Recent studies in the United States and Australia suggest that Vitamin D is a key nutrition that helps in making the immune system strong.
An Australian study reveals that people who have spent more time in the sun and those with higher vitamin D levels may be less likely to develop multiple sclerosis.
Another study conducted by the United States Heart Research Center observed that men who consume the recommended amount of vitamin D are somewhat less likely to suffer a heart attack or stroke than those with low vitamin D.
According to the Australian research, people living close to equator were reported to suffer less from multiple sclerosis. The reason for the lower number of disease spread is more exposure to sunlight, thus higher levels of vitamin D.
Meanwhile, researchers in Australia are busy finding the exact number of hours or exact amount of UV dose that is required by a normal human body to help avoid dangerous diseases.
On the other hand, the survey conducted in the United States found that men who got at least 600 IU of Vitamin D per day were 16 percent less likely to develop heart problems or stroke than men who got less than 100 IUD per day.
Lead research Qi Sun at the Harvard School of Public Health writes, "These observations suggest that a higher intake of vitamin D is associated with a lower risk of cardiovascular disease in men but not in women.”
More researchers in the United States opine that taking vitamin D may help protect women who have already had non-melanoma skin cancers against a much deadlier form of the disease. But, researchers also caution that the results need to be further confirmed by running some more experiments, as the melanoma is the most dangerous type of skin cancer. However, the main message which was extracted from this research was that sun exposure is mandatory for all human beings.
Health expert Dr. Lucas said, "small amounts of sun exposure... occurring frequently, are probably optimal both for maintaining vitamin D levels and for other health effects."
Since sun exposure is associated with a higher risk of skin cancer, more time outside is not always better. Nor do the results mean that everybody should load up on vitamin D. Therefore, blind exposure to sun is also not advised in the research. The ongoing research will produce important results in a short time regarding body’s exposure to sun.
