“Go out and go for a nice walk in the sun.” How many times our doctor, who has often become a friend because of his long lasting professional relationship, has given us this advice. But behind this simple and incisive phrase, not only the healthy idea of stretching your legs and distracting the mind is hidden. The equally fundamental concept is: sunbathe which fights depression. According to recent studies it seems that the vitamin D transmitted to our body by the sun’s rays also contributes to eradicating nervous exhaustion.
How this chemical process takes place
At the basis of these studies and these results, the vitamin D that would act on the Tph2 gene, transforming tryptophan into serotonin. Put simply, the more exposed we are to the sun, the less chance we have of being depressed. Vitamin D is in fact automatically produced with sun exposure, but without the tanning creams that otherwise block it! The advice of doctors is to simply expose your legs and arms to the sun, in good weather, for 20 minutes a day. Doing so would raise the minimum level of vitamin D in the blood, reaching the optimal threshold of 80ng / ml. According to the study, however, one in three inhabitants of the earth is very low: 25 ng / ml.
The direct relationship between depression and lack of vitamin D
The conclusion of the study focuses on the fact that there is a direct relationship between depressive states and vitamin D deficiency. A relationship so close to sentencing that 80% of patients suffering from nervous breakdown and bipolarism do not usually sunbathe. This is why the advice is useful: sunbathe to fight depression.
