The Impact of Sunlight on Health
Studies have shown that exposure to sunlight correlates with better outcomes in terms of insulin resistance and cholesterol levels. This effect was observed even in regions with no possibility of vitamin D production during wintertime, indicating that sunlight has additional health benefits beyond vitamin D. Near infrared light may stimulate the mitochondria to produce antioxidants, such as melatonin, which can combat reactive oxygen species. Mitochondrial dysfunction, the benefits of near infrared light, and the interaction between the spike protein in COVID-19 and the ACE2 receptor highlight the potential role of sunlight in preventing redox stress in cells.
