Waking up suddenly with a tight, painful knot in your calf or foot is more than just annoying — it can be downright jarring.
You’re not alone.
Nocturnal leg cramps affect up to 60% of adults, especially as we age. They’re common, usually harmless, and often predictable — but that doesn’t make them any less uncomfortable.
The good news?
In most cases, they’re not a sign of serious illness — and there are simple, effective ways to reduce how often they happen.
Let’s explore what causes nighttime leg cramps, when to be concerned, and what you can do to finally get a cramp-free night’s sleep.
🧠 What Are Nighttime Leg Cramps?
Nighttime (nocturnal) leg cramps are sudden, involuntary contractions in the calf, foot, or sometimes thigh muscles.
- They can last from a few seconds to several minutes
- May leave soreness afterward
- Are different from restless legs syndrome (which causes an urge to move, not pain)
✅ Common — but not inevitable.
