Stretching, exercising, drinking enough fluids and regulating one's diet are strategies to help prevent leg cramps recommended by WebMD. Wearing supportive shoes and sleeping with loose sheets are also effective, states the Chicago Tribune. Adjusting sleeping position is a helpful technique proposed by Harvard Medical School.
Daily stretching keep cramps at bay, especially if done before and after exercising, WebMD reports. If night- time cramps are typical, calf and foot muscles should be stretched just before going to bed, according to Harvard Medical School. One effective stretch is to stand on the lowest step and gradually drop the heels until they hang below the edge of the step.
Strengthening muscles through exercise such as biking -- either moving or stationary -- aids in preventing cramps, WebMD suggests. To avoid nocturnal cramps, gentle biking is done before retiring, advises the Chicago Tribune.
Muscles sometimes cramp due to dehydration, so fluids should be consumed throughout the day, WebMD notes. Cramp sufferers should drink enough to turn their urine light yellow. A healthy diet that contains significant amounts calcium, potassium and magnesium is also important for cramp prevention, as is a daily multivitamin.
When sleeping, legs should be able to move freely, so bed sheets and blankets are not tucked in, advises Harvard Medical School. Letting the feet hang over the end of the bed and sleeping on the stomach sometimes help prevent leg cramps, as well.
