TL;DR
Dr Andy Galpin reveals that 70–80% of people with clinical sleep apnea will never be diagnosed — and for women that figure rises to 90–95%. Even elite athletes aren't immune: roughly 50% have a clinical sleep disorder. The episode makes the case that most sleep advice is dangerously generic, and that precision diagnosis — starting with free validated questionnaires — is the necessary first step before any optimization.
Key Moments
Dr Andy Galpin
“Somewhere in the neighborhood of 70% to 80% of people who have clinical sleep apnea will go undiagnosed.”
Galpin is explaining why sleep apnea is the most dangerous and overlooked clinical sleep disorder affecting the general population.

“50%, depending on which study you look at, of athletes have a clinical sleep disorder.”
Galpin is pushing back on the assumption that sleep apnea only affects overweight or sedentary people, noting it is rampant even among the world's best athletes.

“For women, it's somewhere in the neighborhood of 90% to 95% of women that have clinical sleep apnea will go undiagnosed.”
Galpin is explaining why women are disproportionately missed in sleep apnea diagnoses, partly because symptoms are attributed to hormones or life demands.

“For every one drop in resting heart rate, so his resting heart rate, say went from 65 beats per minute to 64, he got six more minutes of sleep.”
Galpin is describing a real finding from 1,200 days of Oura Ring data for one client, showing how cardiovascular fitness improvements translated directly into longer sleep.

“Annual spend on sleep is like $600 billion right now, but yet we have seen a 60 minute drop in total sleep time over the last 60 years.”
Galpin is making the point that more money spent on sleep products has coincided with sleep actually getting worse across the population.

About Dr Andy Galpin
›
Dr Andy Galpin is a professor and human performance scientist whose PhD is in human bioenergetics. He founded his research lab in 2011 and has spent over 20 years working with elite athletes — including NFL linebackers, Olympic gold medalists, and world champion fighters — as well as executives and everyday people. He also coaches privately and runs several companies focused on enhancing human performance through physiology-first approaches.
Takeaways
1
Sleep apnea is massively underdiagnosed — especially in women 70–80% of people with clinical sleep apnea are never diagnosed. For women the figure is 90–95%, partly because symptoms are chalked up to hormones or life stress rather than anatomy. Galpin recommends starting with free, scientifically validated questionnaires as a first screening step before pursuing a wearable or sleep study.
2
Melatonin dosing is almost always too high Standard over-the-counter melatonin comes in 5–10mg doses, but Galpin's team typically uses 0.3–0.5mg — roughly a tenth of the norm. Outside of jet lag and circadian resets, he considers routine nightly melatonin use poorly supported by the evidence for most people.
3
Resting heart rate predicts sleep duration with surprising precision Across 1,200 days of Oura Ring data, one client gained six extra minutes of sleep for every single beat-per-minute drop in resting heart rate. This means improving cardiovascular fitness — not just sleep hygiene — can be a primary lever for getting more sleep.
4
Morning light exposure buffers against late-night light damage Getting adequate natural light in the morning doesn't just set your circadian clock — it actively reduces the negative impact of bright light exposure later in the evening. Galpin credits Andrew Huberman for being early on this finding, which goes beyond the standard 'avoid screens before bed' advice.
5
Sleeping to a podcast is a symptom, not a solution Galpin says using podcasts or TV to fall asleep is masking an unresolved cognitive downregulation problem rather than solving it. Switching to chamomile (apigenin) or magnesium addresses the same frontal cortex turnoff need without disrupting sleep architecture throughout the night.
6
Sleep apnea has multiple causes — generic treatment fails most patients CPAP machines and oral appliances have low success rates because they are issued generically regardless of whether the apnea is anatomical, neural, environmental, or positional. Galpin argues the field must move toward precision diagnosis matching treatment type to apnea subtype, including surgical options where relevant.

Urban light and sound alone are enough to meaningfully harm sleep NASA satellite data shows the world is measurably brighter than in previous decades due to sky glow — light from Earth bouncing back down from clouds. Urban baseline noise sits at 60–70 decibels at night versus the recommended maximum of 35, and studies link city living to 20%+ increases in anxiety and depression partly through these two factors.
