How does the sun affect the skin? 

As much as the sun’s rays have benefits on the body in general and on the skin in particular, on the other hand, it also has severe complications if exposure to it is abused at times and periods of more than its average, we may see complications of varying severity.

Everyone knows the benefits of sunlight on the skin from the first months of birth, where the newborn and infant are exposed to sunlight in order for the body to benefit from it, whether the skin or bones. Ultraviolet rays from sunlight can also be used in the treatment of some skin diseases such as vitiligo. And to the extent of these well-known benefits, they have harmful and dangerous complications if the doses of exposure to them increase. I and other dermatologists have reviewed cases of varying degrees of sensitivity to these rays, ranging from an increase in the intensity of redness with burning to an increase in skin pigmentation to the point of deep skin burns such as hot water burns or fire flames, causing redness in the skin with bubbles of varying sizes and depths. It is accompanied by severe pain, like any other burn. Everyone who has been exposed for a long time to the hot rays of the sun may be exposed to everyone who went to swimming pools or sea beaches without taking the necessary precautions in advance, whether by wearing sunscreens on the head or sitting under the protective sunshades designated for that or not Apply sunscreen to the body.

There is no doubt that each of these precautions has a major role in protecting the skin from the sun’s rays and thus avoiding these rays from reaching the inner layers of the skin, causing bubbles, the severity of which varies from one case to another and from one person to another due to the type of skin and the duration of exposure. We see people with white skin more affected than those with wheaten skin because of this skin of natural protectors found in the skin that protect it from the penetration of sunlight into the inner layers and avoiding its complications, from these complications what we see starting from the increase in skin pigmentation as a result of the influence of cells in the skin to protect it and secondly This effect may reach the degree of what is called a skin burn from the sun’s rays, and this has complications that are usually accompanied by severe pain that may last for days if the injured does not take prompt treatment in time. We see this rash, especially on the areas most exposed to sunlight such as the shoulders and The back and the face, and the sweat glands may also be affected, whether on the chest or back, as they appear in the form of red-colored granules accompanied by itching sometimes. There are known skin diseases that increase in severity when exposed to sunlight, such as:

Localized lupus erythematosus that appears on exposed areas exposed to rays, and we always advise them to avoid the sun as much as possible, especially on hot summer days. Changes that you may see in certain areas of the skin such as the upper extremities of the face for fear of the onset of benign changes whose symptoms may begin in the form of red spots covered with scales that are sticky that are difficult to remove with fingernails, or they may be removed and come back again. From its diagnosis and treatment before the condition escalates and its transformation over a long time into malignant diseases with clear features and symptoms, God forbid. Finally, we advise against excessive exposure to the sun and to take the necessary precautions mentioned above.
