This book, packed with the latest research on the mysteries of "dreams" and "sleep," explains their mechanisms in an easy-to-understand way, making it a captivating read for both children and adults!
Sleep is an important physiological phenomenon for us, yet there is surprisingly much we don't know about it.
Sleep is not just a period of rest; it's a time when our bodies are actively engaged in various functions such as maintenance, clearing waste from the brain, and organizing our emotions.
It is also understood that sleep is part of learning activities.
Dreams we have while sleeping always have some kind of "trigger," and we dream in relation to it.
This book is the 10th installment in the "Don't Adults Know?" series, which explains the many "I didn't know!" aspects of "dreams" and "sleep" in a way that is easy for children to understand.
Reviews from bookstore staff!
○ Haruka Miura, Miyawaki Shoten, Shin-Yashima Store
I enjoyed reading it.
There are many mysteries even for adults, but among them are dreams and sleep, which most people "don't know" about!! It's a continuous stream of "Wow!" and "Oh!".
The "Mystery Columns" subtly included on each page are also wonderful...
○ Akiko Nakano, Usagiya TSUTAYA Higashi-Yanase Store
This is a book that should be picked up now, as attention to sleep is increasing!
When we're busy, we tend to cut back on sleep, but it seems that prioritizing sleep is actually better in many ways.
There's an excitement that comes from a field that still holds many mysteries.
The column on astronaut hibernation evokes a sense of romance connected to the unknown world.
○ Yu Nakamura, Kikuya Shoten, Kokufu Store
From the very first page, there are "mysteries of sleep" that I "didn't know"!
Everyone knows that "sleep is important," but by understanding *why* it's important, this book is perfect for improving lifestyle habits related to sleep, which we tend to neglect despite knowing its importance!!
Especially the "Column for Good Sleep" on page 119...! I want to shout it from the rooftops about a hundred million times!
Let's make it a physical book! Haha
○ Rieko Shio, Kumazawa Shoten, Nishi-Arai Store
Even though I knew "sleep is important," I always had so many things I wanted to do and had to do every day that I felt "it's a waste to sleep," so I cut back on sleep. But after reading this, I now feel "it's a waste *not* to sleep early!" It covers the depth of sleep, which is not just rest and recovery, methods for getting more effective sleep benefits, and surprising trivia about animal sleep. It's a book full of wonder, surprise, and fun that you'll want to read many times.

Understanding biases (ways of thinking) might help you act without being trapped by prejudice or preconceived notions.
"Bias" is a way of thinking that everyone has.
Because of it, we might act with prejudice or in strange ways, and many people have a negative impression of the word "bias" itself.
However, biases are not always bad.
Biases can also be useful for calming the mind or making quick judgments.
Some researchers believe that "biases are ways of thinking acquired during human evolution."
This book introduces biases that tend to occur in daily life.
By recognizing biases, you may gain a different perspective and learn to live with them.
