The Reasons Why You Get Leg Cramps at Night and How You Can Solve Them

Nighttime leg cramps are painful sensations often occurring while you’re asleep, potentially waking you up. These cramps, usually affecting the calf muscles, are typically caused by prolonged periods of inactivity. The pain from nighttime leg cramps can vary, lasting from a few seconds to several minutes. Even after the cramp has passed, you may continue to experience muscle pain throughout the night or the next day.

Leg cramps at night? Causes and treatments

Leg cramps at night or restless legs syndrome?

Distinguishing between nocturnal leg cramps and restless legs syndrome (RLS) is essential, as they both occur during sleep but present different characteristics:

  • RLS does not cause pain or cramps; this feature is specific to night cramps.
  • RLS induces a desire to move the legs, while night cramps often hinder movement.
  • Movement relieves RLS, whereas moving the leg with cramps requires stretching.

  • Prolonged periods of sitting.
  • Excessive strain on the leg muscles.
  • Unsupportive flooring such as reinforced concrete or sand.
  • Poor sitting posture.

Certain medical conditions may contribute to nighttime leg cramps, including pregnancy, alcoholism, dehydration, Parkinson’s disease, neuromuscular issues, structural problems like flat feet, and diabetes.
