How does sleeping with an elevated head affect the body?
When a person sleeps with an elevated head, it reduces the pressure in the head and neck's blood vessels, neurologist Dr Chandril Chugh stated, adding if it's too steep, it may "limit blood flow, causing...stiffness". This position benefits those with acid reflux, sleep apnea, sinus congestion, etc, as per experts. Dr Chugh, however, advised caution for people with back issues.
