This nutrient contributes to the proper functioning of important systems, such as musculoskeletal  and immune systems , for example. Therefore, vitamin D at healthy levels in the body is essential.

Therefore, for the nutrient to be synthesized in the skin, just expose yourself for a few minutes to ultraviolet B (UVB) solar radiation , the main source of the vitamin for the body.

What is the best time to sunbathe?

In order for there to be an efficient synthesis of the nutrient, it is necessary to sunbathe when there is a higher concentration of UVB rays, which occurs between 10 am and 4 pm .

Sunbathing should be done between times with the highest peak of ultraviolet B (UVB) radiation.
However, doctors do not recommend long exposure at these times because of the risk of developing burns and eye damage. In addition, there is concern about cases of skin diseases, such as skin cancer.

How much sun to take?

The time varies according to the needs and specificities of each patient, that is, age , health , weight , skin color and even where the person lives .
However, doctors recommend sunbathing at least three times a week , without applying sunscreen to the exposed area of ​​the body, and as follows:

  • 15 to 20 minutes for those with white or sensitive skin ;
  • 30 to 40 minutes for those with dark skin ;
  • Up to 1 hour for those with black skin
