What causes calf cramps? Four reasons to pay attention to

Calf cramps are very common in our lives. This situation is most common in winter. Generally speaking, there are reasons for calf cramps. So, what are the causes of calf cramps?

①Cold stimulation.

For example, exercising in a cold environment in winter and not doing enough warm-up activities, or swimming in low water temperature in summer, can easily cause leg cramps. If you don't cover yourself with a blanket at night, the calf muscles will be stimulated by the cold and will cramp, causing you to wake up in pain.

② Muscles contract too quickly and continuously.

During strenuous exercise, the whole body is in a state of tension, the leg muscles contract too quickly, the relaxation time is too short, the local metabolic product lactic acid increases, the muscle contraction and relaxation are difficult to coordinate, thus causing calf muscle cramps.

③Excessive sweating.

Long exercise time, high volume of exercise, excessive sweating, and failure to replenish salt in time will lead to a large loss of fluid and electrolytes in the body, accumulation of metabolic waste, poor blood circulation in the local muscles, and prone to cramps.

④Excessive fatigue.

When traveling long distances, climbing mountains, or ascending to a certain height, the calf muscles are most likely to become fatigued. Because every time you ascend, one leg supports the weight of the whole body, and the force required for the muscles in this leg to lift the foot will be six times the weight of the human body. When it becomes fatigued to a certain extent, cramps will occur.
