Menopause Hot FlashesNCT07824648
Thermoregulatory Physiology of Menopausal Hot Flashes
A study testing Intervention C (Targeted skin cooling), Intervention B (Ambient cooling) and Intervention A (Room temperature) in people with Menopause Hot Flashes, run by SRI International at 1 site in United States.
Trial summary
This study is evaluating the effects of cooling on menopausal hot flashes in midlife women. Precise targeted cooling is provided to areas of the skin when a hot flash occurs. Read more about this study
