Don’t Ignore Leg Cramps at Night: Here’s What You Should Know
Nighttime leg cramps are sudden, painful muscle contractions—often in the calf or foot—that can wake you from sleep. They’re common, especially with increasing age, and most aren’t caused by something dangerous. But frequent or severe cramps deserve attention because medications and certain medical conditions can sometimes contribute.
What you can do during a cramp
-
Gently stretch the muscle. For a calf cramp, straighten your leg and pull your toes toward your face.
-
Massage the cramped muscle gently.
-
Stand up and walk around carefully if you’re able.
-
Applying warmth with a heating pad or warm shower may help relax the muscle.
Why might they happen?
Possible contributors include:
-
Muscle fatigue or prolonged standing
-
Dehydration
-
Certain medications, including some diuretics and cholesterol-lowering medicines
-
Pregnancy
-
Nerve or circulation problems
-
Some metabolic or neurological conditions
Despite what you may see online, magnesium isn’t a universal cure for nighttime cramps. Magnesium supplements generally aren’t helpful for ordinary age-related leg cramps unless a deficiency or another specific reason is present.
How to reduce them
Regular calf and hamstring stretching, particularly before bedtime, may help some people. Stay adequately hydrated and avoid suddenly increasing strenuous exercise.
Don’t stop prescription medicines or start high-dose supplements on your own. If cramps began after starting a medication, ask your doctor or pharmacist whether it could be contributing
