What is the fastest way to relieve leg cramps during sleep?

The main solutions for leg cramps during sleep can be summarized as follows: 1. The quickest method is to immediately stretch the affected leg. Straighten the leg on the bed and pull the toes toward you by hand, which stretches the muscles at the back of the leg and rapidly relieves pain. 2. Apply a hot water bottle or warm towel to the cramped area to promote local blood circulation and help alleviate muscle spasms. Heat application should last about 10–20 minutes. 3. Sleeping on your side for prolonged periods may compress the legs and trigger muscle cramps. It's advisable to adjust sleeping positions regularly, preferably lying flat on your back. 4. If cramps are caused by calcium deficiency, ensure adequate calcium intake in daily life by consuming more calcium-rich foods or taking calcium supplements as needed.
