Perhaps the greatest advantage of sun bathing is that it take you away from your usual environment; this in itself to reduce stress. Another advantage is that it relaxes us and relaxation of any kind is good for the health. To benefit from the valuable ultra violet rays of the sun, which generate Vitamin D in the system, it is not necessary to lie directly in the sun – the rays can be of benefit even if you are in the shade, provided that you are not wearing thick clothing.
Over exposure to the sun can be dangerous and can lead to sunstroke. For someone used to the British sun, exposure to the sun say in the Mediterranean or the tropics should be by gradual stages. When there is an enormous amount of perspiration from the body, it is essential to replace both the water and salt. Unless this is done, a person is liable to collapse. A drink of water with a dash of salt, sugar and lime is excellent.
The eyes are the one part of the body that must be protected during sun bathing. If the eyes are properly protected from the sun, the body will not suffer any harm. There is no foundation for the popular belief that the head and back of the neck must be protected from the sun. After acclimatization the body can take any amount of sun provided that the eyes are properly protected.
The fact is that sewage in sea water has never been scientifically proved to be a serious health hazard. The salt in the sea water probably has a lot to do with this as salt is an excellent disinfectant. Moreover the enormous volume of water in the sea together with the action of the tides contributes towards keeping sea water safe for swimming.
