Leg cramps at night, often called nocturnal leg cramps, are painful muscle spasms that can disrupt sleep. These cramps commonly affect the calves, thighs, or feet, and their exact cause isn’t always clear. However, a mix of lifestyle, health, and physiological factors contribute to this discomfort. Let’s explore the reasons behind these cramps and actionable steps to prevent them.

Why Do Legs Cramp at Night?

Dehydration

Lack of fluids can impair muscle function and cause spasms.

Electrolyte imbalances, particularly low magnesium, potassium, or calcium levels, are culprits. Inactivity or Overuse

Long periods of sitting or standing can strain muscles.

Strenuous exercise without proper stretching may lead to cramps.

Poor Circulation

Restricted blood flow reduces oxygen supply to muscles, leading to spasms.

This may be linked to conditions like peripheral artery disease.
