Podcast: Her Time, Her Health with Dr. Jila
Published On: Wed Sep 30 2026
Description: This week on Her Time, Her Health, I'm joined by Dr. Andrea Matsumura, a double board-certified sleep medicine physician, nationally recognized expert in sleep and menopause, creator of the Dream Sleep Method, and chief of sleep services at Monarch MD. Her work has been featured in The New York Times and CNN. We unpack why so many women who "used to be great sleepers" suddenly find themselves wide awake at 2 or 3am — and why the answer is rarely as simple as "just menopause." Dr. Matsumura breaks down the staggering rates of undiagnosed sleep apnea in midlife women, why the tools used to screen for it were built for men's physiology, the truth about melatonin and supplements, and her practical, five-part Dream Sleep Method for reclaiming real rest. In this episode we cover: Why so many women wake up in the middle of the night in midlife How estrogen and progesterone loss disrupts melatonin, oxygenation, and ventilation The "sleep syndrome of menopause" and its four telltale patterns Why 45–65% of midlife women may have sleep apnea — and 9 out of 10 don't know it Why women's sleep apnea and snoring look nothing like the male stereotype Restless leg syndrome, ferritin levels, and the new numbers to ask for Supplements, melatonin, and prescription sleep aids: what actually helps The Dream Sleep Method: habits, environment, emotions, archetype, and medical conditions Alcohol's real effect on REM sleep Sleep trackers (Oura, Whoop) — useful tool or obsession trap?
