What’s in it for me? Understand your 24-hour mind.

Have you ever wondered what actually goes on in your mind while you sleep? Or what those bizarre images in your dreams might mean? Were you ever so curious to figure that out that you found yourself looking through old college textbooks on Jung and Freud?

The Twenty-four Hour Mind explores these questions and more, shedding light on the many activities the brain carries out while we sleep. As it turns out, sleep is a very active time. In fact, our mind is active constantly during the alternating states of waking and sleep. What’s more, the waking and sleeping mind are intimately bound in their functions – so much so that your health and even life can depend on their cooperation.

In these blinks, you’ll learn

why not getting enough sleep can make you fat,
how your dreams can actually alter your personal identity,
why you feel so cranky after a bad night’s sleep and
why getting a good night’s rest should be one of your top priorities.

Sleep helps us stay physically and mentally balanced.

We’ve all experienced the effects of a bad night’s sleep: we’re tired, can’t concentrate and are generally unpleasant to be around. But why?

There’s nothing puzzling about it: science can explain why a sleep deficit affects our body and mood.

For starters, deep sleep is an important part of the way we release tension. Our sleep is divided into two states that work together in a cycle, quiet sleep (NREM) and deep active sleep (REM), which both need to run through their cycles before waking in order to replenish the body and brain, a process which takes seven to nine hours.

Light sleepers – those who are REM-deprived – and people who don’t sleep enough are prone to be more tense than people who get enough deep sleep. For example, employees who work the nightshift and sleep during the day don’t sleep as deeply, and as a result show more signs of stress.

In addition, sleep reduces our negative emotions. One study showed that, of the 31 participants who were struggling through a divorce, 20 worked through their emotions in their sleep. In their dreams, they dealt with their anger and sadness, playing through scenes with their ex-spouses and slowly improving their “dream reactions,” helping them to develop strategies to move on.

We take strong, unresolved emotions with us into our sleep, where our minds continue to work through them and help us to come to terms with them. For example, when we get upset by a nasty comment someone makes about our looks or weight, those emotions feel less powerful after a proper night’s sleep.

Finally, our endocrine system functions best when we get enough sleep because it affects the hormones that control our appetite. In fact, most people who sleep fewer than six hours a night will experience an increase in appetite, and studies have even shown that you’re 7.5 times more likely to be obese if you’re a short sleeper.

Dreams store our experiences and help us deal with emotional problems.

Many people consider their dreams mystical – they scrutinize them looking for patterns, prophecies or some deeper meaning. In reality, dreams are simply a way to help deal with our everyday lives.

When we dream, we’re evaluating the experiences we’ve had throughout the day, linking them to similar, older experiences and filtering out new, important information that should be stored in our memory. This information is then matched with an emotional experience from the past, thus creating a dream image, which represents memories in relation to this new information.

The waking and sleeping minds process different information, interacting to guide our behavior and keep it flexible.

By this point in your life, you’ve probably realized that your experiences in dreaming and waking life are radically different. But why? It all comes down to the fundamental differences in how we process information when we’re asleep or awake.

When we’re awake, our minds receive signals from and respond to the external world almost automatically. In fact, we run largely on autopilot: once we’ve developed the behaviors that take us through the day, our perspectives, attitudes and habits – things we’d often ascribe to our personal identity – are produced without almost any conscious input.

A malfunctioning waking-sleeping cycle can lead to severe emotional disorders.

So far, we’ve learned a great deal about the importance of sleep for our waking life. But what happens if our sleeping and waking minds don’t work together as they should?

For starters, if you have difficulties sleeping, it might be a sign that you’re suffering from the beginning stages of depression. In fact, studies show that depression always starts with a malfunctioning sleep cycle, which results in crankiness and irritation. Depressed individuals stay in a sort of REM mode even while they’re awake – in other words, they aren’t able to leave the emotional state of their nighttime mind.

Too little sleep is not a minor problem: it leads to many of our world’s dominant health problems.

Often, things like poor nutrition or a lack of physical exercise are blamed for many modern-world health problems. But this comes at the cost of overlooking one of the main causes of poor health: bad sleep.

The greatest risk of not getting enough sleep is obesity, which has reached epidemic proportions in the Western world. This was demonstrated in one study in which participants were allowed only a few hours of sleep per night: the decrease in sleep caused an increase in appetite due to malfunctioning hormone regulation, and resulted in weight gain within only a week!

❤️ für Blinkist️️️

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.

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.

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.
