Night cramps (often called nocturnal leg cramps) can happen to anyone, but some people are more likely to experience them. Those at higher risk include:
- Older adults: Risk increases with age, especially after 50, partly because of changes in muscles, nerves, and circulation.
- Pregnant people: Leg cramps are common during pregnancy, especially in later months.
- People who are physically active or overuse muscles: Long periods of standing, intense exercise, or muscle fatigue can trigger cramps.
- People who are dehydrated: Low fluid intake or heavy sweating may contribute.
- People with mineral or nutrient imbalances: Low levels of certain electrolytes (such as magnesium, potassium, or calcium) can sometimes be involved.
- People with circulation or nerve problems: Conditions affecting blood flow or nerves may increase risk.
- People taking certain medications: Some medicines, including certain diuretics and cholesterol-lowering drugs, may be associated with muscle cramps.
- People with medical conditions: Diabetes, kidney disease, thyroid disorders, and some neurological conditions can increase susceptibility.
To reduce the chance of night cramps, helpful habits may include staying hydrated, stretching calf and leg muscles before bed, maintaining regular activity, and avoiding sudden increases in exercise intensity.
Seek medical advice if cramps are frequent, severe, cause weakness or swelling, disturb sleep regularly, or occur with numbness or other new symptoms.
