A daily routine of several pranayama techniques (box breathing, bhramari, alternate-nostril breathing...) to defuse stress is a reasonable way to turn slow breathing into a habit — what matters is the steady slowness, not the exact list of named techniques.

The core claim — that these techniques 'reduce cortisol levels' — has real experimental backing: a randomized pilot trial (Frontiers, 2017, n=40, 8 weeks) found a measurable drop in salivary cortisol in a diaphragmatic-breathing-trained group versus controls, and a 2024 study following a standardized Trier Social Stress Test found a similar single-session effect. These trials are still small (40-44 people) and study diaphragmatic/slow breathing generally, not this exact combination (kapalbhati + box + alternate nostril + bhramari) — so 'proven' overstates it a bit; 'well supported' is more honest. The rest (mental clarity, balance) is plausible felt experience rather than a named, measured result. Verdict: mixed, leaning positive — cortisol reduction from slow breathing is one of the field's better-replicated findings, but this exact routine hasn't been tested as a package.
