Eccrine sweat gland activity in heat acclimation

Abstract

The response of eccrine sweat glands of the forearms of four females was investigated during acclimation to heat. The sweat rate increased progressively during ten exposures. There was no significant change in the number of active sweat glands. The increased sweat rate could, therefore, be attributed to enhanced secretory activity of individual glands.

Zusammenfassung

Die Schweissdrüsenreaktion des Vorderarms von 4 Frauen wurde während der Akklimation an Hitze untersucht. Die Schweisssekretion stieg progressiv während 10 Sitzungen an. Eine signifikante Änderung in der Zahl der aktiven Schweissdrüsen wurde nicht beobachtet. Die gesteigerte Schweisssekretion beruht danach auf einer vermehrten Schweissbildung der einzelnen Drüsen.

Resume

On a étudié les réactions des glandes sudoripares de quatre femmes pendant la période d'acclimation à la chaleur. La sécrétion de sueur a augmenté progressivement durant 10 heures. On n'a cependant pas observé de modification sensible du nombre des glandes actives. L'augmentation de la sueur sécrétée provient donc d'une augmentation de la sécrétion de chacune des glandes en particulier.
