This is the BEST video I have seen in ages. When I graduated Nursing School in 1990- they didn’t teach about this information... and a lot of your information is likely fairly new. I need to watch this again tomorrow (when I am not sleepy) THANK YOU

[@Sleepopolis]

Wow, thank you!

[@Ruby-fc5ho]

Wow, this video answered one of my life long questions.

[@professorschwartz2901]

Mind blown! Had no idea that when you go to bed influences the type of sleep you get more of! This was awesome; thanks!!

[@glacier_10_years_ago]

Simple and straight to the point, my best source for understanding sleep!

[@MdSanaUllah78]

Nice lecture, but why stupid music noise?

[@anasrifqi817]

Assalamualaikum dr, I'm Anas Rifqi Bin Mohd Azmi, in this video I have learned about the stages of sleep, I'm very interested about aspect of rem sleep which is new and very unic for me, I'm never know that our eyes was moving while we close it before, thank you for the explanation too, it contain good animation which help me more understanfing in image way than reading only ❤

[@bekky834]

Underrated video! Love the info!

[@Outsider_aa]

very well explained, thanks for the video

[@Sleepopolis]

Glad it was helpful!

[@jonson4448]

Nice video - I am really grateful for the nicely animated schematics and the smooth transitions. A mathematical question though: if one circle is taking around 90 minutes, 4 circles would add up to 360 minutes or 6 hours. In the video 7-8 hours were propagated as normal, so wouldn't 5 circles be the standard? Or is it because or REM-phases tend to get longer, while NREM-phases stay the same length?

[@khushijain238]

[@user-jb6tv7sd8g]

It’s a great informative video but unfortunately the music is too loud

[@paultessar8475]

Gotta agree with the loud music. Very distracting and made it difficult to understand.

[@philipbaldwin2078]

Very nice video, thank you.

[@Sleepopolis]

Glad you liked it!

[@samymunoz-ceron6930]

i’m trying to figure out when my last cycle of sleep would end so when my alarm goes off I don’t interrupt it and instead of fighting myself to not go back to sleep - I just wake up refreshed. which I have experienced both I just don’t know what influences this; I typically go to bed around the same times and try to wake up at the same times. some days are harder than others though. If someone knows how to help with this lmk!! thank you 🙏🏻

[@Kartik-xw7yt]

Thanks a ton 🤝 This is helpful 😊

[@Vee_TheWorshipper]

Really interesting and easy to understand. Fantastic job. I have a question though. I read somewhere that there are 5 stages of sleep. 4 NREM stages and the rem stage. The source also stated that many people tend to group n3 and n4 into one - the slow-wave sleep (as you did here) What do you have to say about that?

[@papihuey]

I believe the 4 stages in NREM is the old data, now scientists have updated the source. 3 stages of NREM and 1 stage of REM = 4 stages per cycle

[@joehill2502]

If you wake up during n2 and then go back to sleep does it start again from n1 or just go back into n2 ?

[@pittviper6320]

Hi. I do suffer from sleep paralysis. It is horrendous! Do you have information on this?

[@yuvrajahire5901]

HELLO CAN I USE YOUR VIDEO FOR MY SCHOOL PROJECT

[@JmeWalton-re1ek]

Why do so many have such loud distracting crappy music during the actual speaking?

[@GL4C13R_Games]

Fr

[@allag3]

It adds nothing to the content of the video. Matter of fact, I’m outta here.

[@radar0412]

I lost my natural ability to get stage 1 sleep because of shift work. Stage 1 sleep for me is ALWAYS disrupted by sleep starts including exploding head syndrome. That didn't happen before the Shift work I did. I no longer do shift work but still can't achieve Stage 1 sleep. Any San Francisco based doctors you can reccomend or sleep medicine I can talk to my Doctor about?

[@barrymargolin6962]

Awesome video and explanation Zoey. I suffer from chronic insomnia, so its interesting to see what stages my body may pass unless I medicate with prescribed medication. Thanks again

[@aidiqhaizal5799]

Assalamualaikum I’m Mohamad Aidiq Haizal Bin Mohamad Hazki (1220115) From this video i understand that sleep has 4 stage that is n1,n2,n3, rem. Each level has its own function. If one of the stages is not reached then the sleep cannot be counted as quality sleep. It is also closely related to our brain system which is doing the recovery process during sleep.👌🏻✅

[@adamden5675]

The background music in your video is incredibly annoying & makes it difficult to understand your conversation!
