Bathe in morning sunlight to lose weight

Take morning sunlight not just to spruce up your vita-min D levels but manage weight too, research reveals.People who had most of their daily exposure to even moderately bright light in the morning had a signifi-cantly lower body mass index (BMI) than those who had most of their light exposure later in the day, the study has found.The timing, intensity and duration of your light expo-sure during the day is linked to your weight.“The earlier this light exposure occurred during the day, the lower individuals’ body mass index,” said Kathryn Reid, a research associate professor of neurol-ogy at Northwestern University’s Feinberg School of Medicine.The later the hour of moderately bright light exposure, the higher a person’s BMI, he added.The influence of morning light exposure on body weight was independent of an individual’s physical activity level, caloric intake, sleep timing, age or season.It accounted for about 20 percent of a person’s BMI.“Light is the most potent agent to synchronise your internal body clock that regulates circadian rhythms, which, in turn, also regulate energy balance,” senior author Phyllis C. Zee explained.The message is that you should get more bright light be-tween 8 a.m. and noon.About 20 to 30 minutes of morn-ing light is enough to affect BMI.
