Nocturnal leg cramps, or nocturnal cramps, are sudden, involuntary spasms or spasms of the leg muscles that usually affect the calves, thighs, or feet. These cramps can be very painful and last from seconds to minutes, disrupting sleep and leaving a lingering pain. Although usually associated with the elderly, leg pain at night can occur in people of all ages. Understanding the root cause of leg pain at night can help you find effective solutions and prevent future occurrences.

Common causes of leg pain at night
Dehydration
One of the most common causes of muscle stiffness at night is dehydration. Muscles require a balance of water and electrolytes (sodium, potassium, calcium, magnesium, etc.) to function properly. When the body is dehydrated, this balance is disrupted, leading to muscle stiffness and spasms.

Electrolyte imbalance
Electrolytes help regulate nerve and muscle function. Deficiencies or imbalances in key minerals, especially magnesium, potassium or calcium, can cause night pain. These minerals play an important role in muscle contraction and relaxation, so when levels are low, muscle contractions are more likely to occur. This imbalance can be caused by inadequate nutritional intake, certain medications (such as diuretics), or excessive loss of electrolytes through sweat and urine.
