Too Little Sleep, Too Much Weight?
It might seem like people
who sleep the fewest hours would be burning more calories. But a recent study
showed that people who got less than 4 hours of sleep per night were 73 percent
more likely to be obese than people who got 7 to 9 hours. And people who had an
average of 5 hours of sleep per night had a 50 percent greater risk.
The study followed 18,000
adults who took part in the federal government’s National Health and Nutrition
The catch seems to be that
while people are staying awake for longer hours, they are also more likely to be
eating. When you don’t get enough sleep, your body has lower levels of a protein
called leptin, which helps suppress your appetite. Additionally, the sleepier
you are, the less sound your decision-making ability is, so you’re more likely
to eat things you really shouldn’t be eating.
So the message is really
simple here: get to bed before the urge for a cheeseburger hits in the wee hours
of the morning.
