But even during the spring-summer the situation does not improve much because, in addition to spending our lives indoors, when we expose ourselves to the sun, we sprinkle ourselves with sun creams that inhibit the absorption of almost all of the UV rays, believing, without reason , that the sun is harmful and represents the cause of melanoma, a fact that has no valid scientific support except in particularly predisposed subjects.
To remedy this remote possibility, however, there is a reasonable middle ground: expose yourself to the sun without protection for at least 20-30 minutes and then sprinkle quietly with creams and sunscreens. In this way we are sure that we have made an adequate daily supply of vitamin D but we will not expose ourselves to other, albeit hypothetical, risk factors.
Some researchers claim that the autumn-winter season, with its lack of sunlight, is the most important cause of seasonal diseases, linked to a lower sun exposure, especially in the northern regions and countries.
