What Causes Sun Poisoning?
Sun poisoning is basically caused by prolonged exposure to the strong and harmful ultraviolet (UV) rays of the sun. It occurs most commonly in hot summers when the ultraviolet rays are the strongest. Moreover, light-skinned people are more at risk of suffering from sun poisoning. This is due to less amount of protective melanin pigment. However, it can affect anyone who spends long hours in the sun. The risk of having sun poisoning increases drastically by the use of certain chemicals, drugs, and cosmetics. Drugs, such as sulfa-containing drugs, tranquilizers, anti-hypertensives, drugs used for diabetes mellitus, anti-fungal, and birth control pills, can trigger sun poisoning. Also direct contact with substances like detergents, deodorant bar soaps, shampoos certain cosmetics and toiletries, followed by the exposure to sun rays may lead to sun poisoning as well. In addition, certain chemical that are found in vegetables and fruits can also be responsible for the specific photosensitive reactions.
Sun poisoning is of two types. In the first type, the skin reacts to the sun rays by having red, bumpy skin associated with rashes. Whereas in the second type, heat stroke, sunstroke, and heat prostration occurs. This is because of dehydration and the loss of electrolytes that occurs in sun poisoning.
The severity of the symptoms produced by sun poisoning depends on the duration of the exposure to the ultraviolet rays, intensity of the sun rays, as well as the capacity of the body to withstand the sunrays. These symptoms may appear to be either mild or pretty severe.
