Sure thing, let’s break it down like a puzzle. When you inhale slowly, you’re letting a bigger chunk of air into your lungs, which tells your body to drop the breathing rate to about 4–6 breaths per minute. That rhythm signals the vagus nerve, the body’s “relaxation switch.” The vagus nerve then nudges the parasympathetic nervous system to slow your heart rate, lower blood pressure, and reduce cortisol, the stress hormone. The end result? Your brain gets a clearer signal that things are calm, so you feel less jittery and more relaxed—like that gentle wave you mentioned. If you keep the breath steady, your body keeps the signal steady, and you’ll notice the calm settling in faster.
