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.

Cons for poor sleep
1:35 Make us make risky, brash decisions
1:40 Reduces capacity for empathy (hence reduces emotional intelligence)
1:50 Pain tolerance decreases

2:12 3 stages of sleep-
1. Light sleep - brain waves similar to awake time
2. REM/Dreaming
3. Deep Sleep - long burst brain waves different than awake time called "Delta waves". Marker of biological youth. You lose deep sleep as you age. Most regenerative stage of sleep.

When don't get deep sleep - decreases ability to learn (inhibits conversion of working memory to long term memory)

3:55 Hacks for deep sleep-
1. Certain sounds at the right time in sleep. Also increases next day memory performance. Sounds with the same burst frequency as DELTA WAVES. Primes your mind to have more of these regenerative delta waves.

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 had the greatest sleep of my life or at least since childhood and will definitely do it again in the future.

I believe people really need this. Being a student in high school, I hear complaints about lack of sleep from most of my peers. Keep doing what you do.

Skip to 4:40 to avoid wasting time with facts you already know. Then you learn that a device yet to be marketed that matches the brain wave patterns of deep sleep may help achieve that stage.

I found out that if we sleep early like around (9-10 pm) the quality of sleep especially deep sleep Improves

[MrYakooboovsky]

That sound reminds me a sound of rain. It got his evolutionary causes in my opinion, when rain drops predators don't hunt so we can sleep deeper. I personally love to sleep when it's raining outside - air is so fresh and sound is so calming.

I recently turned 50 and I wake up every morning feeling like a 19-year-old gymnast as I swear by getting a nice dose of quality sleep, religiously!! It truly contributes to your fountain of youth!!

[PolishBehemoth]

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.

Play the video at 1.25x speed...so that you don't fall asleep while wacthing this video.

Edit: Am I famous now?
Should I write comedy?
So much potential 😜...
Thank you everyone for liking my comment!

sleep is really important, sleep is good, sleep is great.

-me at 4:30am

That explains why the sound of ocean waves is so calming. The best music for deep sleep.

[MargaretJeanCannon]

The sound that was discovered sounds like heavy waves -- I could definitely sleep with this sound! Sleep, and deep, restful sleep, is so critical to my health

[immortaler]

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.

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.

Finally, someone is doing something to improve sleep. I've had interrupted sleep since a Traumatic Brain Injury, so I've been sleep deprived for 17+ yrs despite extensive and expensive efforts to correct my issue. Can't wait to try this therapy!

[martinuhnak]

Such a good job by Dan with the preparation for this talk. Although you can sense nervousness, he overcame it effectively. Great talk about a compelling idea!

[cymonka]

This could very well be an effective way to combat aging. When we get older it takes longer to heal from injuries but to actually manipulate sounds to get more out of deep sleep which we lose as we age could mean we can recover faster from injuries more efficiently. I'm loving this.

[noviceprepper]

I hope this develops quickly. I have multiple sleep disorders and it makes life really difficult.

[ZaynabAslam]

I struggle with sleeping so much so I'm so glad there is more research happening on this
