>North Korea is punishing women who try to beat the summer heat by wearing shorts
The current policy of sun avoidance is creating probable harm for the general population.
We are of the opinion that moderate sun exposure (less than the time required to burn) to the arms, shoulders, trunk, and legs should be sought rather than avoided.
The benefits of such exposure go beyond production of vitamin D and include other physiological responses to sunlight, still inadequately explored, including release of nitric oxide, production of beta-endorphin, and regulation of circadian rhythms—all important components of lifelong health and well-being.
