Sunburn, also called erythema, according to the Food and Drug Administration (FDA), is the body's response to overexposure to ultraviolet (UV) light.

Exposure to the sun's UV radiation has been associated with approximately 90% of nonmelanoma types of skin cancer, the Skin Cancer Foundation says.
The sun also causes most melanomas.
One in five Americans will develop skin cancer over a lifetime, according to the foundation.
2. I've already got sunburn. What should I do?

If you miss a hard-to-reach spot on your body or lose track of time and forget to reapply, you can find yourself with a painful sunburn.
If you do get sunburn, you can try taking cool baths or showers, moisturizing with products featuring aloe vera and soy and taking pain medication like aspirin, the American Academy of Dermatology (AAD) says. Also, make sure to drink plenty of water to prevent dehydration.

Even if you do apply sunscreen, you could still wind up with sunburn if you are outside for a long period of time. If you do, both a cold bath and aloe vera can help soothe the pain. (iStock)
If you have blisters, do not pop them.
3. What about tans? Are those considered sun damage?
Tans are technically considered sun damage.
"There is no such thing as a safe tan," the FDA warns, explaining on its website that a tan is a sign of skin damage.

That’s why it is so important to wear sunscreen with at least SPF 30 to protect your skin.
4. What are the symptoms of sunburn?
The main symptom of sunburn is redness of the skin.
When you have sunburn, the part of the body where it is located is often tender, painful and warm to the touch.

If you have a darker skin tone, you may not notice sunburn right away, according to the FDA, and it can take many hours for physical signs of a burn to appear on the skin.

5. How does the body try to fight against sun damage?
The body increases the production of melanin, which is pigment that determines the color of hair and skin, according to the AAD.
In general, sunburns happen to people with less melanin, while those with more of it may tan, the group explains.
With sunburn, skin cells are damaged by UV rays, and the body sends blood to where it has been hurt. So, it causes skin to appear red and feel hot, the FDA says.
The itchiness and peeling associated with sunburn is a result of white cells getting rid of the cells that have been damaged, according to the agency.

To lower your risk of getting sunburn, apply sunscreen with an SPF of at least 30 in regular increments and wear protective clothing while out in the sun. (iStock)
6. Is there anything people can do to reverse sun damage once it’s been done?
"The truth is, the skin has a long memory," dermatologist Dr. Lisa Chipps says on the Skin Cancer Foundation website, noting that sun damage is "more or less permanently recorded in it."
She suggests using a topical retinoid like tretinoin and trying laser treatments.
People can also try methods like microdermabrasion, chemical peels and topical antioxidants.
7. What can I do to lower my risk of sun damage?
To lower your risk of sun damage, wear sunglasses and broad-brimmed hats while outside, use a broad-spectrum sunblock with an SPF of at least 30 and avoid the sun from 10 a.m. to 4 p.m., the American Cancer Society advises.
