Protect Your Skin: How to Avoid Sun Exposure

IMAGE You may feel healthier with a bit of a tan, but your skin does not appreciate it. The sunlight that warms our bones and makes flowers grow contains ultraviolet (UV) radiation that can damage the skin.

Here's Why:

Exposure to UV radiation from sunlight can lead to:
  • Sunburn—This is the most obvious and 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 severe 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. The more sun exposure and sunburns you have, the more your risk of skin cancer increases. Learn about the proper way to check your skin for any changes in the size, texture, or color of a mole. The Skin Cancer Foundation recommends you check your skin every month.
A dermatologist can check for unusual blemishes, moles, and other skin lesions for signs of cancer. Talk to your doctor about how often you should have regular screenings. They are painless and only take a few minutes.

Here's How:

This may include:
  • Avoiding sun exposure between 10:00 AM and 4:00 PM. This is when the sun's rays are most damaging.
  • Not deliberately sunbathing.
  • Not using tanning devices, like tanning booths or tanning lamps.
In general, it is best to avoid spending too much time in the sun. If it is unavoidable, follow these guidelines:
  • Use broad-spectrum (UVA and UVB) sunscreens with a sun protection factor (SPF) of 30 or more on skin that will be exposed to the sun. Apply sunscreen to all exposed areas approximately 30 minutes before sun exposure. Use the amounts recommended by the manufacturer. Do not forget the back of your neck, rims of your ears, nose, and tops of your feet. Reapply every 2 hours, or after swimming or excessive sweating.
  • Use a protective lip balm.
  • If you are at the beach, sit under an umbrella or use nearby shade.
  • Choose hats and clothing with a high UPF (ultraviolet protection factor). This is the amount of the sun's UV rays that are being absorbed by your clothing before they get to your skin. A rating of 50+ offers a lot of sun protection. Consider clothing that has been treated with special UV absorbers or chemical sunblock to offer more sun protection. Be careful, as these may lose their sun protective qualities over time.
  • Choose clothing made from tightly-woven fabric. This will absorb more of the sun's UV rays. Darker colors absorb rays better than light colors. Hold clothes up to the sun to see how much light comes through. Clothes that do not let much light through will be more protective. For example, a dark denim shirt offers more protection than a white t-shirt. Long-sleeved shirts and long pants will give more protection.
  • Wear a wide-brim hat and sunglasses. A hat with a six inch brim all around is best. Choose sunglasses that block both UVA and UVB rays.
