Reading Time: <1 minute Recently, there has been a lot of media coverage of breathing techniques. This is a book I published previously. It was co-authored with Professor Hiroyuki Kobayashi of Juntendo University School of Medicine. There are many books on breathing techniques, but unfortunately none of them seem to capture the essence of breathing techniques. Breathing techniques can also be considered heart rate variability biofeedback training, which is a method to improve autonomic nervous function. There have been very few books published so far that explain why breathing techniques are good for your health from an autonomic nervous system approach. This is probably the first book in Japan to add a medical approach, written by us, the first researchers of the autonomic nervous system in Japan. Breathing techniques are also attracting attention as a main theme in Demon Slayer. You can understand the mechanism and true meaning of breathing techniques in this book.
