What causes leg cramps and are they serious?

Leg cramps are very common in our lives. Most of them are caused by muscle stiffness, calcium deficiency, and cold after exercise. If some people have incorrect posture after exercise, this phenomenon will also occur.

Muscle stiffness: If you are walking on the road and a motorcycle thief snatches your bag, your reaction will definitely be to chase him quickly. This sudden and violent movement without any warning can cause great damage to the muscles. When the motorcycle thief drives away and you give up chasing him, your muscles suddenly relax, which makes it easy for you to have muscle spasms.

Calcium deficiency: Calcium can reduce muscle nerve activity. If the body lacks calcium, the muscle nerves will be overexcited, which can easily cause cramps.

Being exposed to cold after exercise: Muscles become relaxed after exercise. If they are exposed to cold, the nervous system will stimulate the muscles to generate heat through rapid muscle contraction, making the muscles prone to spasms.

Wrong posture after exercise: Body posture can also cause muscle cramps. For example, curling up your legs after exercise can easily cause cramps, and the same is true if you curl up your body when sleeping.
