While anyone can get a night cramp, certain groups are much more likely to experience them regularly.
1. Adults Over Age 60
Up to 50–60% of older adults report regular night cramps
Muscle mass declines with age → less support and circulation
Slower nerve signaling may contribute
🩺 Often worse at night due to reduced movement during the day.
2. Pregnant Women (Especially in the Third Trimester)
Up to half of all pregnant women experience leg cramps
Likely due to:
Pressure from the growing uterus on nerves and blood flow
Changes in circulation and mineral balance (calcium, magnesium, potassium)
Usually resolves after delivery.
3. People Who Sit for Long Periods or Are Sedentary
Prolonged sitting shortens calf muscles → increases spasm risk
Lack of daily movement reduces circulation and muscle tone
Office workers, drivers, and those recovering from injury are especially prone.
4. Athletes or Those Who Overuse Muscles
Intense exercise without proper warm-up/cool-down
Dehydration or electrolyte imbalance (from sweating)
Muscle fatigue → increased cramping at night
✅ Even fit individuals aren’t immune.
5. People with Certain Medical Conditions
✅
Peripheral Artery Disease (PAD)
Poor blood flow to legs
✅
Diabetes
Nerve damage (neuropathy), circulation issues
✅
Kidney Disease
Electrolyte imbalances (low calcium/potassium)
✅
Neurological Disorders
ALS, Parkinson’s, spinal stenosis
✅
Thyroid or Liver Issues
Metabolic disruptions
If cramps are frequent and unexplained, see a doctor.
