Sleep may be the most overlooked factor in America's declining productivity and wellbeing. Drawing from Sarah Mednick's eye-opening book "Take a Nap, Change Your Life," this episode explores how modern life has dramatically altered our relationship with rest and the profound consequences this shift has had on our collective performance.

The statistics are startling. Before Edison's lightbulb illuminated our nights, our ancestors routinely enjoyed 10 hours of rest during average weeknights. Today, we struggle to achieve 6.7 hours, creating a nation of chronically exhausted individuals. Over half the workforce reports that sleepiness interferes with their productivity, while one in five adults experiences fatigue that disrupts daily activities multiple times weekly.

While we search for complex explanations for America's declining global competitiveness, falling educational performance, and deteriorating health outcomes, we consistently overlook a simple factor: we're exhausted. Once the world's most productive workforce, the United States has slipped behind countries like France and Germany by numerous measures. Our standard of living is declining, our technological edge eroding – and chronic fatigue may be a significant culprit.

The solution is refreshingly straightforward: sleep more. Put down your phones, reduce screen time, and prioritize rest. As Mednick notes, if you need caffeine to stay awake, you're not getting enough sleep. By reclaiming our natural sleep patterns and incorporating strategic rest periods, we can reverse the tide of exhaustion undermining our potential both individually and collectively.

Ready to transform your productivity and wellbeing? Start tonight by setting aside your devices earlier and giving yourself permission to rest. Your mind, body, and work will thank you tomorrow.


Key Points from the Episode:


• 51% of workers report that sleepiness interferes with their work performance
• One in five adults experiences fatigue that disrupts daily activities multiple times weekly
• The United States has fallen behind countries like France and Germany in productivity
• Sleep deprivation is an overlooked factor in America's declining competitive edge
• Sarah Mednick's book "Take a Nap, Change Your Life" offers a simple solution: sleep more
• Needing caffeine to stay awake is a clear sign you're not getting enough sleep
• Reducing phone screen time before bed can significantly improve sleep quality

Put down your phones and get more sleep. I promise we'll all be better off for it.

00:00:07.612 --> 00:00:20.807
Welcome to the Theory to Action podcast, where we examine the timeless treasures of wisdom from the great books in less time, to help you take action immediately and ultimately to create and lead a flourishing life.

00:00:20.807 --> 00:00:24.850
Now here's your host, david Kaiser.

00:00:27.839 --> 00:00:29.484
Hello, I am David and welcome back to another Mojo Minute.

00:00:29.484 --> 00:00:32.731
As is our custom, let's begin with the opening quote.

00:00:32.731 --> 00:00:44.823
Before Thomas Edison's light bulb, our great-grandparents would get as much as 10 hours of rest during an average weeknight.

00:00:44.823 --> 00:00:49.107
Today we're lucky to get eight hours on the weekend.

00:00:49.107 --> 00:00:57.454
The amount of actual weeknight slumber has shrunk on average to an alarming 6.7 hours.

00:00:58.475 --> 00:01:11.670
We are a nation of the walking tired, so much so that 51% of the workforce reports that sleepiness on the job interferes with their volume of work they can do.

00:01:11.670 --> 00:01:23.409
One in five adults is so sleepy that it interferes with his or her daily activities a few days a week, while an additional 20% report impairment a few days a month.

00:01:23.409 --> 00:01:35.522
Once the nation with the most productive workforce in the world, the United States, by a number of measures has fallen behind countries such as France and Germany.

00:01:35.522 --> 00:01:45.891
Our standard of living is slipping, our students are underperforming and our collective health is deteriorating.

00:01:45.891 --> 00:01:50.364
In areas such as science and technology we no longer dominate.

00:01:50.364 --> 00:02:07.575
Politicians, pundits, experts from all fields have made an industry out of explaining what's going wrong, but they continually overlook the role of that quiet little demon, fatigue.

00:02:07.575 --> 00:02:13.229
And that quote comes to us from a nifty little book.

00:02:13.819 --> 00:02:20.713
Sarah Mednick wrote the book called Take a Nap, change your Life.

00:02:20.713 --> 00:02:25.050
Her big idea if you want to change your life, take a nap Seriously.

00:02:25.050 --> 00:02:33.653
She says almost all of us listen to me, almost all of us are sleep deprived.

00:02:33.653 --> 00:02:45.551
In fact, if we go back to that quote, before Thomas Edison's light bulb, our great grandparents would get as much as 10 hours of rest during the average weeknight.

00:02:45.551 --> 00:02:50.725
Think about that 10 hours of rest every night.

00:02:50.725 --> 00:02:54.671
Sun goes down, lights are out.

00:02:54.671 --> 00:02:56.193
Why?

00:02:56.193 --> 00:02:58.221
Because there were no lights.

00:02:58.221 --> 00:03:09.984
Thomas Edison's light bulb doesn't come in until 1875, and it's not really throughout the United States until well into the 20th century.

00:03:09.984 --> 00:03:12.388
That's crazy.

00:03:14.030 --> 00:03:19.963
Back in the day I used to say with macho man gusto, I can get by with only six hours sleep.

00:03:19.963 --> 00:03:24.491
And as I get older that's just simply not true.

00:03:24.491 --> 00:03:25.932
I don't do my best work.

00:03:25.932 --> 00:03:27.014
I need more caffeine.

00:03:27.014 --> 00:03:32.512
And even she says in the book if you need caffeine to stay awake, you're not getting enough sleep.

00:03:32.512 --> 00:03:36.270
And the solution is simple Sleep more.

00:03:36.270 --> 00:03:40.409
I know it's very hard to do, but we should try.

00:03:41.941 --> 00:03:47.413
So in today's Mojo Minute, can we begin stop scrolling on our phones?

00:03:47.413 --> 00:03:51.912
You know, there's only so many Facebook reels that are productive.

00:03:51.912 --> 00:04:02.725
There's only so many news programs that you can keep up with as the world changes by the hour and, frankly, most of us.

00:04:02.725 --> 00:04:11.170
There's nothing you or I can do about any of it, unless you're the president of the United States, you don't have a say.

00:04:11.170 --> 00:04:15.711
So instead, let's put our phones down and get some more sleep, shall we?

00:04:15.711 --> 00:04:18.708
I promise we'll be better off for it.

00:04:18.708 --> 00:04:24.853
And if you can't get to sleep, well then here's a nifty idea to keep using that word.

00:04:24.853 --> 00:04:35.790
Put on this podcast, put it on in a low murmur and by the end of it you will be catching Z's like Fritz the night owl.

00:04:35.790 --> 00:04:39.384
And if you don't know who that is, google him.

00:04:39.384 --> 00:04:41.588
He's a pretty cool cat.

00:04:41.588 --> 00:04:42.329
Look him up.

00:04:42.329 --> 00:04:47.244
Seriously Cool cat, as always.

00:04:47.244 --> 00:04:48.769
Keep fighting the good fight.

00:04:52.781 --> 00:04:54.007
