🧠 What Are Night Cramps?

Night cramps (also called nocturnal leg cramps) are sudden, involuntary contractions of muscles — most commonly in the legs.

They’re different from:

• Restless legs syndrome (RLS) – a tingling urge to move the legs
• Charley horses – similar but can occur during activity
• Muscle spasms from injury – caused by trauma or strain

✅ While uncomfortable, they’re usually not dangerous — but frequent cramps can disrupt sleep and quality of life.
