The Paradox of Sleep with Matthew Walker & Neil deGrasse Tyson

Рет қаралды 554,318

Күн бұрын

What happens when we go to sleep? Neil deGrasse Tyson and co-hosts Chuck Nice and Gary O’Reilly break down the mystery of why we sleep, time dilation in dreams, circadian rhythms, and sleeping in space with neuroscientist Matt Walker.
Why did our need for sleep survive evolution? We explore the evolution of sleep and why we even need to sleep at all. Do all animals sleep? Learn about Nathaniel Klietman’s cave study, our 24-ish hour sleep cycle, and what the definition sleep even is. Does the early bird really get the worm?
What goes on in the body while we sleep? Discover the syphonic pulsing of brain waves that occurs in non-REM sleep and how REM sleep looks similar to waking. We discuss Alzheimer's relationship to sleep and new technology to manipulate sleep brain waves. Could you use technology to supercharge sleep so you could sleep for shorter periods? Can you really “catch up” on sleep? We explore the relationship between dreams and time and whether time really does move slower in the dream world.
How similar is sleep to a psychotic break? We discuss the hallucinations and premonitions in sleep and do a statistical analysis of Gary’s premonitions. Is there snoring in space? Find out about what makes sleeping in space tricky and whether Neil would be a good subject for a sleep study.

I can honestly say that professor Matt Walker is one of the best guests you ever had on Startalk! His level of knowledge and his way of communicating it is outstanding! I was mesmerized by him and also were Neil and Chuck, because they didn't need to interrupt as often or make funny remarks to keep the conversation going! Ironically, him talking about sleep made me pay more attention than ever! I'm a fan of Matt Walker!

This is just an anecdotal example, but my uncle was recently telling me about a coworker (they’re cops/detectives) who went insane from weeks or months of insomnia/sleep deprivation. He ended up going to a public pool and shooting himself in the face (I’m unsure if he was trying to commit suicide or what). My uncle told me this person had no history of mental health issues (their police department regularly requires mental health evaluations) and that it was determined to be momentary insanity related to sleep deprivation (this uncle worked in the office of internal affairs so I assume he was part of or privy to the investigation into the episode). Thankfully no one else was harmed and while he suffered grevious injuries, this person recovered his sanity with a return to a sleep schedule. Off the top of my head I’m unsure but I think this aligns with sleep deprivation studies conducted by russia and the us before stringent medical ethics were applied to human studies.

As a lifelong sleepwalker, I wish they had talked about it also. Sleepwalking became less frequent when I reached my late 20’s, but I still do it. It freaks out my partner, and I’m always freaked out the next morning if anything weird happened. It is very disconcerting, but at least it isn’t very frequent now, but it can be scary. I never remember what happens when I sleepwalk. Not a nanosecond. That is the most disturbing part, because I have zero awareness and zero control, as a result. I wish we knew how to make it stop.

Actually, sometimes it seems that the whole dream is set up to lead to that external sound, which during the dream still didn't happen, but will happen at the end of it. I had a few such experiences in my dreams. I was flabbergasted. Tho, it's probably that at the subconscious level I was already expecting that external sound to happen, and my brain calculated it into the dream, in advance.

@patola2292 6 ай бұрын

@@damyr Or maybe your ears perceived the sound, but on the electric impulse way in, before it reaches you and you became "aware" of it, the brain was able to fit in a whole dream, which, in turn, ends with you (finally) perceiving" that very sound. Does this make any sense? xD

Once, after dinner he poked his cheek with a toothpick, obviously missing his mouth, because he'd fallen asleep. My wife had never seen such a thing and thought it was the funniest. Dad was always good-natured about the incredible ease of his ability to fall asleep. After I learned about sleep apnea through a company I worked for, I encouraged him to get a sleep study.

Wild to hear sleep called a waste of time: sleep is one of my favorite things because dreaming is just absolutely amazing. Dreaming and lucid dreaming are where some of my favorite, most magical memories are made❤❤❤ I didn’t realize lucid dreaming wasn’t common until I was older (at least half of my remembered dreams are lucid dreams); I thought everyone’s parental figure had taught them to lucid dream so they could stop the reoccurring nightmares that plagued my early childhood. My mom taught me how to recognize you’re dreaming and control your dream because she was so tired of waking up to me screaming, and she told me her mom had taught her the same, her grandmother had taught her mother, etc etc. The problem with having such vivid dreams is that when they are mundane I can’t differentiate them from waking memories. Thanks for this episode!

It can also take a very dark turn and throw all sorts of 'stuff' at you that you've never physically encountered in places you've never been, and morph them into some quite horrific things and places in the blink of an eye.....not sure what practical everyday life problem solving that is, but it happens....... I get the impression that dreams are more like memories/thoughts/experiences from life, or films or TV all being jumbled up and you find yourself in the middle of whatever is being manipulated by your sleeping brain at the time, which is how you can be in multiple locations just by walking down a short street; it constantly changes as the stored 'data' is rushing past, and in the dream you 'see' it and 'feel' it. Maybe it's just your brain/mind trying to neatly file things away for future recall, but when I'm asleep it seems my mind keeps dropping the damn things as it's filing them..!! 😂 Whatever, it's a fascinating subject, and this was an absolutely excellent episode of StarTalk, and Matthew Walker was an excellent guest! 👍

At 10 years old I have never rode a 10 speed or anything that size before, never mind without holding the handle bars. Well the next day, day before Christmas, I got home from school earlier than my brother, dad was at work still and mom was out shopping, so I decided to take my brothers new Christmas present out for a cruise around the block. Within a half hour I was comfortable enough and riding around the 1/4 mile block with no hands! Even before he got to ride it lol. Great show and Neil is awesome!

In anthropology we hypothesize that there is an evolutionary advantage to the diversity in circadian rhythms. Within a hunter-gather band, which lives outside all the time, having different sleep cycles allows the band to sleep with someone on alert and on guard throughout the dangerous night and, thus, improves survivability of the band.

So because of the slower brain activity, we run slow in our dreams. I remember learning this. What's fascinating is in my dreams now, If I'm running when I notice it's slow, I simply acknowledge that it's dream running, and that's why it feels slow. I tell myself just go with it. The dream always ends after that, like me acknowledging it being a dream somehow stops the dream. I wish I could stop that happening and have lucid dreams, but it seems that I can't, or don't remember.

Great Episode, I think, because so many of us have a tough relationship with sleep and it’s a subject that we want to understand better. It also helped that Matt is so engaging and articulate.

Agreed with earlier sentiment, or at least that it *feels* like Sleep is time not being productive, despite knowing how much Sleep accomplishes for mental/physical health~

Never knew that it was "the" Gary O'Reilly. I'm a Palace fan and watched him in his youth, including the infamous semi final against Liverpool in 90. Good to see him doing well.

Haven't been tuning into these as much lately but I think I'll start doing so again, this one and one of the others a few days ago I really enjoyed (though Ironically I can't for the life of me remember the topic of the other one lmao) you guys always make educational content that is really enjoyable and consumable by someone like me with a interest in the topics but not necessarily in a science field and interested in the more clinical format for information (though I do understand that there is value to this style of presenting information too, both have a place in my opinion)

Great podcast! I've wanted to write a philosophical paper on sleep for some time now, and I was re-inspired by reading Matt Walker's book. From a philosophical point of view sleep is a very interesting subject because Philosophy tends to over-emphasize the importance of consciousness. The fact that we go to sleep every 24 hours demonstrates not only our body's connection to the earth's rotation but also our connection to life's primordial beginnings. The fact that we sleep for about eight hours every day means that one third of our lives is spent in unconsciousness. This implies that there are some necessary bodily processes that cannot work if we are conscious, or to put it another way, consciousness gets in the way of certain bodily functions. What are these functions? Probably resetting of our circadian rhythm, master regulation of our hormones, muscular skeletal growth, tissue repair, immune system regulation, and the making of permanent memory. This takes consciousness down a notch - it ain't the be all and end all if it needs to be shut off for one third of the time we are alive on this earth.

My natural circadian rhythm is on the early side. I spent 35 years of my life working a chaotic schedule of day, evening and night shifts. I always found the night shifts to be excruciatingly difficult. In the past 15 years I have been able to revert to my natural cycle. Looking back I really wonder how I survived those 35 years.

I was awoken early when my house alarm malfunctioned. I had to spend a few minutes opening it to disconnect the battery. I tried to get back to sleep and after 10-15 minutes had this moment of sleepy clarity where EVERY memory I chose to recall was instant and vivid. I could remember things clearly from events 30+ years ago. It was blissful.

I would love to see what Doctor Matthew Walker could learn and explain about my sleep patterns because I have learned that I am an oddity. I have always been considered to be an insomniac. I have extreme difficulties getting to sleep. I am easily disrupted from my sleep. In fact, I often don't need a disruption from my sleep because I seldom lose consciousness during my sleep. I tend to know that I am dreaming, can recall my dreams, can alter my dreams, and can keep track of and listen to those in my environment around me while I sleep and dream. Although, I do sometimes have to respond to those communicating with me during my sleep several times because I respond to them in my dream state, but then have to do so again as my response occurs within my brain and I realize that my body has not produced that response for them to hear.

My last 25 years before retirement I worked a 3rd trick schedule - would go to bed upon getting home and would only be able to get 4 or 5 hours of sleep - and never had any dreams that I could recall upon waking up. After retirement have a more normal night to morning sleep schedule and frequently wake up knowing that I have had one or more dreams.

Extremely interesting. I have central (brain) sleep apnea not to be confused with obstructive sleep apnea. When I sleep I make no effort to breath. I wake hundreds of times per night from oxygen deprivation that lasts 60 to 80 seconds each before I take a breath. Never having a long enough duration of sleep to even dream. Nor do I remember these hundreds of episodes of waking just long enough to get a single breath. I could not function. My CPAP machine literally saved my life. So I especially appreciate sleep study science.

Movement powers lymphatic system which carries the Lactic Acid (byproduct of 'work' that makes muscles sore) from muscles to brain, where it metabolized Only during REM Sleep... If you sleep a short time, not achieving REM, you'll wake up as sore as you were when you went to sleep. I was Army Infantry and Fire & Police. I'm very experienced at not getting enough sleep...

Great episode thanks guys. I would suggest that an ability to relax and sleep is the sign of a healthy nervous system free of trauma as well. Many folks can't switch off and there can be reasons such as trauma and abuse sitting behind that from earlier years.
