Very timely video, as I always try to get 7 to 8 hours of sleep a night along side my keto and fasting lifestyle. This morning, I woke up after 6 hours of sleep, and couldn’t fall back asleep. Decided to get up and see how my day goes on just 6 hours. I imagine I’ll feel fine, as I generally get the recommended 7 – 8 hours, while minimizing blue light exposure after sun down. Excited to watch your videos, as always.
If it’s 6hrs of deep sleep, you will not feel the difference. It may take a few sleep cycles for your body to adjust.
If you wake up ready to go, no need to lay back down. If you wake up tired, and you have some time, snooze for a little bit. Listen to your body. I figure the average human needs at least six to seven hours per day. And it’s best to do it all at once that way you remain in REM sleep as long as possible.
I naturally do well on 4hrs monofasic sleep if im not doing much excercise (my sleep cycle is 1hr20min). Long ago there were times when i used to over excercise almost daily and sometimes excercise beyond all possible limits 😂 at that time i slept normally 6-8hrs.
Thanks for covering an important topic and sharing your experience!
Thanks for watching
I’ve been working for over 30 years and for the most part sleep well with a few exceptions but now that I’m retired I find that a nap after a workout and not having to work effects how long I sleep at night.
I’ve tried this as well. Sometimes id start dreaming very vividly so quickly that it would startle me and wake me up. Now I prefer at least 6 hours with qigong and meditation or around 7.5 hours for best performance. While I was new parent of twins I barely slept for 6 months and it took me nearly a year to feel right again.
You barely slept but was it quality sleep?
@Brassic i guess. 🤷♂️ never felt right. Seriously start to feel like reality gets a little slippery if you don’t sleep enough. Everyone is different though some people just don’t seem that affected.
The effects on protein synthesis and the quantity of rna/dna encoding errors is not being measured here.
This type of study has been done often but I’d love to see the overall results taking sleep deprivation effects on epigenetics.
Interesting, but it sounds horrible, not just the feeling, but one of the few things that it seems everyone in this space agrees on, and for myriad reasons, is the importance of good deep sleep. That said, this experiment would be doubly interesting if you had that Oura in college 🙂
One thing i notice about polyphasic sleeping is that everyone always talks about geniuses like Nikola Tesla, but they leave out the part about how many of the people who practiced polyphasic sleeping had some serious mental health issues.
Yeah, Zakk is correct, those “genius” type dudes also did alot of BLOW!! That’ll keep you from sleeping🤤😯😳😇
I’ve been doing it for over 20 years now and my mental health is completely fine? It depends on the person and not everyone can handle this type f=of lifestyle.
@vih. what does f=of mean?
@Siddhant Kumar I meant to type on of**
Thank you, Siim- for sharing these findings and for your valuable advice. May you continue to grow, learn, and prosper. Bonnie
As I recall from my “adventureracing days” the best optimal sleep pattern would be when the body temperature is at it´s lowest. If I recall right it was around 2 am, 10 am and 8 pm. So 3 (or was it 4?) 20-30min naps during racing would be a minimum optimal “enough” . But that is maybe during a week of really tough workout and then maybe 2 months of recovery..! 🙂
I can do polyphasic sleep, as long as I’m a situation of low-stress and no schedule. But this only happens on extended stay-at-home vacations. After a couple of weeks away from work, I feel relaxed and refreshed enough to go with fewer long periods of sleep.
You may want to look into using meditation as a replacement for some of your sleep time. It is known that very experienced meditators sleep less. I have read about one person who spent hours a day in deep states of meditation, (probably in delta) only slept 1-2 hours a day.
I slept for 4 hours and 30 mins and woke up, couldn’t fall asleep. I just couldn’t, so I stayed up the entire day without rest studying for 10 hours. No sleepiness, no headache, and unbelievable focus and energy to keep studying.
You won the genetic loterry..
Since I started polyphasic sleeping, It becomes easier to lucid dream.
2hours a day?
I sleep for total of 6 hours a day. 4 1/2 at night, and 3 30 minutes nap throughout the day.
@John Mathew Rosario so basically segmented?
Yes, essentially. Polyphasic just means having 2 or more segment of sleeping schedule for the whole day.
@Max wait me too. I have very intense dreams now
With polyphasic sleep would it make sense to extend your naps on the weekends to 90 minutes instead of 30? Im asking this because on the weekends you have the whole day to yourself anyways so why not take the days off to fully relax your body and feel amazing for the weekend and the weekdays.
My polyphasic sleep idea: 4.5 hour core sleep and 3-6 20minute naps. This polyphasic sleep schedule is designed to have you sleeping for longer and experience the difference sleep stages a couple times but still reducing your sleep time through the use of naps. With this schedule you would be sleeping for 5.5 to 6.5 hours a day.
Note: this sleep schedule was one I just made up with very little knowledge about sleep and well still healthier then many other polyphasic schedules please do research before deciding to pick this schedule.
Absolutely good content. Thank you, Siim.
Question – with the naps, falling asleep wouldn’t be a problem for me but how to you ensure you actually really wake up and stay up after 25 mins?
alarm exists????then after some days your body will adapt in a way that u will not need any alarm ..
I’ve been doing Every Man 2 (4.5hrs plus two 20min naps) for over two years now and it’s great! I can’t imagine going back to monophasic.
What do you do for a living?
@144KGD Sorry I didn’t see this earlier, I’m self employed such that I can work when I choose, even if that’s at 3am and I don’t have have kids, so that makes it easier.
Are you still following this sleep pattern? And if yes, also mention any pros and cons you came across. Thanks in advance 🙂
@Lisa Kutiyal Yes Lisa, I am. It suits me very well, but I always had difficulty staying asleep for long periods of time. The biggest pro of course is all the extra time I have. Not just simply more time, but time when the rest of my world is asleep. It’s my favorite time for creative projects. The biggest con I think is my sleep time is vulnerable. Because I’m running my needs so thin, any interruption of a nap or core sleep can greatly disrupt my day. I’ve found my midday nap needs to be treated like some kind of secret mission with an undisclosed location to make sure I’m not interrupted.😊
@BrocknSpectre You are inspiring, I’d like to do this, I am starting with Everyman 1, 6 hour core at 12pm and 20 minute nap at 2pm, how long should I be able to do this without issues before I can try what you’re doing?
I think there is a strong correlation with memory & polyphasic sleep. There should be more studies in education performance with naps shortly prior & after attendance. Early childhood utilities lots of naps & almost all hunter & gatherer species use polyphasic sleep for recovery. There’s a trend happening with athletes optimising polyphasic sleep between workout sessions focusing on extended recovery instead of wakefulness.
I sleep 6-7 hours most days, sometimes 8 hours, sometimes 9 hours but also sometimes 4 hours. I feel more energetic with 4, 6 or 8 hours of sleep. I can sometimes have a sleepless night and then a 2 hour afternoon nap and regular sleep the following night and do fine. With me been a very creative person sometimes my sleep is limited.
