This is the best sleep stage/sleep cycle explanation on RU-vid.

This might just be the best usage of a whiteboard for a presentation, that I have ever seen

Watching this after reading Why we sleep by Matthew Walker. Amazing book. Amazing video. Simple and comprehensive

I’m studying for the EPPP. Excellent lecture, thanks

Hi, im from Malaysia. Not from science student but taking psych major as my degree. Just want to let you know your explanation is really good and i understand all of it. It help me and my friends a lot. Thank you so much !

Great lecture! You keep the audience intrigued.

I think it is more short and expressive that makes it awesome video on the topic

Great video, crystal clear, thank you!

Excellent!! Best video ever about this topic❤

you explain so well it suddenly became easy to understand

The Best Sleep explanation I have ever heard

Thank you for this video. I have been more aware of having hypnic jerks, and thought there was something wrong with me. It feels like being startled and I thought maybe too much cortisol. I've researched hypnic jerks and now I know that they are part of normal sleep cycle for up to 70% of people. I wake up every day feeling rested.

excellent as I'm just starting and you broke it down so well. I appreciate that

This is by far the best explanation of sleep I've seen on YT, immediately subscribed and thanks for your hard work

Amazing video, i dislike listening to most lectures at school but your lectures make me love learning and studying. It really depends on the teacher and you're an amazing one

Excellent presentation, thank you so much! Your enthusiastic, confident teaching voice, speed & timing and simple, accurate whiteboard content was a pleasure to follow. Your 20 minute explanation helped me to consolidate and visualize many of the points made by Dr Andrew Huberman and Matt Walker (in hours of podcast material). Well done. 🎉

You are amazing!! The best to demonstrate this!

Great Lecture sir 💗 Thankyou so much for this .This class just made very clear about all the doubts that i had about sleep cycle& stages

Thank you so much for your detailed video. I have been searching for this!

Thanks so so much for this video it clarified a lot of questions about the spinal cord and sleep I had.

I have a presentation tommorow relating to sleep cycle and this video helped me so much. Thank you!!!

SUPER......very well explained for a layman like me....the right level of technicalities....i am a 56 year old veteran!

Thank you for making this SUPER Awesome video! I really like the analogies you used; they are extremely helpful to me to make sense with the information. Thank you again! 🤝

Very engaging video! Just like a college lecture. If I wasn't watching from my phone, but on a big screen (e.g. TV), I'd be looking for a spiral notebook to take notes as if back 30+ years in college. Watched until 9 minutes, will complete latter.😊👍

You are an excellent teacher Sir

First, thank you for giving such a simple understand of circadian rhythms I have ever heard. Second, in my study of circadian rhythm, I'm trying to understand the difference between Suprachiasmatic Nucleus and Chryptochrome? Are you versed in this? In your humble opinion. Thank you

Thank you. i have to follow you

Thanks you very MUCH SIR

Very cool, do you have any information about circadian lighting and how it can effect sleep?

Excellent...🎉🎉🎉....

Great explanation that was clear as a whistle! I salute your efforts on making science as it should be fun, easy and approachable . Just a question... in which stage do we toss in bed? It's clearly not in REM but in which.

Thankyou sir for such a great lecture 🙏🙏...can you please explain condition of sleep paralysis??

It was great

I have virtually no REM sleep. I use an Apple Watch and use the Health App to monitor my fitness and sleep. In the past few weeks, it has shown little to no REM sleep. I can't remember the last time I actually had a good night's sleep. I have Parkinson's Disease and have had no indication that I might have REM sleep disorder. However, I do use medical cannabis to help me sleep and it doesn't work very well. I wake up every day exhausted. I know that I probably need to get a sleep study done to see what's going on but I can't imagine falling asleep in a clinic with so many wires attached to me.

Thanks

thanks.

I get a lot of theta waves when I'm awake, most of the waves amplitude ( up or down ) is theta . The rest of the waves are pretty much the same on RAW EEG. MRI and medical EEG checked fine, but what is theta wave suppose to mean when I'm awake and goes through the whole day like this. * Readings with a 16 electrode, on the prefrontal cortex

Hope all you shiny happy people get a good night’s sleep.

I have sleep apnea. My reports show 4 stages before reaching REM sleep. Can you explain this 4th stage? Further, my report showed that I bypassed stage 3 and 4 and went from stage 2 to rem sleep all the time. Further, the time spent in stage 1 was minimal. I was in stage 2 or REM sleep most of the time (over 95%). Is this normal? Finally, can you give an approximate idea as to to how much time (as a percentage of total sleep) that one should spend in each stage and in REM sleep?

Well this explains late morning sleep induced exhaustion.

Dr. Kushner, I can very much tell how intelligent and beautiful of a teacher u r. I've had trouble sleeping for most of my life and this video brings a great deal of awareness & education to me. I truly appreciate every second of this video! Thank u sir 🙏 ❤️‍🩹❤️‍🩹❤️‍🩹

You explained it so clear! Thank u so much! I now understand this better! Subscribed!

Does the process continue from where it had stopped when you wake up in the middle of the night and then go back to sleep a few minutes later?
