The Best Sleeping Position for Glymphatic Flow in the Brain

1. A German therapist suggested sleeping on the back is better to relax the groin, spine and shoulders, but I`ve always found it difficult. He suggests sleeping without a pillow with the chin down and a rolled towel under the knees in the first nights. https://www.youtube.com/watch?v=jRhDC1NfaI8

2. I love this channel!

3. nice

4. Ok so one vid says get at least 7 hrs of sleep, this says maybe stay under 8 hrs. Is there a general problem with sleeping longer than 8 hrs?

5. Now I have build up in my brain to worry about? Jeeze Dr G…I can't keep up.

6. "On your flank to not draw a blank." Love it. 😄

7. Fun fact: the Buddha recommended sleeping on the right side 2,500 years ago 🙂

8. Excuse me, on YouTube there are some channels whose videos have their audio tradition in other languages, it would be great if this could be implemented on this channel, I'm just informing in case you would like to inform more people 😃

9. sleep on your back please, you don't want to develop facial asymmetry over time.

10. As someone who has struggled to sleep in the past I’m glad i picked up endurance sports as a hobby.

11. 👍

12. ….righty tighty! (yes!)

13. Since going WFPB I seem to need much less sleep, sometimes getting only around 4 hours. I wonder if this could be an artifact of my very low inflammation, or if I should seek help to get more sleep. Just musing. 🤔

14. In short, the research cannot be trusted.

15. Sleeping on your back increases the likelihood of OSA (obstruction) and could easily be a confounder.

16. 04:16 "Longer sleep duration is associated with signs of systemic inflammation"
    Now does it mean that we try to cure ourself of inflammation through sleep?
    Or is longer sleep causing the inflammation?

17. Super interessant

18. Cornershop says sleep on the left side, keep the sword hand free 😊

19. I sleep like a bat and keep waking up with tremendous headaches. So this video was super useful for me.

20. can you wash your fruits/veggies with a bit of handsoap and lots of water… or does the soap go through the skin into the fruit/veggies.. friend does it with just water but with pesticides/covid/ e-coli/ etc it feels not save just to use water…

21. It would be interesting to know how soft the mattress is. In nature there may be grass, which is much harder than any mattress. The bones lie on the ground. In a mattress, they sink down.

22. Please help me to find this out: Did the meta analyse cited at 3:21 adjust for physical and mental health? that would be a nice info to have! 🙂
    And basically the same question for the study cited at 4:17
    To have those infos would be helpful to sort what evidence we have about the impact of longer sleep, if it is causation or reversed causation.
    Thanks! 🙂

23. Super interesting! Many people tend to snore while sleeping on their backs, perhaps there is a link between oxygenation and sleep quality as well?
    Love this research coming out – hopefully we will find more of the missing pieces to find real solutions

24. I know that you want views, but if you would summarize your findings in like two or three sentences (which you could do) in the video description, that would probably help those of us who don't want to listen to five minutes of dry research article summaries. I only want to know the takeaway, after all. I appreciate your work but we all live such busy lives!

25. The hilarity of people being able to sleep in one position at night blows my mind. I catch myself doing acrobatics some nights

26. In Yoga for adults , they recommend sleeping on the left side. But if you wake up in the middle of night, then recommend sleeping on the right side. Never flat on the back or on stomach.

27. Thought it was better for you sleeping on your back? Sleep research leaders say back sleeping is the best choice? What to do?

28. How about drinking in two sets of 4 hours like we ve been doing before artificial light?

29. My chiropractor told me to never ever ever ever ever ever ever sleep on my side if I want to fix my shoulder pain

30. For a long time, I've been reading it's the left side…heart side! So, I start that way…but after my mid-sleep bathroom break, I seem to wake up on my right side!

31. Maybe this explains why only humans seem to get alzheimers — we're probably about the only mammal that are flat enough to sleep on our backs, aren't we?

32. What about an elevated head position, with something like a wedge pillow? Couldn't gravity help the glymphatic flow drainage process?

33. There's just a slight frustration in hearing this about back sleeping when there are others who have said that sleeping on the back is the best. Typically, it's for the benefit of the spine, as I recall. For most of my life, I've been a stomach sleeper. Unfortunately, I've suffered from both insomnia and spinal pain. For several years, I had little choice but to be a back sleeper. It was better than not sleeping at all, but I hated it. Whenever I've slept for extended periods on my back, I always woke up tired, and very slow and achy. I will say, laying on the back does seem to be the quickest way to get to sleep. I've tried side sleeping, and I'd be a left-side sleeper, but it always bothers my shoulder and hip. Best compromise I figured out was to sleep on my back with some pillows propping up one side for a bit of a tilt, a hybrid of side and back sleeping. Luckily, I figured out some dietary changes that alleviated my spinal pain and I was able to resume stomach sleeping after several years and that was huge. It just works for me. To reference Dr. Greger on cooking methods, the best sleeping position is the one that allows you to get the most quality sleep more often. For me, that will be stomach sleeping for the foreseeable future. I've given up trying to find something better for now. But this is a great topic and for those who can apply these changes, and if that really is ideal for sleeping, then it's a wonderful thing to learn.

34. Thank you Dr. Greger!!!

35. I sleep on my back. Why can’t I just turn my head to the side that wouldn’t work just as well.

36. Conclusion: sleep on your right side. You’re welcome!

37. I’m half deaf in my left ear so I always sleep on my right side. It’s like having ear plugs in. 10/10 would recommend.

38. Sleeping on your back with your head and shoulders raised up on a triangular shaped pillow is an excellent sleep position and helps to fight against glaucoma which occurs from sleeping on your side due to pressure on your eyes. Snoring occurs less on your back, allows sinuses to drain, helps align your spine and keeps one from getting headaches. If everything is draining well by sleeping on your back on an incline then it’ll help your brain drain as well. Not buying this article.

39. yes thank you for this video! finally someone has scientifically parsed through the data and explained it. bless your soul Dr. Gregor.

40. Yada yada yada, nothing makes any difference. If it actually worked, most everyone would feel it or at least know about it.

41. I used to sleep on my left side (left side faces the door) until I would wake up with terrible pain in my arm. I moved to the couch but I would frequently get a stiff neck. After a couple years on the couch and some yoga, I trained myself to sleep on my back. I can try my side again, but I fear the pain in my arm.

42. I get heart palpitations sleeping on my left. Wonder if its related 😮

43. Interesting, but you didn't really answer the question you posed regarding 'best sleeping position", or rather, you answered it in one sentence for right-handed people but nothing for left-handed people. Should it just be the opposite, i.e., left-handed are best off sleeping on their left side? You spent more time speaking about sleep duration than what side to sleep on and why. All good but just not much on the subject of the title subject. I know how long to sleep or not to sleep but not really on what side…..could you comment? thanks!

44. But what if you dont use a pillow? I’ve noticed then my overnight HRV increases if I sleep on my back.

45. so, in the other book, greger recommends trendellenburg for fat burning, will that sleeping position give you extra dementia?

46. Personal experience: sleep lab is a nightmare. Just try changing your sleep position a couple of times when you've got 20 wires and tubes connected to you. Somebody (some corporations) are making a killing.

47. I used to snore a lot and suffered from sleep apnoea. About 15 years ago, I read somewhere on the web that sleeping on your side could help against this so I started sleeping on my side. I haven't woken myself up by snoring or sleep apnoea since. Easy fix!

    I used to be groggy first thing after waking and get tired in the afternoon. I read a study in New Scientist a few decades ago that recommended between 6 and 7 hours sleep a night so I started having only about 6 to 6 ½ hours sleep. Since then I've been waking up feeling great and rarely feel tired through the day. If I do feel sleepy in the arvo, I have a siesta (if I'm able to!) which sorts that out. 🙂

48. I wonder if sleep apneas is the missing piece here? People tend to have more apnea events on their back. Apneas prevents people from going into deep sleep, which is when that brain clearing process can occur. People with apneas also sleep longer, because their bodies keep trying to get the deep/rem sleep they need.

49. "On your flank to not draw a blank!" Omg – XD XD XD

50. the conclusion is that there is not enough data?

51. improving the Glymphatic system, the Ayurvedic way.

52. Sleeping on the back also increases sleep apnea's severity, which may explain why sleeping on the side is better

53. Really? Animal testing?

54. Women are encouraged to sleep on their backs to reduce wrinkles on their face. I’ve never paid attention to that and switch between my left and right side. I’ll take the wrinkles to give me a healthier brain 😊

55. I love your videos, but please do not cite studies that involve animals. Thank you!

56. I picked up on the point from elsewhere (can't think where at the moment) that we actually developed a tendency to sleep on our left side, or our less dominant arm side, so we had a fighting chance to swipe at a creature or attacker that may have woke us with our strongest arm. Yet still, I would imagine having you heart higher up would be an advantage for efficiency, so surely the less common left handed people would have dealt a better blow if this was any kind of evolutionary advantage? But then having your heart further down was maybe a safer place… actually that rings a bell

57. Is Dr Gregor talking about actually sleeping for 9 hrs or more or about just lying in bed daydreaming after waking up after 7/8 hrs?

58. prophet muhammad said to sleep on the right side rather than on the stomach or back.

59. Okay, I’m doomed. I can only sleep on my back because of degenerated discs in my lower back. Because of this I also use a CPAP machine so I hope that helps me out some. But man, I’d like to be able to sleep on my side.

60. How is it that tic tok and other channels get so many likes and this channel which has such great information is not smashing it?

61. Great stuff.

62. More sleep could also be an adaptation from the brain because it knows that things are bad and more cleaning is needed on average.

63. Thank you very much for your valuable information ♥👍👍

64. Oh how I wish I had the problem of sleeping too long!!

65. Why does it seem like everyone of your videos you are giving us information in a tone like you are questioning what you are telling us? It sounds like you just don't know what you're talking about.

66. Well, I started sleeping on my left side consistently a few months ago when I got a new extra-firm mattress and could no longer sleep on my back; I'll try shifting to the right side—although the reason I've been sleeping on the left side is to muffle my good ear and have my tinnitus ear face up.

    Having had a traumatic brain injury in the past, this video is of particular interest to me, and I tweeted it earlier today!

67. Where does resistance training and cardiovascular training factor into the claims surrounding oversleep? When you exercise, you absolutely need more recovery time in bed. 8-8.5hrs a night is required and cognitive sharpness is most certainly felt from the influx of blood and oxygen to the brain from exercise. I cant imagine being at higher risk of cognitive decline relative to sedimentary individuals who average 7hrs of sleep per night

68. Thank you for this. It is a trade off possibly, considering that sleeping on one's right is worse for those who suffer from GERD (due to stomach positioning). Many over 65 have incompetent esophageal sphincters.

69. I think you are one of the WORST speakers I have ever heard. So phoney how you try to inject pauses, and "uh hum"s to make you appear to be more confident. It didn't work. Just makes you sound fake…like you must be?
