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

: slowly builds the desire for sleep throughout the day Melatonin : produces drowsy feelings that signal your body is now ready for sleep

: 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.

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. 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. 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. 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. 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. 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.
