Sleep is one of the pillars of good health, but it gets short shrift. People spend money on mattresses, sleep apps and routines but overlook one of the most important factors for quality sleep, the pillow. Using the wrong pillow can cause neck pain, disrupt your posture, rob you of sleep and even lead to chronic musculoskeletal problems.
Side sleeping, according to doctors and sleep experts, is the most common sleeping position and the one we should be using. It has a few health benefits, including supporting your breathing, improving digestion and reducing the chances of snoring. This is but one of the many advantages, all of which only apply when body support is correct.
This is where side sleeping pillows come into play. Body pillows are designed to keep the natural alignment of the body while you’re lying on one side. They help keep the head, neck and spine in a neutral alignment to prevent strain and discomfort.
There is some research demonstrating that good pillow support can result in improved sleep and decreased neck pain. The rise of sleep ergonomics means side sleeping pillows are becoming an essential part of contemporary slumber setups.[1]
