Side sleeping is a common position with notable health benefits. It can reduce back pain by keeping the spine aligned and lessen snoring by keeping airways clear. This position also improves digestion, particularly on the left side, as gravity aids the stomach’s processes. Additionally, side sleeping supports brain health by enhancing waste clearance, potentially lowering the risk of conditions like Alzheimer’s. It also promotes circulation, which is vital during pregnancy.

However, side sleeping isn’t perfect. It may cause shoulder and hip pain on overly firm mattresses or misalignment on softer ones. People with sinus issues or glaucoma may experience facial pressure, and jaw discomfort could worsen.

To maximize comfort, use a supportive pillow and mattress suited to your body. Pillows between the knees or for hugging can provide extra alignment, while body pillows help maintain position. A narrow couch can also encourage side sleeping naturally.
