Why Do We Get Cramps at Night?
Nighttime leg cramps are sudden, painful muscle contractions, most often affecting the calf, foot, or thigh. They’re common and usually harmless, but the exact cause often isn’t known. (Mayo Clinic)
Common contributors include:
- Muscle fatigue or overuse, particularly after strenuous activity.
- Dehydration, especially after sweating or being active in hot weather.
- Long periods of sitting or inactivity.
- Certain medications, including some diuretics, blood-pressure medicines, and statins.
- Age-related changes in muscles and nerves.
- Less commonly, conditions involving the nerves, kidneys, thyroid, blood circulation, or diabetes. (Mayo Clinic)
What can help?
When a cramp strikes, gently stretch the affected muscle, pull your toes toward your face during a calf cramp, massage the muscle, or stand and put weight on the affected leg. Heat or a warm shower may also provide relief. (Mayo Clinic)
To reduce nighttime cramps, staying adequately hydrated and doing gentle calf stretches before bed may help. (nhs.uk)
See a healthcare professional if cramps are frequent, severe, last longer than about 10 minutes, repeatedly disrupt your sleep, or occur with swelling, numbness, weakness, or skin changes. (nhs.uk)
