an effective sunscreen. Ensure that your sunblock cream or lotion is labelled “broad-spectrum.” If so, it offers protection from both UVA and UVB rays. Do not get misled by the common “SPF” numbers, since such creams provide only UVB protection. Even if your contact lenses have UV shielding, it is better to wear sunglasses that provide maximum protection from UV rays as well.
