• Soothe the pain by dipping your leg in lukewarm water before sleeping. 
   
• Potassium intake is very important — consume at least two bananas daily to keep leg cramps at bay. 
   
• Massaging the affected area with Eucalyptus or Lavender oil helps a lot in easing the pain. 
   
• Drink six to eight glasses of water daily. This will prevent dehydration, which may play a role in the cramping. 
   
• Take out some time throughout the day to do leg stretches. Stretch the muscles that are cramped but do it gently. 
   
• Leg cramps are sometimes a sign of electrolyte imbalance. Increase your consumption of magnesium and calcium by eating lots of green leafy vegetables and low fat dairy products. 
   
• Try squeezing your upper lip by applying pressure from your index finger and thumb. This acupressure technique really works. 
   
• Those who are suffering from leg cramps at night should consume one tablespoon of honey before going to bed. The intake of honey will decrease the chance of muscle contraction occurrence at night.
