In terms of time, doctor Jiang Kunjun pointed out that you only need to bask in the sun for 10 to 15 minutes. Sunbathing for 30 minutes will not be more concentrated than sunbathing for 15 minutes. The key is to choose the right time to bask in the sun.

The choice is very simple, it depends on replenishing the vitamins in the blood. It will be good if the D concentration has increased.
