Box: 16s per breath (4+4+4+4), 4-7-8: 19s, Coherent: 10s; Breaths = minutes*60 / breathTime

How does this work?

Box breathing is 4s inhale, 4 hold, 4 exhale, 4 hold (16s). 4-7-8 is inhale 4, hold 7, exhale 8 (19s). Coherent is 5 in, 5 out (10s) at 6 breaths/min for HRV.

These are wellness for stress, not medical treatment for panic or hyperventilation — seek care if needed.
