Sunlight can help our mental outlook and help us feel
healthier. For people who have arthritis, the sun's warmth can help relieve some of
their physical pain. Many people also think that a
suntan makes a person look young and healthy. But
sunlight can be harmful to the skin, causing immediate problems as well as
problems that may develop years later.
sunburn is skin damage from the sun's
ultraviolet (UV) rays. Most sunburns cause mild pain
and redness but affect only the outer layer of skin (first-degree burn). The red skin might hurt when you touch it. These sunburns are
mild and can usually be treated at home.
Skin that is red and
painful and that swells up and blisters may mean that deep skin layers and
nerve endings have been damaged (second-degree burn). This type of sunburn is usually more painful and takes longer to

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.

Choosing a sunscreen

creams, ointments, and sprays. Use a sunscreen that:

and B (UVA and UVB) rays.
Use lip balm or cream that has
SPF of 30 or higher to protect your lips from getting sunburned or developing
Use a higher SPF at when you are near water, at higher elevations or in tropical
climates. Sunscreen effectiveness is affected by
the wind, humidity, and altitude.
Some sunscreens say they are water-resistant or
waterproof and can protect for about 40 minutes in the sun if a person is doing
a water activity.
Applying a sunscreen
Apply the sunscreen at least 30 minutes
before going in the sun.
Apply sunscreen to all the skin that will
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
recommended on the label. Most sunscreens are not completely effective because
they are not applied correctly. It usually takes about
1 fl oz (30 mL) to cover an
