The brain benefits of deep sleep -- and how to get more of it | Dan Gartenberg

There's nothing quite like a good night's sleep. What if technology could help us get more out of it? Dan Gartenberg is working on tech that stimulates deep sleep, the most regenerative stage which (among other wonderful things) might help us consolidate our memories and form our personalities. Find out more about how playing sounds that mirror brain waves during this stage might lead to deeper sleep -- and its potential benefits on our health, memory and ability to learn.

Last summer I went for a big hike of 3 weeks. Just walking in nature, very limited if none access to internet for a few days or more, just walk all day, eat, set the tent, sleep and repeat.

I slept so wonderful that I woke up with the first rays of the sun, like a thousand years later. I didn't even know where I was. It's a gradual wake up. Só wonderful. I just woke up listening to the sounds of nature, birds and the tropical rainforest. It was amazing 🤩🤩🤩.

Literally the first thing that came to mind with the sound was "waves breaking on the sand". Lol it's so interesting to see other people in comments who thought the same. I went to massage school and one thing we learned is that sounds of nature relax us. It's like a subconscious feeling that things are ok: waves, birds chirping, rain drops. It just goes to show u all should incorporate more nature in your life to get better sleep.

I usually have 1.5-2 hours of deep sleep at best. Recently I made a goal to learn every day at least one hour of soft programming which really puts my mind to work in a way that never worked before. Long story short, I noticed my deep sleep started to be longer , jumped to 3-4 hours from the moment I started learning one hour per day. I think there is a connection between learning and deep sleep. Keep in mind I do my learning before sleeping time. I'm learning, then I have around 30 minutes of other activities like you tube, and then fall asleep.

[@franklinuvere9461]

It sounded more to me like when a mother breathes upon or around her child as they both sleep together in the same bed, cuddled up. Nothing, I can imagine, can evoke this experience of a deep sleep in any human being like the 'replay' of the experience of being cuddle up with one's mom, the greatest place of safety and reassurance, as a baby again. It also explains why we are likely to get better sleep when sleeping next to someone who loves us and whom we love in return. I suppose it's something like two hearts beating together in a synchrony that is reflected by the sound of each other's breath as it bursts forth, intermittently, into the ear of the other person, evoking the peace and tranquility that can only be experienced under those circumstances. I believe that this sound, though not 'heard' or 'perceived' by the participants as such, produces the reinforcing burst or signal of waves that increase the manifestation of the Delta waves that are produced and recorded during the period of deep sleep.

[@assassinaria]

I have a pillow that I brace my back against while sleeping on my side. It definitely gives me the same feeling as sleeping next to my Mom as a kid.

[@joel60551]

⚠️ Just a word of Caution ⚠️: the study of Gartenberg and similar ones played this noise at specific moments. Outside of a sleep lab, using audio stimulation without the proper equipment, you may do more damage than good. As he talked about in the TED talk these researchers try to play the noise right at the peak of the brainwaves measured by the EEG. If the same noise is played just a little bit off those natural peaks, it disrupted the sleep quality of the subjects studied. So just playing the sound is unlikely to help you sleep better, as your brain waves may peak at different times than the ones that were used to inspire the sound bite played here. For more examples look up an EEG graph of a deep sleep (stage 4) cycle. You’ll see that the deep sleep delta waves are not always consistently spaced. So one general sound is unlikely to work. Getting a full 5 to 6 sleep cycles, or 7.5 to 9 hours of sleep is still the best cure. If that doesn’t help seek out a specialised sleep professional.

[@SaHaRaSquad]

Yep, sounds like white noise with the volume changing rhythmically. I guess flooding the brain with such a broad spectrum of frequencies in the right manner could "sync" the brain waves to that sound and so make the deep sleep more efficient or something. At least that's how I imagine it.

[@faiza7533]

Chris Fokjohn They do sound like waves hitting the shore! No wonder I seem to sleep better in beach resorts.

SaHaRaSquad makes sense being that everything we listen to around us on a daily basis holds certain frequency that can be exactly determined on a frequency chart👌🏽

I don't think pink or white is important. It is probably the pulsations of it that are thought to drive Delta waves since they occured about as fast as delta waves--somewhere between 1 every two seconds and 4 per second.

[@llicit1833]

I have the iOS app. Ideally the deep sleep sound would play when your phone or some connected device detected that you were entering the deep phase. As it is, the sound starts 2 hours from when you go to sleep - so plays just once as far as I can tell. Like other commenters on here I look forward to an Android version (bought a beat up early model iPhone just so I could use this app)

[@stevejordan7275]

How does it tell when you're in delta phase sleep without being wired for EEG? I know my Connect app (Garmin tells me how much "deep" sleep I got, but I don't know how it knows.) Epistemology!

I made this as a kludge: kzbin.info/www/bejne/a6Kog2yGd9CgiNk Half an hour to fall asleep, five minutes of fade-in, and then seven hours of the delta synch sound with fade out at end.

[@DeepSleepFR]

It is really interesting, but it would be better to get more deep sleep as naturally as possible (without "wearing a small device"). Imagine that you go camping, spend the night in a hotel or at a friend's house and that you forget to take your device. Or even worse, if it has been dropped or damaged and it does not work anymore. How to fall asleep ? Some light sleepers unfortunately suffer from insomnia. Actually, if you fall asleep in a totally silent environment, you might "wake up with a start" at the slightest sound. A temporary solution to this problem is to get used to sleeping with "white noise" (e.g. fan sound, waves sound, rain sound, ASMR, etc.) However, in most cases, the real source of sleep problems and insomia are concern, worries, stress or anxiety and find out and solve those problems may be THE solution.

Where can we find an app/device that produces the sound at the correct time, frequency, intensity etc?

[@bestpranksters8424]

I'm wondering this too as it sounds like some sort of white/brown/noise or a combo. I'm also wondering if the alternating on/off like they played in the video is necessary, or if the sound played continuously has the same benefit?

[@inkisblackiswhiteis1]

sounds like I'm at the beach

[@Gdhdjejgfsbh]

That sound is quite similar raining at night . That's why I sleep so well when it's raining at night .

Watching this on a monday at work after a bad night sleep.

[@bambangruslihadi7073]

I know I'm in a deep sleep when I see Adele rolling

[@patrickssj6]

How do you know that the sound is improving the delta wave activity and not just stimulation the brain as a whole (e.g. sound processing, filtering-> is the sound I am hearing dangerous?)? They should have mada a negative test with a different sound.

[@kevinhart4real]

Good point. :)

[@jarfuloflove7320]

Would stimulating the brain as a whole cause delta waves?

[@patrickssj6]

to add to that question: Is the signal isolating delta waves or detecting overall brain activity?

[@Theminecraftboses]

I think that he simplified his research as he tried many gadgets and methods before this “breakthrough”. Although, I do see possible error as the test subject had not experienced the same attempts that he had. I guess if it worked on his the data would indicate his desired result better.

[@AmirianoAvenicci]

Because stimulating the brain would not increase delta wave activity, it would increase beta wave activity. Delta waves are correlated with deep sleep rather than wakefulness like beta waves.

I have a white noise machine sounds very similar without the burst mode. It does help me sleep as I am not distracted by noises in my environment.

WE HAVE TO GO DEEPER!

Earplugs will produce this sound. Your heartbeat creates the frequency and the static noise is generated automatically with the earplugs. Problem solved. Grant please!

[@ryccoh]

My ears hurt from years of wearing ear plugs every night :(

[@fionafiona1146]

Cuddling my boyfriend helps too, though I always blamed my moms habit of baby waring for my affinity for cosleaping

[@A.I.-]

I used the earplugs the other night. Next morning I was late to work because I didn't hear my alarm clock go off. I had a good sleep though. On a serious note. I've been using earplugs for several years now (only on Friday and Saturday nights). It is also a cheap alternative for sensory deprivation. Put a sleeping mask and earplugs, you're good to go and let the natural rejuvenation begin.

[@360.Tapestry]

i use moldable silicone earplugs (mack's brand), so i don't have any ear pain - just google it. my ears are not waxy, so they last about a month each. i also use an old blackberry-style phone under my pillow with the alarm set to vibrate - it's also great because i can program MULTIPLE alarms for specific days or repeat schedules, etc

[@SuperToughnut]

Kryptonite I use Mack's too. However I replace them every other day even though my ears aren't waxy.

[@erex9875]

Lmao is this why I can never fall asleep without a fan

[@iahelcathartesaura3887]

Yeah I was feeling like the sound he played matches our sleeping brain :)

[@keithcheng4671]

thanks for advertising your product

[@isaacnewton7424]

We all are watching it at night, right? What a coincidence.

[@eb6195]

Yes, KZbin algorithm ensures that.

[@calebsong9717]

I feel weirdly familiar with the sound. Like I already knew it without knowing it. It’s creepy.

[@smartcatcollarproject5699]

I can hear that sound when in complete silence... blood circulation in my ears, heart beat...

[@ppmireless]

That sounds like the ocean waves... Is that why I love ocean front rooms?

[@saideepps2920]

5:14 sounds like the waves 🌊
