Waking up in the night with stabbing calf pain is surprisingly common. Nighttime leg cramps—sudden, involuntary muscle contractions, usually in the calves or feet—affect millions of people. While often harmless, they can sometimes signal deeper health concerns.
Occasional cramps are usually linked to dehydration, overuse, prolonged sitting, awkward sleep positions, pregnancy, or electrolyte imbalances. These usually pass quickly and can be eased with stretching. But frequent or severe cramps may point to circulation issues, nerve problems, or medication side effects.
When should you worry? If cramps strike more than three nights a week, cause lingering pain, disturb your sleep, or come with swelling, weakness, tingling, or dark urine, it’s time to consult a doctor. Conditions like peripheral artery disease, kidney dysfunction, or diabetes-related nerve damage could be involved.
Prevention often comes down to simple habits: staying hydrated, stretching before bed, moving throughout the day, wearing supportive shoes, and checking sleep posture. Magnesium, potassium, and calcium-rich foods can also help.
By preparing your body for rest—hydrated, stretched, and supported—you can greatly reduce painful nighttime cramps and protect your sleep.
