What the research actually shows about settling, surfacing and the space between — with its limits stated.
A double inhale followed by a long exhale — the most evidence-backed breathing technique in circulation, and also widely oversold. The trial everyone cites tested five minutes a day for a month, not one sigh in a bad moment.
Usually one of three reasons: you may not be wound up in the first place, you may be breathing bigger rather than slower, or you may be running into relaxation-induced anxiety — a documented paradox with forty years of research behind it.
