The sun and its consequences (2nd part)

In addition to what has been said before, sun causes the worst effects on skin. After a period of five hours of sun exposure, the skin may develop sunburn which causes a red and painful kin produced by overexposure to UV radiation. In most of the cases, some skin cells died and skin peels. The Science Magazine stated that five to seven people developed sunburn after an entire day at the beach. Consequently, experts have recommended the use of sunscreens. Moreover, they agree that unprotected sun exposure is more dangerous for people who have moles, very fair skin or hair, or a family history of skin cancer. Skin cancer is a skin disease which may have been caused by repeated severe sunburn or long term sun exposure. Unluckily, if this disease is not detected on time, the person could die. Experts indicate that the natural protection our body has against skin cancer is melanin. Melanin is the pigment that gives skin its colour; the darker a person is, the more melanin they have. That is why people with fair skin are more vulnerable to skin diseases.
The use of appropriate sunscreens and sunglasses would reduce the risk of developing any of the diseases above mentioned. People should be careful about self protection and persuade their kids to protect themselves from sun.
