Leg cramps at night, often referred to as “charley horses,” are involuntary spasms of the leg muscles, usually with painful cramps in the calves, although they can also occur in the thighs or legs. These cramps usually occur while you’re resting, especially at night, and can range from mild discomfort to severe pain that disrupts sleep. These crabs are generally harmless, but frequent occurrences can interfere with your sleep quality and well-being.
Common causes of leg pain at night
Dehydration
One of the main causes of night pain is dehydration. When the body lacks enough fluid, electrolytes are imbalanced, especially minerals such as sodium, potassium, magnesium, and calcium. These electrolytes are essential for normal muscle function, and when imbalanced, muscles can contract involuntarily.
Muscle fatigue or overexertion
Intense physical activity or muscle strain during the day can cause pain at night. If your leg muscles are overworked, they may tighten and cramp while you rest and recover. Standing or sitting for long periods of time can cause muscle fatigue, especially if you don’t stretch properly before or after exercise.
Poor circulation
Decreased blood flow to the legs can contribute to swelling, especially when lying in a certain position for a long time. Peripheral artery disease (PAD) or venous insufficiency can reduce circulation and increase the likelihood of swelling.
