What causes hot flashes?

by Margery Gass | Jan 10, 2013
Researchers have made new discoveries about how hot flashes happen:

A group of brain cells called KNDy (“candy”) neurons are probably the control switch for hot flashes. KNDy neurons respond to estrogen. When estrogen gets too low, these brain cells make more of a brain chemical (neurotransmitter) that signals the body that it is too hot. The body then releases heat by opening blood vessels to the skin that cause flushing and sweating as a cooling method.

Hot flash sufferers, take note: these insights will eventually help scientists create new and safer treatments for menopausal hot flashes. And that’s cool news.
