@sherijohnsoncoaching: If you're over 40 and waking up in a sweat, you don't have an estrogen problem, you have a cortisol problem. Cortisol affects your body's thermostat. and it spikes higher without the estrogen buffer you've had all your life. So as estrogen fluctuates and declines in perimenopause, cortisol spikes, you get hot flashes and night sweats. if you want to fix it, worry about balancing your cortisol first. if you want to know how, comment below and I'll answer your question! #hotflashes #menopause #nightsweats
