[Machine Translation] In today's hectic, sympathetic-dominated world, the focus should be on the parasympathetic nervous system for relaxation. Breathing, spine care, perspiration, yurukatsu, laughter, etc., help to regulate the parasympathetic nervous system. The autonomic nervous system is regulated by switching on and off the sympathetic and parasympathetic nerves. In fact, in today's "rushed lifestyle," with its emphasis on typing, the sympathetic nervous system remains active. Now is the time for the parasympathetic nervous system to play an important role, as we head into the open-air summer season, free from masks.

This special issue focuses on the parasympathetic nervous system, which is the key to regulating the autonomic nervous system. The feature article describes how to regulate the autonomic nervous system from the parasympathetic nervous system through five major approaches: breathing, resetting the spine, sweating, yurukatsu (relaxing activities), and laughter. Breathing" introduces deep breathing methods for different purposes, such as inducing restful sleep and improving concentration, while "skeletal conditioning" for correcting distortions in the body is introduced for morning, noon, and night scenes.
