Sunburn and sun poisoning facts

  • Sunburn is an inflammation of the skin caused by overexposure to UV radiation from the sun.
  • UV radiation damages the skin and also can damage the eyes.
  • UV rays are most intense at noon and the hours immediately before and after (between 10 a.m. and 4 p.m.).
  • Immediate symptoms of sunburn are
    • hot, red, tender skin;
    • pain when the skin is touched or rubbed; and
    • dehydration;
    • several days after exposure the skin may, swell, blister, peel, and itch.
  • Most sunburns are mild and can provide relief and be treated home remedies such as
    • applying damp cloths or compresses to reduce the pain,
    • soaking in a tepid bath (with no soap),
    • gently patting the skin dry,
    • applying soothing creams or lotions,

    • moisturizing the skin.

  • UVB as well as UVA rays may cause damage to skin. UV rays may bounce off water, sand, snow, and other surfaces causing sunburn.
