Protecting Your Skin From the Sun
Protecting your skin
Most skin cancer can be prevented. Use the following tips to
protect your skin from the sun. You may decrease your chances of developing
skin cancer and help prevent wrinkles.
Although people with darker skin don't sunburn as easily, they can still get skin cancer. So it's important to use sun protection, no matter what your skin color is.
Avoid sun exposure
The best way to prevent a
sunburn is to avoid sun exposure.
Stay out of the midday sun (from
10 in the morning to 4 in the afternoon), which is the strongest sunlight. Find
shade if you need to be outdoors. You can also calculate how much
ultraviolet (UV) exposure you are getting by using the
shadow rule: A shadow that is longer than you are means UV exposure is low; a
shadow that is shorter than you are means the UV exposure is high.
Other ways to protect yourself from the sun include wearing protective
clothing, such as:
Hats with wide
4 in. (10 cm) brims that cover
your neck, ears, eyes, and scalp.
UV ray protection, to prevent eye damage.
Loose-fitting, tightly woven clothing that
covers your arms and legs.
Clothing made with sun protective fabric. These clothes have a special label that tells you how effective they are in protecting your skin from ultraviolet rays.

be exposed to the sun, including the nose, ears, neck, scalp, and lips.
Sunscreen needs to be applied evenly over the skin and in the amount

they are not applied correctly. It usually takes about
