News: Study Suggests Less Sleep Leads to Weight Increase
Be it beauty rest or power nap, everyone needs a little sleep sometimes. Scientists say it keeps memories sharp and prevents mood swings moods. But it turns out catching enough Zzs is about more than mental health. A recent study found children who don't get enough sleep are more likely to be overweight .
From A to Zzzzzzzzzzz – Analysis
In the study, researchers observed a group of 244 children between three and seven years old. At the end of four years, researchers found the children who slept more had a significantly lower risk of becoming overweight or obese. After further analyzing diet, exercise, and sleep habits over that period, researchers in the study found Body Mass Index decreased by 0.48 with each additional hour of sleep.
But the sleep-weight connection doesn’t end with childhood. Research suggests that amount of sleep affects adults’ weight, too . One study found women who slept five hours per night had an increased chance of gaining weight or becoming obese compared to those who slept seven hours per night. In some people, sleep deprivation might even be a risk factor for obesity . And it looks like we should avoid browsing Tastespotting after pulling an all-nighter: After a night of sleep loss, the brain region that controls appetite lights up more in response to images of food . (Try getting some rest and then tackling the temptation…)
Stop feeling guilty about hitting the snooze button. Studies show missing out on those Zzs can lead to weight gain.
