The science of sleep

  The science of sleep

A cobbler was making shoes. I was just cutting the leather when I fell asleep. When I woke up in the morning, the shoes were sewn. It's a magical childhood story, but it's not a lie. Sleep does something similar to us.

If you are 50 years old, you have spent 18 of those years sleeping. But these eighteen years were not a waste of time. For the brain, sleep is a global event when the entire brain changes its state. A look at what happens in the mind during this time.

 Brainwashing. Brain cells shrink slightly and rapidly, cerebrospinal fluid is pumped between the brain and nervous system to flush out toxins. When we wake up, the brain cells are enlarged again and the flow of this fluid between them stops. Dr. Nedergaard, the neurosurgeon who researched it, says the process is as dramatic as washing dishes and as a faucet turns on and off. The brain cannot do this while awake because this process requires energy and it would probably be difficult for it to simultaneously wash and analyze the sounds and sights around it, talk and move. It clears beta-amyloid. If these substances are not clean, they form a yellow layer on the brain

 Information processing and memory consolidation. The brain processes information in different ways. Experiments conducted on it show that during sleep our memory is also improved, the ability to see something from a new angle. At that time, the logical part of the brain shuts down, and this is the reason why in a dream you can do things that seem illogical when you are awake, but this is the way our mind makes sense of the world.

Tissue repair. The third stage of sleep, which is the deepest sleep, is where growth hormone is released. This is important for making fresh cells to replace dead cells

: play an important role in regulating metabolism and appetite. If the sleep is not good, then, apart from the metabolism, the signal of the brain that tells that the stomach is full is also affected.

Energy recovery. The brain's energy is glycogen, which is stored in different parts of the brain, which is depleting. It is restored during sleep and especially during the rapid eye movement stage.

 Who needs how much sleep and when? There is no one good answer, our own cycle of the darkness hormone melatonin is as unique to each person as fingerprints, but some signs

1. If you sleep more than you normally do on a holiday, you're not getting enough sleep

2. If you have to set an alarm to get up, you're not getting enough sleep

3. If you need tea or coffee to wake up in the morning, this is a sign of lack of sleep.

And if you're not getting enough sleep, this habit will make you sick, depressed, fat and stupid.

Note: If this post was so boring that you fell asleep while reading it, then this is a good post for you. If it's time to sleep, put your mobile or computer aside and go to sleep instead of doing anything else. After the rest of the matter arose.
