Sleep-Related Leg Cramps: A Comprehensive Guide
Leg cramps, often referred to as “charley horses,” are painful, involuntary muscle contractions that can disrupt your sleep, exercise routine, and overall quality of life. These cramps can last from several seconds to a few minutes and are common among adults, especially those over 60, women, and people assigned female at birth (AFAB). Approximately 60% of adults and 40% of children and teenagers experience them at night.
Overview
Leg Cramps at Night
Leg cramps at night are sudden, intense muscle pains typically affecting the calf, foot, or thigh. They can cause muscle spasms and, while generally harmless, they are quite painful and can significantly impact sleep quality.
Duration
These cramps can last from several seconds to several minutes, leaving the affected muscle sore for hours afterward.
Who Gets Them?
Leg cramps become more common with age, particularly in individuals over 60. They also occur more frequently in women and AFAB individuals. Nighttime leg cramps are especially prevalent in older adults and during pregnancy.
