[My Work] Is 'sleeping in on days off' counterproductive? What is the optimal sleep duration? [HR Work / Health]

Sleep is full of mysteries and there is much we do not understand, but researchers are clarifying those 'unknown parts,' and some of the mysteries have been solved.

I read that news.

--

As I have written in my articles before, because I repeatedly had to be hospitalized for surgeries when I was a student, I have thought about and practiced health more deeply than others.

And what my attending physicians and others strongly emphasized to me were"sleep"and"diet".

Since 'lack of sleep' and 'poor eating habits' are issues directly linked to health, I am still always careful about them.

More and more people are becoming concerned about both of these, and regarding sleep, I think it is very good that a trend is spreading where people think about routines for sleeping, and do not consider it a waste to spend money on equipment such as"pillows"and"mattresses", which I also use.

This news was a summary of such information about sleep.

As a common belief about sleep from a little while ago, many people know that "the cycle of REM sleep and non-REM sleep is 90 minutes, so sleep in multiples of 90 minutes is good."

However, rather than blindly believing that,

it is certain that since this cycle (naturally) differs from person to person, you need to find the sleep duration that suits you.

is correct.

Also, when you have errands or other commitments and are in a situation whereyou must wake up by a certain time, I thinkmany people set an alarm clock.

However, for many people, such alarms are not effective.

I am the same way, but once in a while, I"unconsciously turn off the alarm and go back to sleep"...

In such cases,

It is said that there is a paper stating, "If you go to sleep with the intention of 'waking up at XX o'clock!', you can wake up in the morning."

Indeed.

Certainly, there are times when you wake up before the alarm goes off, aren't there?

One of the reasons why research on sleep has progressed as mentioned above is because of the massive amount of data from the sleep game app "Pokémon Sleep," which became a big hit a while ago and is still loved by many.

That is what has become clear.

It means that.

Everyone enjoys sleep,

and researchers advance their studies with the data obtained from it.

I think it is a very win-win relationship.

How to find your optimal sleep duration

The following steps are what you should take to find your own optimal sleep duration.

If there is variation in your sleep duration, you need to do the same on the fourth day.

As mentioned above, a situation where you can get comfortable sleep (= a situation where you can get relaxed sleep) is rarely found in daily life.

Therefore, it is best to do this during long holidays when you are off from work.

One-third of life is sleep

is what they say, and

there is no doubt that high-quality sleep leads to 'academics' and 'work',

so it is necessary to invest your own money, time, and effort to get the sleep that suits you.
