Trial Summary

What is the purpose of this trial?

The frequency and severity of heat waves has increased in the last decades. Older adults (over 65 years) have impaired responses to heat stress making them at increased risk for adverse events. Previous heat waves report that women over 65 experience worse health outcomes than any other age group and age matched men. Aging and reproductive hormones, specifically estrogen, independently alter responses to heat stress. However, the combined effects of low estrogen following menopause and aging on the response to heat stress are unknown. In this study, the investigators will identify the role of estrogen in pre and post menopausal women on thermoregulatory responses to heat stress.

Eligibility Criteria

This trial is for postmenopausal women over the age of 65 who are experiencing issues with body temperature regulation. Participants should not have any conditions that could interfere with hormone therapy or thermoregulation studies.

Participant Groups
2Treatment groups
Experimental Treatment
Group I: Premenopausal estrogen suppressionExperimental Treatment2 Interventions
Participants take a cellulose placebo tablet for 4 days prior to baseline testing and continue until experimental visits are complete. Following completion of placebo testing, participants begin taking 400 mg/day Elagolix for 4 days prior to testing and continue until experimental visits are complete.
Group II: Postmenopausal estrogen supplementationExperimental Treatment2 Interventions
Participants wear a transdermal estradiol patch or placebo patch for 5 days prior to testing and continue until experimental visits are complete. After 48 hr washout, participants then wear the alternative treatment for 5 days prior to testing until experimental visits are complete.
