This is what sleeping on the left side does for our brain, stomach & glymphatic health

Most of us don’t think twice about how we sleep. We just curl up in whatever position feels most comfortable and drift off. But did you know that your sleeping position can affect your brain function, digestion, and overall health? Studies suggest that sleeping on your left side offers surprising benefits, from improving digestion to enhancing your brain’s natural detox system.

If you’ve never considered changing your sleep posture, now might be the time! Let’s explore the science behind left-side sleeping and how it can positively impact your body.

The Surprising Benefits of Sleeping on Your Left Side

Sleeping on your left side isn’t just about comfort—it can actually improve several bodily functions. Here are the top benefits of making the switch.

Supports a Healthier Spine & Reduces Back Pain

Ever wake up with an aching back? Sleeping on your stomach or even your back can put unnecessary strain on your spine. When you sleep on your left side, your spine stays in a more natural alignment, reducing tension in your lower back. If you suffer from chronic back pain, switching to your left side could be a game-changer.

Helps Reduce Snoring & Sleep Apnea Symptoms

Snoring happens when the airway is partially blocked. When you sleep on your back, your tongue and soft palate fall backward, making snoring worse. Side sleeping, especially on the left side, keeps your airway open, reducing both snoring and symptoms of sleep apnea. If your partner often complains about your snoring, this might be the easiest fix.

Aids Digestion & Reduces Acid Reflux

Sleeping on your left side can actually help your digestive system. Since your stomach is naturally positioned on the left side of your body, lying on that side allows gravity to aid digestion. This can help prevent acid reflux and heartburn, improve digestion by helping food move smoothly through the intestines, and reduce bloating and constipation.

Boosts Brain Health Through the Glymphatic System

Did you know your brain has a built-in cleaning system? It’s called the glymphatic system, and it works mainly while you sleep. This system helps flush out toxins and waste that accumulate in the brain during the day.

Research suggests that side sleeping improves glymphatic drainage, meaning it can help remove harmful substances linked to neurological diseases like Alzheimer’s and Parkinson’s. In short, sleeping on your left side may support better brain health and reduce the risk of cognitive decline.

Enhances Circulation & Heart Health

Sleeping on your left side also helps your heart work more efficiently. Because your aorta (the main artery) curves to the left, sleeping on this side reduces pressure on the heart, making it easier for blood to flow.

For pregnant women, doctors highly recommend sleeping on the left side to improve circulation to both the mother and the baby.

How to Train Yourself to Sleep on Your Left Side

If you’re a back or stomach sleeper, you might be wondering how do I train myself to sleep on my left side? Here are some helpful tips.

Use the Right Pillow & Mattress

A firm mattress and a good pillow will support your neck and keep your spine aligned while you sleep. A memory foam pillow that conforms to your head and neck is ideal.

Use a Pillow as a Barrier

Placing a pillow behind your back can prevent you from rolling onto your back while you sleep. If you want extra support, try hugging a pillow to keep your upper body stable.

Put a Pillow Between Your Knees

If you experience hip or knee discomfort, a small pillow between your knees can help reduce strain on your joints and keep your spine aligned.

Wear a Sleep Shirt with a Tennis Ball

This is an old trick, but it works. Sewing a tennis ball into the back of your sleep shirt makes it uncomfortable to roll onto your back, helping you stay on your side.

Try Sleeping on a Couch Temporarily

If you’re struggling to train yourself, sleeping on a narrow couch for a few nights might help, as it naturally limits movement.

The Downsides of Side Sleeping

While sleeping on your left side has numerous benefits, it’s not perfect for everyone. Here are a few potential drawbacks.

Shoulder & Hip Discomfort

If you sleep on a too-firm mattress, your shoulder and hip may feel sore due to added pressure. The solution is a softer mattress or a memory foam topper that can help cushion these areas.

Facial Wrinkles & Puffiness

Pressing your face into a pillow every night can cause wrinkles over time. If this concerns you, try using a silk pillowcase to reduce friction on your skin.

Jaw Stiffness

If you suffer from TMJ (jaw pain), sleeping on one side might add pressure to your jaw. Switching sides occasionally or using a softer pillow can help alleviate this issue.

Final Thoughts: Should You Switch to Sleeping on Your Left Side?

Your sleep position plays a bigger role in your health than you might realize. While everyone has their own preferred sleeping posture, sleeping on your left side offers significant benefits for your brain, digestion, heart, and spine.
