【Introduction】One of the effects of the hot spring provides worm temperature. This effect raises temperature, and temperature control function operates and causes increase of the bloodstream. This time, these changes examined the thing by the size of the bathtub and the spring quality of the hot spring.
【Subjects and Methods】The subjects were 10 healthy adult men (mean age: 25.2 years). They bathed for 10 min in bathtubs at 42°C. The enforcement used plunge bath (approximately 1,700 L: simple alkaline hot spring) and home bathtub (approximately 300 L: hot water, 0.1% artificially chlorinated spring). Measurement item of the maximum arterial blood flow rate using the Ultrasonic Rheometer Smart Doppler 45, deep body temperature using the deep body temperature monitor core temperature CM-210, I compared each value 10 min during the bathing, and during a 10-min, 20-min, 30-min resting period after bathing, furthermore, I found the conjugation on each condition resting period after bathing.
【Result】The rise in deep body temperature and maximum arterial blood flow rate showed the result that a hot spring of the plunge bath was more meaningful than the value of the home bathtub after 10 min of bathing. The deep body temperature of the hot spring of the plunge bath significantly rose from bathing 3 min after. In deep body temperature with the resting period after bathing, in the hot spring of the plunge bath, a meaningful rise was maintained in hot water 13 min for population chloride spring 16 min of the home bathtub for 15 min.
【Discussion】In thinks that a population spring let you maintain a temperature rise that it disturbs a drop of the water temperature by abundant quantity of water in the plunge bath that hot spring plunge bath had a bigger deep body temperature rise, maximum arterial blood flow rate than home bathtub, and the deep body temperature rise in the home bathtub was continued.
Foot baths reportedly reduce pain and improve sleeplessness. In addition, foot baths may induce vasodilation, and thereby improve blood flow, reduce swelling, induce relaxation, and increase deep body temperature. However, the influence of foot baths on energy metabolism and physiological indices are unclear. Therefore, the present study aimed to clarify the effects of foot baths on energy consumption and physiological indices (e.g., heart rate, tympanic temperature, and blood pressure). Nine healthy males were included in this study (age, 23.0±1.0 years; body weight, 66.5±5.6 kg; body fat percentage, 15.1±4.3%). Expired gas composition (i.e., oxygen and carbon dioxide consumption) was analyzed using the Food method in an environmentally-controlled room (room temperature 25°Cand humidity 40%). Subjects were rested in the hood during the measurement. After 30 min rest in the sitting position, a 30 min foot bath was performed, after which the subjects sat for 60 min. Expired gas composition and heart rate were measured over time, and tympanic temperature and blood pressure were measured every 15 min. The foot bath involved immersion of the knees, and the temperature of the water was maintained at 41°C. There were no significant changes in energy consumption after the foot bath, and no significant changes in heart rate, tympanic temperature, and blood pressure. Therefore, our results suggested that there were no significant energy metabolism changes after 30 min of foot bathing at 41°C.
