This news might have you beaming: a study from Northwestern University suggests that a dose of bright sunlight could help you stay slim. People exposed to the most morning and early-afternoon rays had lower BMIs than those who took in less. Morning light may send signals to your brain that increase alertness and production of metabolism-regulating hormones, says study author Dr Phyllis Zee. She suggests sitting at a window or walking during your lunch break. Wear sunglasses but avoid amber or brown lenses, which block circadian-regulating blue light.
Sunlight has also been suggested to Increase Your Muscle Size.
