We all love to exercise outdoors when the sun is shining. Exercise enhances oxygen flow to the skin, flushes out impurities from its surface, and promotes production of oil, your skin’s natural moisturizer. For good health we need natural sunlight to prevent depression in the winter and to activate vitamin D, which increases bone density. Some research even shows that sunlight has a protective effect against hypertension and some autoimmune diseases.
But there’s a downside for outdoor enthusiasts who spend many hours hiking, running, swimming, cycling, kayaking, canoeing and boating - unless they’re very careful they experience a higher incidence of skin damage and skin cancers.
