You’re sleeping peacefully when suddenly, a sharp pain jolts you awake—as if your calf has decided to rebel in the middle of the night. These nighttime cramps are common, but that doesn’t make them any less painful. Worse, they often leave behind a lingering soreness that can last for hours.

Where do these cramps come from, and more importantly, how can you stop them from disturbing your rest?

The Hidden Causes of Night Cramps

1. Certain medications
Diuretics, antidepressants, or hormone therapies can sometimes cause muscle-related side effects. If your cramps began after starting a new prescription, it’s worth discussing with your doctor.

2. Pregnancy
Cramps are especially common during the second and third trimesters of pregnancy. They’re usually harmless, but nutritional adjustments or supplementation under medical supervision may help.

3. Dehydration
Even mild dehydration can affect muscle function and trigger cramping. Staying consistently hydrated throughout the day is essential.

4. Prolonged standing
Spending hours on your feet, especially on hard surfaces, fatigues the muscles. Taking breaks to sit, walk around, or elevate your legs can help.
