The sun is bright and relaxing on the sea Long hours Many dream of an ideal summer, especially those who live in cold country, but summer fun does not avoid the risk of harmful sun rays that may cause skin burns and skin cancer.
Many people may not realize the dangers of sunburn and deal with it lightly, which the German Radiation Protection Agency has warned since it began two years ago to issue a measure of the strength of UV rays every day.
The German dermatologist Ralph von Kedrovsky said that sunburn acts as a poison to the skin. Ultraviolet radiation causes a lot of damage to the DNA of the cells of the outer layer of the skin.
The body can repair damage caused by ultraviolet light but in a limited range, but if the number of damaged cells to a certain extent due to long stay in the sun, this mechanism stops.
Sunburn often begins to appear on the skin after about six hours of intense exposure to sunlight. This starts with redness of the skin and sometimes the inflammation appears on the surface of the skin sharply, and after several days begins peeling, which is evidence of the death of damaged cells on the surface of the skin.
The most serious aspect of sunburn is the possibility of causing damage to DNA, which may cause long-term incidence of skin cancer.
Treatment and prevention
The first step to be taken when sunburn is to get away from the sun immediately and then try to cool the skin by cold bath or put wet tissues with water on the skin. Patients with heart and circulatory system are advised to use lukewarm water rather than cold.
The next step is to use some simple products such as yogurt and cold tea packs and place them on the skin.
The principle of "prevention is better than cure" is very useful to avoid harming the sun while enjoying it. Sun protection products should be used. Do not expose the skin to direct sunlight for long periods and be careful to wear sun glasses and hats to protect against harmful rays.
The risk of burns is not only due to direct exposure to sunlight, but light sand and water bodies reflect ultraviolet radiation at varying degrees, as beach sand reflects up to 25% of the sun's radiation.
