Ultraviolet Radiation

The ultraviolet radiation, or UV, from the sun not only damages the skin but also the eyes. Exposure to UV rays does not only causes sunburn of our skin, it also causes sunburn of the cornea, or what is called photokeratitis, which lasts for two days at most. Long-term exposure to UV causes cataracts and other eye problems.

In spite of all their positive uses, UV rays remain very harmful for anyone who spends a large amount of time in the sun without proper protection. The most common effect of exposure to UV rays is sunburn. Sunburn is the damage caused to skin cells when they have absorbed too much energy from UV rays. Sunburn causes blood to rush to the affected area as the body tries to cool the burn, and the damaged skin ultimately peels away. In addition to the burning pain on the skin, sunburn can ultimately cause skin cancer

The best way to combat UV rays is with bodily protection. Always wear protective sunglasses and a hat to protect the eyes. A hat will also protect hair from UV damage, as well as the skin on the face and neck.

While the best protection for the skin is long, loose clothing, this is not always practical, so the next best option is a protective sunscreen. There are many types of sunscreen, but they all have a number indicating if there protective they are against harmful UV rays. The higher the number, the more protection they provide. Always use sunscreen, even if you will only be in the sun for a ten minutes. Made sure and be smart, cover up, use sunscreen and enjoy the sunshine!
