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.
A 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 heal.
Other problems that can be present along with sunburn include:

Home treatment measures may provide some relief from a mild sunburn.
A sunburn can cause a mild fever and a headache. Lie down in a cool, quiet room to relieve the headache. A headache may be caused by dehydration, so drinking fluids may help. For more information, see the topic Dehydration.
There is little you can do to stop skin from peeling after a sunburn—it is part of the healing process. Lotion may help relieve the itching.
Other home treatment measures, such as chamomile, may help relieve your sunburn symptoms.
Try a non-prescription medicine to help treat your fever or pain:
Talk to your child's doctor before switching back and forth between doses of acetaminophen and ibuprofen. When you switch between two medicines, there is a chance your child will get too much medicine.
Be sure to follow these safety tips when you use a non-prescription medicine:
Home treatment may help decrease pain, prevent infection, and help the skin heal.

Call your doctor if any of the following occur during home treatment:
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 colour is.
The best way to prevent a sunburn is to avoid sun exposure.
Stay out of the midday sun (from 11 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:
You should start protecting your child from the sun when he or she is a baby.
If you can't avoid being in the sun, use a sunscreen to help protect your skin while you are in the sun.
Be sure to read the information on the sunscreen label about the SPF factor listed on the label and how much protection it gives your skin. Follow the directions on the label for applying the sunscreen so it is most effective in protecting your skin from the sun's ultraviolet rays.
Sunscreens labelled "water-resistant" are made to protect people while they are swimming or sweating. The label will say if the sunscreen will protect you for 40 minutes or 80 minutes.
Remember that skin that is healing from a sunburn is sensitive to more damage from the sun, so be sure to prevent more sunburn in those areas. The following tips about sunscreen will help you use it more effectively:
Do not use tanning booths to get a tan. Artificial tanning devices can cause skin damage and increase the risk of skin cancer. If you want your skin to look tan, try a sunless tanning cream or spray that makes your skin look tan. And keep using sunscreen when you are in the sun.
