In this episode of unPAUSED, Dr. Mary Claire Haver sits down with Dr. Kristen Holmes, Vice President of Performance Science at Whoop and author of the new book Aligned, to unpack why sleep and circadian rhythm matter as much as hormones when it comes to the symptoms women feel in perimenopause and menopause. Dr. Holmes explains the concept of circadian amplitude, the contrast between activity and rest, light and dark, and fed and fasted states that keeps every system in the body running on time, and why women with lower amplitude tend to report more frequent and more severe symptoms. She walks through why morning light exposure is one of the most powerful and underused tools available, how getting outside within the first part of the day sets the timing for melatonin release that night, and why a window is not a substitute for actual daylight.
