Every morning, the same ritual: tingling in the fingers, stiff shoulders, the need to shake your arms to regain feeling. You chalk it up to a bad night's sleep, but what if your sleeping position is the real culprit? This instinctive posture, arms curled up against your chest like a tyrannosaurus, threatens your nerves and your daily comfort.<\/p>\n
Known online as the "T. rex position," it compresses the nerves in the elbows and wrists. A study published in the Journal of Orthopaedic & Sports Physical Therapy<\/a> shows that prolonged elbow flexion during sleep significantly increases intra-nerve pressure in the ulnar canal, causing paresthesia and pain in 25% of side sleepers. Repeated night after night, it can worsen shoulder tension and cause nerve irritation similar to carpal tunnel syndrome. <\/p>\n\n
