Physiology of hot flashes
Open accessAbstract
Hot flashes are the most common symptom of the climacteric, although prevalence estimates are lower in some rural and non-Western areas. The symptoms are characteristic of a heat-dissipation response and consist of sweating on the face, neck, and chest, as well as peripheral vasodilation. Although hot flashes clearly accompany the estrogen withdrawal at menopause, estrogen alone is not responsible since levels do not differ between symptomatic and asymptomatic women. Until recently it was thought that hot flashes were triggered by a sudden, downward resetting of the hypothalamic setpoint, since there was no evidence of increased core body temperature. Evidence obtained using a rapidly responding ingested telemetry pill indicates that the thermoneutral zone, within which sweating, peripheral vasodilation, and shivering do not occur, is virtually nonexistent in symptomatic women but normal (about 0.4 degrees C) in asymptomatic women. The results suggest that small temperature elevations preceding hot flashes acting within a reduced thermoneutral zone constitute the triggering mechanism. Central sympathetic activation is also elevated in symptomatic women which, in animal studies, reduces the thermoneutral zone. Clonidine reduces central sympathetic activation, widens the thermoneutral zone, and ameliorates hot flashes. Estrogen virtually eliminates hot flashes but its mechanism of action is not known.

In the citing paper
“Based on published norms,10–13 hot flashes were flagged if there was an increase in sternal skin conductance of at least 2 μmho within a 30 second period, with a 15-minute post-event lock-out. Each skin conductance track was evaluated by a trained expert, verifying that each skin conductance event matched published norms for vasomotor events.”

“Hot flushes are characterized by a transient and intense sensation of heat accompanied by the activation of heat-loss effectors including skin vasodilatation, sweating, and cold-seeking behavior (Fig. 3) (Freedman, 2001; Kronenberg, 2010).”

“After a hot flush is triggered, the core temperature drops (Fig. 3) (Freedman, 2001; Kronenberg, 1990; Molnar, 1975), as expected with the activation of heat dissipation effectors.”

“Conversely, raising the ambient temperature increases the frequency of flushes in symptomatic postmenopausal women, and this feature has been used to stimulate flushes in a laboratory setting (Freedman, 2001).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
