Who Is Most at Risk of Night Cramps?
Nighttime leg cramps—sudden, painful tightening of a muscle, usually in the calf or foot—can happen to anyone, but certain people are more likely to experience them.
- Older adults: Risk increases with age, particularly after 60.
- Pregnant women: Leg cramps are especially common during later pregnancy.
- People who are physically inactive: Long periods of sitting or limited movement may contribute.
- People who exercise intensely: Overworked or fatigued muscles can be more prone to cramping.
- People who stand for long periods: Jobs or activities involving prolonged standing can increase muscle fatigue.
- People with certain medical conditions: Diabetes, kidney disease, nerve problems, and some circulation disorders can be associated with cramps.
- People taking certain medications: Some medicines, including certain diuretics and cholesterol medications, may contribute in some individuals.
What may help
Gentle calf and hamstring stretching before bed, regular physical activity, adequate hydration, and avoiding prolonged inactivity may reduce episodes for some people.
If cramps are frequent, severe, getting worse, associated with swelling or weakness, or regularly disrupting sleep, speak with a healthcare professional. Don’t start potassium, magnesium, or other supplements solely for cramps without discussing it with a clinician.
