You turn off the lights and get yourself ready to snooze. Are you on your back, side, or stomach? Though there is no strong science connecting your sleep position to things like back pain, snoring, personality, and how often you wake up during the night, here are some interesting associations that have been noted.

On Your Belly

Are you a tummy sleeper? If so, do you have problems sleeping? Your slumber pose may not be helping. You’re more likely to be restless and toss and turn to get comfortable when you sleep on your belly. It can strain your neck and your lower back, too. If this is how you like to sleep, you may want to use a very soft pillow or none at all to keep your neck comfortable.

Belly Position: Freefall

About 7% of the population sleeps this way. You lie on your belly with your arms around a pillow and your head turned sideways. If this is your favorite sleep position, some research suggests you may be more likely to speak your mind and be sociable and outgoing. You also may not be very open to criticism.

Back Sleeping

This position can cause low back pain for some people. And if you already have that, it can make it worse. If you snore or have sleep apnea, it can make those bigger problems, too. If you have one of these issues and can’t get comfortable another way, talk to your doctor about what might help.

Back Position: Soldier

This position is favored by about 8% of the population. You sleep with your arms down and close to your body. Some research suggests you may be more likely to be quiet and keep to yourself. You also may expect a lot from yourself and from others.

Back Position: Starfish

Only about 5% of people sleep this way. You lie on your back with your arms up near your head. According to some studies, you may be more likely to be a good listener and not want to be the center of attention.

Side Sleeping

There are many ways to sleep on your side, but the most comfortable is with your knees bent slightly toward your chest — the fetal position.

Side Position: Fetal

More than 40% of people sleep in this curled-up side-sleeping position. It’s the most common position for women — they’re twice as likely as men to sleep like this. Some research suggests you may be more likely to be warm, friendly, and sensitive, but you also may have a protective shell around you.

Side Position: Log

This is when you sleep on your side with both arms down. About 15% of people “sleep like a log.” Some research says you may tend to be social, easygoing, and trusting. Source: Webmd.com
