Could red light therapy support fertility, postpartum recovery, period pain, menopause, and other important areas of women’s health?
In this episode of Alex Fergus – Light Therapy Insiders, Bart speaks with midwife and women’s health specialist Tracy Donegan about the emerging use of photobiomodulation for female reproductive health.
They explore the research, Tracy’s clinical experience, the devices she uses, and why targeted protocols matter. The conversation also covers male fertility, pregnancy precautions, C-section recovery, breastfeeding discomfort, pelvic pain, menopause, circadian health, and how long it may take to notice results.
Show Notes
Women have historically been underrepresented in medical research, and photobiomodulation is no exception. Although research into red light therapy for women’s health continues to grow, many questions remain unanswered.
Tracy explains how she uses targeted red light and laser therapy in her work with women experiencing fertility challenges, postpartum wounds, pelvic pain, menopausal symptoms, painful periods, and other intimate health concerns.
She also discusses why treatment must be individualized. The correct device, wavelength, dose, treatment location, and frequency can depend on the person and the condition being addressed. More power is not necessarily better—particularly when working around sensitive tissues or nerve pain.

Red light therapy has moved fast—from a fringe topic known only to researchers into a booming consumer industry. But according to Ari Whitten, much of the conversation has outpaced the science. In this episode of Light Therapy Insiders, Ari joins me, Bart Wolbers, to unpack how red and near-infrared light interact with human biology, why mitochondria are central to health and aging, and where common assumptions about dosing, heat, and device performance break down.
Ari is the author of The Ultimate Guide to Red Light Therapy, recently released in a fully revised and expanded edition, co-authored with Dr. Michael Hamblin—one of the most-cited photobiomodulation researchers in the world. This conversation goes well beyond surface-level benefits and dives into the mechanisms, controversies, and the reasons humility matters in a field that’s still evolving.
Show Notes
In this episode, Ari Whitten shares how his early work on mitochondria led him to red and near-infrared light years before the consumer market exploded. We discuss why photobiomodulation can’t be reduced to a single mechanism, why many device claims are misleading, and how an evolutionary view of sunlight helps explain its role in modern health.
This conversation is ideal for listeners who already know the basics of red light therapy and want a deeper, more nuanced understanding—without hype.
Key Topics Discussed
Ari Whitten’s journey into red light therapy
From competitive athletics and bodybuilding to chronic fatigue after Epstein–Barr virus infection, Ari explains how his focus shifted toward energy metabolism and mitochondrial health—and why that led him to light biology.
Why mitochondria are central to health and aging
We explore how modern research reframes mitochondria as more than “cellular powerhouses,” highlighting their role in immune function, brain health, stress responses, and biological aging.
Red and near-infrared light in an evolutionary context
Humans evolved under the sun, and different wavelengths influence biology in distinct ways—circadian rhythm signaling, vitamin D synthesis, nitric oxide production, heat effects, and more. Red and near-infrared light stand out because human tissue is unusually transparent to these wavelengths.
Moving beyond the cytochrome c oxidase story
Once considered the primary mechanism of photobiomodulation, cytochrome c oxidase is now understood as just one piece of a larger puzzle that includes gene expression, growth factors, immune signaling, and systemic effects.
Heat, dosing, and the biggest PBM controversies
We break down the debate around whether photobiomodulation must be “non-thermal,” why mild tissue warming is often unavoidable, and where the real danger thresholds likely sit.
Systemic vs localized effects
Ari explains why red light therapy doesn’t always need to be applied directly to a target tissue to produce benefits—and how blood, immune, and signaling pathways may play a larger role than many people assume.
Pods vs panels: Is the price difference justified?
We discuss whether full-body red-light pods offer advantages over large-panel setups—and why the lack of direct comparative studies leaves this question open.
Industry transparency and misleading specs
A strong call for third-party testing, honest irradiance data, and higher standards in an industry where exaggerated claims remain common.

Red light therapy can be a real performance tool — not just something you do for “recovery.” This video breaks down what the latest research on exercise performance says about muscle endurance, strength, fatigue, inflammation, and VO₂ max.
The key takeaway is simple: timing matters. Most of the best results show up when red light therapy is used before your workout (often a few hours beforehand), and current evidence still points toward local treatment (targeting the muscle you’re about to train) over full-body sessions for measurable performance outcomes. Interestingly, full-body setups may still help sleep quality, which can indirectly support training and recovery over time.
Bart also explains why some results look mixed (especially for running), why older laser-based protocols don’t always translate cleanly to consumer LED devices, and how to choose the right device and dosing approach for the muscle group you’re training.
This episode is part of a free, science-driven red light therapy course designed to help you understand the foundations, cut through hype, and apply light therapy more intelligently over time.

Worried that red light therapy could damage your eyes?
In this video, Bart Wolbers breaks down the real science behind red + near-infrared light and eye safety, including a conservative protocol (around 40–50 mW/cm²) and why that dose is tiny compared to what humans are exposed to outdoors. He also covers where blue light and UV fit in, what “safe exposure” really means, and practical tips if you’re using panels, tabletop devices, or handheld units near your face.
He also explains why more isn’t better, why too little can be a problem, and exactly how he arrived at my 40–50 mW/cm² eye protocol—a tiny dose compared to daily sunlight exposure, yet effective in studies.
