6 Things Wrecking Your Recovery, Sleep & HRV (According to Millions of Data Points) | Dr. Kristen Holmes

Could improving your health be less about doing more—and more about recovering better? What if one of the biggest predictors of your future health isn't your latest workout or diet... but how well your body recovers from stress?

In this episode of The BeingBrigid Show, Brigid sits down with Dr. Kristen Holmes, Global Head Scientist at WHOOP and author of Aligned, to unpack what millions of data points reveal about recovery, heart rate variability (HRV), sleep, stress, and longevity. Together they explore practical habits that can improve recovery, support hormone health, optimize blood sugar, and help women navigate perimenopause and menopause with greater resilience.

If you've ever wondered why you're exhausted despite eating well, why your blood sugar seems harder to control under stress, or how to actually improve your HRV, this episode is full of science-backed answers you can start using today.
