A sunburn is a burn to the skin produced by overexposure to ultraviolet (UV) radiation, most commonly from the sun's rays. Commercial preparations are available that block UV light, known as sunscreens or sunblocks. The progression of the burn is such that typically there is initial redness (erythema), followed by varying degrees of pain, both proportional in severity to the duration and intensity of exposure. What is a burn? It's a form of injury to body tissues which is caused by heat, corrosive substances or friction. Following a burn or scald, make sure you and the affected person are safe from further burns or danger - then cool a burnt or scalded area immediately with cool water (preferably running water) for at least 20 minutes. A similar burn can be produced by overexposure to other sources of UV such as from tanning lamps, or occupationally, such as from welding arcs. Sunburn can easily be prevented through the use of sunscreen, clothing (and hats), and by limiting solar exposure, especially during the middle of the day.
Potential forms of protection include wearing long-sleeved garments or sun-protective clothing which block UV rays, wide-brimmed hats, and using an umbrella when in the sun. These have a Sun Protection Factor (SPF) rating, based on the sunblock's ability to reduce the UVB radiation at the skin: the higher the SPF rating, the greater the protection. Seek medical attention immediately.Step 7 Step 7 Seek medical careIf it's third degree, seek care immediately. The only cure for skin burn is slow healing, although skin creams can help ease some of the pain of tender burnt skin.

It is best to use a broad spectrum sunscreen in order to protect against both UVA and UVB radiation, and apply it 15 to 30 minutes before sun exposure, followed by another reapplication 15 to 30 minutes after the sun exposure begins. Immediate, temporary relief can be obtained by putting a cool, wet towel over the affected area, or taking a cold bath or shower.
The injury is limited only to the outer layer of skin (epidermis), but not all the way through. Also, removing clothes covering the burn is essential for the next step.Step 3 Step 3 Cool the burn siteCool tap water is sufficient to prevent further damage to the tissue. If it's first or second and you're worried about it, never hesitate to go to your own physician to make sure everything is okay. The burn continues to develop for 24 to 72 hours occasionally followed by peeling skin in 3 to 8 days.
If you are unsure about the severity of the sunburn, please consult a healthcare professional. Also, a small amount of heat is given off from the burn, giving a warm feeling to the affected area.
There are also numerous topical skin products that are sold over-the-counter to relieve the pain of a sunburn with a cooling effect. Extreme sunburns can be painful to the point of debilitation and may require hospital care. In many cases, the application of cold water or ice gives immediate but temporary relief from pain.

Aside from topical treatments, the pain from a sunburn may also be helped with an analgesic such as acetaminophen or ibuprofen.
Clothing can retain heat, even in a scald burn, and so should be removed as soon as possible.
If you cannot switch off the electricity: If the person has been injured by a low-voltage source (220-240 volts, domestic electricity supply) then remove the person from the electrical source using a non-conductive material such as a wooden stick or wooden chair. Chemical burns should be irrigated (washed) with lots of of water and for longer than 20 minutes. The top layer of skin may peel a day or so after the burn, but the underlying skin is healthy. For example, some areas of the burnt skin may be superficial, some partial thickness and some full thickness.
The effects on the lungs from smoke inhalation may be delayed by a few hours so a person may appear OK at first. Symptoms such as sore throat, cough, wheeze, singed nasal hair, facial burns or breathlessness may suggest there may have been smoke inhalation.
