Greetings, curious mind tuned to the world’s quieter truths.

This edition, we’re diving into a deeply human mystery: sleep.

How much we get—and don’t—varies wildly across countries and cultures. But this isn’t just about feeling rested. Sleep shapes productivity, health, even national economies.

So where is rest a cultural right—and where is it slipping away?

Let’s pull back the covers and take a wide-awake look at the global sleep divide.

Learn from this investor’s $100m mistake

In 2010, a Grammy-winning artist passed on investing $200K in an emerging real estate disruptor. That stake could be worth $100+ million today.

One year later, another real estate disruptor, Zillow, went public. This time, everyday investors had regrets, missing pre-IPO gains.

Now, a new real estate innovator, Pacaso – founded by a former Zillow exec – is disrupting a $1.3T market. And unlike the others, you can invest in Pacaso as a private company.

Pacaso’s co-ownership model has generated $1B+ in luxury home sales and service fees, earned $110M+ in gross profits to date, and received backing from the same VCs behind Uber, Venmo, and eBay. They even reserved the Nasdaq ticker PCSO.

Some nations sleep longer—and better—than others, and the differences are surprisingly stark.

🇳🇱 The Netherlands, 🇳🇿 New Zealand, and 🇫🇮 Finland lead the world in average sleep time, logging 7.5+ hours per night. Low stress, high life satisfaction, and smart urban design play key roles.

On the flip side, 🇯🇵 Japan, 🇸🇦 Saudi Arabia, and 🇰🇷 South Korea struggle with chronic sleep deprivation. Work hours run long, and sleep often loses out to tech time or late-night socializing.

📊 Powerful contrast: A person in Finland averages nearly 1 hour more sleep per night than someone in Japan. That adds up to 15 extra days of rest each year.

America’s sleep inequality mirrors its economic one.

Around 1 in 3 U.S. adults aren’t getting the recommended 7 hours. But where you live matters:
🟢 Vermont and Colorado report strong sleep averages and public health.
🔴 Mississippi and West Virginia, by contrast, report the worst—alongside high rates of chronic illness.

Sleep isn’t just personal—it’s economic. Sleep deprivation costs the U.S. an estimated $411 billion per year in lost productivity, accidents, and healthcare.

⚠️ Eye-opener: Fatigue causes 100,000 crashes annually in the U.S.—a preventable hazard hiding in plain sight.

What if your national work ethic was costing you sleep—and health?

🇯🇵 Japan has one of the lowest sleep averages in the world, with less than 6.5 hours per night. Long commutes and relentless office culture make rest feel indulgent. It’s so normalized that public napping (inemuri) is seen as a badge of effort.

Meanwhile, 🇸🇪 Sweden and 🇩🇰 Denmark embrace work-life balance: flexible schedules, early finishes, and family time. Unsurprisingly, citizens there report high sleep satisfaction and fewer disorders.

🌓 Interesting angle: Some workplaces in 🇮🇸 Iceland adjust hours in winter to account for extreme darkness, boosting both morale and rest.

Nature plays a role too—especially when it comes to light.

In equatorial countries like 🇮🇩 Indonesia, daylight hours are consistent year-round. That regularity helps support stable circadian rhythms.

But in higher latitudes like 🇸🇪 Sweden and 🇨🇦 Canada, sunlight can swing wildly with the seasons. During long winters, sleep can be thrown off—leading to seasonal insomnia, depression, or fatigue.

🕶️ Scientific tidbit: People living in countries with later sunsets tend to go to bed later—but still wake up at the same time. Over time, this builds up chronic sleep debt.

5. 📱 Screens Before Bed: A Global Blue-Light Problem

Smartphones have quietly become the world's most common sleep disruptor.

🇰🇷 South Korea, 🇺🇸 United States, and 🇦🇪 UAE rank among the top in daily screen time, often exceeding 6+ hours. High tech use, especially before bed, lowers melatonin and delays sleep onset.

Compare that to countries like 🇲🇽 Mexico or 🇮🇹 Italy, where evening rituals (like shared meals or family TV time) slow things down before bed—helping sleep come more easily.

💡 Sleep science: Just 30 minutes of blue light exposure at bedtime can delay melatonin release by over an hour, especially in teens and older adults.

Sleep inequality often mirrors financial inequality.

In wealthier countries like 🇺🇸 the U.S. and 🇧🇷 Brazil, sleep deprivation disproportionately affects lower-income groups. Multiple jobs, shift work, and noisy urban housing create sleep deserts—while the affluent insulate themselves with sleep aids, tech, and better environments.

Meanwhile, middle-income countries like 🇨🇱 Chile or 🇵🇱 Poland show smaller sleep gaps—less wealth, but greater parity in rest.

📈 Market signal: The sleep industry—apps, devices, supplements, coaching—is booming, with projections topping $130 billion globally by 2030.

In some places, sleep isn’t just health—it’s heritage.

🇪🇸 Spain’s traditional siesta culture still lingers in smaller towns, while in 🇦🇷 Argentina, naps often follow late-night dinners and tango-filled evenings.

🇮🇳 India integrates sleep into wellness, with Ayurveda promoting evening wind-down rituals, herbal remedies, and mindfulness. The result? Above-average sleep satisfaction despite urban challenges.

🛏️ Ancient insight: In tribal societies like the !Kung of Botswana, sleep happens in two natural phases—separated by quiet midnight hours for storytelling, sex, or stargazing. They average better rest than most urban dwellers.

Sleep is no longer just a lifestyle metric—it’s a signal of public health, economic structure, and cultural values.

Want to understand a society? Don’t just look at its income, diet, or education. Ask how its people sleep.

Because in a fast-moving, digitally saturated, economically anxious world, the real luxury may not be wealth—but rest.

Until next time, rest wisely and stay curious.
