Sunbathing is an integral and much loved part of most people’s holiday but recent
reports of over exposure to the sun causing skin cancer have
made many people wary of spending too much time in the sun. However
paradoxically the over use of sun screens can actually have health problems in itself
and under exposure to the sun can also be detrimental to our well being.
Too much high factor sun block can delay sunburn, which is of course an important reminder that
you have had too much sun, and in addition it can block the
bodies manufacture of vitamin D which in itself helps to protect
us from skin, breast and prostate cancer and is invaluable for boosting the immune
system in general. Vitamin D also offers us protection against osteoporosis
and sunlight can, believe it or not, play a part in lowering cholesterol levels and blood pressure.
Another danger with using sunscreen is due to the fact that they tend
to only screen the UVB rays which cause the sunburn and not the UVA
ones which actually inflict the cancer causing damage. Therefore people
mistakenly feel protected but in fact end up putting themselves at great risk
as is evidenced by the continued growth in malignant melanoma, skin
cancer, despite increased use of sunblock creams
It is important therefore that we shouldn’t all get a sun phobia as it does plays a vital
part in both our physical and mental welfare and a certain amount of time
spent in the sun will do us a lot more good than harm.
As mentioned sunlight is important for the production of vitamin D, it also
plays a role in the production of melatonin which controls our sleep
patterns amongst other things, so a lack of sunlight can lead to insomnia.
Melatonin also plays an important part in building a healthy immune system
and can help protect against cancer.Serotonin, the good mood hormone, is
likewise produced in the body in the presence of sunlight.
