- Sleep is central to maintaining your physical and mental health, but many people don't sleep enough. We all do it, but what happens to us when we sleep?

Every night almost everyone on the planet enters into a state of unconsciousness and paralysis - but what is really happening inside the body when we drift off, and what's the impact if we don't get enough sleep?
Sleep is regulated by your circadian rhythm, or body clock located in the brain. The body clock responds to light hews ramping up production of the hormone melatonin at night, and switching it off when it senses light.
There are four stages of sleep that the body experiences in cycles throughout the night. On a good night we cycle through these stages four or five times.
Stages one and two are light sleep. This is a transition from being awake to falling asleep. Heart rate and breathing begin to slow, body temperature falls, and muscles may twitch. Stage 3 is sometimes referred to as Delta sleep - because of the slow Delta brainwaves that are released during this stage. This is the first stage of deep sleep where our cells produce the most growth hormone to service bones and muscles, allowing the body to repair itself. Stage 4 is where we begin to dream. The body creates chemicals that render it temporarily paralyzed so that we do not act out our dreams. In this stage, the brain is extremely active and our eyes, although closed, dark back and forth as if we were awake.
Humans roughly spend one third of their lives asleep. Modern lifestyles, stress and the proliferation of Technology, mean that people is sleeping far less today than they were a century ago.
Sleeping less than seven hours per day is associated with an increased risk of developing chronic conditions which could reduce life expectancy.
So for a healthier longer life get some shut-eye

I will always find it funny that before we fall asleep, we PRETEND to be asleep. We close our eyes, and wait… wait for our body to enter sleep mode 😂
😂😂
Bruu For Real😂
i just feel angry why i am not conscious even in that state............how much my conscious is just too weak
That's the problem with me, sometimes I just pretend and I can't initiate the real sleep...that's when I get angry...I find out that taking a shower before going to bed help me to relax and truly sleep...I also take magnesium in the evening to help me sleep better
True😂😂😂
As a person who have slept many times, I can confirm that this is what happens during sleep.
😂😂, We know right
🥱Lucky you
No ! No !! It's not true !
#1 résumé achievement

I think the reason why we like to go to sleep late is because our day is so busy that sleeping is like ending your free time. So we stay up as late as we can and end up not getting enough sleep.
yes, and it is a condition called bedtime revenge procrastination
Well said
Hit the nail on the head
That's me every day 😢
Yeeess!! It's called revenge sleep procrastination. It's bad!!
The music in this video is just fantastic.
Dive Down by Bob Bradley & Thomas Balmforth. Hard to find but a great song indeed.
its time by hans zimmer, i noticed it right away. was used in that movie Inception which was about sleeping so maybe thats why
"Sleep more for a longer life"
Schools: Let's pretend we never heard that..
Because schools are for indoctrination of humanity, not for humanity's benefit.
Ironically, especially American medical schools...
Literally
Yet research shows later morning starts for teenagers and later end of day aids concentration and focus and the reverse is for junior kids where early starts work better and early finishes. So lets start school at almost the same time as every adult needs to start work. I wonder if any country would consider changes to work days and school hours depending on Winter-Summer. Since living near the equator means similar daylight/night hours- does sleep research show it works better as citizens are seeing darkness and daylight at the same time

I need to show this to my mom. Thank you, you guys safe my life I can peacefully go to sleep now.
What is your mom letting you stay up this late
I've actually witnessed how dreams begin a few times. The best way I can describe it is that my brain falls in some sort of subconscious state where I'm imaging these *thoughts* or *images* (like random shapes or whatever) as if I was going through my memories and it all seems normal and natural whilst I'm falling asleep. However, I've had this process interrupted a few times where I've *snapped out of it* and instantaneously forgot what I was seeing and couldn't remember what it was in the same way as we can never remember the beginning of our dreams. I am convinced that this is how everyone's dreams formulate
@Abdisemed Mussa thank you
Ayy that I was the only one Nahhh
This is just... BIG FACTS
Genius bro.
during a period i could notice when my brain started to drift off like my imagination was unleashed but not anymore
Im 26 and have already developed heart disease because of working/gaming at night.
Don’t do it. You can’t reverse the damage.
😢🙏🙏😢 hope your ok stay strong
You might. With a vegan diet
I game a lot, work a lot, but i also sleep a lot.
Okay, don’t die
I wish you great luck
Thank you for letting us know
Sleep is just such a beautiful, peaceful phenomenon, i just love to sleep, there's a quote i say if I have a worse day.
Sleep for now and you'll recover till morning, if you didn't, you just didn't sleep enough
Watching this as i stayed up all night. Currently 11am. 🙃 I now understand the importance of sleep and I'll gladly fix my sleep schedule and get sleep every night.
How did you do it im currently struggling
Prioritizing sleep is the first imperative of living well.
SO TRUE! I am s passionate about this!
@@adhdfitgirl what if you struggle with insomnia? I've never been able to sleep from night until morning without broken sleep. My body just doesn't allow it.
@@mikehopkins3099 I struggled with Insomnia for SO long! Insomnia is usually caused by inactivity (if you are not physically active), bad diet or caffeine consumption. If those not the reasons there could be muscle tension. If you are tired enough and made sure you have released the tension in your body, you will fall asleep like a baby even if you have a busy mind.
@@adhdfitgirl Thanks for the reply I really appreciate that. With regards to diet is there certain foods you could recommend that helped you?
@@mikehopkins3099 you’re most welcome! I am glad it was helpful. I was very overweight. In my journey of weight loss, my sleep automatically improved! I talk about sleep on my channel too.
To pit it simply, i cut sugar completely, stopped ordering out and started cooking! If you do that already, pay more attention to micronutrients and omega 3s!
The Human body is amazing

"Why we sleep ?" is a GREAT book that delves deeply into this subject..
I like stage 4 sleep. I find when I dream deeply I am much better refreshed in the morning.
i dream so much it feels like my brain overloads.
I no longer reach the stage 4 or should I say hardly
Lol, it's reverse for all others, when we are in deep sleep, we feel more refreshed and comfortable the next day.
Eric Lamse T I think that you can’t just remember your dreams and it’s normal it’s cool if you can remember some like me remembering a dream is so beautiful but sometimes nightmares too
I’m at stage 4 right now
Falling asleep for me goes like this: I think about anything, and it slowly progresses into a stage where I get weird, abstract ideas. I begin to focus on my thoughts more than on the feeling of my body. Then, without any notice I fall asleep.
Same. Many times I start having wacky, abstract thoughts and then think so my self. "wow, that was a wierd thought, I must be about to fall asleep, yes! at last!" Then I never remember much more after that until I wake up in the morning :)
Yeah I think that's what happens to me too! and then sometimes during that in between stage, I'll "wake up" or just become fully aware of my surroundings again. And it's weird, because when that happens I immediately feel lighter, not physically, but it feels like some sort of invisible weight has been lifted off of me. It's a little difficult to explain but yeah
Thanks for reminding me what im missing out on all the time.
I am 68 y.o. I have never slept more than 4 or 5 hours a night my whole life. I am in great shape. One reason maybe because I learned, at a very early age, to control my dreams. As a small child I suffered from terribly, horribly bad dreams. My mother would yell at me for screaming in the night and tell me to stop screaming and waking her up. I started to play the dream over in my mind. Asking, how do I change it? What can I do to stop it from scaring me? How can I be my own hero? As I lay there thinking what to do, I would fall asleep again and then change the dream. It took several weeks or months before I could control my dreams without waking up, but I can still do it even today.
Is 5 hrs of sleep sufficient?
@@anishranabhatchhetri5282 It is for me. I have never suffered from lack of sleep. I sleep very deeply for the whole 5 hours.
I have done this for years-changed my dreams, like you described. But I sleep a lot.
@steven F
You are a lucid dreamer then
@@vermont741 I think of myself as a survivor.

Thank you for your great explanation❤
Idk why I find this video satisfying! ❤
I have always tripped out on the body when sleeping it helps us when asleep if you feel weird or uncomfortable you go to sleep and you feel better the next day like nothing was wrong…..your body recovers in a crazy way
That's why sleep is the best chill
You can wake up and feel weird so
No wonder I feel like death all the time. I work a warehouse job on a 2 shift rotation of 2 weeks of Mornings 6am-4pm, and then 2 weeks of Nights 8pm-6am. I've been there for 5 and a half years and it's fair to say I have literally felt my mental and physical health go down hill since
Get a new job
🤣🤣👍no how u feel!
That’s too much punishment to the body
How are you able to do this to yourself? Like I genuinely wonder because I can’t push myself too hard or I literally tell people I don’t care and to eff off I’m staying home… some people have some wild stamina
Night shift is death, stop working nightshifts. I guess we can say, we cant cause some occupations need steady readiness.
I’m watching it before I go to sleep, just to know what will happen to my brain in 15 min
Gotta say, the graphics in this are beautiful 💙
sleep is incredibly underrated. this is your body’s time to regroup and repair. that’s why it’s crucial to get enough sleep after physical activities.
Also the only time of the day when you don’t have to stress or worry about anything, you basically escape life
i wouldnt call it underrated.
@@DB-gl3jx i said that because a lot of people purposely stay up late and deprive their body of sleep.
@@itsurboidonnie yes and people are always like “sleep is for the weak” nah, sleep is for the strong, literally. People who lift have to sleep to gain muscle.
Great short video. It's very true that sleep is so important. I've focused on making my life stress free. I sleep better which is healthier for mind and body....and I exercise.
Yes sure thing.i liked this video as much as you do
This was so soothing to watch and listen to. 🥰 The body is such a magical thing. Great video!
If i pay hospital and get sleeping until i die what happened?
Needed this terribly
Thank you for bringing "sleeping less is bad" under the limelight cause i think that people that do sleep have to face a competitive atmosphere against those who don't sleep and spend their time working all night
only if you have the option to be born as what, a human or even near one would honestly be my last choice
No human can go without sleep or a very small amount. Those who work all night as you say either die early, suffer long term health issues or end up unable to concentrate during the day. It looks like competition but its not really, its presenteeism. Even those who do night shifts are shown to suffer long term health and brain "damage", even if they are in theory getting 8hrs sleep in the day.
@@stephendoherty8291 What damage am I getting? I sleep at 5am and woke at 10am. I and haven't seen any damage. I exercise almost daily. I don't drink nor smoke.
Amazing how our body works even when we are unconscious.. take care of yourself fam🙏
Amen 🙌 💖 💯
Yeah
Like the way she talk 🦜 so sweet
I can strongly believe that those stages repeat only once or twice in my body.
Obviously in this video too, the experts say that in order to live better we need to reduce our stress. But listening to that I feel myself more stressed than before.
I have felt sensation of going into sleep, i just have my thoughts going through and like a seamless and perfect transition go into a dream kind of related to the stuff i was thinking of. I only realise this happens when i wake up again but holy mother it is amazing!
not sleeping for a second for more than 2 or 3 days have strange effects on your mind and body, unexplainable things you can feel, is like your in the 4th dimension spiritually....... but it is difficult to sleep normally when you are already very old maybe this is the reason all people are going to die...... i wonder what is like if people doesn't sleep and yet they are all healthy and their body and brain will heal automatically. the brain has the power and function to recall or remember so we have to sleep to put our brain and body do the job. thank you to "the economist" for sharing this informative video.
This is so satisfying 💆
*When we all fall asleep, where do we go?*
Quite a good timing I'd say.
Lol
you are in your bed
Sleep it death Gods takes our souls when we are sleeping and than He returns them Our Lord gives us life everyday.
@@islampeace... Stop smoking rocks.
@@philbecker4676 it’s true. Your soul isn’t in your body when you sleep
It is truly amazing. We don’t even have to do anything we just close our eyes and our bodies knows what to do. Truly an unbelievable creation
Think of when you cut yourself even just a bit. You don't need to ask, your body is already healing itself 💕
Your heart beats all day everyday without you asking it to. Our blood, bones, muscles, cells, and so much more working hard for us all day everyday 🙌💕💯
Exactly ,This world is amazing….
Wow such a great video!
Thanks for sharing this knowledge ⭐
Many biological processes happen during sleep: The brain stores new information and gets rid of toxic waste. Nerve cells communicate and reorganize, which supports healthy brain function. The body repairs cells, restores energy, and releases molecules like hormones and proteins.
Why does this not also get done during the day even if energy requirements would be higher. Is it an acceptance that the brain cannot multitask? Why only in delta sleep? Does it work standing up (like astronauts)?
Brilliantly done video. Will be sharing this with my class.
Lol glad in my day teachers got their information from books and research. Now it’s social media and TH-cam. Very worrying
Fantastic! Sleep is our health overall, whenever it's mantain.
Great Video! Love it!
This is amazing! No, really, this is absolutely amazing! Is so magical to see how incredibly and complex our bodies are.
If it were only true
Thanks for this video.. as a Doctor I seriously support your point of view. 🙂
When you're trying to sleep and some weird thoughts start to come out and you have not remembered when it started or like where it started from then know you're falling asleep.
Very informative. Thank you!
Just watching this made me sleepy. The background music is very relaxing
Watching this video makes me want to sleep
Thank you; I used to sleep 8-9 hours back then, then turns out I only slept 30mins yesterday due to exam stress and feeling like I haven't learnt enough. My friends and family have been saying to get some sleep for years, I hope I do asap.
To the point and perfectly explained...👍👍
As a sleep expert where I do this every night. I can confirm that this is true.
Watching this at 4am😂☕️
It's interesting how during in my waking life I have this small, unimportant thought then when I go to sleep, it is literally what my dream is all about.
Thank you for sharing.
Wow. Will be amazing having control on our 4 stage in terms about our dreaming mode.

I never knew The Economist did this sort video. Thought it was solely for political and economic videos
That said, really interesting video. Love the factual side of TH-cam!
We spend 25-30 years sleeping but I think people fail to forget that that’s added years to your life because of sleep. With that 25-30 years comes and extra 60 of awakeness
Bro this is amazing
Very informative video...keep making such videos
If I may ask just several questions in case you guys thinking to make more videos:
1. What about oversleeping? What happens then and is it bad?
2. What about sleeping during a day?
3. What if a person sleeps only at daytime, and works at nights?
4. What if u wake up in the morning, and fall asleep again accidentally (well I usually see bad dreams if it happens).
5. When our bodies fall asleep where do we go? Billie wonders that too
1. Very bad you get fired for being late
2. Again you get fired
3. You have it backwards work during the day sleep at night
4. See 3. above
5. All depends

There was actually a time where when I was in the middle of sleeping I had a dream but not just any ordinary dream it's called lucid dreams it's where I think you move around your dreams I witnessed it and it felt amazing lol it felt like I was in another dimension and world but I kept on waking up cuz I felt like it was in the real world (my dream) so I kept waking up and sleeping and everytime I go back to sleep my dream resumes and I move around freely again. It was the best experience I ever had ever it happened when I was 5 or 6 or 7
Awesome! so were there any people in your lucid dream? or was it just your room?
@@tukislovestakis there was my cousin my friend and my family actually
@@tukislovestakis you can do whatever you want in a lucid dream. It is just like real life while you are sleeping
@@sktsxterritory7339 its wear your conscious mind relies its in a dream without waking up their fore its like you can direct your own moive in your head if you will ive done it tons of times i was spider man once and another time i was iron man but when i first lucid dreamt I was dreaming something i dont remeber but i was like wait no that never happened before i was like oh wait this is a dream i told myself without meaning to and i literally woke up without physically waking up its truly a rare thing but when you do it enough times you can trigger more ofter like i do
I had something similar when I was younger, I had a dream I wanted to continue so I decided to just fall back asleep. Turns out I accidentally chained 5 dreams in a row, all continuing where the previous one left off, turning it into a whole series. My father was concerned because I apparently had been asleep for 15 hours! Whoops!
Great information
This was a very pleasant presentation ❤
I finished this video and then told myself to go to sleep
I never thought,not having enough would put your body in risk like that.

I’ve always suffered from horrible night terrors so I rarely get sleep at night but once the sun comes up I can finally go to sleep with ease🤷♀️
eat the sun and gain it's power
try to listin to quran recitation before you go to sleeep it realy helps
i believe when we dream that our minds drift off into memories, situations that our mind wants us to see or reanalyse
also for example, when you have a dream which effects you emotionally it seems to me the mind is saying basically look at how you react to things that dont matter or arent even real which then gives you insight in waking life
