Subject: How much sun is good for our health?
With cases of vitamin D deficiency on the rise, many are asking how much sun they should be getting in order to keep their levels up naturally. According to researchers, ten to twenty minutes is enough in the spring or summer, but nearly two hours is needed daily in the winter to meet our bodies’ needs. Then there is the question of the risk of skin cancers. Scientists have been trying to find an easy way to avoid these problems while allowing people to get the vitamin D they need. Unfortunately, this is a tricky problem.
- Researchers have estimated the duration of solar radiation exposure required in order to obtain the recommended doses of vitamin D.
- Every year, studies on the benefits of sunbathing in moderate doses are interspersed with those that confirm the risks of doing it excessively.
- While in spring and summer 10 to 20 minutes in the sun are enough, in the winter months almost two hours would be needed
"Although ultraviolet (UV) solar radiation contributes to the development of sun erythema, cancer and aging of the skin, it also reduces blood pressure."
