health benefits of sunlight
The health benefits of sunlight include increased metabolic rate, increased cardiovascular efficiency, increased metabolic rate and enhanced immune function. As we all know that sunlight exposure can stimulate the production of melatonin and vitamin D in our body. Vitamin D is an essential vitamin to our body and when inadequate, can lead to several serious diseases like arthritis. So the best way to avoid this is by taking a vitamin D supplement.
Besides vitamin D, the other important vitamin found in sunshine is Calcium. Vitamin D and Calcium are both needed by our body in a balanced level. The ultraviolet radiation from the sun also has some positive and harmful effects on our health, most importantly it is mutagens which is needed for the synthesis of certain vitamin D and is needed for our bones and teeth. A good dietary source of vitamin D can be provided by a supplement. Another great advantage of sun exposure is its relaxation and so it can reduce stress by helping us to feel refreshed and calm.
help improve the condition of their skin
Aside from the health benefits of sunlight, another good reason to expose your self to sunlight is to prevent certain types of skin cancers. This is especially true in the case of those who spend a lot of time indoors because in such cases, exposure to sunlight can actually help improve the condition of their skin and make it look younger and healthier. In fact, even cancer patients should take this opportunity to expose their bodies to sunlight because sunlight can be helpful in removing some types of cancer cells. Moreover, if you are a cancer patient, then you should also take this opportunity to change your lifestyle and cut down on the amount of time you spend indoors.
Another very common disease which can be prevented or improved by sunlight exposure is depression. This is because the ultraviolet rays of sunlight can actually stimulate the production of certain brain chemicals. For instance, an increase in serotonin can lead to reduced depression symptoms. Similarly, melatonin has been proven to be able to help alleviate depression symptoms. However, prolonged exposure to sunlight can actually result in increased production of melanin, which can potentially lead to darker skin; thus, increasing the possibility of skin cancer.
benefits of sunlight exposure
Finally, another group of health benefits of sunlight exposure includes cardiovascular disease, hypertension, osteoporosis and certain types of cancer. The increased vitamin D levels as a result of sunlight exposure can be one of the main reasons for this phenomenon. Thus, those who suffer from depression or heart disease should make sure they spend more time outdoors.
These are just a few of the diseases that can be prevented or improved by exposure to sunlight. Of course, it must be emphasized that sunlight does have its negative side effects too. For example, excessive exposure to the sun can lead to severe burnovers. In addition to that, prolonged exposure to the sun can lead to malignant melanoma; hence, the need for proper indoor tanning. Also, there is evidence that sunlight may increase the risk of certain types of cancers, such as colon cancer, rectal cancer and breast cancer.
