At the end of a long day, all you want to do is ball up under the covers and call it a night. But as it turns out, sleeping in the fetal position could be zapping your confidence levels, according to new research from Harvard psychologist Amy Cuddy.
During a recent talk at the 92nd Street Y in New York, Cuddy cited her study about power positions and explained that sleeping with your knees clenched tight against your chest can actually cause you to wake up feeling super stressed out.
Here’s why: By sleeping all curled up, you’re actually sending a subtle signal to your brain that your body is under attack. But if you open up your posture in bed, you’ll see an immediate improvement in your daily confidence levels and happiness.
Worried that changing 30-plus years of sleeping habits sounds hard? Cuddy says that just waking up and stretching your body as wide as possible (arms over your head! toes pointed!) could make all the difference in your day.
So the next time your alarm goes off, hit snooze and stretch. Then tell the world: Hello, let’s do this.
