Usually, the brightness of the sun is associated with a call to caution. But sunlight also triggers a steady stream of chemical reactions, which can act as a miracle cure for mental health—all winter long.
That your mood in the winter is linked to how much sun you are exposed to in the summer was only scientifically confirmed in the 2000s.
The relationship is complex and partially unexplored, but two of the main characters are a hormone and a vitamin that work together and separately to improve mood during the winter.
The light emitted by the burning ball of gas around which our planet orbits has a direct effect on sleep, memory, attention and mood, as it stimulates the hormone serotonin in the brain.
At the same time, sunlight stimulates vitamin D in the skin – and this combination could be the key to how to avoid suffering from winter depression.
The body itself produces miracle vitamins
studies He also showed that a lack of vitamin D can lead to depression.
When the skin is exposed to sunlight, it itself forms vitamin D. The light consists of UVB rays, which penetrate the skin and break down a fat called 7-dehydrocholesterol, which is thus converted into a type of vitamin D, D3.
