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.

Some research even shows that sunlight has a protective effect against hypertension and some autoimmune diseases.
