This Is What Your Sleep Position Reveals About Your Personality

But which side?

According to a survey conducted in the UK by mattress manufacturer, Sealy, left-side sleeping is favored by those who work in marketing and advertising, those between the ages of 45 and 54, and those who are degree-educated, whereas right-side sleeping is favored by those who work in transport and manufacturing, those between the ages of 35 and 44, and those who smoke and love caffeine (we’re talking 10 caffeinated drinks a day, minimum).

As for the relative benefits of each:

  • Left-side sleeping may improve heartburn symptoms, according to Michael Breus, MD, an Advisory Board Member to SleepScore Labs. “The reason for this is because when you sleep on your right side, the lower esophageal sphincter relaxes, allowing stomach acid to leak out, which can result in irritation,” he explains. In addition, during pregnancy, according to the American Pregnancy Association, “sleeping on your left side will increase the amount of blood and nutrients that reach the placenta and your baby.”
  • Right-side sleeping may be better for your heart, according to Nazma Parveen, MBBS, for the simple reason that it does not add any gravitational pressure to the heart.

Tummy time

Sleeping face down is far less popular than side-sleeping, and experts recommend against it for women who are pregnant or have large breasts, and it’s a bad idea for anyone with neck injuries, back problems, or who own very soft mattresses. That’s because stomach-sleeping encourages back-arching, explains mattress designer, Flother.

Stomach-sleeping also means that your neck is going to be stuck in one position for an extended period of time, says Dr. Greuner. So it’s no surprise if you wake up to neck pain and experience muscle spasms and chronic pain.

According to Sealy’s research, stomach-sleepers tend to work in agriculture, to be between the ages of 45 and 54, and to be heavy drinkers (averaging the equivalent of seven to 10 units of alcohol a day—that’s about two to three beers or glasses of wine a day). According to Dr. Idzikowski, however, if your sleeping position of choice is face-down with your head turned to one side and your pillow grasped between your arms, you have a tendency to be gregarious, and even at times brash—but you really don’t like to be criticized. And you do your best to avoid extreme situations.

However, if you’re a new parent, avoid letting your child sleep face down. There’s a reason why newborn stomach-sleeping the worst possible choice.

On the back track?

People who sleep flat on their back tend to work in transport and logistics, according to Sealy’s research. And they’re also most likely to wake up feeling “refreshed.” But maybe that’s because back-sleepers tend to be a young group, in general, with most of them being between the ages of 25 and 34. which is the best age for sleeping soundly through the night.

In addition, snoring is associated with back-sleeping, according to Dr. Greuner, which means that although you may be waking up refreshed, your partner won’t be. SleepScore’s Dr. Breus explains why this is: “When you’re lying on your back, your throat is more narrow, making snoring louder and more frequent.” This can be alleviated by sleeping on your side, Dr. Breus advises, which may seem difficult if it’s not your preference, although there are wearable products on the market that can help. “You can also put a hard object, like a football, in a kid’s backpack and wear that to bed so if you shift onto your back, your body will adjust itself,” he adds.

A recent study published in the Journal of Physiology also indicates that back-sleeping is bad for unborn babies at the tail end of pregnancy, raising the risk of stillbirth.
