Sun poisoning is an extreme case of sunburn, a burn that occurs when\u00a0UV radiation\u00a0inflames your skin. It begins with symptoms similar to sunburn, and so it often goes unnoticed, leading to more severe symptoms and dangerous situations.\nSun poisoning is most common during the summer months and in sunny areas. Those with a lighter skin tone, specifically redheads, are most susceptible to sun poisoning.\nThis is because their body has not had a chance to produce melanin, the pigment that absorbs UV light and darkens skin (tans) to form a protective layer.\nRELATED:\u00a05 Common Sunscreen and Sun Protection Mistakes\nSun Poisoning Symptoms\nIt can take fewer than 15 minutes to get a sunburn.

More severe symptoms of sun poisoning include:\n\nSwelling\nLarge blisters\nHeadache\nFever\nDizziness\nConfusion\nNausea or vomiting\nRapid pulse and breathing\nFainting\nDehydration\n\nSun poisoning symptoms can last anywhere from two to three days, or they may persist for weeks.

If not treated early and properly, sun poisoning can increase the risk of developing\u00a0skin cancer.\nSun Poisoning Rash\nSun poisoning rash, also known as sun allergy or sun rash, can result from sun poisoning or too much exposure to the sun. Sun rash is a very itchy, widespread red rash. Small bumps, resembling the appearance of hives, can also develop.\nBlisters can also be a sign of sun poisoning.
