Why Sleep?: Matthew Walker's CNS 2019 Keynote

Can you recall the last time you woke up without an alarm clock feeling refreshed, not needing caffeine? If the answer is “no,” you are not alone. Two-thirds of adults fail to obtain the recommended 8 hours of nightly sleep. You may be surprised by the consequences, which Matthew Walker (University of California, Berkeley) describes in his keynote for the 26th annual Cognitive Neuroscience Society annual meeting. His talk describes not only the good things that happen when you get sleep but also the alarmingly bad things that happen when you don’t get enough. He discusses the brain (learning, memory aging, Alzheimer’s disease, education), and highlights disease-related consequences in the body (cancer, diabetes, cardiovascular disease). The take-home: Sleep is the single most effective thing we can do to reset the health of our brains and bodies.

I appreciate that Matt takes questions so well, and actually answers the questions without drifting away

He sleeps very well each and every night. That’s why Matt doesn’t drift on the questions...

It’s definitely a bigger problem then just adjusting the times of school. We need to completely rework our social system. From school start times to work start times, and work duration times. We need to be affective with a smaller window of time rather than thinking working more hours attributes to better work and more money. Horrible way we’ve gotten into.

[@AngelaSealana]

Yes! I wish I could get to work at 10am because of my sleep needs 🥲

[@cfoster6804]

I think a 6 hour workday is better. That's usually when my mind checks out on any job.

Suggestion that a key part of the need for sleep is the body's need to make serotonin, which it does in a symbiotic relationship with gut bacteria in the large intestine. We sleep to first produce serotonin, then to draw it into the body through the extraction of water in the large intestine. Though it can be synthesized, there seems to be a major difference in the health benefits from the micro made serotonin, and the artificially made serotonin. Here's some notes on both how important serotonin is and how widespread it is in all living things. Besides mammals, serotonin is found in all bilateral animals including worms and insects,[19] as well as in fungi and in plants.[20] Serotonin's presence in insect venoms and plant spines serves to cause pain, which is a side-effect of serotonin injection.[21][22] Serotonin is produced by pathogenic amoebae, and its effect in the human gut is diarrhea.[23] Its widespread presence in many seeds and fruits may serve to stimulate the digestive tract into expelling the seeds.[24] Gut bacteria manufacture about 95 percent of the body's supply of serotonin, which influences both mood and GI activity.

[@michelewood775]

Thank you for the educational video. No one talks about menopause and how it wakes women up all night long with a timed hot flash compared to a contraction every 2 hours on the minute all night long, and for 10 years! How can I get a good 8 hours of sleep? How is this in the world of sleep and aging, and memory loss, and what can we do about it? I miss sleeping!

[@ghazalehjalai5648]

you are prefefecttttt

[@deepakkapurvirtualclass]

In the waking state, thoughts come 'automatically' in our minds. For example, i myself don't know what thought will come into my mind say after 10 minutes, 20 minutes etc. When thoughts come automatically to our mind, it 'seems' to us that we have consciouly 'thought' them. Similarly, while sleeping also thoughts come 'automatically' to our minds.

[@TomHendricksMusea]

Wonder about the affect of serotonin. This is made in virtually every plant and animal. It has massive benefits, and it may be directly connected to or helped made by our micro biome in the gut during sleep. It may be so important that it's the reason living things sleep.

[@ariel6999]

One thing I thought was a bit manipulative was the chart of the minnisota school start time.. the scale of the graph was visually manipulative

[@ameyjangam2485]

So to get a goodnight's sleep you need silence around you. But there is a thing called as hypnotherapy hence, does it affects your sleep?

[@Cl4rendon]

Meanwhile with 57 i only have a good sleep quality during the transitional seasons Spring & Autumn. Summer ( too hot ) and Winters ( Light & vitamin D deprivation) mess up my sleeping patterns. In Winter it`s the worst meanwhile.

[@fVNzO]

You can easily fix vitamins and lighting? And in the summer you could invest in cooling. Both are fixable.

[@conan7080]

You're fine. Sleep experts actually hate this guy for the misinformation he has spread. Most people sleep between 6 and 7 hours. If you feel good on 6 and a half, that's what your body needs. You can't force yourself to sleep longer than your body requires

The medical industrial complex's failure to properly research and diagnose and treat microbiome and sleep and vital nutritional deficiency issues (including those related to Vitamin D3 and Vitamin K2 and Magnesium deficiencies as well as iatrogenic prescription medication usage) is a major reason why psychiatric iatrogenesis is a primary contributor to the third leading cause of death in the U.S. (which is iatrogenesis in general). If the U.S. spent just a fraction of the over $40 billion each year it spends just on iatrogenic psychiatric drugs alone, on properly researching the issues discussed in this and related KZbin presentations we would probably, Lord willing, achieve an absolute revolution in medical efficacy improvement and iatrogenesis reduction.

Regarding your part on jet lag, there has been an experiment that linked food depravation and coping with jet lag. Don t eat 1 hour before you go to the airport, don t eat on the way to the airport, don t eat in the airport, don t eat on the plane. Eat at the first meal time when you land. This is how you cope with jet lag and I am a little disappointed that you stated in the course that there is no cure for jet lag. Please do your research before making bold claims regarding no cure for jet lag. Thank you.

Not everyone. Most layperson do not and cannot simple get all those hrs of sleep. Why? Because of life. Maybe in a perfect world or controlled life where everything is given and our only job is to sleep. If my job was to sleep then I would do it well. Not going to happen this lifetime. Maybe develop a pill that enhances thought process and memory retaining. Maybe use A.I. to better human?

[@RolandKoller90]

You definitely missed the point of this very informative talk. We need to fight for our sleep. Fight against society who thinks we should work all day, or work that overnight job. Money is a terrible motivator sometimes. I recently quit my job because it was stressing me out too much. Work from morning until late evening, it threw off my whole life.
