Frequent leg cramps are mostly caused by calcium deficiency, cold, and local nerve and blood vessel compression.

Usually, you can supplement calcium in an appropriate amount, spend more time in the sun, pay attention to local warmth, and also pay attention to your posture. Changes, such as sitting or sleeping, can avoid compression of nerves and blood vessels. You can also apply hot compresses and massage to local muscles to enhance local blood circulation. If there is still no improvement, you should go to the hospital for examination and treatment.

Here are 4 tips to prevent leg cramps before they occur:

Wear comfortable shoes. Flat feet and other anatomy issues make some people particularly susceptible to leg cramps. Proper shoes are one way to compensate.

Stretch your muscles. Stretching your gastrocnemius and foot muscles before bed can help prevent cramps in the first place. Stretch the same way you would stretch your gastrocnemius and foot muscles when you have leg cramps. You can also place the front of your foot on the first step of the stair step, and slowly press down on your heel so that the heel position is lower than the step position.

Drink plenty of water. If you're active (including walking, gardening, and housework), you'll need to drink more fluids to avoid dehydration, but don't overdo it. Large amounts of fluid can dilute the concentration of sodium in the blood, which can cause a variety of problems, including muscle cramps. How much water you should drink depends on your activity level and the food you eat. Because thirst stimuli become weaker with age, we may forget to drink enough water as we age. Some people are also worried that drinking too much water will cause them to go to the toilet more often, especially at night.
