This author is dead wrong about prone sleeping. As we have learned from the Covid pandemic, prone sleeping actually improves airway gas exchange and oxygenation of tissues. Additionally, because of the forward migration of the mandible, prone sleeping is beneficial in the treatment of sleep apnea. As a dental student, this author should also understand that forward migration of the mandible reduces bruxism - a major contributor to dental problems, particularly TMJ. As regards the effect of prone sleeping on the neck and low back, there are a number of new mattress and pillow constructs that address the biomechanics of that issue. I am a board-certified pulmonologist with a sub-specialty in sleep medicine, and yes that are many professionals, like myself, who recommend prone sleeping.
