What causes menapausel hot flashes and what temp does it get?

Menopausal hot flashes are primarily caused by hormonal changes, particularly a decrease in estrogen levels, which affects the body's temperature regulation. This can lead to sudden feelings of warmth, often accompanied by sweating and flushing, usually starting in the chest and moving to the neck and face. The temperature during a hot flash can vary, but it typically raises the skin temperature by several degrees, often making individuals feel uncomfortably warm.
