| Outline of Final Research Achievements |
No sex differences in sweating ability were observed in prepubertal children. After puberty the ability increased in both sexes, but the increase was smaller in females than in males. The resulting sex difference in sweating ability decreased with aging and tended to disappear in people in their 80s. Sex differences (males > females) were also observed in the degree of improvement in sweating ability by short-term physical training and heat acclimation. The degree of improvement by long-term physical training was smaller in prepubertal children and elderly people than in younger adults. Biologically, the lower sweating ability of females may represent an attempt to control body fluid loss by reducing the amount of excess sweat that drips from the body in a hot, humid environment. Modification of sweating ability by long-term physical training, heat acclimatization and aging in males did not involve sex or growth hormones.
