What this Trial Is About

The overall objective of this study is to examine the physiological responses that occur during a hot flush in postmenopausal women. The following specific aims will be executed to reach the overall objective of this study. Aim 1: To determine if hot flushes can be reliably induced with a temperature-controlled, water- circulating (TCWC) heating pad. Based on previous research, the investigators hypothesize that hot flushes will be inducible with the TCWC in symptomatic women, but not in asymptomatic women. Aim 2: To determine if heat-induced hot flushes in symptomatic women will cause reproducible cardiovascular and respiratory responses. The investigators hypothesize that heat-induced hot flushes produce similar and reproducible cardiovascular and respiratory responses to spontaneous hot flushes. Aim 3: To determine if body fat percentage influences hot flush severity or frequency during spontaneous or induced hot flushes. The investigators hypothesize that women with higher body fat have reduced hot flash severity and frequency.
