sleep

Sleep has a rhythm.
I think many people have heard this story.

Have you ever been woken up by a fall asleep and didn't notice it at all?
I have lived for many years 24 hours a day, 7 days a week, with contact from the hospital.
Even if I called in the middle of the night, I was answering immediately,
I once didn't realize that the phone rang.
It was about 30 minutes - 1 hour when I fell asleep.

I woke up because I was called about 10 times.
Why?? When I fell asleep and saw the phone, it was a missed call.



At the beginning of sleep, you go into a deep sleep.
After that, it became shallow little by little, rem sleep, it is time to dream.
Then repeat the cycle of going deeper again.

This first cycle is about 90 minutes, and before it gets shorter and shorter, it takes about 60 minutes.

People who wake up many times in the middle of the night and go to the bathroom
It seems that it is often woken up in this cycle roughly.

There are quite a few cases where you wake up because your body hurts when you turn over.

This cyclical rhythm.
With age, you may not be able to sleep deeply.

I hear quite a few stories that I don't feel like I've slept at all because I'm just dreaming.
This is also because sleep is shallow.

I talked about melatonin in the last blog
The quality of light and sleep is related.

Soak up the light firmly during the day and move your body in moderation.
Before going to bed at night, spend a little dimly.

You have to be ready to go to bed.
There are actually many people who are getting up forcibly even though their bodies are already ready to sleep.
There may be many people who fall asleep the moment they turn off the TV.

When I was young, I could sleep soundly until morning.
Recently I've been lying down, I wake up in the middle of the night,
wake up early in the morning

Isn't that true?

Have you ever heard of melatonin?

It is a necessary hormone for sleep.
This melatonin is a famous happy hormone that can be from serotonin.
Serotonin is made from the essential amino acid tryptophan.

Melatonin is a hormone secreted at night.
And this hormone secretion peaks at the age of four and continues to decrease.
Therefore, there are a lot of people who the quality of sleep becomes bad with age.


Melatonin is light that suppresses secretion.
So if you watch a smartphone or watch TV before going to bed at night,
The secretion of melatonin is reduced.

To improve sleep quality by focusing on melatonin
And do not watch TV or smartphone before going to bed at night,
It will make the intestinal environment in good condition.


However, the secretion of melatonin decreases with age.

You also need to pay attention to your diet in order to replenish melatonin.
In order to effectively replenish melatonin, it is necessary to have something that contains a lot of melatonin sources in the body.
It's quick to take in, isn't it?
It's also good to have something safe.

There are a variety of ingredients.　Be sure to check it out.

Is it really so?
Sleep doesn't just rest your body.
It also organizes memories.

When I entered university, I felt that there were many people who were shorter than when I was in high school.
