Scholarcy highlights

  • Most menopausal hot flashes are preceded by small elevations in core body temperature
  • If the thermoneutral zone between the thresholds for sweating and shivering is reduced in women with symptoms, the triggering mechanism for hot flashes could be explained
  • Study Design: We studied 12 postmenopausal women with symptoms and 8 without symptoms
  • Sweat rates were significantly higher among the women with symptoms than among the women without symptoms
  • Menopausal hot flashes in women with symptoms may be triggered by small elevations in body temperature acting within a reduced thermoneutral zone.
