SIMULTANEOUS STUDY OF THE CONSTITUENTS OF THE SWEAT, URINE AND BLOOD, ALSO GASTRIC ACIDITY AND OTHER MANIFESTATIONS RESULTING FROM SWEATING

Abstract

Profuse sweating was provoked by moist heat (temp. 40-42 C.) generated by electric current, the subject being seated, 20-50 min. at a time, in the sweat cabinet with the head only protruding and arms and torso completely enclosed in a rather thick rubber dam jacket belted around the waist. The 54 subjects reported 3 times a wk., at 6:30, 8 and 10 o''clock respectively. There was a fairly good correlation between rise in body temp. and increase in blood concentration; in only 36 out of 320 experiments was there no concentration. Under the given conditions there was a fairly uniform decrease in CO2 combining power (160 out of 212 experiments) and rise in blood pH (110 out of 134 observations). Further evidence is offered that the rise of body temp. provokes greater ventilation and thereby increases the blood pH.
