1) I tried it, enjoyed it, thank you for building it.
2) I learned something new: I was aware of how making the exhale longer than the inhale promoted relaxation. Somehow I hadn't thought of inverting it for the opposite effect: more energy. Your app mentioned it and it was an "aha" moment for me. I tried it, and certainly feel something, but too early to say if it's a placebo effect or something real. Thank you for this new knowledge.
3) The pause portion. What does Richie Davidson (or other research say about it). What does it do, please? That is, what is the difference between not pausing at all between inhale and exhale, vs. pausing (i.e. box breathing)? Thanks in advance.
re: #3, I wish I had a clear answer for you. I believe the Navy Seals use box breathing (4 sec each for inhale, hold, exhale, hold) because it puts them in a calm, high-energy state. Those two descriptors may seem paradoxical, but it's a state I've manage to put myself in before, say, a sales call or public talk. You want high energy to raise the energy level of the audience, but you want calm to be making better decisions in a quickly changing situation.
That differs, I think, from a physiological sigh where you're just trying to relax, which the longer exhale vs inhale gets you.
James Nestor talks about the effects of breath holds in his book "Breath", and one thing he brings up is "carbon dioxide therapy"; ie exposing yourself to mildly elevated levels of carbon dioxide for brief periods was once thought to be beneficial, and he cites people claiming the research has not been disproven. One of the supposed benefits (I'm not a doctor!) is anxiety reduction, similar to how people might tell someone who is panicking to breath with a brown paper bag over their mouth.
