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.
If you often wake up with back pain, acid reflux, or poor circulation, making the switch to left-side sleeping might improve your overall well-being. However, comfort is key, so if this position doesn’t feel right, listen to your body and find what works best for you.

I Was the Only One Who Went to My Grandma’s Birthday Brunch — After Seeing Her Tears, I Taught My Family a Lesson

My story begins badly but ends on a positive note. It’s about my Gran-Gran, the sweetest lady alive, who raised me and my brothers during our parents’ divorce. Ahead of her 83rd birthday, she surprised us by organizing a brunch at her place, despite her deteriorating health, making her own bread and pastries, and sending handwritten invites.
On her birthday, I arrived 10 minutes late to find her cleaning up alone. She admitted, “Sany, you aren’t too late, no one bothered showing up on my birthday. But it’s okay, sweetheart. I know everyone is busy.” My heart broke. Everyone had promised to be there, but none showed up. I hugged her and decided to take action.v
I lied to my family, saying Gran-Gran had fallen and was in the hospital, convincing them to send money for hospital bills. I collected a significant amount and used it to book a trip for Gran-Gran and me to a beach resort she’d always wanted to visit. We spent a week enjoying the sun, the sea, and each other’s company. I shared the trip images on social media, tagging all our family members.
When we returned, Gran-Gran was glowing. “Thank you for this, darling. It’s been the best week of my life,” she said. From that day on, my family never missed another event. They showed up for every birthday, holiday, and Sunday dinner. Every time I saw Gran-Gran’s happy face, I knew it had all been worth it. Do you think I overreacted and took things too far?
