Many studies show that sleeping on your left side has unique health benefits. “Some health benefits can only be found when lying on your left side while you sleep.” This position supports the glymphatic system, which removes toxins from the brain. Research suggests that “people who sleep on their left side might be less likely to get brain diseases like Alzheimer’s.”
Sleeping this way also aids digestion. “When a person lies on their left side, gravity makes it easier for stomach enzymes and fluids to move through the body.” It can help with acid reflux and indigestion, making it ideal for those with sensitive digestion.
Another key advantage is heart health. “Sleeping on your left side keeps pressure off of important blood veins, which lowers blood pressure and improves blood flow.” This is especially beneficial for pregnant women and people with certain heart conditions.
Left-side sleeping can also reduce snoring and symptoms of sleep apnea. “The position helps the airways stay open,” improving sleep quality for both the sleeper and their partner.
Though adjusting may be difficult, “getting into the habit of sleeping on your left side every night” could improve brain function, digestion, heart health, and sleep quality.
