I slept from 8-10 pm, getting 90 min of brain restorative deep sleep; back in bed at 3 am to get 6 more hours.
The evidence is convergent. Multiple independent sources reach the same conclusion, the underlying mechanism is well-characterized, and even the field's most cautious voices treat it as worth doing.

Every Sunday: the week’s new conflicts and verdict changes — and nothing else.
Native comments, Twitter mentions, and Reddit threads about this claim — surfaced together so the conversation isn't fragmented across platforms.
Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.

All my sleep hygiene practices are aimed at lowering my RHR.
I'll fall asleep within 2 minutes and get around 2 hours of deep and 2 hours of REM.

Over the past few weeks I’ve worked to systematically optimize my sleep and have experienced significant gains, ranging from a 40% to 157% increase in deep sleep!
it's why I go to bed at exactly the same time every night it's why my sleep is so structured because I want to feel wonderful I want my head to be clear I don't ever want to be sick
my sleep is uh spectacular I mean I've you know having three young kids and always being an entrepreneur my whole life has been like a fair share of stress and turmoil and difficulty and so sleep has always been something challenging for me uh and now it's just um I love it it's one of my favorite things I do changes how I understand and feel about life
so my body I have a low resting heart rate
but I really have dialed this in over two years it's a system and I get a high quality sleep every single night
in the past seven days I've had seven perfect nights of sleep performance 100 I was in a 99.2 percentile for Sleep performance
ironically why I go to bed at exactly the same time every night it's why my sleep is so structured because I want to feel wonderful I want my head to be clear I don't ever want to be sick
So, your goal this week tangibly is sleep, right? Uh sleep every day and you're go What are the specifics? You have a bedtime. Yeah. Yeah, I'm pushing my bedtime back to 9:30 and I'm just going to allow my body to wake up when it needs to. Okay. And what is your uh what is your uh grace zone? 9:30 plus or minus what? 5 minutes. Plus or minus 10 I'm going to say.

nothing is more important in life to meet and sleep if sleep is Right life is right
my sleep is in the 99th percentile of whoop users whoop is a wearable that I have here of people my age

I like to think of myself just like I like the idea of I'm a professional Rejuvenation athlete I like to think I'm a professional sleeper and I behave that way and uh it's my number one priority in life because I am a creature that is subject to my biochemical States
because we measure so much I've developed intuitions of awareness I didn't have before so often times I can feel my body temperature I know my heart rate almost at all times I can feel things with greater Sensitivity I can wake up in the morning and I know what my sleep state is I I can feel how much deep I got and how much Rim I got
when I spoke with whoop on their podcast they pulled some data for people my chronological age and I was in the 99.4 percentile for Sleep performance
recently shared I achieved 30 days of 100% sleep performance this is according to my wearable whoop
Nighttime Bryan now reliably gets restorative sleep, and morning Bryan is always well-rested and ready for the day.
last year I started acquiring data on myself with a combination of brain scans and wearables that gave pretty compelling evidence that a key aspect of my impulse control is strongly determined by the amount of deep and Total Sleep the night before
I had eight eight months of perfect sleep using the whoop device now no human in history has ever done that not to say others couldn't I just did it when not others didn't but I wanted to demonstrate you can get predictably high quality sleep
I completed 6 months of perfect sleep
on any given night I will average over 2 hours of Rim 2 hours of deep and I will be up less than 30 minutes a night these are the markers of exceptional sleep
I know from achieving the best sleep score in human history 8 months of perfect sleep that the single strongest predictor of my nighttime Sleep Quality is my resting heart rate everything I do is to lower the beats per minute of my heart the lower I go the better my sleep
the single strongest predictor of my nighttime Sleep Quality is my resting heart rate
everything I do is to lower the beats per minute of my heart the lower I go the better my sleep
at 8:30 my head will hit the pillow and I will be asleep within 1 to 3 minutes on any given night
and I will be up less than 30 minutes a night
these are the markers of exceptional sleep
I will average over 2 hours of Rim 2 hours of deep
The other metrics uh Luke did an analysis for me and I'm on some of the metrics I forget I don't have the data in front of me now but it was like in the 90th 98th 99th percentile in some areas. I forget the actual numbers but yeah uh definitely it's elite level sleep performance.
I do remember that my the number of wake events that I had was you know three four five six whereas now my number of wake events that I actually can remember is uh zero to one so substantially it's I mean I think I oddly at age 47 am getting the best sleep of my life legitimately
my sleep depends upon my resting heart rate before bed. And so I've tried to structure my entire life around this idea of things that increase my resting heart rate are bad. You know, of course, excluding exercise, like that's a different topic. Things that lower my resting heart rate are good.
Also the biggest thing I did on this trip is I incorporated naps. They were absolutely gamechanging. So, uh, yeah, like, so I would I was able to sneak in like a 60 minute naps. Um, so longer than 20 minutes. And if if my sleep data was correct, I was out in like one minute and I was getting something like, you know, 52 minutes of deep sleep. My body was just craving sleep. So, I had the incredibly sound sleep. I'd wake up after that postnap.
10 minutes of bright outdoor light within the first hour of waking anchors the circadian phase and improves sleep onset that night.
Morning sunlight exposure shifts the cortisol awakening response forward, improving daytime alertness.
Long-term morning sunlight reduces age-related macular degeneration risk.
Sleep regularity predicts all-cause mortality more strongly than sleep duration.
Tracking deep sleep on a wearable accurately reflects EEG-measured slow-wave sleep.
Caffeine has a half-life long enough that consumption after 2pm measurably degrades deep sleep in slow metabolizers.
