The BDNF Files | How summer & sunlight make you smarter and happier
While some sun-phobic dermatologists would prefer to lock humanity up in their homes when the sun is out, an overwhelming body of scientific studies show that normal exposure to sunlight is healthy. It is not without reason that exposure to sunlight extends life span. A Dutch study suggests that sunlight also protects against depression, anxiety and dementia. Sunlight increases the concentration of BDNF in the blood.
Several times during a year, the researchers took blood samples from the study participants in which they measured the concentration of brain-derived neurotrophic factor [BDNF].
BDNF is a hormone that keeps brain cells healthy and stimulates the formation of new connections between them. BDNF plays an important role in cognitive abilities and learning processes. In neurological disorders such as Alzheimer's disease, Parkinson's disease and Huntington's disease, as well as depression and anxiety, the activity of BDNF is reduced.
