Well, it’s called the 4-7-8 technique, where you inhale for 4 seconds, keep it in for 7 seconds, and exhale for 8 seconds. From what I’ve read, when you use this technique, it tells your brain(which is in fight-or-flight mode) that there’s no need to panic, and you can go into flight mode aka feel good.
