The Finnish sauna differs from the Russian sauna with a more dry steam, allowing you to raise the temperature in the sauna to 90-100 degrees. Under the influence of temporary overheating, all body functions are activated: blood circulation, respiration and metabolism. Low humidity (less than 15%) makes it possible to warm up well and breathe air, rich aromas of motley grass, and also promotes greater sweating and release of the body from various slags.
The most apparent influence of the sauna is on heat exchange, blood circulation, functions of the autonomic and central nervous system. During the procedure, the human body temperature rises by 1-2 ° C, which leads to a number of adaptive reactions aimed at increasing the reserves of the cardiorespiratory system, immune reactivity, neuro-endocrine and other body systems.
In the process of taking a sauna in the first minutes, the temperature of hot air acting on the skin and mucous membranes of the respiratory tract causes a response in the form of hyperemia. With further stay in the sauna, internal organs are heated. The process includes thermoregulation mechanisms - increased sweat secretion and its evaporation, which contributes to heat transfer and maintenance of heat balance (for every 100 grams of evaporated perspiration the body loses 242.8 kJ on average).
Sauna is used by both adults and children (from the age of three).
