Night convulsions.

The phenomenon of convulsive contraction of the muscles in the limbs during sleep is a problem for many people, regardless of age and gender. The factors that provoke night convulsions are of various origins:

Physical muscle overload;
Dehydration of the body (even slight);
Disturbances in the structures of the musculoskeletal system (deformations, cracks, bone growths);
Diseases associated with metabolic disorders in the body (diabetes mellitus, endocrine disorders, hormonal disruptions and hormonal changes);
Diseases associated with disorders in the nervous system;
Medicines used to treat other diseases, but which have seizures as side effects.

The mechanism that causes convulsive contractions of muscle tissue is based on a disruption in the work of ion channels, which provide the contractile ability of muscle fibers, moving calcium, magnesium, potassium and sodium ions through cell membranes into cells from the intercellular space. These processes occur during a person's wakefulness, when he needs muscle tone and muscle work for movement and other types of life.

Calcium channels move calcium ions into cells through cell membranes and provide slow potentials (the rate of conduction of an electrical impulse and the response of muscle cells to it), as well as spontaneous generation of action in muscle fibers. During sleep, calcium ions are collected in the bone tissue depot. In addition, potassium, magnesium and sodium are needed to maintain muscle contractile function. Potassium is responsible for the degree of excitability of muscle cells and the state of rest. Magnesium controls the alternation of periods of rest and contraction of muscle fibers. Sodium generates a state of action. Together, the ions of calcium, magnesium, potassium and sodium are involved in the processes of alternating contraction and relaxation of muscle fibers.

It is for this reason that it is so necessary to maintain the mineral balance in the body and include in the diet foods rich in the aforementioned microelements. In cases where it is necessary to provide significant support to the work of the muscular apparatus, drugs with an increased content of calcium, potassium, magnesium or sodium are prescribed. Such drugs must be taken under the supervision of a physician, since they can disrupt the course of metabolic processes and cause a number of painful conditions: hypercalcemia, hypermagnesemia, hyperkalemia, hypernatremia.
