Sun poisoning or photo-dermatitis is basically an allergic reaction to the sun's UV rays. It occurs when the skin is exposed to sun after a long time and people with fair skin are more susceptible to this than those of a darker colouring. It can also be caused due to certain medications and skin products that make the skin more sensitive, autoimmune deficiencies such as systemic lupus erythematosus or even vitamin deficiencies.
The first signs of sun poisoning are an itchy bumpy red rash all over the body. Other symptoms include fever, nausea, vomiting, fatigue, dizziness or chills.
To avoid sun poisoning, avoid exposure to the sun, especially if you have sensitive skin. Special care should be taken for children since they are more sensitive and the effects of sun poisoning can be life threatening for them. If you must step out in the sun, or want to sun-bathe or tan your skin, then opt for mornings or later afternoons. Avoid exposure to the afternoon sun since it is the strongest at that time and burns the skin easily. If you are at the beach in the afternoon, ensure that you are lying under the shade of an umbrella or a palm tree. Always use a good sun-screen lotion to protect your skin from the harmful UV rays. Finally if you do get sun poisoning, drink a lot of water and fresh juices and apply Aloe Vera gel to the affected regions for soothing relief.
