What Causes Muscle Cramps at Night?
Nighttime muscle cramps are typically caused by muscle fatigue, dehydration, or electrolyte imbalances. These painful contractions affect up to 60% of adults and most commonly occur in the calf muscles during sleep. Contributing factors include prolonged sitting or lying in one position, overuse of muscles during the day, and certain medications like diuretics or statins. Age increases risk, with adults over 50 experiencing cramps more frequently due to muscle mass loss and reduced activity levels. Pregnancy, diabetes, and kidney disease can also trigger nocturnal cramping by affecting fluid balance and nerve function.
