How to stop a night-time calf cramp — and reduce the next one
There are two separate problems: stopping the cramp that has you awake right now, and lowering the odds that it happens again tomorrow. They need different answers.

In the moment
Passive stretch is the single most reliable way to break an active cramp. Lengthening the cramping muscle increases inhibitory feedback and quiets the runaway firing.
- Straighten the knee and pull the toes up toward the shin, holding until the spasm releases
- If you can stand, put weight on the ball of the foot with the heel pressing down
- Then walk a few steps and stretch again gently before lying back down
- Warmth afterwards can ease the residual ache; do not force a painful stretch on a tender muscle
The evening routine with the best support
Stretching studies in older adults have shown reductions in cramp frequency and severity when calf and hamstring stretches are done nightly and consistently over weeks. Consistency matters more than duration.
- Wall calf stretch, both legs, held without bouncing
- Standing or seated hamstring stretch
- A short walk or gentle cycling earlier in the evening
- Neutral foot position in bed and loose bedding
What to be sceptical about
Quinine is no longer recommended for cramps in most guidance because of the risk profile. Many supplements are marketed for cramps on thin evidence. If a product claims to eliminate cramps outright, treat that claim carefully and discuss it with your clinician.
