What causes cramps all over the body? What causes frequent cramps?

Speaking of "cramps", the most memorable one was when I was swimming and suddenly my middle finger cramped. Luckily there were people around at the time. So what are the causes of whole body cramps?

Causes of cramps throughout the body

Common causes of systemic convulsions include epilepsy, febrile convulsions, tetany (hypocalcemic convulsions), hysterical convulsions, hyperventilation syndrome, etc.

7 reasons for frequent cramps

①Cold stimulation

Cold stimulation from the external environment, such as low room temperature at night in winter, using a quilt that is too thin or exposing legs and feet outside the quilt when sleeping, and low swimming water temperature in summer can easily cause leg cramps.

②Excessive fatigue

Fatigue, lack of sleep, rest or too much rest can cause accumulation of local acidic metabolites, which can cause muscle cramps. When traveling long distances, climbing mountains, or climbing high places, walking or exercising for too long, excessive fatigue of the lower limbs or lack of rest and sleep can cause lactic acid accumulation, and the calf muscles are most likely to become fatigued. When fatigue reaches a certain level, cramps will occur.

③Osteoporosis

Elderly women have decreased estrogen levels and osteoporosis, which can cause low blood calcium levels, increased muscle irritability, and frequent cramps.

④Sleeping posture

Bad sleeping posture, such as lying on your back for a long time with the quilt pressing on your feet, or lying on your stomach for a long time with your feet against the bed, forces certain calf muscles to be in an absolutely relaxed state for a long time, causing passive muscle contraction.

⑤ Calcium deficiency

Calcium ions play an important role in muscle contraction. When the concentration of calcium ions in the blood is too low, muscles are easily excited and spasm. Teenagers grow and develop rapidly and are prone to calcium deficiency, so leg cramps often occur.

⑥Muscle contraction

During intense 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 spasms.

7. Excessive sweating

Long exercise time. If the amount of exercise is large, sweating is heavy, and salt is not replenished in time, a large amount of fluid and electrolytes in the body will be lost, metabolic waste will accumulate, and the blood circulation in the local muscles will be poor, which will easily cause cramps.
