Sleep Position Identified as Main Cause of Night Leg Cramps
Doctors report that nighttime leg cramps affecting many sleepers are rarely a sign of serious illness, and are mostly linked to sleeping posture.
Cause Details
Dr. Mohamed Imam, a physiatrist at Johns Hopkins Hospital, explained that sleeping with the toes pointed down forces the calf muscle into its shortest, most contracted position, increasing the risk of nocturnal cramps.
During the day, regular movement and walking keep muscles in a balanced stretch‑contraction cycle, reducing cramp occurrence.
Medical Background
Studies show dehydration or nutrient deficiencies are not the primary triggers, although they can aggravate symptoms for some individuals.
Practical advice includes avoiding the downward toe position and using a pillow to support the legs, lessening muscle strain during sleep.
