You’re fast asleep.
Then, without warning — a sharp, tightening pain shoots through your calf. Your foot twists. You can’t move.
It’s a nocturnal leg cramp — sudden, intense, and all too familiar to millions.
These involuntary muscle contractions typically strike in the calves, feet, or thighs and can last from a few seconds to several minutes. While not dangerous, they can:
- Disrupt sleep
- Cause lingering soreness
- Affect quality of life — especially in older adults
And yes — some people are far more likely to experience them than others.
Let’s explore who’s most at risk, why night cramps happen, and what you can do to reduce their frequency — so you can rest easier, longer, and pain-free.
Because real relief isn’t about magic cures. It’s about understanding your body — one quiet night at a time.
