Night cramps are sudden, painful muscle contractions that often strike during sleep. While they can affect anyone, some groups are more vulnerable.

Older adults are especially at risk. “Nearly one-third of people over 60 experience night cramps regularly” due to reduced muscle elasticity, weaker nerve function, and slower circulation.

Pregnant women also face frequent cramps, especially in later trimesters. Added weight, hormonal shifts, and “altered blood flow and pressure on veins” often make leg spasms a common pregnancy complaint.

Athletes and active individuals may suffer from overworked or dehydrated muscles. “Heavy sweating depletes essential electrolytes like potassium and magnesium,” making cramps more likely without proper recovery and hydration.

Sedentary lifestyles also contribute. Long hours of sitting or standing restrict blood flow and stiffen muscles, while medical issues like diabetes, kidney disease, or thyroid disorders may trigger cramps through poor circulation or imbalance. Some medications—including diuretics and cholesterol drugs—can also increase the risk, making medical advice important if cramps persist.
