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.
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.
