Sunbathing regularly has a positive influence on the brain, because it stimulates the generation of vitamin D by the body. This was discovered by British scientists.
Researchers at the University of Manchester tested about 3000 men in the ages of 40 till 79 and measured how fast and careful their brains could process and retain information. The amount of vitamin D in the blood was also measured.
The research showed that the men who had the highest level of vitamin D in their blood delivered the best test results in the brain test.
The results were published in the scientific magazine Journal of Neurology, Neurosurgery and Psychiatry.
The human body produces vitamin D when the skin is exposed to sunlight. But also eating certain kinds of food, like fish for example, can stimulate the body to produce vitamin D. According to the scientists their study shows that especially elderly people could benefit from sun exposure or following a special diet.
Interestingly the connection between vitamin D and faster information processing by the brain is especially evident in men above 60. The biological cause for this phenomenon is still unclear.
The researchers warn however that the sunbathing should not be exajurated, because it might not only keep your brain in shape, but it also increases your chance of skin cancer.
