Night cramps—sudden, painful muscle spasms that often wake people from sleep—can affect anyone, but some groups are more vulnerable than others. Knowing the risks can help with prevention.
Older Adults
Nearly one-third of adults over 60 report regular night cramps. Aging muscles lose flexibility, nerves transmit signals less efficiently, and circulation slows—especially to the legs and feet. This combination makes seniors particularly prone to nighttime spasms.
Pregnant Women
Leg cramps are a common complaint in pregnancy, especially during the second and third trimesters. Added weight strains leg muscles and veins, while hormonal changes can alter fluid and electrolyte balance. Reduced circulation also plays a role, leaving muscles more sensitive to cramping.
Athletes
Even healthy, active people are at risk. Intense training and long workouts fatigue muscles, deplete fluids, and drain electrolytes like potassium and magnesium. Without proper stretching and hydration, athletes often wake up with painful calf or foot cramps.
Sedentary Lifestyles
Prolonged sitting or standing also increases risk. Poor circulation and stiff muscles from inactivity make cramps more likely at night.
Office workers, retail employees, or those who stand still for long periods often struggle unless they move and stretch regularly. Night cramps are common but manageable—hydration, stretching, and balanced electrolytes can help reduce their frequency.
