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.

Recognize her? Better sit before you learn her true identity…
Joan van Ark was born on June 16, 1943, in New York City, New York. Her parents were not connected to the film industry.
When Joan was a teenager acting in Denver, she met actress Julie Harris, and their lives would never be the same.
Julie pushed her to go to the highly regarded Yale Drama School and gain admission using a scholarship she had also set up.

This made Joan Van Ark the second-ever woman to enroll at the Drama School
She [Harris] wrote to the dean and asked him to meet me. “Long story short, my parents drove me to New Haven, Connecticut, to meet the dean, who gave me a scholarship,” Joan recalled.” It was meant to be.” Joan went on to perform in the theatre for a few years, but her real passion was in Television.
Temperature’s Rising, Spider-Woman, and Days of Our Lives

Joan achieved enormous renown as a result of her roles in Temperature’s Rising, Spider-Woman, Days of Our Lives, and even one Bonanza episode. But her role as Valene Ewing on Dallas in 1978 was where she first achieved great popularity. She ended up playing the most important role she has ever had.
Because of how popular the show was, Joan appeared on its spin-off, Knots Landing. a program that was actually written prior to Dallas. Dallas was initially chosen by the producers because it was the best option for portraying affluent households at the time. Joan was then forced to play the same part in Dallas instead of joining the Knots Landing cast.
13 Seasons of Knots Landing ensued for Joan Van Ark

The person who actually convinced Joan to accept the part while already working on two other projects was her husband, renowned newscaster John Marshall. There was a moment when Val Ewing’s mother was scheduled to make her television debut. Surprise, surprise—Julie Harris was chosen for the position. The person who mattered the most to her in all the world was this.
“When the producers told me they had finally last someone to play my mother, I held my breath,” she recalled in a 1984 interview with Florida Today. “I thought, ‘Oh my God, are they going to say Phyllis Diller or Zsa Zsa Gabor, or who?’ Then they said it was Julie Harris, and I went right through the roof. I couldn’t believe they had picked her to be my mother. They didn’t even know we were friends.”
327 Episodes later, Joan Van Ark was ready for new ventures

13 Seasons and 327 episodes later, Joan left a season before the show saw its final season air. She knew many blamed her leaving on the cancellation of the show, but she was ready for new adventures. “I have loved more than life the 13 years I’ve had on that show,” she said. “[Knots Landing creator] David Jacobs is a great influence on my life, has taught me so much about so many things.”
“Ted [Shackelford] is the other half of every breath I take on the show, and personally, he’s a large part of my heart. The people are my family–we have shared marriages, deaths, and divorces. It’s far more difficult to leave than I thought.” Joan thereafter appeared on The Young and The Restless as Gloria Fisher.

In high school, John Marshall first met Joan, and the two quickly got married. They have a lovely daughter named Vanessa Marshall who works in the entertainment industry at the moment. After 56 years of marriage, the pair is still very much in love and leads extremely private lives away from the spotlight.
78 years old with a net worth of $10 million

At 78 years old, Joan has amassed a $10 million net worth and is still as gorgeous as ever when seen out and about in Los Angeles. She was last seen three years ago and was just seen paying for parking at a meter while wearing workout clothes and a ponytail.
She co-starred in the 2017 television film Psycho Wedding Crasher, which was her most recent and final appearance on screen.
Joan Van Ark, who has worked in the film industry for the past 50 years, has joined The Actor’s Studio as a life member. What an icon!
