Sleeping position plays a bigger role in health than many people realize, and side sleeping—especially on the left side—can offer several benefits. When you sleep on your side, your spine tends to stay in a more natural alignment, which may reduce back discomfort compared to stomach sleeping. This position can also help reduce snoring because it keeps the airway more open. In addition, sleeping on the left side may support digestion, as gravity helps the stomach and intestines function more smoothly, potentially easing issues like heartburn or bloating. Some research also suggests that side sleeping could support brain waste-clearing processes during sleep and improve blood circulation, which is particularly important during pregnancy.

However, side sleeping is not perfect for everyone. Without the right mattress or pillow, it can cause pressure on the shoulders and hips or discomfort in the face and jaw. Adjusting your sleep setup—such as using supportive pillows, placing one between the knees, or choosing a mattress with balanced firmness—can make this position more comfortable. Ultimately, the best sleeping position is the one that feels natural and supports your body’s needs. Exploring small changes, like trying the left side or improving your sleep environment, can help you discover a healthier and more restful way to sleep.
