Level 5 - mechanism / opinion, no new human data
Narrative review of preclinical rodent mechanistic studies with no primary human data.

What was done
This narrative review summarizes preclinical findings from rodent studies examining the neural and molecular targets of estrogens within brain regions that control temperature homeostasis.
What was found
The abstract reports no numerical data or statistical findings. It describes that estrogens modulate distinct specialized neural circuits and molecular targets in rodent brain areas controlling temperature regulation.
Why it matters
Understanding the exact neural circuits through which estrogens affect thermoregulation may enable the development of targeted therapies for menopausal hot flashes and night sweats without the health risks of systemic hormone therapy.
Limits
Findings are based on animal (rodent) models rather than human clinical data. The abstract does not specify the number of reviewed studies, specific brain circuits, or quantitative effect sizes.
