In a healthy person, regular quenching with cold water two to three times a week increases blood flow and strengthens immunity to seasonal viral infections, while the temperature of the water should be reduced gradually over six months. Sergey Bondarev, Professor of the Department of Sports Medicine and Medical Rehabilitation of the Institute of Clinical Medicine named after Sklifosov Sechenov University, told the Moscow City News Agency about this.
“Proper hardening leads to increased blood flow in the muscles, quickens breathing, and also activates the immune system, which allows you to fight seasonal viral diseases. It is important to emphasize that the increase in cold loads during hardening should be gradual. Prepare for minimum temperatures for six months. I advise you to break this period into equal intervals with a gradual decrease in water temperature - from 22 degrees Celsius in the first days of hardening to 5 degrees Celsius at the end of the sixth month. Impacts should be short-term and fairly regular - at least two to three times a week,”Bondarev said.
He noted that neglect of safety rules can lead to hypothermia and over-stress for the body. Even for a trained person, the minimum permissible air temperature for hardening should be at least 2-3 degrees of frost.
“Suddenly going outside and dousing with cold water without any preparation or training is likely to lead to over-stress and can exacerbate chronic illness or the development of acute illness. The ambient temperature for a trained person should not exceed the temperature of a slight frost - about 2-3 degrees, and even a person should approach it gradually. After dousing, you must immediately be in a warm room and dry yourself thoroughly so that there is no cooling of the body due to vapors, "Bondarev specified.
As he recalled, hardening is contraindicated for many people, it is recommended to consult a doctor before the procedure. “There are many contraindications here. Each case must be discussed individually with the attending physician. This primarily concerns patients who have neurological disorders and a tendency to convulsive syndromes. They are also patients with chronic lung diseases in the acute stage and patients with bronchial asthma that develops in response to cold. Naturally, these are patients with diseases of the cardiovascular system, with hypertension. Simply put, all patients who have certain risks to the development of unstable conditions,”added Sergei Bondarev.
