Science isnt sure what causes hot flashes and night sweats
during menopause—also known as VMS (Vasomotor Symptoms)
due to menopause. But it is known that VMS originates in
a part of your brain called the hypothalamus, which regulates your
body's temperature. It's here that specific neurons called KNDy
neurons play an important role in temperature control. To keep
your internal thermostat in check, your body relies on having a
balance between estrogen and a brain chemical called NKB.
During menopause, levels of estrogen and NKB become unbalanced.
This causes the KNDy neurons in your hypothalamus to tell your
body you're hot when you're not. To cool down, your hypothalamus
triggers hot flashes and night sweats.
