Recently, you've probably seen a lot of books about sleep.
Indeed, when I look around, I see colleagues who always look sleepy, people who sway on the morning train with their eyes closed, and people who run out to buy coffee in the evening muttering, "I've had enough..."
Without exception, I'm sure there are many people who have some kind of "sleep problem" and want to improve it.

In fact, I was a part of that group until recently.
"I still feel tired even though I slept, and I get sleepy at odd times during the day.
At night, I become energetic and find myself tapping on my smartphone, a typical example of sleep deprivation.

But one day, I suddenly thought.
"Who teaches you how to sleep anyway?"

I learned Japanese and math at school, I learned how to cook from videos, and I learned my job from my seniors, but
Before I knew it, I had started to do things my own way when it came to sleep.
Unlike when I was younger and could fall asleep as soon as I got into bed, there are more and more days when I have trouble falling asleep...

So I started reading some books on sleep,
I realized that my sleep habits were full of mistakes, and I started to change them little by little every day.

This time, based on that experience,
"A book I can wholeheartedly recommend to anyone who wants to study sleep."
We would like to introduce you to the following.

■ For those who want to have a "sleep map" first

The "Super Basics of Sleep" that you can't ask about now

If you want to study sleep, it's best to start with a book that gives you an overview of the whole picture.
"The Very Basics of Sleep," supervised by Masashi Yanagisawa, is a book that is truly like a textbook in that sense.

This book covers the mysteries of sleep, the true nature of sleep debt, creating an environment conducive to sleep,
It even covers the topic of "Why do people sleep?"

As I read,
"Oh, I've been misunderstanding this until now..." I often find myself holding my head in my hands
I don't feel bad about it, but rather
I feel a strange sense of elation, thinking , "From today onwards, I'll be able to sleep a little smarter."

This is the perfect book to start learning about sleep.

■ A "savior book" for people who can't get rid of fatigue even after sleeping

Seiji Nishino, "The Stanford Method for the Best Sleep"

This is truly a classic among books on sleep.
Seiji Nishino is a leading researcher who has conducted research at the Stanford University Sleep Research Institute for many years.

When you read this book,
"I have trouble falling asleep," "I can't wake up in the morning," "I'm still tired even after sleeping," etc.
The causes of common sleep problems will become surprisingly clear.

What is particularly impressive is
It is said that the first 90 minutes of deep sleep determine the quality of your day .

If you think you may have sleep debt, I recommend you try this book first!

■ Don't underestimate the power of a nap

Takuro Endo "The Ultimate Nap Method - Super Power Nap"

In Japan, when we think of napping, we tend to think, "Sleeping at work?"
The more I learn about the research, the more I feel that napping is an essential skill for modern people.

This book is packed with everything from the science of napping to practical techniques.

What's particularly interesting is that
On the contrary, coffee before a nap can actually help you wake up better .

I was skeptical at first, but when I tried it, I found that it really did help me wake up quickly.
This book will completely change the way you look at naps.

■ You're too busy to sleep...

Yohei Sugawara "The Laws of Sleep 2.0 that Will Change Your Life"

I would recommend this to busy people!
The author, who has been teaching sleep improvement in the medical field,
He carefully teaches us "ways to improve even if you don't get enough sleep."

There are many ideas that you can start using tomorrow.
This content will be especially helpful for people who cannot find time to sleep.

■ For those who want to improve their work performance

Ryo Kakutani's "A Map for Good Sleep for Working People"

Your work productivity is directly linked to the quality of your sleep.
However, in the business world, the saying "get through it with determination" still remains...

This book lightly overturns such old values.

The content focuses on the real sleep problems faced by working people.
It is packed with many “good sleep skills that can be used in the workplace.”

■ How will reading a sleep book change your life?

The first thing that changes when you learn about sleep is
"Learn how to manage your physical condition."

The feeling of "I feel tired somehow" disappears,
"This is caffeine," "This is using my smartphone before bed," "This will be cured by taking a nap,"
The causes and solutions become apparent...

the result,

• Reduces morning fatigue
• Improved concentration
• Work progresses smoothly
• Become less irritable
• No more wasting time at night

It creates a smoothness that is almost like "adding oil to your life."

■ Finally: Studying sleep can be life-changing

All of the books I introduced today convey the author's passion.
If you're having any trouble with your sleep right now, I recommend you read at least one book!

When your night changes, your morning changes.
And every day is different.
