If you’re like most people, you probably don’t give much thought to how you sleep at night. As long as you’re getting those precious zzz’s, what does it matter if you’re curled up on your side, sprawled out on your back, or face-down on your stomach?

Well, it turns out the position you choose to rest your head could have a bigger impact on your health than you realize. In fact, different sleeping positions can lead to vastly different results in the body – for better or for worse.
While people should ultimately sleep in whatever way feels most comfortable, understanding the potential benefits and drawbacks of each position can be eye-opening. And one sleep style in particular – sleeping on your left side – has some pretty remarkable advantages that may just have you rethinking your nightly routine.
The Benefits of Sleeping on Your Left Side
Reduce back pain – Sleeping on the stomach could pressure the spine and cause aching. Side sleeping keeps the spine in a naturally straight position and reduces the pressure in the lower back.
Reduce snoring – Sleeping on the back causes the tongue and soft palate to slide backward and partially cover the airway, causing increased snoring. It’s also a common occurrence for people with sleep apnea. But side-sleeping keeps the tongue forward and the airway clear.
Improve digestion – Sleeping on the left side, in particular, could ease some gastrointestinal symptoms like bloating, constipation, and heartburn. The stomach is on the left side of the body, so lying on that side allows gravity to aid the digestion process.
It may help with brain health – Many people are unaware that the brain eliminates waste during slumber. Studies indicate that side sleeping helps the brain clear metabolic waste more effectively by supporting the glymphatic system, which is similar to our lymphatic system, but in our central nervous system. This may help reduce the risk of Alzheimer’s Parkinson’s, and other brain diseases, according to animal studies. More research is needed on humans to expand on these concepts further.
Improves blood flow – Good circulation is crucial during pregnancy to allow blood to flow to the placenta. This is why it’s recommended that expecting women sleep in this position.
How to Train Yourself to Sleep on Your Side
- Choose a good pillow and mattress
Find a pillow well-suited to your collarbone structure.
Ensure the pillow is firm enough to support the neck.
Mattresses must often be softer to prevent pressure from building in the shoulders and hips.
- Use pillows as barriers and supports
Put a pillow between your knees to support your hips and lower back
You can also hug a pillow to comfortably rest your upper arm.
Invest in body pillows to maintain your position.
Sew a tennis ball onto the back of a shirt to prevent yourself from rolling over.
- Sleep on the couch at first
Couches are often narrow and only have room for side sleeping anyway.
Disadvantages of Sleeping on Your Side

Although this position could provide many benefits, it’s not for everyone, especially those who use mattresses and pillows that make side sleeping uncomfortable. These disadvantages include:
Pain in the shoulders and hips
Side sleeping on too-firm mattresses could increase pressure on the shoulders, hips, and knees. However, too-soft mattresses could cause the spine to go out of alignment and also cause pain.
Pressure in the face
People with sinus congestion and glaucoma may experience painful or uncomfortable pressure in their faces when they lie on their sides. Additionally, it could worsen a tight or stiff jaw.

Ultimately, people should sleep in any way they feel most comfortable. But it’s important to consider how your sleep position could affect your body, for better or worse. You could also begin your nights on your left side and allow your body to assume whatever position it prefers. Also, sleeping on the right side also comes with benefits, so don’t stress about trying to retrain yourself if it’s not coming easily. Similarly, there are pros and cons to sleeping on the back and stomach.

Tips:
- Place a pillow under your knees to support the spine and lower back.
- Spread the legs and arms out to reduce pressure on the joints.
- Choose a pillow that offers good support for the neck, and avoid the ones that tilt your chin toward your chest.
- Elevate the head with extra pillows or a wedge pillow to help reduce heartburn, headaches, and sinus buildups.
Sleeping on your stomach

Unfortunately for those who enjoy this position, experts warn against it. “If you are sleeping on your stomach and notice you are suffering back pain, there probably is a reason,” says Bill Fish, a certified sleep science coach. “Since the majority of the weight of the human body is around your center, that core pushes into the sleep surface further and basically puts strain on your spine in the wrong direction, causing back and neck pain.”
Still, here are some tips for those who can’t switch to their side:
- Use a flat pillow or none at all.
- Don’t tuck your arms under your pillow or head, since this could cause arm numbness or shoulder joint pain.
- Alternate the sides of your head to avoid neck pain.
- Don’t lift your leg to one side with a bent knee since this could worsen back issues.
Conclusion
At the end of the day, the “best” sleeping position is the one that leaves you feeling rested, refreshed, and free of aches and pains. But if you’re experiencing issues like back pain, snoring, digestive troubles, or brain fog, it may be worth giving left-side sleeping a try.
With a little experimentation and the right adjustments to your sleep setup, you could unlock a whole host of surprising health benefits. Who knows – it may just change the way you think about getting a good night’s rest.
