Sun poisoning is a non-medical term for severe sunburn.
This type of sunburn may include red, painful skin with swelling and blisters. A child with sun poisoning may also have other symptoms, such as fever, chills, or nausea.
Sun poisoning is also sometimes used to describe the rash that certain people get because they have a sensitivity to the sun. These people, especially young adult women, have polymorphous light eruption.
