Samurai breathing technique Shin-Kokyu lowers cortisol and anxiety

A Japanese breathing technique called Shin-Kokyu, used by Samurai, is claimed to significantly reduce anxiety. The method involves specific breathing patterns, tongue and lip positioning to activate the vagus nerve, and pressure on the hara point, reportedly lowering cortisol by 80% in three minutes. This technique is recommended for immediate use during anxiety spikes and as a daily practice to manage stress and the body's fear response.
