Red light therapy & Photobiomodulation, w/ Tracy Donegan

from The Natural Womanhood Podcast · host Grace Emily Stark

By now, many of us have seen the Instagram reel of the woman absolutely terrifying her kids by coming around the corner with a red light therapy mask on her face. If your reaction was also to jump and think something along the lines of "What the heck could that possibly be for?!", then this episode of The Natural Womanhood Podcast is for you. As it turns out—and as we learned from interviewing midwife, doula, and red light therapy expert Tracy Donegan in this episode—red light therapy is about so much more than gimmicky face masks, and it has a surprising amount of data to back it up, especially for women's health and fertility.  Better known as "photobiomodulation" (PBM for short) in the scientific literature, the science of light therapy has everything to do with how much our mitochondria love sunlight—and how little of it they get nowadays. And don't worry, if all you remember about mitochondria is that they're "the powerhouse of the cell!" Tracy explains the science of PBM in a way that's clear, convincing, and—best of all—actionable (and, spoiler alert, you don't need a fancy laser to take advantage of many of the benefits of red light—just more time outside, and less time under artificial lights staring at screens). You don't want to miss this timely, fascinating episode of The Natural Womanhood Podcast.
