A massive Swedish study followed 30,000 women for over 20 years and found that those who actively sought sun exposure had dramatically lower death rates from cancer, heart disease, and all causes. The shocking part? Sun avoiders had roughly double the overall mortality. Even heavy smokers who got plenty of sun had similar death rates to non-smokers who avoided it. Sunlight appears to extend life through vitamin D, nitric oxide, and immune support – yet we're still told to hide from it. Are you getting enough sun?
