Sleep quality is a primary marker of physiological recovery, yet it is deeply dependent on the musculoskeletal and postural systems. The sources explain that postural distortions, particularly forward head posture, create mechanical disadvantages for the airway. When we lie down, decreased muscle tone can cause these misalignments to collapse the airway, leading to drops in oxygen saturation. Each oxygen dip triggers a reflexive heart rate spike, causing "micro-arousals" that prevent the patient from entering restorative deep sleep stages like REM and delta.

Chiropractors play a vital role in improving sleep quality by addressing these structural contributors. The connection extends from the feet to the spine: issues like asymmetrical overpronation or pelvic rotation can create a "tug-of-war" between the psoas and the diaphragm, restricting normal breathing mechanics that persist during sleep. By restoring alignment and stabilizing the body's foundation—potentially through custom orthotics or cervical pillows—chiropractic care helps shift the nervous system from a state of vigilance to one of repair. Ultimately, correcting mechanical distortions allows for deeper, more stable breathing, which naturally improves sleep quality and supports overall musculoskeletal health.
