WHAT IT’S REALLY ABOUT
Sleep apnea, modern sleep threats, and performance-driven health strategies explained
- Sleep apnea is widespread, frequently missed (especially in women), and can harm health even when you don’t fully wake up, so screening and diagnosis should come before “optimizing” sleep.
- Modern environments—brighter nights, urban noise, novelty-driven screens, travel, and shared beds—are key reasons sleep quality is worsening despite a booming sleep-product industry.
- Wearables are useful for awareness and trend-spotting (e.g., total sleep time and resting heart rate patterns) but are unreliable for precise sleep-stage scoring and can fuel health anxiety.
- Galpin recommends running simple self-experiments to identify personal constraints (light, sound, temperature, arousal, fueling, stress) and building “sleep resilience” rather than elaborate bedtime routines.
- Energy, training progress, and body composition improve most reliably through focused constraint-removal (sleep, stress, nutrition, programming), progressive overload, and realistic, sustainable routines—sometimes complemented by targeted medicine when clinically needed.
IDEAS WORTH REMEMBERING
5 ideasTreat sleep disorders as medical issues before chasing optimization.
Galpin stresses that many people tinker with supplements and routines while an underlying clinical disorder (notably sleep apnea) is present; if disease exists, address it first because the health consequences are broad (mortality risk, mood, cognition, metabolic health).
Sleep apnea can harm you even if you don’t remember waking up.
Apnea is “stopping breathing at night,” and it doesn’t always cause a noticeable awakening—one reason it’s poorly diagnosed; loud snoring is a strong clue but not definitive.
Women’s sleep apnea is commonly missed due to stereotypes and reporting patterns.
Because apnea is culturally associated with larger men, symptoms in women are often attributed to hormones, cognitive load, or motherhood, leading to extremely high underdiagnosis rates.
Use validated questionnaires as the first, free step toward diagnosis.
For people without easy healthcare access, Galpin recommends short, scientifically validated screening tools (for apnea, insomnia, RLS, circadian issues, chronotype) before escalating to wearables or sleep-lab testing.
Wearables are best for trends and accountability—not REM/deep sleep precision.
They can reasonably estimate total sleep time and help identify patterns (e.g., resting HR links), but their sleep-stage scores and aggregate “sleep quality” ratings can mislead and increase anxiety.

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. So you're seeing an inverse. We're spending more on sleep, and sleep is getting worse.
