Being able to sense time helps us do everything from waking and sleeping to knowing precisely when to catch a ball that’s hurtling towards us. And we owe all these abilities to an interconnected system of timekeepers in our brains. But how do they work? Marco A. Sotomayor details how human bodies naturally tell time.
Lesson by Marco A. Sotomayor, animation by TOGETHER.
My body knew that it was time for a ted ed video so I'm here early
Manan Adhvaryu actually first, congrats. extra points for not commenting completely irrelevantly
:)
You can't be "early" for a video. That would also require that there is something as "being on time" for the video and "being to late" for the video...
Hello.
DNA contains information on how to build an organism.Information only comes from an intelligence.
DNA is the book of life.A book requires an author.
Because
You subscribed and set the remider om
But how come when I take a long sleep in the afternoon I don't know what decade I'm in when I wake up.
Yh....right...i just woke up from my evening sleep 😅
Lmao when I don't sleep enough, my brain resets the clock to a random invalid date, or a date far into the past or future. This morning, it was set to 11 November 2030 lmao
One day 1 slept at 4:00 PM and woke up at 8:30 PM and thought it's 6:00 PM
Its 2020 know
😂😂😂
I don't know how he didn't get bored to death.
He was old, old people don't get bored
A Cat but, why?
Because they have enough to think about.
eatcarpet the things people do during experiments
+A Cat Lollll hahaha
Well, it's 2 a.m. and my body doesn't understand I need to go to sleep right now in order to function tomorrow..
my body also
cuz u have no brain!
MrWhiteman TV sit your ass down
.
Its cause our phones throw blue light into our eyes, making us think its day time
Edit: 3:30
As a person with ADHD, I can confirm I experience time differently than my peers and coworkers. I'm notorious for misjudging how long or short a task will take, and we have timers to help keep not only me on track, but to benefit all of us when we get into flow or distracted. Time is standardized, but it's experience is not standard.
What I find interesting is that most mornings, before I take a shower I start a timer for 13min20secs to tell me when to get out. Despite not having the same routine when I'm actually in the shower (taking more time washing my hair for example or simply enjoying the hot water) most of the time, I manage to leave the shower just a couple of seconds before the timer runs out. I get that intuition that it's time to get out and funnily enough, it is. That made me question the situation so I tried with different times like 15min or even 10 min and almost every time I managed to keep it really close to the set timer. I find it really fascinating.
This narrator's voice is so nice, could listen to him all day :)
I guess that explains why I ALWAYS wake up at 9 o'clock.
People always complain about waking up early on the weekend, but I think it is nice, Because that way you can enjoy many hours of free time :)
@@mrniceguy4277 tell that to me I WAKE UP AT 4-4:45
Daniele m Ouch
@HQDefault I wake up at 11 am lmao
I wake up late on the weekends lol
The reason why I like TED Ed is that it has the answers to almost all of my silly questions
This is why working from 9 P.m. to 6 A.m. fucks you up.
then in 8 hours work 2pm to 10pm then the next 8 hours work 6am to 2am
I've heard that what Matty Matt suggested is even worse than night shift by itself (there is no consistent 24-hour routine present, compared to a scenario in which there is one but it doesn't match well with the schedule that the body wants).
+Matty Matt You work in a factory.
Not so much a factory as a cannery
Brandon Miller This is why working from 10 am to midnight one week, then 5 am to 10 am, then 7 am to 8 pm will fuck with you too
What an amazing creation our bodies are!
right :)
Ted-ed vids always have epic - timeless - ending.
"CLK." Scientists are *so* creative. Reminds me of the time engineers named a programming language "A," and then the second version "B," and the final version "C."
We need more people like Siffre willing to put themselves through this stuff.
This video made me sleepy.
Chris Pfannenschmidt LMFAO
Me 2. 🌝🌝
'Only time will tell.'
Wow
[WUT] Dankiel gli made my day😂😂
Omg read read this at the exact time it said only time will tell 😂
These lessons can really change anyone's life!!
Either I have no circadian rhythm or it's extremely broken. None of this stuff happens for me.
I do not have this internal clock - I do not know when to eat or when to sleep - I gotta check the clock. And, I better do not mention catching the ball...
ME TOO! I do not know what time it is without looking at the clock and I CANNOT catch a ball. Thank goodness I still have time to try to fix my internal clock before I have to go move out
Honestly, my online classes are the only way I know what day and time it is. Otherwise I would sleep all day...
Me too
I used to work in radio and all of my breaks were programmed around (multiples of) 30 second advertisements. After a few months I would instinctively know how long 30 seconds was - down to about a second of accuracy. I could be totally engrossed in a conversation or surfing the web during an ad break when something in the back of my brain would say "time's up!" - and it was. That was a number of years ago and the 30 second timer has faded away but it was a fascinating phenomenon when it was around.
How did he record when he ate and slept if he had no clock.
TheNoerdy1221 Night camera? The one that records in dark...
according to wikipedia, he called his research assistants whenever he woke up/slept and ate...so they were the ones recording this information
TheNoerdy1221 I'm using Google Voice to type this comment
He had electrodes attached to himself that monitored when he slept and ate.. I can only assume it recorded those activities with date and time information.
Soulless leftover!
Did those exist in 1962?
I am addicted to these videos.. These days I can’t sleep without watching one of TED...
우리몸이 시간을 어떻게 인지하는지, 쉽게 말해서 시계가 없어서 정확한 시간을 모르지만 우리가 먹고 자는 우리의 생활 사이클이 어떻게 언제나 비슷한지에 대하여 배워보는 시간이 되었습니다. 좋은 시간이 되었습니다. 감사합니다.
I have a default alarm clock infused in my brain, so if I want to wake up super early for early work, I wake up naturally on the right time... how fabulous a creature I am.
"maybe time's just a construct of human perception
an illusion created by- MYAAAH MYAAAH MYAAAH MYAAAH MYAAAH MYAAAH MYAAAH MYAAAH MYAAAH MYAAAH MYAAAH MYAAAH MYAAAH MYAAAAAAAAAHHHHHHH"
Rippertear Don't hug me I'm scared.
Rippertear After watching this video, that statement has never been more correct
Time is a matter of space.
I hate myself for watching this kind of video late at night.
I believe each brain has its own clock, so we are different! but all our clocks' timing are very close ( night is sleeping and day is working ).
The problem is, today we have light everywhere and waves on our brains which change our timing from ppl back 1000years
Yeah .YOU are right 💜.
Why does watching tv or youtube right before bed makes me fall asleep faster?
Probably because you're straining your eyes, making it easier to fall asleep. Kinda like if you blink a bunch of times when in bed, it will help you fall asleep faster.
Covey Thanks, maybe I'll try that when I can't fall asleep
4:36 At last, the face reveal of the voice of TED-Ed.
Thank you ted for making these videos! Love from India
"Zeitgebers" 😂 I wonder why such simple words are sometimes just not translated, but the plural is built with the English grammar rules.
the irony is that Zeitgeber is singular and plural at the same time. the determiner determins (haha) if it is singular or plural
*****
Yes. I was more wondering why they didn't simply translate it :)
+DasPikachu me too xD
Don't forget about these weird abominations like the Eigenvalue.
Also the pronunciation is incorrect. Should be in Deutsch way!
I work nights. Maybe this is why I hate existence
if your a human not a working machine for the society
I hope you'll find a job at normal clock hours, good luck!
Phil Latio same
This is so beautiful and amusing!
"Only time will tell."
+1 for ending .
Thanks for good video.
Mind blowing
Just one word, *Awesome*
"Only time will tell." You just had to fucking say it, huh?!
perfect video ever thanks we need more like this
Much sought video for days I was thinking about this type of content I landed in today's search.
Thanks Ted
The first cave experiment demonstrating the circadian rhythm had actually been conducted by sleep researcher Nethaniel Kleitman back in 1938. He stayed in cave Mammoth, together with one colleague, for 32 days. Kleitman is largely considered the first sleep researcher.
I'm watching this at 3:17am, nice
I am addicted to your voice😁
Thanks for the information
Every time I heat some food in the microwave, I always get the signal that food is ready in about 10 sec before the food is actually ready to give me time to go to the microwave. This is so cool
thank you for this video!
my science teacher loves your videos.
wonderful!!!
Awesome Video!!!!
The passing of moments are natural! The concept and (abuse) of systemic time is a decree, human management and expectation. Love to ALL
THIS IS AWESOME DATA!!!!
He didnt talk about Pineal gland which secreats Malatonin and pineal gland is responsible to keep track for time, which is another dimension of space apart from 3D-Space. Abilities of Pineal gland is more then, understood or shown, weather to connect us to higher dimensions etc.
Great Video
5:40 is my wake up time. I could set my watch to it.
I really enjoyed it and i have a question: What about blind people? How does it work on them?
They can potentially develop a disorder called “non-24 hour sleep-wake disorder.” If they do, then they need to keep a fairly strict schedule about the things that they can control (e.g., eating time), use light therapy (as most blind people still have some light perception), and take melatonin and/or a prescription drug like tasimelteon
guys i really like this channel and i will be pleased if you put bibliographic references about your investigation (just like a scientific paper does) . it will help a lot of people to investigate and keep learning :)
This is such a good channel
I know right?
nice effort!!!
your the best
awrsome vedio
Omg I was just asking myself this today 😱
재밌네요! 항상 잘보고갑니다🙂👍👍💘
Im a huge fan of chronosaucalogy... how much sauce you need at any given interval! GO SAUCE!
my body never knows what time it is to go to bed
Once upon a time, when I didn't have a watch, I could still tell you what time it was, with an accuracy of a minute or so. Even waking up in the middle of the night, I knew what time it was. How I did that, I don't know. Presently, I have a watch and a phone, so I don't have to rely on my brain any more.
The last question bears answer in itself already.
lol, I am procrastinating at 11 at night... On TH-cam
Plot twist: it's 11 a.m.
Well have you stopped procrastinating yet?
I do that... but at 1 am
I always go to get tea at 10:30, or around that time every night. Around that time I always get a craving for a cup of tea. I do this so often my family thinks I have an alarm set.
Anticipate tube floor spending including raise second.
This makes sense, thanks for posting it! It also leaves me with a question: do the autonomous processes of the body differentiate between true sunlight and, say, a night light in your bedroom, when determining whether to shut off melatonin? In other words, should you never sleep with a night light on?
Yes, you shouldn’t sleep with a night light. If you want one, it should be red in color (as this has the least effect on the circadian rhythm).
on the weekens, i wake up at EXACTLY 10AM, no matter how soon or late i went to bed
Fox Mcfat same 😂
ikr
Sir ko Salute
I am watching this video 5:30 AM. I should be sleeping now but binge watching ted ed videos instead.
so is it possible for your brain to just not get some of these concepts? when ive been sick and not working or in school for long periods of time i would eat and sleep when i felt like it, and fell completely out of sync with day/night cycle. theres been lenty of times ive woken up in the dark and dont even know if its late or early.
Definitely possible. That is likely what even happened to the guy in the video. They glossed over the part where he "slept at regular intervals" to make it sound more impressive, but he almost certainly did not sleep based on a 24 hour day exactly and likely shifted away in one direction or another while still maintaining regular intervals based upon that.
Riddles please!!
Cierto.
My body is rather smart and uses the eyes to look for a clock. ^^
dschonsie you made my day 😂
So that is why even I sleep at 3am, I still wake at 7am due to the morning light.
one time i remember waking up after a nap and i didnt remember anything. it was 9 at night but i didnt know because i didnt have my phone, at that point i was really confused because it was dark outside and i just woke up so i thought i overslept till 4 or 5.
me too
"Could each of us be experiencing time differently?" Yes we definitely are. It's called relativity.
the effects of relativity can be ignored at human scale
I always wake up at roughly the same time (6:30 am) during te week and 10am during the weekend and I don't need a clock for that. I think this has to do with it
cool
What if someone does a similar test but in a dark liveable box that travels around the world in different time zones via flying. Food will be catered somehow, sleep and wake time is monitored and the test will last 10 days. The test subject also does not know where it is landing therefore it does not know what time zone it is...
It’s a 1am curiosity
What about when you have to work overnight? Can you do a video on shift/sleep disorders?
Ha ha ha, only time will tell, you got that right, that you do!
I guess Ted-Ed forgot to mention how Siffre kept track of when he slept and ate. I remember reading somewhere that he used a long telephone line to tell his assistant every time he woke up, ate and went to sleep.
Top10
Mysterious One Hopefully not..😂😂
would love to watch how messed up body clock system can affect us.
can this Knowledge ,help to Cure insomnia or disturb regular sleep cycle ?????
Why is this on the trending page with only 51k views!?
press like when you set your oven timer and leave the kitchen only to beep at correct moment when you come back
I always wake up at the exact time I plan to wake up. Random times. How does that work?
3:27 - Watching this at 12AM
Aaaaaaa yeah 👍
Time is a tool you put on the wall or wear it on your wrist.
The past is far behind us. The future doesn't exist.
what were his waking and sleeping hours though? how long did he sleep and how long did he stay up in between?
the ending tho😎😎😎😁
what happened to our clock in the winter? when we didnt have heaters and the sun didnt come out (as cavemen).does our body temperature still rise?
External cues will help maintain circadian rhythm and keep body's homeostasis. Plus cavemen found ways to keep themselves warm externally. :)

Sur Sr that makes sense thanks
