Sun poisoning doesn't really mean you've been poisoned. It is often the term
used for a severe case of sunburn. This is a burn from
ultraviolet (UV) radiation that inflames your skin. Sun poisoning can also
refer to other reactions. Two examples are polymorphous light eruption and
solar urticaria.
Severe sunburn or sun poisoning can cause symptoms such as:
Polymorphous light eruption (PMLE). At least one in 10 Americans is affected by PMLE, a reaction that does not appear to be linked to drugs or diseases. More common in women than in men and beginning at any age, PMLE occurs in people who are susceptible and are exposed to intense sunlight that they are not used to. For example, people living in northern climates could experience this if taking a winter vacation in a tropical climate.
In some cases, this reaction gets better each year, but some people have reactions that become more extensive without treatment. And, how much sunlight individuals can tolerate varies from person to person.
Symptoms are a severe skin rash, usually appearing within 30 minutes to several hours of going out in the sun. The rash may be itchy and have these characteristics:
Other treatment or prevention for either type of reaction may include:
Limit exposure during the hottest hours of the day -- between 10 a.m. and 4 p.m. And remember that water, snow, and sand can intensify damaging rays of the sun. Finally, make sunglasses, a hat, and protective clothing standard sun gear.
