First I love your videos your English has improved so much, loved your book 📖 keep up the good work
Thanks! Would appreciate a supporting review on Amazon
@@SiimLand I hope you sold enough. Maybe ask companies to promote it?
For something as dangerous as sleeping in evolutionary terms, I’d be shocked if any parts of our sleep weren’t crucial. I don’t imagine natural selection somehow allowing us a few hours of unconsciousness with no benefit
Matthew walker second this. Sadly that our society does not optimize and value sleep
Tbf natural selection doesn’t care about longevity for the most part, it could help reproductive success while not mattering much for lifespan.
The benefit is not having to sleep again for the next 16 hours.
But if you allow regular naps throughout the day, it makes sense that it would work different.
Damn! I did that too in university for 6 months 😂 even tried the Uberman for a week (the craziest, like a never ending day feeling)
What’s the uberman please explain
@@gqas1247 2 hours sleep per day. 20 mins nap every 4 hours.
@@gqas1247Uberman sleep cycle: The Uberman schedule is one of the most extreme forms of polyphasic sleep. It involves six short naps, each lasting about 20 minutes, spread evenly throughout your day. It totals only 2 hours of sleep in a 24–hour period. This schedule requires strict adherence to nap times to work effectively. It’s often chosen by those who want to maximize their awake time, but its intensity and discipline make it a challenging schedule to maintain.
If I sleep more than 4-5 hours a night, I can’t fall asleep the next day. I have to wake up at 4am everyday, otherwise my sleep the next night is almost non existent.
good for you
one of your best videos ever imo
Im doing sort of this for work 4-5 hours and one or two naps, glad to see that it’s not that bad
Very interesting. I think alot of college students do this without realizing i.e. due to cramming for exams and papers ……
Margaret Thatcher (UK) slept 4-hours per night without any naps.
And how did you lean down your face that much??
He eats very low calories and IF 20:4 window.
Genetics, i could get fat af and my face still looks leaner. Its just different for different people
He reduced his visceral fat significantly, that’s reflected on the face.
I’m not great with naps as I’m a night person and will end up sleeping too long in the daytime
Great video, Siim! Your exploration of polyphasic sleeping is fascinating and raises important questions about sleep quality versus quantity. As a fellow health YouTuber, I appreciate how you highlighted the impact on cognitive performance while also addressing the potential downsides of such a drastic sleep schedule.
Research shows that while some individuals may adapt to polyphasic sleep, the majority of us thrive on the recommended 7-9 hours of sleep for optimal health and cognitive function. The importance of REM and deep sleep stages cannot be overstated, as they play crucial roles in memory consolidation and overall well-being.
Dr. Greg Potter’s insights add a valuable scientific perspective, especially regarding the circadian rhythms that govern our sleep patterns. For anyone considering this approach, I’d recommend monitoring how you feel both physically and mentally, as individual responses can vary significantly.
Looking forward to more content like this! Also, congrats on your new book—can’t wait to check it out!
There are a couple genetic variants where they need less sleep and are perfectly refreshed after a few hours. I am really curious if they live shorter lives or just as long. I hope someone does a study. I don’t think these are very common. I would also be curious if their glymphatic system is just more effective.
It would be a great target of genetic modification, if it does not have any downsides. It would be like getting 12–15 more years for free. Just fit in the same 75–85 or so years.
If everyone had the modification, though, they might increase the work hours.
In a related thought. I think it is very sad that so many people have commutes to work and back that take so much time, squandering years of their lives. And the time is often taken from quality time with their children.
Sounds extremely unhealthy
I feel crap with more than 7h sleep. 4-5 h I feel the best.
uberman sleep schedule? I tried this when younger and it was brutally hard to adhere to
Thank you for these experiments!
Iv been watching a long time but not as far back as 2017.
The Eastern culture and ancient scriptures forbid day sleeping . Only the unhealthy, infants and 60+ are exception. I’ll rather sleep 4 hours at night and do not sleep in the day
I did mostly polyphasic or siesta sleep for the past forty years. Now, based on prevailing research and career change I have pushed myself to 5-6 hours a night. Cognitive performance seems to be easier, but mostly fear of falling asleep well driving necessitated the change. Five years later still struggle to sleep that long.
