Sun Poisoning

Sun poisoning, also known as sunburn, is the highest degree of burns caused by exposure to the sun. Though it looks simpler, it might possibly cause a huge damage if not treated properly. This sun poisoning usually starts as a regular sunburn and hence people tend to ignore the initial symptoms.

Some people have really sensitive skin, especially the fair-skinned people who have had less exposure to sun in their lifetime. Also, the people that have low melanin are more prone to sun poisoning. Melanin is a pigment that absorbs UV light and also sometimes forms a protective skin layer to protect it. This production is usually higher in the case of people with darker skin tones. This sun poisoning can happen on any part of the body and sun poisoning on the lips is very painful. This poisoning is also known as photodermatitis or photoallergy and causes severe rashes by exposure to the sun for a long time.

What is a Sun Poisoning Rash?

The sun poisoning rash is the after effects of the sun poisoning. Usually, the people that are sensitive to the sun get sunburnt. In some cases, the sunburn takes a bad shape and turns into sun poisoning. The normal sunburn may cause things like facial swelling, swollen eyes, swollen ankles, itchy eyelids, painful skin etc. but the sun poisoning has a lot more effects like headache, nausea, rashes, vomiting etc.

Rashes are the main and the first thing that is noticed in the case of sun poisoning. This rash is mainly a red bump on the skin that has been burnt by the excessive exposure to sun. In some people, it takes as less as fifteen minutes to develop sun poisoning rashes. This rash is itchy, red, bumpy and sometimes might lead to blisters that have pus filled in it. This holds true especially in the case of sun poisoning on the lips. In some cases, extreme itching of the rash might lead to bruising which might leave scars on the skin. The sun poisoning rash can also be followed by facial swelling, bumps on arms, extreme itching on chest and feet, inflammation in the eyelids with swollen eyes, cold sores, diarrhea, fever and much more.

In the extreme cases, the rash might lead to skin cancer if the skin has been exposed to the light for a long duration of time. The bumps formed on the skin are usually in clusters and the areas including chest, legs and the arms may give out hives like appearance. The skin swells and there is a slight pain and tingling sensation in the mild case of sun poisoning. If the symptoms like diarrhea, fever, dehydration, headache happens, consultation of a doctor becomes the most important thing. The bumps and the rashes later dry out and the skin starts crusting and cracking. In many cases, the cracked areas tend to bleed and are very painful.

Causes of Sun Poisoning

The main cause of the sun poisoning rash in the people is the lack of melanin that saves us from the effects of the harmful ultraviolet rays. This pigment is the lowest in case of fair-skinned people. Because of this pigment, the people with darker skin tones are the ones that rarely get sun poisoning in comparison to the ones with a fairer skin tone. Melanin is also responsible for giving color to the skin, eyes and hair in all the mammals including humans. Also, the people who are rarely exposed to the sun are more at risk of getting harmed by the ultraviolet rays.

In some individuals, the skin is more sensitive to anything around them and this is usually inherited. But in some cases, the external factors are also responsible for things like these. More the exposure to sun, more severe is the sun poisoning. There are also some drugs that may lead to the skin becoming more sensitive in the case of many people like thiazide diuretics, hexachlorophene, sulfa, lemon oil, musk ambrette, benzoyl peroxide, photoreactive dyes and much more. These chemicals are present in the day-to-day products like perfumes, sunscreens, antibiotics, dyes etc. and one should check the ingredients before using any such products.

There are some plants which may also lead to the sun poisoning. For example, Giant Hogweed Sap if comes in contact with the skin, makes it more susceptible to the harmful effects of the ultraviolet rays. Similarly, a common garden plant, Common Rue, is also responsible for sun poisoning and rashes. Even if you have a non-sensitive skin, continuous exposure to sunlight can cause sun poisoning. So, it is advisable to stay safe and take preventive measures beforehand.

Effects of Sun Poisoning
