What’s in it for me? Get inspired to become a world-class sleeper.

When people talk about how to improve their lives, the most typical goals include losing weight, being more mindful, exercising more, eating healthier or simply becoming a better person in general. But how often have you heard someone make a New Year’s resolution to get better at sleeping?

It might sound like an excuse to be lazy, but sleep is a key process for the body that influences our ability to achieve other goals. But how do you get better at sleeping?

These blinks will look at what happens to us when we sleep, and when we don’t, as well as the key factors that can improve or impair your sleep. It’s time for a bit of Night School.

In these blinks, you’ll learn

why only 15 percent of people get the amount of sleep they think they need;
how sleeping badly can even have an environmental impact; and
what the most important factors are for better sleep.

A good night’s sleep involves five stages where muscles relax, brain waves decrease and dreams begin.

Everyone knows that sleep is just what you do when you’re not awake, right? Well, while some of us might take sleep for granted and think of it as a simple daily routine, it’s actually a fascinating and complex process.

Before we fall asleep, we need to gradually help the mind and body relax.

With an electroencephalogram, or EEG, scientists can monitor brain activity and see that our brains produces between 12 and 30 electric waves per second when we’re awake. But when we settle into bed, this slows down to around 8 to 12 waves per second.

In the first stage of sleep, the muscles and the mind relax, and brain activity slows down even further, to around three to seven waves per second. This is when the brain begins to produce creative and less rational ideas.

Salvador Dalì took advantage of this stage by holding a spoon over a glass, and as he would drift off into the first stage of sleep, his muscles would relax and the spoon would fall into the glass, waking him up. He would then use the abstract images or idea that he had just imagined in his art.

In the second stage, muscles continue to relax and your breathing becomes deeper. This is the stage when your throat muscles relax and snoring can ensue.

After the second stage, we move from light sleep into the deep sleep of stages three and four.

At this point, brain activity decreases to just one or two waves per second, and the body is entirely disconnected from its surroundings, which is why it is difficult to wake someone up when they’re in the third or fourth stage of sleep. And if they do wake up from these stages, they’ll likely feel groggy and have a hard time focusing for a little while.

Finally, in stage five, the heart rate accelerates and rapid eye movement (REM) begins, which is a sign that the person is dreaming.

From here, the whole cycle starts again. Progressing from stage one to stage five generally takes about 90 minutes – so the entire process can repeat about five times in an average night.

Ever since the invention of the light bulb, we’ve been getting less and less sleep.

If you’ve ever been out camping in the wilderness or spent some time in a cabin, away from electricity, you may have noticed that the quality of your sleep improves. This is because the invention of the light bulb has completely changed our relationship with sleep.

The inventor of the light bulb, Thomas Edison, considered sleep to be a waste of time. The way he saw it, why sleep when he could be inventing gadgets in his New Jersey laboratory? The only thing stopping him from working around the clock was the difficulty of working by candlelight or oil lamps at night.

Sleep deprivation has serious consequences and losing even small amounts of sleep can cause accidents.

Everyone knows the tragic story of the Titanic, but what was the root cause of the ship striking the iceberg that led to its demise? Was it merely that the captain had the ship going too fast – or did sleep deprivation also play a role?

We may never know all the circumstances at play with the sinking of the Titanic, but we do know that sleep deprivation can have a hand in such fateful disasters.

Some people can thrive with a minimal amount of sleep, but they actually have a genetic mutation.

You may have met people who brag about how little sleep they need in order to feel bright-eyed and bushy-tailed in the morning. Some of them might just be trying to impress you, but others may well be telling the truth.

In the 1970s, sleep psychologist Ray Meddis discovered a remarkable phenomenon after he was introduced to a 70-year-old woman, known as Miss M., who claimed she only needed one hour of sleep per night.

Centuries of fighting insomnia have produced some phony remedies, but there are helpful ones as well.

If you’ve ever had trouble sleeping, you’ve probably realized that the harder you try, the less likely you’ll be to actually drift off.

For centuries, people around the world have struggled to get to sleep and, as a result, have come up with a host of different tricks and tips for catching some shuteye.

Sleepwalking is a mysterious condition that can have surprising and even dangerous results.

Have you ever opened your refrigerator in the morning and found your leftovers were gone? Or maybe there’s evidence that someone came into your kitchen and prepared an entire meal while you were asleep? Before you call the police to report a hungry burglar, you should know that there might also be a perfectly innocent explanation.

Sleepwalking is a mysterious phenomenon that almost always occurs in the deep sleep phases before rapid eye movement sets in.

There’s evidence that we can be influenced during sleep through repeated words and phrases.

If you’ve ever wished you could break an annoying habit, you might be able to do it in your sleep.

In 1942, psychologist Lawrence LeShan observed a group of boys at a New York summer camp in order to conduct a sleep experiment. He split the camp into two groups: those who bite their nails and those who didn’t. The nail-biters were then split into two groups, one being a control group that would not receive any sleep suggestion, and one that would.

Dreams can play an important role in coping with unpleasant experiences and moving on with your life.

You likely wouldn’t consider a nightmare about being trapped on an examination table and cut open by an evil doctor to be a good thing – but there’s a reason we have such graphic or terrifying dreams.

Dreams are an important way for us to process our life experiences, especially when they’re difficult or traumatic.

People have been struggling with sleep for centuries, and while we’ve come up with some methods for alleviating insomnia, we’ve also gained a lot of insight into why sleep is so crucial.

❤️ für Blinkist️️️

Ines S.

Ich bin begeistert. Ich liebe Bücher aber durch zwei kleine Kinder komme ich einfach nicht zum Lesen. Und ja, viele Bücher haben viel bla bla und die Quintessenz ist eigentlich ein Bruchteil.

Genau dafür ist Blinkist total genial! Es wird auf das Wesentliche reduziert, die Blinks sind gut verständlich, gut zusammengefasst und auch hörbar! Das ist super. 80 Euro für ein ganzes Jahr klingt viel, aber dafür unbegrenzt Zugriff auf 3000 Bücher. Und dieses Wissen und die Zeitersparnis ist unbezahlbar.

Ekaterina S.

Extrem empfehlenswert. Statt sinnlos im Facebook zu scrollen höre ich jetzt täglich zwischen 3-4 "Bücher". Bei manchen wird schnelle klar, dass der Kauf unnötig ist, da schon das wichtigste zusammen gefasst wurde..bei anderen macht es Lust doch das Buch selbständig zu lesen. Wirklich toll

Nils S.

Einer der besten, bequemsten und sinnvollsten Apps die auf ein Handy gehören. Jeden morgen 15-20 Minuten für die eigene Weiterbildung/Entwicklung oder Wissen.

Julia P.

Viele tolle Bücher, auf deren Kernaussagen reduziert- präzise und ansprechend zusammengefasst. Endlich habe ich das Gefühl, Zeit für Bücher zu finden, für die ich sonst keine Zeit habe.
