Sleep to stay thin and be happy

Scientists have repeatedly shown that there’s a link between sleep deprivation and obesity. When you cut back on sleep, your body produces less leptin, a hormone that helps regulate appetite and metabolism, and more ghrelin, a hormone that stimulates hunger. Scientists studied how sleep affects activity in the brain’s frontal lobe, which controls behavior, and found that lack of sleep impairs our capacity to evaluate which foods are best for us.

But weight control isn’t the only reason to get a full night’s rest. Researchers have consistently found that getting enough sleep is correlated with feeling happier. A study determined that earning $60,000 more a year has less effect on daily happiness than getting just one additional hour of sleep each night. Learn more here.
