What is the most common symptom of menopause experienced by 75% of women at some point? Hot flashes. This pesky problem is attributed to estrogen withdrawal. During the menopausal transition, hot flashes are associated with a rise in the body’s core temperature and a narrowing of the body’s thermo-neutral zone, with a decrease of the sweating threshold and an increase of the shivering threshold. Simply put, peri- and menopausal women tend to run a bit warmer than pre-menopausal women with an increased tolerance for cold and a decreased tolerance for heat. These changes in the body’s temperature regulation are associated with multiple fluctuations in hormones and the neurotransmitters that accompany menopause, including changes in estrogen, norepinephrine and serotonin.
