The human stomach can hold about 1.5 liters—3, tops. Pass 5 liters, and your gut will most certainly burst like a dollar store water balloon. To put this into perspective, 5 liters is about 11 pounds of pasta. By some estimates, enough to feed 60 people.

When you eat too fast, you swallow more air, which can cause bloating and gas. Slowing down to properly chew your food helps to break down larger particles of food into smaller ones, aiding digestion.

“Interestingly enough, you can rupture your stomach if you eat too much,” says Dr. Rachel Vreeman, co-author of “Don’t Cross Your Eyes They’ll Get Stuck That Way!” and assistant professor of pediatrics at Indiana University School of Medicine. “It is possible, but it’s very, very rare.”

Eliminating food and water intake for a significant period of time is also known as starvation. Your body can be subject to starvation after a day or two without food or water. At that time, the body starts functioning differently to reduce the amount of energy it burns. Eventually, starvation leads to death.

One notable drawback to sleeping on your side is that it can increase your risk of shoulder pain. Whether you’re on your left or right side, the corresponding shoulder can collapse into the mattress as well as up toward your neck, creating misalignment and pain the next morning.

Wearing socks in bed is the safest way to keep your feet warm overnight. Other methods such as rice socks, a hot water bottle, or a heating blanket may cause you to overheat or get burned. Sleep isn’t the only benefit to wearing socks at night. Read on to learn how this new habit could change your life.

Sleeping without a pillow can keep your head flat. This may reduce some stress on your neck and promote better alignment. But this doesn’t apply to other sleeping positions. If you sleep on your back or side, sleeping without a pillow may do more harm than good.

If you sleep on your back with your hands above your head, you’re bound to have shoulder pain. This position puts pressure on the nerves in your upper back and might leave you with numbness and tingling in your arms and hands. The good news with this position is that you’re already a back sleeper.

Sleeping with your bottom arm under your pillow or your top leg stretched out can lead straight to shoulder and neck pain. Side sleep can also put pressure on your stomach and lungs, but for the most part it’s a safe and popular choice.

Sleeping with your arms above your head can cause numbness by cutting off circulation to your hands. Avoid folding your arms under your pillow while you sleep. The weight of your head can put pressure on your wrists or elbows and compress a nerve.

Periodic Limb Movements of Sleep (PLMS) is when your legs or arms move when you’re asleep. It happens every 10 to 60 seconds and is out of your control. There are various ways this can happen such as flexing of the toe or foot, bending of the ankle or knee or twitching of the hip. This tends to occur over and over.

This is an involuntary startle response called the Moro reflex. Your baby does this reflexively in response to being startled. It’s something that newborn babies do and then stop doing within a couple of months.

(2006) found that participants awakened from REM sleep dreams are able to tickle themselves, which they explained by saying that “a deficit in self-monitoring and a confusion between self- and external-stimulation accompany REM dream formation” (Blagrove et al., 2006, p. 291).

Many people may have rumpled, worn-out bed sheets due to a condition called periodic limb movement disorder (PLMD), sometimes called periodic limb movements in sleep. During sleep, people with PLMD move their lower limbs, often their toes and ankles and sometimes knees and hips.

On Your Side with Legs Curled Up While not the worst position, sleeping on your side with your legs curled up does not provide the spine alignment you’d get from the recommended positions above. Sleeping with your legs curled up also doesn’t evenly distribute your weight throughout your body, which can lead to pain.
