00:00:00So let's talk about how to apply quality
00:00:01peer-reviewed science to your day
00:00:03and how to optimize everything from sleep to learning,
00:00:06creativity, meal timing, et cetera.
00:00:09I'm going to do this in the context of my day
00:00:11and what I typically do.
00:00:13So let's start with getting up in the morning.
00:00:15Now for me, I tend to wake up sometime around 6 a.m.,
00:00:206.30, sometimes as late as 7 a.m.
00:00:22I don't typically sleep much later than 7 a.m.
00:00:25The first thing I do after I wake up
00:00:27is I take the pen that's on my nightstand
00:00:30and the pad of paper on my nightstand,
00:00:31and I write down the time in which I woke up.
00:00:34Now, I do sleep with my phone in my room.
00:00:36I realize this is considered a sin
00:00:38and has certain hazards associated with it.
00:00:41But I put my phone on airplane mode
00:00:43about an hour before I go to sleep.
00:00:45And then I set my alarm typically for 6.30 a.m.
00:00:47And some days the alarm wakes me up.
00:00:49Other days I wake up before the alarm.
00:00:51And yes, some days the alarm goes off
00:00:53and I hit snooze a few times.
00:00:55And then usually by 7 a.m., I am up and out of bed.
00:00:58The second thing I do after I wake up
00:01:00is to get into forward ambulation,
00:01:03which is just nerd speak for taking a walk.
00:01:06I have a dog, and as many of you know, he's a bulldog,
00:01:09and he doesn't really like to walk,
00:01:11especially not in the morning.
00:01:12But for humans and for animals,
00:01:15there's a phenomenon whereby when we generate
00:01:18our own forward motion, forward ambulation,
00:01:21visual images pass by us on our eyes,
00:01:24so-called optic flow.
00:01:25And for those of you that are low vision or no vision,
00:01:27the same phenomenon occurs in the auditory system.
00:01:30Sounds pass by us in so-called auditory flow.
00:01:34Getting into a mode of forward ambulation
00:01:37and especially experiencing visual flow
00:01:41has a powerful effect on the nervous system.
00:01:43The effect it has is essentially to quiet
00:01:46or reduce the amount of neural activity
00:01:48in this brain structure called the amygdala.
00:01:50Amygdala means almond.
00:01:52And many of you have probably heard about the amygdala
00:01:55for its role in anxiety and fear and threat detection.
00:01:58And indeed, the amygdala is part of the network in the brain
00:02:02that generates feelings of fear and threat and anxiety.
00:02:05It does a bunch of other things too,
00:02:06but that's one of its primary functions.
00:02:08There are now at least half a dozen quality papers
00:02:11published in quality peer review journals
00:02:13that show that forward ambulation,
00:02:16walking or biking or running,
00:02:18and generating optic flow in particular
00:02:20has this incredible property of lowering activity
00:02:23in the amygdala and thereby reducing levels of anxiety.
00:02:26So for me, this process of taking a walk each morning
00:02:29isn't about exercise.
00:02:31It's not about burning calories.
00:02:32It's not about any of that.
00:02:34It's really about getting into optic flow
00:02:36and reducing the levels of amygdala activation.
00:02:39Now, I don't have anxiety.
00:02:41At least I don't have chronic anxiety or generalized anxiety.
00:02:45I tend to have a lot of energy,
00:02:46but at these points in the morning, I'm not very energetic.
00:02:49Sometimes I'm sort of shuffling more than I'm walking,
00:02:52in fact, and Costello is almost always shuffling
00:02:54and I'm almost always trying to drag him
00:02:55first thing in the morning.
00:02:57But that walk is a particularly important protocol each day
00:03:01because it really serves to push my neurology
00:03:04in the direction that I'd like it to go,
00:03:06which is alert but not anxious.
00:03:09And it's kind of a fine line sometimes,
00:03:10especially as events surface throughout the day,
00:03:13emails come in, text messages come in,
00:03:15get bombarded with a number of things.
00:03:17I want to be alert and responsive.
00:03:19I want to be able to focus,
00:03:21but I don't want to feel anxious or reactive to these things.
00:03:25So the forward ambulation and this optic flow
00:03:29is the way that I ensure, based on quality peer review data,
00:03:33that my amygdala activation is slightly suppressed.
00:03:36Now, at the same time, I also want the alertness.
00:03:39I want alert and focused.
00:03:41I don't just want to be sleepy or super, super relaxed.
00:03:45I want to have a high degree of focus and alertness
00:03:47because I'm soon going to move into about a work.
00:03:50I need to lean into the day.
00:03:52So in order to do that,
00:03:53I make sure that the walking is done outdoors.
00:03:57That might be sort of a duh,
00:03:58but many people get up
00:03:59and start moving around their house, their apartment,
00:04:01and they don't go anywhere.
00:04:02And just walking around inside,
00:04:04it will generate some optic flow,
00:04:06but nothing like the sort of optic flow
00:04:08that you can generate in larger environments
00:04:10like out of doors environments.
00:04:12Now, in order to get the alertness,
00:04:14I do it outdoors because I also want sunlight in my eyes.
00:04:17I know many of you have heard me talk about this ad nauseum
00:04:20on various podcasts and this podcast,
00:04:22but getting sunlight in your eyes first thing in the morning
00:04:25is absolutely vital to mental and physical health.
00:04:29It is perhaps the most important thing
00:04:31that any and all of us can and should do
00:04:33in order to promote metabolic wellbeing,
00:04:36promote the positive functioning of your hormone system,
00:04:39get your mental health steering in the right direction.
00:04:41There are a number of reasons for this,
00:04:43but before I get into those reasons,
00:04:44let me just emphasize what the protocol is.
00:04:47The protocol is get outdoors,
00:04:50ideally with no sunglasses if you can do that safely,
00:04:52even if there's cloud cover.
00:04:54More photons, light information
00:04:55are coming through that cloud cover
00:04:56than would be coming from a very bright indoor bulb.
00:05:00So getting outdoors is absolutely key.
00:05:01How long should you do this?
00:05:03It's going to depend on the brightness of the environment.
00:05:05It's going to depend on a number of different factors.
00:05:07Two minutes would be a minimum.
00:05:0910 minutes would be even better.
00:05:11And if you can, 30 minutes would be fantastic.
00:05:14So getting outside for a 10-minute walk or a 15-minute walk
00:05:18will basically ensure that you're getting
00:05:20adequate stimulation of these neurons in the eye
00:05:22that are called the melanopsin
00:05:23intrinsically photosensitive ganglion cells.
00:05:25I know that's a mouthful.
00:05:27These are neurons that don't care about shapes of objects
00:05:29or the motion of objects.
00:05:30These are neurons that convey to the brain
00:05:33that it's daytime and it's time to be alert.
00:05:35And it sets in motion a huge number of biological cascades
00:05:39within every cell and organ of your body,
00:05:42from your liver to your gut, to your heart, to your brain.
00:05:44It really sets things down the right path.
00:05:47So then Costello and I get back from our walk.
00:05:50Sometimes that walk was 10 minutes.
00:05:52Sometimes it was 60 minutes,
00:05:53depending on how slowly Costello was walking that day.
00:05:56Indeed, we get back.
00:05:58I give him his food.
00:05:59I give him his water.
00:06:00And I give me my water.
00:06:02I'm a big believer based on quality peer review data
00:06:05that hydration is essential for mental performance.
00:06:09Now, I confess I don't really like drinking big glasses
00:06:12or big jugs of water first thing in the morning.
00:06:13I don't know why,
00:06:14but my thirst doesn't tend to kick in first thing.
00:06:16Either way, I force myself essentially to drink at least 16
00:06:20and most days, 32 ounces of water.
00:06:23I also put a little bit of sea salt in the water.
00:06:26As many of you know, neurons require ionic flow.
00:06:29What that means is neurons need sodium,
00:06:32they need magnesium and they need potassium
00:06:34in order to function.
00:06:35We do tend to get dehydrated at night.
00:06:37Even if the day is not very hot,
00:06:39I try and top off or I try and make sure
00:06:42that I'm hydrated early in the day before I begin any work.
00:06:46So I make myself drink this water
00:06:48with a little bit of sea salt.
00:06:49How much sea salt?
00:06:50If you really want to get detailed,
00:06:52I suppose it's about half a teaspoon.
00:06:53It's not much.
00:06:54At that point, I start thinking about
00:06:56and fantasizing about and craving caffeine,
00:06:59but I don't drink that caffeine yet.
00:07:01I purposely delay my caffeine intake
00:07:06to 90 minutes to 120 minutes after I wake up.
00:07:09Of course, I know when I wake up because I wrote it down,
00:07:11although it's pretty easy to commit to memory.
00:07:13The reason I delay caffeine is because one of the factors
00:07:17that induces a sense of sleepiness
00:07:20is the buildup of adenosine.
00:07:21The buildup of adenosine accumulates
00:07:25the longer we are awake.
00:07:26So when I wake up in the morning,
00:07:28when you wake up in the morning,
00:07:29your adenosine levels are likely to be very low.
00:07:33The reason for delaying caffeine intake 90 minutes
00:07:35to two hours after waking is I want to make sure
00:07:39that I don't have a late afternoon
00:07:41or even early afternoon crash from caffeine.
00:07:44Delaying caffeine in 90 minutes to two hours
00:07:46optimizes this relationship between adenosine
00:07:49and wakefulness and sleepiness
00:07:51in a way that really provides a nice consistent arc
00:07:55of energy throughout the day and brings energy down
00:07:57as I'm headed toward sleep and falling asleep.
00:08:00My primary objective early in the day
00:08:04is to get into a mode of being focused yet alert
00:08:06so that I can get work done.
00:08:08I found that the best way for me to achieve that state
00:08:10is through fasting.
00:08:12So I don't eat anything until about 11 a.m. or 12 noon.
00:08:16Fasting increases levels of adrenaline,
00:08:19also called epinephrine in the brain and body.
00:08:22And when our levels of epinephrine and adrenaline
00:08:24are increased, we learn better, we can focus better.
00:08:27There's terrific data supporting that.
00:08:29Adrenaline really provides a heightened sense of focus
00:08:33and the ability to encode, meaning bring in,
00:08:36and retain, remember information.
