What Are Sleep Cycles? - Everything You Need To Know!

- While you are sleeping, you go through a number of 90-minute sleep cycles. During in each cycle, you go through four sleep stages.
During stage one, also known as light sleep, you are sleeping, well, lightly. This stage lasts for between one and seven minutes. When you are in light sleep, your breathing and heartbeat start to slow down, but it is very easy to wake up if you hear a sound.
Now, during stage two, you are sleeping a little more deeply. In this stage, called intermediate sleep, your breathing and heartbeat continue to slow. It is a little harder to wake up during this stage, but you will wake feeling refreshed.
When you reach stage three, deep sleep or slow-wave sleep, you are sleeping much more deeply. Your breathing and heartbeat are very slow, but your muscles and bones grow and heal. This is a rejuvenating stage of sleep.
Finally, you get to stage four, REM sleep. During REM sleep, your heart rate and breathing increase and become irregular. Your eyes start to move quickly behind your eyelids, and your most vivid dreaming occurs.
It is good to consider this information if you like to take a nap. You don’t want to wake up during a later stage (like three or four) because you will feel very groggy. It is better to nap for around 20 minutes so that you are only in stage two or nap for a full 90 minutes so that you have gone through the full cycle.

we human don't just sleep the same time and wake up the same day due.. to what we do are not the same.. i do had some issue that i can not sleep like one of two time a week.. however... i can adjust my sleep due to being a business owner.. and i had been dealing with it since my school day... best thing to deal with it is you just had to accept that tonight you might not get any sleep and yes you will feel like shit.. but it will be over..
The older I get, the more I love sleep.
teenager also.. they just want more time at night but in the end their body will gave out...
Aint that the truth
soo agree
I'm your 100th like
Deep
National Sleep Foundation: Teen agers must get 8 to 10 hours of sleep
School Systems: We don't do that here.
What do you mean ? Students get around 8 hours pretty easily. Sleep at 10 and wake at 6 done.
Anurag Sosa teenage years are probably the best years of your life socially. So to decide between sleeping at 10 (which is considered early for most teens) or to stay up later or go out later is a tough thing to do. If schools started later and finished later then it would greatly increase productivity. Especially since many studies show that a teenagers brain doesn’t reach full wakefulness until atleast 11am
@@te3hee3 I don't know if that's the case. I get 8 hours of sleep easily. Also I'm not socially active.
Vedang Shendye What do u mean, middle schools are only 7 hours pre day(9to4) you have 7 hours in school and 17 hours of free time, you could totally spend that 17 hours sleeping insted of scrolling through TikTok or playing video games
@@aptechtvbts642 Agree
This is so underrated this has so much information in it. I wish more people would watch this
@Guts lol heyy
@Guts aw thanks same to you :)
Got to the bit about not having screen time before bed ... whilst lying watching this in bed 😬 very helpful video!
This was a very informative video on sleep cycles, this is the first time learning about this information
Understanding sleep cycle_
1. 1:30 hour(90min) one sleep cycle_4stages
🌟Stage1_Light Sleep 5-7 minutes
🌟Stage2_Intermediate sleep 25min, u don't feel groggy if u wake up this tym
🌟Stage3_ deep sleep, can't wake up easily
🌟Stage4_REM sleep rapid eye movement, dreams come, memory storage
Nap time_10-30 min
Or completing sleep cycle
This video is FULL of good..accurate...insightful information. Lot of things i knew but also learned a couple things. Thanks
Nice video, I found value and good information. I've been paying more attention to my sleep this year and have seen a lot of benefits when I'm consistent with my sleep.
Thanks for this info. I discovered that I needed 8.5-9hrs of sleep; now I'll monitor what part of that 90min cycle my body wakes itself up at.
WOW! I didn't know about there are 4 sleep stages. I normally woke up on stage 2 and/or stage 4. I am having very difficulties sleeping early every night. I will try your tips. Thanks for the useful information.
Very informative video! I think I need to do shorter naps and wake up in stage 2. I usually feel worse if I nap too long and wake up startled and heart beating fast. Idk could be something to do with the anxiety or the stage of waking up. I like to have it cold and pitch dark when I sleep too and no sounds. Thank you for all the info!
Really helpful👍🏾
Loved this, extremely helpful, simple but it has everything important
Glad it was helpful!
Thank you man! This is awesome.
Glad you like it!
Super. Nice explanation tq
Much underrated, Great content
Glad you think so!
This was a great video! Thank you for the info
Glad it was helpful!
thank you so much for the precious information thanks a lot❤❤❤
You're welcome!
The best video on stages of sleep
Thanks man for making this so easy and interesting 💕💕
You're welcome. Thanks for watching!
Hello! So glad I came across your video! I'm concerned about myself as I only get deep sleep at the beginning of the night in a few cycles which is roughly around 45 mins a night? I'm 24 years old, keep fit and healthy and try to get to bed at good timing but why am I only getting deep sleep at the 1/4 of my sleep? Never any after that!
Very useful thank you so much! ♡☆☆☆
thank you it was so helpful 4 me
Glad it helped!
this information was quite helpful
thanks buddy
No problem 👍
Very interesting info was not aware there were four stages of our sleep
Most excellent information, thank you very much.
Glad it was helpful!
Nicely explained..!
Thanks...
Glad you liked it
One of my cats wakes me up at the end of every sleep cycle - they must cycle for 90 minutes also. Excellent info - thanks for doing videos like this.
You are welcome!
I nap alot as I'm in a ton of pain. I tend to sleep from 20 mins to 2 hrs which isn't fun but I get what I can. I didnt know everything about sleep cycles so this was very helpful. I leave my TV on 24/7 too otherwise I get nightmares.
Take Nutritional Yeast for nightmares. Take a good tablespoon before bed. Vit B1 deficiency gives you anxiety and nightmares
I knew about rem sleep but I had no idea there were 3 more stages. I love informative videos like this! Thanks...The tips to help get to sleep are spot on, everytime I open a book I fall asleep after the first 4 or 5 pages. It's as good as a sleeping pill..lol... and it caused some bad grades when I was in school...I was only able to read The Odyssey 4 or 5 pages at a time so I missed deadline for my essay😮..haha
The Odyssey is great! I used to read Tolstoy before bed. That always put me to sleep.
Very informative. I learned something new today. I never reach stage 4, maybe not even stage 3 since i suffer from insomnia. The littlest things wake me up and its so hard to fall back asleep. I get about 3-4 hours of sleep a night. But recently i started taking CBD oil and got a white noise machine and its getting better, thanks to you guys at Mattresses Clarity for all your informative videos of all these products. Thank you👍
Very happy to help!
I use to sleep so very deeply and loved it, but not anymore due to health reasons. Now if only businesses and schools would adapt schedules more conducive to allowing all to get proper sleep LOL Great information, thank you.
I totally agree. More schools and businesses need to realize the importance of sleep.
the whole point of that kind of scheduels so kid adjust to that kind of business time... if they had to work anti social hour.. then it is best you had to learn ability to adjust to certain time not.. try to work whenever since your body can not deal wit it...
Interesting
Great video. I usually sleep pretty well, but I do like to use a white noise machine from time to time to help.
Yeah, I use one too!
Nice informative video. Is it “normal” to wake up after each completed cycle? Or easier to be woken up? I seem to wake every 2-3 hours at the same time most nights. Usually I take a quick bathroom break then fall back asleep usually without issue. Is this something I need to address or normal?
The reason i searched for this video s because slept at 2:30 AM and woke up by myself at 7:30 AM for work feeling sooo great and i was confused on why i felt good and less groggy even though i only slept for 5 hours. Good to know about these cycles.
You should sleep early
I would like to step to stag 4, dream away :) very helpful information. I need to nap more. Thank you for sharing:)
You are welcome!
Watching this video just before I go to sleep
National Sleep Foundation... I would like to assist to one of their meetings
2:13 about to sneeze
I wake up frequently during the night. Mostly because it's a comfort issue..I'm always tossing an turning.Also , I have to sleep with the TV on. I can't sleep with silence..if the power goes out or my TV goes off in the middle of the night, I wake up. And somehow I sleep better if I have a full stomach..almost opposite of the whole video..lol!! BUT, it's a matter of changing habits.
@kim charlton I've never understood how people can sleep with sounds and lights flashing, literally blows my mind
Thank you for another informative video. I need to get back to reading an actual book, not my Kindle.
Indeed!
I sleep on a $10 air mattress on a daybed no money honestly peace into the universe🌏🌌
This is truly remarkable. I encountered something with a similar message, and it was awe-inspiring. "Better Sleep Better Life" by William Brook
Reading an *ACTUAL* book 🤣 #relatable
I wonder if I have hot flashes during REM sleep....this was very interesting now I know why I wake up from an afternoon nap so crabby!
it normal that your heat will change.. since you are in lying down position...
According to my smart watch I get 30mins deep sleep, 6 hours light and 30mins rem. I always wake up feeling tired. 😭
How does this correlate to waking up during REM cycles and getting sleep paralysis or simply not being fully asleep but still having your body undergo the physical conditions of REM sleep? Anytime I try too hard to focus on getting a good amount of sleep I wake up with paralysis or simply don't sleep but still experience paralysis (though my body does feel rested afterwards). Not too concerned since I've become adept at exiting it and remaining calm but it is annoying and I would prefer to routinely wake up at stage 2
I’ve had really bad insomnia for a while about 2-3 years getting around like 3-4hrs of sleep a day my mind hurts so much
So is you cool in the sleep cycle of stages 3 and 4 is it priding to to listen to music before you go to sleep or read that wasn’t necessarily clarified-like Claritin clear
71 degrees?! Wow! That would get expensive here in Florida, but I see you have two beds in your room, so perhaps you split the bill…? Just wondering
How much of REM and deep sleep we should get , please i like to know
So if I’m understanding correctly we want to sleep at least eight hours depending on our age and within that eight hours we want to make sure that we reach all four stages in each 90 minute sleep cycle for the duration of eight hours. How do we make that happen though? How do we make our bodies hit all four stages? Is the first step to figuring out what time our body needs to start to go to bed? And I’m assuming this is different for each person? So is that called circadian rhythm and how do we figure that out?
I am going to be trying the Uberman soon, a polyphasial sleep schedule, where you sleep for 20 minutes every 4 hours (so 6 times every 24h), and that all day. So you never sleep for longer than 20mins at once.
@ 4:45. Blimey that's hot. (IF winter) not even day. I an do 68⁰f day but I lower to 61⁰f sleep but in wool blanket.
Summer is different. I'm aiming for 68⁰f
But the upstairs & downstairs units temps don't match real room reading. Sometimes it feels like 62⁰f
I actually wake up early during weekends 😅
Wait but I’ve been watching vids about how to wake up just before REM starts (for lucid dreams) and most of them say to set my alarm for 4-6 hours after I fall asleep so will I go through like 3 cycles during this time
why do I always feel like I make up my dreams and dream through out my sleep, and wake up remembering most details in my dreams while I was asleep, I actually feel like I remain in one stage through out the night, plus I keep on waking up in intervals every night, can someone please explain to me and recommend a possible solution
To let know the brain when the circadian cicle begins, a sun bath during sunrise helps??
is there anyway for us to shorten the sleep cycle?
a little bit of my personal experience, there are times when i wake up in the morning and feels like i don't get enough sleep and i'll just hit the snooze button (it's bad i know) and what happen is really weird.. i'm sure i feel like i'm falling back asleep, like into a deep sleep and when i wake up i thought "oh no, i must've miss my alarm since i didn't heard it anymore after i hit the snooze button" but when i look at my phone it's only been 1 minute since i hit the snooze button (my snooze last for about 5 minutes). the weird thing is i feel refreshed as if i have slept for 7 hours during that 1 minute. i can't control this and it just happen randomly.. i experience this a few time already. anyone else who has the same experience as me?
and if anyone else know about the theory behind this or better, how to trigger this condition, mind sharing it with me?
In my rem sleep I'm finding myself talking and acting out in my dreams
I knew there are 4 stages of sleep. I did not know they are 90 minutes each. I learned that athletes need stage 3 for recovery. I often wake during stage 3...frustrates me. I need more of the deep, restful sleep. Working on it.
Hey Joni! It's actually one 90 minute sleep cycle. During those 90 minutes, most people go through four stages.
NIce might want to paint my room black . . .
What is the high point in the sleeping cycle??
I get it thanks for the explanation but... my problem is I can't get to sleep... so I should be up at 7 am for work etc. This means I need to sleep at 11:30 right? So I will have 5 cycles problem is I can't sleep at 11:30 there is just noway.
where does the circadian rhythm come in to play?
71 degrees is very cold? 70 degrees is too hot for me. We are all so different in what temperatures our bodies prefer. 66 degrees in the winter and 68 in the summer are perfect for me.
Impossible to set an alarm for 10 to 15 minutes for a nap when it takes you an hour to fall asleep
Can someone go straight from light sleep to REM sleep or Does REM sleep always happens after deep sleep ??
So if you wake up several times to go to the toilet, then go back to sleep. Do you carry on from the sleep cycle you were in prior to waking up?
Thanks for the great video!!
You will start from the first part of the cycle.
Mattress Clarity oh know. I wake up 3-5 times a night to go to the toilet so probably never been into deep rem sleep!?
your system shut down at night... so it best to go to toliet before go to bed so you don't need to go... until early morning and then it won't matter what time...
Hey I get sleep paralysis so I got a Samsung band its says I only get 2min average every 7 days I wake up all the time every hr but I didn't know that until I got the band when I have sleep paralysis my band shows big stress and heart beat goes from 40 to 60 back to 40 wierd right
I don’t wake up.. ever. That’s why I’m always so out of it when I finally do lol
What about the alpha beta and other waves on these stages...??
ძმაო, შენი ჩრდილი ყველაზე ბნელ ჩრდილს ჰგავს, რაც კი მინახავს
why is readinga book ok and reading a screen isnot ok? Isn't it about your brain working in comprehending the text? Is it really about actual ligt from the screen (as in if you read the same text from the paper it is ok, but the exact same text from the phone - not ok)?
What happens when you wake up during REM? What happens if you wake up right after REM ends? When would be the best time to wake up to remember my dreams?
Sort of wondering how to wake up just before my REM starts or during it. I’m trying to learn how to lucid dream
you might be sleepy and go back to sleep... it all depend on your head..
So seems to be more important we sleep for multiples of full sleep cycles. 4 cycles would be 6 hours, 5 cycles would be 7.5 hours, 6 cycles would be 9 hours. Question is how many cycles do we subjectively need. Should we omit the alarm and wake naturally to avoid waking during stage 3 or 4
it depend. some people had very short cycles.. don't think of what but look at why you need more or less sleep... usally if you used up your body.. more sleep and don't do jackshit.. lesss.... but still best to had the same time of sleep and same wake up time...
Do you have a video on what happens to your sleep cycles when you go to bed super super super drunk? Or is it the same.
😭😭
Idk why I always wake at 5or7 even if I sleep at 12 and I only get some hours of light sleep.
What if I wake up automatically earlier than the time circle? Should I just wake up or continue to sleep?
depend.. do you need more sleep or you don't mind wake up.. this is when it go to had a clock you can see....
At 70 years old I maintain a 3-hour sleep
What stage does Freddy Krueger come in to play?
so it doesn't depend on how many hours you should sleep but how to complete yr sleep cycle so if i sleep maybe 3 hours so it's okay? i know i should sleep more but i just give u an example
Sleep duration is important too. Understanding your sleep cycle is helpful in knowing when to set your alarm. 3 hours is indeed too short. Experts say you should be getting between 7 and 9 hours each night.
Mattress Clarity ok but wich option will leave me more awake
1.6 hours of sleep, wake up at the end of a sleep cycle
2.8 hours wake up in the middle of the cycle.
don't matter as long as you get enough hour.. i can going for the one whole day... yes there would be a time you feel tired but that is normal...
I feel like I'm entering stage 3 as soon as my head reaches the pillow and nothing can wake me up until the morning lol. I even wake up in the same position 😂
Big Chungus xd
Lucky
6-7 hours ok for me age 29
Great video and informative, but SLOW down!! You were talking at 100mph bro! 😅
You have two beds????
5:45 I sleep in 64 degrees
I don’t think I ever have rem sleep
I feel bad for the ex. Damn i woken ur up many times during stage 3 :( just for 5 min "talk".
My light sleep is a few seconds
It's 4 am here.
What about you guys?
my nap lasts for 3 hours lol
These days, it's happened to me a few times!
if you used up your brain and body... it can happen.. i had like extra nap of 4 hrs since i was working so hard...in that week or week before...
You sleep only 90 min per day???
woah 4 sleep stages in a sleep cycle, super informative about each stage. Thanks marten!
First 3 fall under non-rapid eye movement to REM sleep. 😴
stage ONE : light sleep 1-7 minutes, wakefulness to sleep. Brain and heart activity starts slowing down.
Stage TWO : intermediate sleep about 25 minutes, muscle, and everything else slows down as temperature lowers.
Stage THREE: deep sleep. Muscles growing and immune system is strengthening.
Important for athletes or people that workout lol it’s okay marten, i don’t workout either but i love my sleep ☝🏽💓
Breathing slow, heart rate is slow, hard to wake up during stage 3. If you wake up you’ll wake up groggy. 😖😖😖
Stage FOUR: rapid eye movement. body going into beast mode, blood pressure goes up, heart beat increases and beat being becomes more irregular and legs and arms are paralyzed. Learning is happening, memories are being stored 😍
I love to nap but i always wake up at the WORST times. 10-30 mins napping feel rested but after that, you’ll wake up groggy but a full 90 minute, you’ll go back to feeling refreshed.
proper sleep we should be getting: teens 14-17: 8-10 hours
18-64: 7-9 hours
65+: 7-8 hours
Yikes i definitely am not getting the sleep i need 😭
Make sure bedroom is cool, dark and quiet for help in getting some good sleep.
Zomgggg i need some blackout curtains 😍 sleep mask and ear plugs and same sleep schedule even on weekends will be helpful to keep a good rhythm.
Having caffeine in the evening could disrupt your sleep ☕️ and think about what you’re eating 🍽
Don’t eat chicken wings an hour before sleep 😂 got it.
No laptops or electronics before bed. So so so smart, I’m on my phone for “5 minutes” and before i know it, I’ve been online for hourssss. My goodness.
I’m going to start doing my homework right before bed because that ALWAYS puts me straight to sleep 😂😂😂
Thanks marten! Mattress clarity is genius as always!
(I’m going to ignore that alcohol comment though 😂)
This is such dope information, i had no idea. I sweaaaar mattress clarity has taught me more than all 4 of my classes this semester 😂 love coming home to new mattress clarity videos lol
Awesome! We're so glad to be of help.
Kids?
What happens if you sleep 7-9 hours but from 12:00 am to 11:00 am
@Pasci K I would say that is still good just as long as it's your everyday routine
i try to sleep at 10 pm... if you try to adjust every 12 hr like i used since i used to living in NZ... it fuck me to so hard since i brian keep confusing what time to sleep... 10 years later still a issue...
lol make sure you go to bed at same time every night. that's hilarious. forced overtime shift work prevents any kind of normal schedule and not just for sleep.
He has 2 beds
if your neighbor is using a drill at 6:00 AM just google Mattress Clarity + how to murder your neighbor and get away with it xD Disclaimer: This is a joke.
6 am do aceptable for do light work but he do too often just tell him that loud work at start at 8.00am ...
I don't want to be rude but this dude puts emphasis on everything and articulates too much. His facial expressions are like DUDE YOU GOTTAAA CHEKX THIS OUTTTTT. He's talking so intensely like he's explaining hardcore rocket science.
