Principles and methods of hardening in cold water
The problem of modern man is that he is surrounded by comfort, so do not feel permanent environmental effects, including the cold on the body. This significantly reduces its ability to adapt to environmental changes, so even a slight hypothermia can reduce the body's defenses.
How does the hardening of cold on the human body
Cold Tempering - increased resistance to the effects of cold by regular training influence various cold factor. Especially effective quenching with cold water.
Modern man protects against environmental influences clothing, a warm room, car and other benefits of civilization. It is a complete break between man and his environment and the violation of its adaptive capacity. In this case, improving adaptation to the environment is achieved by hardening.
Hypothermia - the most common cause of acute respiratory diseases. A complex system of thermoregulation of the body, allowing it to maintain constant temperature of the internal environment, regardless of changes in ambient temperature, consists of two mechanisms - the physical and chemical thermoregulation. Physical thermoregulation - a regulation of heat supply through the expansion or narrowing of blood vessels in the skin: the cold, they are narrowed and give less heat. But there comes a time when it does not help, then included the chemical mechanisms of thermoregulation - the acceleration of metabolic processes, resulting in more heat is produced. In addition, multiple systematic skin cooling leads to a thickening of the superficial skin layer, which also increases its thermal insulating properties.
It is found that the heat generation in human quenched cold is greater than the nonhardened, so when strong cooling heat balance balance he maintained longer. At the same moment the cooling quenched cold skin temperature of people above and the skin appears warmer to the touch than the unquenched due trenirovannosti blood vessels and adjustment of metabolism

. This greatly increases their resistance, as a cold and frostbite.
The basic principles of hardening cold water
In order to train the blood vessels to the rapid contraction or expansion, restructure metabolism

a quick reaction to cold and to increase the protective reaction of the body, must act systematically and gradually:
- should respect the principle of constant growth of the quenching effects of cold water, that is lowering its temperature;
- if signs of hypothermia effects should be discontinued;
- water treatment should be carried out every day, combining them with the gym - it increases the degree of adaptation to cold;
- hardening technique should be individualized, based on age, fitness, presence of chronic diseases and preferences of an individual.
It should also be remembered that after the termination of the degree of tempering procedures tempered weakens and disappears in 2-3 months.
Methods for hardening
Water treatments - this is quite a strong effect on the body, so if a person had not engaged in hardening and is prone to colds, it is best to start with tempering air. To do this, every day a few hours to spend in the open air, it is better if it is combined with hiking. Houses can take an air bath, fully clothed, and gradually increase the duration of these procedures. And only after a person has adapted to the cool air, you can start hardening in cold water.
Water - the more vigorous quenching factor than air, its thermal conductivity many times greater than the thermal conductivity of air. In addition to temperature, water and has a mechanical impact on the receptors in the skin, which is a kind of massage that improves capillary blood circulation and lymph flow. The most common form of tempering water in the home - a rubdown and pouring. You can also use the swimming in the pool or in open water.
Begin hardening water should be at a temperature not lower than its 34-35˚S. Then (in the daily conduct of procedures) to reduce the temperature of the weekly 1˚S, bringing it gradually to 22-24˚S, and then continue wiping and pouring water temperature of 2-3 months. In the absence of colds, anxiety and sleep disorders
Dreams: how to understand our dreams
you can go to the hardening of the water of a lower temperature, reducing it every 10 days leading up to and 1˚S 10-12˚S (ordinary tap water temperature). Any water treatment usually end rubdown with a dry towel light massage to enhance circulation.
Hardening does not take much time, but brings great benefits: fewer people colds, becomes more active during the day and sleep better at night.
