Night cramps are sudden, painful muscle contractions—often in the calves, thighs, or feet—that strike during rest. While anyone can get them, some groups are more vulnerable:
Older adults: Nearly 1 in 3 over age 60 experience them, due to reduced elasticity, nerve function, and circulation.
Pregnant women: Extra weight, vein pressure, and hormonal changes disrupt electrolytes, making cramps common.
Athletes: Intense workouts and sweating deplete electrolytes, triggering spasms if recovery is lacking.
Sedentary people: Long hours sitting or standing reduce circulation, stiffening muscles.
Medical conditions: Diabetes, kidney disease, thyroid issues, and artery problems can all raise risk.
Medications: Diuretics, statins, and even birth control pills may contribute by altering circulation or electrolyte balance.
Night cramps are usually harmless but can signal an underlying issue—especially if frequent or linked to new medication.
