💭 Why doesn't a person remember the moment of falling asleep?

The point is that this moment is not recorded by the brain due to switching off the long-term memory (and switching on the short-term memory).

☝🏻 It has been proven that a person does not remember what happens 5 minutes before the moment of dreaming. For example, if you wake up a sleeping person and ask him something, and then he falls asleep in less than 5 minutes, he will remember nothing of the conversation upon awakening.

🍎 Why is an apple better for waking up than coffee?

Many people start their day with a cup of coffee, which has a reputation as an invigorating drink that helps them wake up and get in the mood for work. But the reality is that an apple is a much better way to wake up in the morning, perk up and get into a rhythm at work.

It contains fructose, carbohydrates and fiber, which are converted into energy by entering the body. Thus, they literally wake up every cell of the body and make it work.

☝🏻 The sugar that people put in coffee is much less effective than fructose.

☑️ A natural sleeping pill

☝🏻 Melatonin is the body's natural sleeping pill. Melatonin is a hormone of the epiphysis that regulates the circadian rhythms of the body. The function of melatonin is as follows: during the day we feel energized, active and alert, while in the evening we feel tired and sleepy.

This hormone also protects us from stress and premature aging, from colds and cancer. It is one of the strongest natural immunomodulators and antioxidants.

💫 Melatonin is formed from the amino acid tryptophan, so you can increase the synthesis of melatonin by eating foods that contain tryptophan. These include: potatoes, corn and dark chocolate.

🧠 Our brain is capable of reading 1,000 words per minute

There are three types of reading. The first is reading to ourselves, when we mentally say the words. The second is reading aloud, and the third is so-called visual reading, when the text is perceived without saying the words at all.

◽️We read silently at the slowest rate of 250 words per minute. Out loud, we read 450 words per minute. Visual reading, on the other hand, allows us to read 700 words per minute!

◽️Moreover, our brain can perceive the information being read at a rate of 1,000 words per minute, and if we practice, we can reach this incredible rate.

💤 Why don't people sneeze in their sleep?

How does it happen when we are awake:

ℹ️ When something abruptly irritates our nose, nerve endings send impulses to the brain.

ℹ️ It shifts responsibility for what's happening to the pectoral muscles, then the lungs fill with air.

ℹ️ The openings leading from the pharynx to the mouth close, preventing air from the lungs to the mouth.

ℹ️ Then a sudden, violent exhalation occurs, and the person sneezes.

❗️So, during sleep, the nervous system is resting. Therefore, there is no one to give the command to sneeze.

Did you know, when you can't sleep on your first night in a new place, your brain is trying to protect you. Many animals sleep with only half their brain, while the other half stays alert to possible dangers. It's called the 'first night effect' in humans, because our bodies put us in strange, half-asleep/half-awake state the first time we sleep in unfamiliar environment.

It's Impossible to Hum While You Hold Your Nose 🙄

For the same reason, you can't exhale while holding your nose and closing your mouth—to make the humming noise you have to pass air through your larynx.

You can't do that when no air can be exhaled. Still, seems pretty weird.
