Artificial acclimatization of women to heat

Abstract

Acclimatization to heat, repeatedly demonstrated in male subjects, has not been reported in females. This paper presents quantitative evidence for heat acclimatization in women. Nine women participated (five at University of Pittsburgh and four at University of Illinois, Urbana) in daily 2-hr walks in the heat for 2–3 weeks. By the usual criteria (reduced pulse rate, reduced rectal temperature rise, lower skin temperature, ability to complete the assigned task, and subjective comfort) all subjects became acclimatized to heat.
