Monophasic sleep only works for me occasionally - that odd time when I’m exhausted and crash for a solid 8 hours or so. Mostly it’s 90min to 4 hour chunks at fairly odd hours.

You speak so fast. , diffucult to understand. Filipinos dont speak so fast.

So do we have to take all this on Faith, or are you going to cite any of your may claims

You seem extremely non open minded, yes there are downsides to polyphasic sleep, thats why most schedules have 'core' sleeps of often 1.5-3hrs and schedules such as the uberman are often not recommended. Do you research into the community before having such bias.

Dr Sophie Bostock, The Sleep Scientist, wanna collab it was really entertaining

Such a clear and helpful explanation!

Excellent overview - impressed by the clear structure and evidence based approach

it hasnt always worked 4 me mabe 1 out of 3

i been on mag bisglyncinate 3 days 200 mg a day, 1 out of 3 slept better the other 2 nights nothing 4 sleep! dont believe every thing tht ppl say about mag glyc

The study using magnesium oxide and finding little help for sleep is poorly done. Magnesium oxide is one of the worst absorbable supplements so why did they choose that instead of the better forms of magnesium? Thanks for mentioning the better forms briefly

Tart sour cherry juice plus melatonin= good night's sleep 💤😴 Works great for me 😁

I'm 68yr has brain surgery June 29.20023 jully I started have bad legs cramps and muscle.prombles talk to my doctor recommended magnesium citrate.also D3citrate

So far the best explanation I have ever heard. Supplements can be helped for a short short period but all we need is found en our planet earth. GOD es a wonderful make.

Can i take ZMA if i don’t have trouble sleeping?

😢😢😢😢NO MAGNESIUM FOR CKD 3B???

Told doctor i wasnt sleeping. She offered me a sleeping pill and another to wake up....never mentioned magnesium. I guess they don't get kickback from supplement companies.

How can you assist me tried several things some might work few nights and stop

I had an ongoing problem with sleep and my doctor prescribed a benzodiazepine which I took for 15 years. At first the medication helped, however in the long term I was still unable to sleep. When I changed to a new primary care physician he refused to prescribe the benzodiazepines. I read that magnesium glycinate might help me sleep, so I started taking 100 mg 3 times a day. Within days I had the best sleep of my life, and now one year later I am still sleeping like a baby, so whatever the studies say, for me it has been a miracle...

Magnezium give me more headaches I don’t understand ??Anybody else?

Magnesium glycinate changed my life. It's also the only form of magnesium I "feel." That molecule is doing something more than just increasing Mg serum levels because it actually helps with my sleep, RLS, and depression.

Did you try magnesium-threonate?

Can you do a video on l-theanine and other supplements for sleep?

More energy AND better sleep? A complete paradox 😅. And here i am watching this at 10:59 PM, hoping to fall asleep. Great video!!!

Brilliant video, well done Soph! x

thank you, gorgeous woman...

I have a question. Did the study focus on Uberman or/and some other more reasonable schedules like the Everyman series(E1 - 5-6 hour + 1 nap in the afternoon, E2 3-4 hours + one nap at around seven and one in the afternoon). Becuase Uberman is even in the polyphasic sleep community ty considered impossible to maintain and i have never seen anyone seriously advocating that soumeone should try it.

This is just propaganda for Big Sleep™, they want to keep us away from maximising our potential.

I just hate chats I guess I'm the only one that works

First 🎉

Another fantastic video Sophie :)

Volume is EXTREMELY low.

awesome video!

one cause of sleep reactivity could be kynurenine pathway disruption or inflammation.

Cicadian rythsm are not the same in everyone. Ever wondered why there are nightowls? They have a different type of rhythm. It was evolutionary beneficial for some to be naturally awake at night. They are also on average smarter than their daybird countparts.........maybe the night where you can't see needed them to relay more on their smarts. Anyways the point is that most people who sleep in polyphasic sleep are nightowls. It might in fact not be beter than sleeping once for a long time after you rhythm but those people are forced by society to sleep outside of theyre rhythm anyways. So polyphasic might joust be beter for them. Im not saying its imposible to work for daybirds but all the people i know it works for are nightowls. I personally can not sleep more than 5-6h because then i will feel like not having slept at all. During the day im constantly tired and nearly falling asleep but in the end im unable to properly sleep at night. My cognitiv abilities will be limited severly and reaction times can reach seconds If i sleep more than 8h. To a point where i walk in to things. I see it, i know i will walk in to it but the brain joust does not send the signal to stop. Like im a joust a passenger in my own body. It can create a cycle which can make me sleep for 16 - 18h a day. I sleep to much so im tired. I sleep some more and get even more tired......and the cycle goes on. Im now doing polyphasic sleep for around 8 years. Never started intentionally i joust wanted more free time and the only thing i could cut on my schedule was sleep. Though im not that consistent anymore as i know have a physically demanding job and often sleep 6 instead of the usual 3-4 i did before. When i have holidays where im joust at home i don't do polyphasic sleep and my sleep patern slowly shifts to sleeping at 04:00 and waking at 11:00 to 12:00 it allways hapens....this is my natural rhythm its way beter than polyphasic and i dont feel tired if i sleep longer than 6h but outside of holidays i wake up at 05:00 because im not a fan of starving and need to go to work. And polyphasic joust works beter in that case

This is the first video I watched about this topic that isn't just anecdotal evidence or "science doesn't know yet"

Hi Sophie, I really like your advice and have one question: If I feel sleepy, but sleep don’t come and I become awake again, what should I do? Will I repeat again and again? Thanks

I wanna do the uberman sleep schedule bc need more time to study

Night shifts have little in common with polyphasic sleeping. Polyphasic proponents say that their core sleep i.e a large chuck of three or four and a half hours, needs to be at night.

So what about a slightly shorter sleep and a siesta? If we need 8hrs sleep a night, would we need 6hrs and a 2hr nap or does any research suggest we could need less at say 6hrs and a 1hr nap?

Thank you 😊

2 hrs of rowing and 2 hrs of eating poop .. no thanks

Le risque avec le sommeil polyphasique c'est d'être en plein décalage horaire, comme en jet lag

I suspect that monophasic sleep pattern is a relatively NEW sleep pattern for humans. Why is a bi-Phasic sleep pattern more natural for a hunter-gatherer (pre-agriculture) society (i.e. tribe)? - Because they didn't have 4 things: 1) light bulbs 2) clocks (they didn't even have the word "hour") 3) houses to protect from predators 4) beds to sleep in "Why did we stop sleeping that way?" - Because now we have: 1) light bulbs 2) clocks (and the word "hour") 3) houses 4) beds, blankets and pillows Also, primitive tribes didn't need as much sleep because they didn't consume poison every day (sugar & salt / processed food). They also didn't eat meat every day (which requires more sleep time). Also, primitive tribes didn't need as much sleep because they didn't eat 3 to 6 times per day - because they didn't have: a) refrigerators b) restaurants c) grocery stores The proper way to study natural human sleep patterns is to observe primitive tribes that still exist today.

I’ve been doing the Every Man 2 cycle for over two years. I feel generally healthy, athletic, energetic and focused. Am I an exception?

So helpful! I love the analogy of an impending sense of danger vs reassuring ourselves we are safe. Thank you for this mindset shift

I see you are good sport, so I figured a response would just yield benefits.

1. Unsupported polyphasic schedules don't represent the entire community. 2. 7 to 8 hours is a monophasic recommendation and there are no studies supporting the idea of reducing polyphasic schedules being harmful in long-term. As long as personal NREM2, SWS and REM requirements are met, polyphasic sleep can be and is currently maintained by a community's member for 6 years and counting without health issues or physical performance regression. 3. Circadian rhythm is managed with the use of red laser protective glasses to filter out wavelengths (190-540 nm) that disrupt melatonin production 8-10 hours a day, though the other circadian cues, such as exercise, food, temperature etc. have to be counted in to improve sleep quality. 4. Uberman consists of 6 20-minute naps, as opposed to 30-minute naps on Dymaxion-like schedules which induce SWS wakes and have little viability in terms of common use. 5. Sleep deprivation is caused by moving the sleep blocks, an effect similar to moving monophasic sleep, and it takes time for the body to get used to the new consistent sleep times and repartition the sleep stages in case of a reducing schedule, which is supported by many viable EEG readings from the community's members.

Thank you for teasing apart the data. This video needs much wider attention - as per usual the media focus on the headline numbers in our declining culture
