In this episode, host Dr. Yishan welcomes Dr. Nunez, a leading sleep health expert whose team has conducted one of the largest global sleep surveys — spanning 30,000+ participants across 13 countries over six consecutive years. Together, they unpack a paradox at the heart of modern sleep health: why is it that even as sleep awareness grows, most people still aren't taking action to improve their sleep?
Dr. Nunez shares eye-opening findings from the survey, revealing that while the majority of respondents recognize sleep's importance to long-term health, only about 26% have actually sought professional help for persistent sleep problems. The conversation dives into the real-world consequences of this awareness-action gap — from the rise of orthosomnia (an unhealthy obsession with sleep tracking data) to the dangers of relying on social media influencers for medical advice.
Together, Dr. Yishan and Dr. Nunez explore what healthy sleep actually looks like beyond the numbers, why sleep apnea remains a massively underdiagnosed condition affecting roughly one billion people worldwide, and why women's sleep health — particularly during pregnancy and menopause — deserves far more attention than it currently receives. They also discuss why cognitive behavioral therapy for insomnia (CBT-I) remains underused despite being a frontline treatment, and how simple sleep hygiene fundamentals — consistent timing, a cool and dark environment, and morning sunlight — can make a bigger difference than any trending "sleep hack."
If you've ever felt overwhelmed by conflicting sleep advice online, or wondered why knowing sleep matters hasn't actually helped you sleep better, this episode offers clarity, practical guidance, and the encouragement to take that next step.
