The perception of saunas, subjective sensations, pleasant, warm, feeling better after a bath, a sense of courage and strength, good mood and tranquility - a bouquet of psychological sensation, probably best reflects the effect of baths on the central nervous system and mental functions in humans. Anger and hatred burned in a sauna - so vividly defines the mental state after the sauna Finnish folk proverb.
Indeed, numerous observations of scientists, athletes, doctors showed an improvement of the central nervous system and mental processes and improving the functions of the neuromuscular apparatus in humans after a bath.
However, not all cases, the conditions baths gave such an effect. Russian scientists SD Kostyurin in 1883 and later Soviet scholars KA Burtsev in 1936, and especially AV Fos-michev in 1937, noted after a bath with high humidity or excessive heat, as well as prolonged presence in the bath in the early hours of reduced muscle strength, a sense of fatigue, weakness, bad mood, decrease efficiency. Athletes, boxers in the observations AV Fomichev, especially long applied the steam bath to reduce body weight, lost the match in the ring.
Moderate effect of steam bath in the experiments SD Kostyurin already the next day resulted in improved well-being and increase muscle strength.
As suhovozdushnyh bath - saunas, dry winds, they are in most cases, provide a more rapid improvement in the functions of the nervous and muscular system. However, this effect appears not under all circumstances saunas. If the temperature in the sauna does not exceed 80-90 ° C at low humidity (5-10%), as a rule, the strength of muscles in humans increases, improved mood and these changes are kept for a long time - from 24 to 48 hours
Another Russian scientist, FI Argentov said after suhovozdushnoy baths (such as the Roman baths) an increase in muscle strength. Studies Austrian doctor Procope in 1956 and the German coach Sean in 1957 showed improvement in all functions of the neuro-muscular athletes after taking a sauna. Sean, in particular, the increase in strength with push shot put, jumping in the long jump, the duration of static muscle tension, and Prokop observed an increase in muscle strength, which was kept to 48 hours
Soviet scientists FI Talysh and VU Avanesov in 1970 found that the sauna increases physical performance by 15%. KA Kafarov in 1967, observed in athletes after taking the sauna for 10 minutes increased the light sensitivity of eyes to 40,5%, the speed of motor reaction to light and sound signals at 6,9, and 8%, accuracy of movements for 25, 8%, the strength of back muscles by 2,7% and vshoslivost to the dynamic work of 14,1%. What does all this mean? Of course, the improvement of the central nervous system and muscular system. As is known, in the nervous system play a big part strength and balance, agility and endurance of the two cortical processes: inhibition and excitation. Steam treatments help to increase mobility, balance, strength and endurance of these processes. Hence, the calm (balance), and high speed movements, and their accuracy (mobility and balance of nerve processes), and long-term performance (endurance nerve processes), observed after using the sauna. Central nervous system and muscular system subordinate to it are very sensitive to changes in temperature and humidity in the bath.
