Why You Might Get Cramps at Night
Nighttime leg cramps are sudden, painful muscle contractions, most often in the calf, although the feet and thighs can also be affected. In many cases, the exact cause isn’t known.
Common reasons
- Dehydration — Not drinking enough fluids can contribute to muscle cramps.
- Muscle fatigue or overuse — Hard exercise, physical work, or unusually strenuous activity can leave muscles more prone to cramping.
- Long periods of sitting or inactivity — Spending much of the day sitting can be associated with nighttime cramps.
- Certain medications — Some medicines, including certain blood-pressure medicines and cholesterol-lowering drugs, can be associated with cramps.
- Electrolyte or nutritional problems — Abnormal levels of minerals such as potassium, calcium, or magnesium can sometimes contribute, although not every nighttime cramp means you’re deficient.
- Getting older — Night leg cramps become more common with age.
- Pregnancy — Leg cramps are particularly common during pregnancy.
- Nerve, circulation, kidney, thyroid, or diabetes-related problems — These conditions can sometimes be associated with recurrent cramps.
