Although you may feel healthier with a bit of a tan…your skin sure does not! The sunlight that warms our bones and makes flowers grow contains UV radiation. Too much UV radiation can damage the skin.
Exposure to UV (ultraviolet) radiation from sunlight can lead to:
Sunburn—This is the most obvious and most immediate sign of too much sun. Your skin will be red and tender, and it may swell and blister. You may even run a fever and feel nauseous from a sunburn.
Premature wrinkling and uneven skin pigmentation—Over time, too much sun exposure will cause your skin's texture to change. The skin can become tough and leathery, and you may notice more wrinkles. In addition, the sun can cause sun spots—discolorations in the skin's tone that may be brown, red, yellow, or gray.
Skin cancer—This is the most serious result of too much sun. Check your skin regularly for any changes in the appearance of moles or freckles.
To help protect your skin when you are in the sun, follow these simple tips:
Always wear sunscreen with a sun protection factor (SPF) of at least 15. Use a "broad spectrum sunscreen." This type absorbs UVA and UVB rays of the sun.
Apply sunscreen to all exposed areas approximately 20 minutes before sun exposure. Use the amounts recommended by the manufacturer. Do not forget the back of the neck, rims of the ears, and tops of the feet. Reapply after swimming and every couple of hours.
Try to avoid sun exposure between 10 a.m. and 4 p.m. This is when the sun's rays are most damaging.
Wear a wide-brim hat, sunglasses, and other protective clothing. Special SPF clothing is also available.
Do not deliberately sunbathe.
Do not use artificial tanning devices, such as tanning booths or tanning lamps.
The UV Index
The US Environmental Protection Agency and the National Weather Service put out the UV Index, a daily report on the UV radiation levels in different areas in the country. Here is how to interpret the number:
0 to 2—low danger from the sun's UV rays for the average person.
3 to 5—moderate risk of harm from unprotected sun exposure
6 to 7—high risk of harm from unprotected sun exposure
8-10—very high risk of harm from unprotected sun exposure
11+—extreme risk of harm from unprotected sun exposure
