There’s a direct link between your sleep, your spine, and your daily pain levels, according to a specialist in spine alignment. He explained that the way you sleep determines how well your spine rests and recovers. He identified two common positions—stomach and tight-fetal—that create a vicious cycle of pain by putting uneven pressure on the spine and straining nerves.
The specialist warned that this is not just a temporary issue. Continuing to sleep in a poor posture can lead to chronic back and neck pain and even a permanent posture imbalance. Your body needs to be in a neutral position to effectively repair muscles, ligaments, and joints overnight.
The first position to be avoided is sleeping on your stomach. The expert described this as “unnatural” because it forces you to twist your neck to one side, which strains muscles and compresses nerves. It also causes the lower back to arch excessively, putting stress on the lumbar region.
The second problematic posture is the tight fetal position. The expert noted that while it “feels super comfortable,” tucking your knees tightly to your chest “rounds the spine too much.” This C-shape over-stretches the back muscles, tightens the hip flexors, and restricts deep breathing, which can lead to decreased flexibility and chronic mid-back pain.
The best sleeping position, according to the specialist, is one that maintains the spine’s natural, neutral curve. He recommends lying on your back with a small pillow under your knees to support the lower back, or on your side with a supportive pillow between your legs to align the hips. These positions distribute weight evenly, prevent strain, and allow you to wake up refreshed.
