Elderly who go more often out into the sun have less chance of being depressed than elderly who stay indoors. This is the result of an investigation by the VU medical center among 1282 elderly.
Exposure of the skin to solar light increase the amount of vitamin D in the blood. This vitamin helps to reduce the chance of having a depression.
The elderly that took part in this research that suffered from depression had, on average, 14 percent less vitamin D in their blood than those without depression.
The head of this research says that walking, biking, doing groceries and other outdoor activities increases the exposure to sun light and can reduce the chance of getting depressed.
Of the people between the ages 55 and 85 almost 13 percent suffer from depression.
