Exposure to the sun

Solar radiation, absorbed by the skin tissues, epidermis and dermis, has the effect of giving us a tanned complexion and at the same time the pleasant and healthy appearance that we all desire. Our organism is able to protect itself from the sun through various mechanisms, including that of melanin, which colors the superficial layers of the skin to protect itself from the sun's rays, of urocanic acid which contributes to protection, and of the increase in thickness of the corneum due to the production of keratins, which increase skin thickness. The sun's rays (1) penetrate the epidermis, triggering protective processes. These processes also cause the formation of Histamine which, together with other substances with an inflammatory action, probably prostaglandins, reaches the blood vessels triggering a skin reaction which manifests itself within a few hours, in the form of sunburn, which in most cases serious, it becomes sunburn. Hence the importance of the following golden rules for exposing yourself to the sun without harm. The golden rules for correct sun exposure 1) Exposure to the sun must initially be very gradual, in order to give melanin time to produce its protective pigments. This means that, if you arrive at the seaside still pale, exposure to the sun from the first day for the whole day or even just half a day is definitely too much. 2) Don't expose yourself to the sun during the hours when the sun is brightest. too loud (from 11.30am to 4.30pm). 3) Protect the skin in a natural way, avoiding synthetic filters (2) on whose action we still have no certain information over time. However, these are substances that are not recognizable as self by the body and therefore potentially risky. 4) Use hats, t-shirts and umbrellas, especially for children. &` gradual exposure is very important, especially for children, only during safe hours when the reactive effect of the sun is stored in the dermis and the child who has suffered sunburn will be more sensitive even as an adult.
