Visualizing the World's Sleeping Habits

Visualizing the World’s Sleeping Habits

Sleep quality, patterns, and duration may vary among countries, but one thing’s clear─people still aren’t getting enough sleep. While some people can function on a few hours, others find themselves reaching for that second cup of morning coffee instead of getting those extra Z’s.

Today’s graphic comes from Raconteur and highlights some startling takeaways from the 2019 Philips Global Sleep Survey, answered by over 11,000 adults from 12 countries.

Let’s settle in to discover what impacts our sleeping habits, also known as sleep hygiene, and what helps people sleep better and longer.

Why Sleep Is Important

Roughly 62% of adults worldwide feel that they don’t sleep well when they go to bed. Losing just one or two hours of sleep per night can have the same impact on motor and cognitive functions as going without sleep for a full day or two.

Experts have long emphasized that developing good sleeping habits can help to maintain our physical, mental, and emotional well-being. Ongoing sleep deprivation can also cause severe, long-term health conditions:

  • Heart disease and heart failure
  • Weak immune system
  • High blood pressure
  • Kidney disease
  • Depression
  • Diabetes
  • Obesity

Drowsiness has been a significant factor in roughly 100,000 car accidents every year, causing an estimated 1,500 deaths. Sleep deficiency has also been linked to a number of disasters, such as airplane and boat accidents, and even nuclear reactor meltdowns.

The Science of Sleep

The human body follows the circadian rhythm─a 24-hour repeating rhythm that operates as an internal clock. This clock is controlled by two things: external cues such as light and darkness, and internal compounds that trigger and maintain our sleep.

These chemicals work together to keep our sleep/wake cycles in harmony.

  • Adenosine: slowly builds the desire for sleep throughout the day
  • Melatonin: produces drowsy feelings that signal your body is now ready for sleep
  • Cortisol: naturally triggers your body to wake up

While sleep duration can vary greatly around the world, most adults are still not getting enough shut-eye. The average person gets 6.8 hours of sleep on a weeknight, which is significantly lower than the recommended 8 hours.

One company in the UK has even developed a real-time map of social media posts from people who say they can’t fall or stay asleep.

What Prevents Better Sleep?

People can suffer from a lack of sleep for many reasons─below are the top six culprits.

  1. Worry and Stress
    Job, family, health, financial, and a myriad of other concerns plague people from all walks of life. Adults living in Canada and Singapore tend to be the most worried.
  2. Environment
    The physical space where you sleep plays a large role in the quality and duration of your sleep. Nearly 35% of adults fall asleep somewhere other than their bed. Interestingly, Chinese adults are the least comfortable when sleeping, while Japanese adults are the most comfortable.
  3. Work and School Schedules
    Hectic careers and heavy school workloads have a direct and lasting impact on sleeping habits. Many forego sleep in favor of completing work, social, and household responsibilities.
  4. Entertainment
    In the age of technology, natural rhythms of daytime and nighttime perception have been skewed, especially from the effects of blue light emitted from our device screens.
  5. Disruptors
    Eating food, or drinking alcohol or caffeine within the last few hours before bedtime can prevent our brains from knowing it’s time to wind down and get ready for sleep. Adults living in the fast-paced developed nations of China, Canada, the United States, and Singapore are the most caffeinated.
  6. Health Conditions
    Over three-quarters of adults experience at least one health condition that impacts sleep. These include insomnia, sleep apnea─which affects roughly 22 million people in the U.S. alone─snoring, restless leg syndrome (RLS), narcolepsy, and chronic pain.

Developing Good Sleeping Habits

Sleep is often the first to be neglected with our hectic schedules. Here are a few ways to practice better habits for a good night’s sleep.

Routine
Wake up and go to bed at the same time each day─even on weekends─to establish a more ingrained rhythm for your body clock and help your brain better prepare for sleep.

Exercise
Pick a time of day that suits your schedule and energy levels, and be sure to stick with it. Exercise helps to balance melatonin and cortisol levels throughout the day.

Light
Get outside often during the day and reduce the time spent outside at night. Limit screen time at least 30-60 minutes before sleep.

Food and Drink
Avoid eating large meals or drinking alcohol or caffeine in the last couple of hours before you go to sleep. Caffeine effects can linger for up to 8 hours, which breaks natural sleep rhythms.

Meditation
Recent studies have shown that mind-body treatments for insomnia such as yoga, tai chi, and meditation had positive impacts on improving sleep quality.

Comfort
Set the bed for success—keep your room cool and dark, buy a high-quality mattress and comfortable bed linens and use a white-noise machine to help you fall asleep.

Sleep is one of the most important aspects of our health; it’s also one of the easiest to neglect. Don’t put yourself into sleep debt─get enough shut-eye to enjoy those sweet dreams.

Watching the Sky Fall: Visualizing a Century of Meteorites

This data visualization depicts every meteorite that was observed hitting the Earth over a 100-year period, between 1913-2012.

Watching the Sky Fall: Visualizing a Century of Meteorites

Astrophysicist Neil DeGrasse Tyson once said “The chances that your tombstone will read ‘Killed by an Asteroid’ are about the same as they’d be for ‘Killed in Airplane Crash’.”

Part of the reason for this is the Earth’s atmospheric ability to burn up inbound space rocks before they reach the surface, a process that ensures that most meteors never become meteorites.

Of the 33,162 meteorites found in the past 100 years, only 625 were seen. Today’s visualization from data designer Tiffany Farrant-Gonzalez groups these 625 observed meteorites by the year they fell, classification, mass, and landing location on Earth.

Asteroid, Meteoroids, Meteors, and Meteorites

Not all flying space rocks are the same. Their origins and trajectories define its type.

Asteroid: A large rocky body in space, in orbit around the Sun.
Meteoroid: Much smaller rocks or particles in orbit around the Sun.
Meteor: If a meteoroid enters the Earth’s atmosphere and vaporizes, it becomes a meteor, or a shooting star.
Meteorite: If a small asteroid or large meteoroid survives its fiery passage through the Earth’s atmosphere and lands on Earth’s surface.
Bolide: A very bright meteor that often explodes in the atmosphere, also known as a fireball.

Classification

This graphic classifies meteorites into four types based on their composition: stony, stony-iron, iron and other.

StonyStony-IronIronOther
Achondites
Chrondites
Unclassifed
Mesoiderites
Pallasites
Magmatic
Non-magmatic or Primitive
Doubtful Meteorites
Pseudometeorite

Top 5 Meteorites by Size

While half of all observed meteorites weighed less than 2.5 kg (5.5 lbs), there are a few exceptional ones that stand out. The graphic highlights the five largest meteorites ever observed, and when they fell:

LocatonSizeYearType
Sikhote-Alin, Russia23 MT1947Iron
Jilin, China4 MT1976Stony
Allende, Mexico2 MT1969Stony
Norton County, USA1.1 MT1948Stony
Kunya-Urgench, Turkmenistan1.1 MT1998Stony

Each category differs in their amount of iron-nickel metal and what they reveal about the early solar system.

Fireballs in the Sky: Bolides

Small asteroids frequently enter and disintegrate in Earth’s atmosphere randomly around the globe, creating fireballs known as bolides. NASA’s Near-Earth Object Program mapped data gathered by U.S. government sensors from 1994 to 2013.

Source: NASA

The data indicates that small asteroids impacted Earth’s atmosphere, resulting in a bolide (or fireball), on 556 separate occasions over a 20-year period. Almost all asteroids of this size disintegrate in the atmosphere and are harmless.

A notable exception was the Chelyabinsk event in 2013, which was the largest known natural object to have entered Earth’s atmosphere since the 1908 Tunguska event. A house-sized asteroid entered the atmosphere over Chelyabinsk at over 11 miles per second, and blew apart 14 miles above the ground.

The explosion released an energy equivalent to ~440,000 tons of TNT, generating a shock wave that shattered windows over 200 square miles—damaging several buildings and injuring over 1,600 people.

Look Out Above

While the night sky appears to be a beautiful tableau of the cosmos, these two visualizations paint a dramatic galactic battle. Rocks inundate our planet as it moves through the darkness of space. The resiliency of Earth’s atmosphere to erode these invaders has allowed life to flourish⁠—until the next big one comes through.

Remember the Dinosaurs?

Mapped: Top Countries by Tourist Spending

How much do your vacations contribute to your destination of choice? This visualization shows the countries that receive the most tourist spending.

Mapped: Top Countries by Tourist Spending

Many people spend their days looking forward to their next getaway. But do you know exactly how much these vacation plans contribute economically to your chosen destination?

Today’s visualization from HowMuch.net highlights the countries in which tourists spend the most money. Locations have been resized based on spending amounts, which come from the latest data from the World Tourism Organization (UNWTO).

Oh, The Places Tourists Will Go

Across the different regions, Europe’s combined tourist spending dominates at $570 billion. Easy access to closely-located countries, both via rail networks and a shared currency, may be a reason why almost 710 million visitors toured the region in 2018.

Asia-Pacific, which includes Australia and numerous smaller islands, saw the greatest growth in tourism expenditures. Total spending reached $435 billion in 2018—a 7% year-over-year increase, from 348 million visitors. Not surprisingly, some areas such as Macao (SAR) tend to rely heavily on tourists as a primary economic driver.

Here’s how other continental regions fared, in terms of tourist spending and visitors:

  • Americas
    Total expenditures: $333 billion
    Total visitors: 216 million
    Expenses per visitor: $1,542
  • Middle East
    Total expenditures: $73 billion
    Total visitors: 60 million
    Expenses per visitor: $1,216
  • Africa
    Total expenditures: $38 billion
    Total visitors: 67 million
    Expenses per visitor: $567

Of course, these numbers only paint a rudimentary picture of global tourism, as they vary greatly even within these regions. Let’s look closer at the individual country data for 2018, compared to previous years.

The Top Tourist Hotspots, By Country

It seems that many tourists are gravitating towards the same destinations, as evidenced by both the number of arrivals and overall expenditures for 2017 and 2018 alike.

Note that data is for international tourism only and does not include domestic tourism.

The top contenders have remained fairly consistent, as each country brings something unique to the table—from natural wonders to historic and man-made structures.

Where Highest-Spending Tourists Come From

The nationality of tourists also seems to be a factor in these total expenditures. Chinese tourists spent $277 billion internationally in 2018, likely thanks to the increasing consumption of an emerging, affluent middle class.

Interestingly, this amount is almost twice the combined $144 billion that American tourists spent overseas in the same year.
