Mouth Tape Sleep Trend Has Caused Deaths According to Meta-Analysis Study
"People have died using mouth tape. There was a meta-analysis that was released last year looking at 20 different studies. People have died using mouth tape. And here's the thing, because people are not seeing if they have undiagnosed sleep apnea. If you've got undiagnosed sleep apnea and you tape your mouth shut, it's not a good idea."
About this episode
On this episode of The School of Greatness, host Lewis Howes interviewed Dr. Michael Breus, a clinical psychologist and sleep medicine specialist known as The Sleep Doctor, for an extensive conversation about sleep science, common misconceptions, and practical interventions. Breus, who has treated patients for decades and authored multiple bestselling books including The Power of When, distinguished himself as a sleep doctor rather than sleep expert, explaining he pressure-tests academic theories in real-world conditions. The conversation opened with a provocative claim that the human brain is more powerful than any pharmaceutical intervention, with Breus demonstrating that fear can completely override drugs like Ambien. He then systematically challenged popular sleep trends, calling mouth taping the second stupidest sleep idea and revealing that a meta-analysis documented deaths from the practice among people with undiagnosed sleep apnea. Breus introduced his chronotype system dividing people into lions, bears, wolves, and dolphins based on genetic sleep patterns visible in the PER3 gene, arguing that 85% of the population cannot wake at 5 AM and that The 5 AM Club sets people up for failure. He explained that chronotypes determine optimal timing for everything from sex to creative work to eating, revealing that 75% of couples have sex at the worst possible time hormonally. The episode covered actionable protocols including a five-step nightly routine, the Napa Latte technique combining coffee and 25-minute naps, 4-7-8 breathing to lower heart rate below 60, and why one consistent wake time matters more than bedtime. Breus also shared findings that cancer treatment timing relative to circadian rhythm affects chemotherapy efficacy, that entrepreneurs wake differently than employees, and that sleeping next to a snoring partner costs one hour of sleep nightly. Throughout, he emphasized that sleep affects every organ system and disease state, calling it the volume knob for greatness.
Key takeaways
- Breus revealed that fear can completely override pharmaceutical sleep aids like Ambien because the brain is more powerful than any drug.
- A meta-analysis of 20 studies documented deaths from mouth taping, particularly among people with undiagnosed sleep apnea, making it potentially lethal.
- Research shows administering chemotherapy at specific points in a patient's circadian rhythm requires less chemo and produces better treatment outcomes.
- 85% of people are genetically incapable of waking at 5 AM due to chronotype variations in the PER3 gene area.
- 75% of couples have sex between 10:30 and 11:30 PM when their hormone profiles are opposite of what's needed for optimal sexual performance.
- The 5-step protocol includes one consistent wake time, stopping caffeine by 2 PM, stopping alcohol 3 hours before bed, stopping exercise 4 hours before bed, and morning sunlight exposure.
- Sleeping next to a snoring partner causes approximately one hour of sleep loss per night according to research data.
