Slow breathing can calm nerves quickly; bottom-up regulation: body tells brain “you’re safe”.

Professional public speakers use a beta blocker like propanolol before going on stage.
also helped my chronic acid reflux/lpr but its more of diaphragmatic breathing. its backed by research.
using phones and laptops all day stuns your brain into shallow breathing all day.when i was kid i remember my dad taking naps in the afternoon and his belly moving up and down as he slept peacefully. i dont think anyone does that anymore.
i have a pet theory that this is what is driving high gastro cancers in young ppl.
It's also useful for actually speaking better; diaphragmatic breathing is necessary for projecting the voice without damaging it.
Slow breathing (in yoga: pranayama) instantly down-regulates your nervous system by boosting vagal tone and lowering sympathetic "fight-or-flight" activity. When your breath lengthens, it signals your brain that you are completely safe, dropping your heart rate and lowering blood pressure.
