Breathing exercises for anxiety, sleep, and stress relief. Svasa guides you through Box Breathing, 4-7-8 Sleep, Equal Breathing, and Custom rhythms — a calm, guided breathing app for nervous system regulation.

No streaks. No badges. No guilt-trip notifications. Just a quiet screen, a soft rhythm, and the breath your body already knows how to take.

WHAT'S INSIDE

▸ Box Breathing (4·4·4·4)
The classic deep breathing technique used by Navy SEALs, surgeons, and elite athletes for high-pressure focus. Inhale 4, hold 4, exhale 4, hold 4 — synchronizes your autonomic nervous system to restore clarity and a sense of control within minutes.

▸ 4-7-8 Sleep Breathing
Dr. Andrew Weil's signature relaxation technique for insomnia and bedtime anxiety. The long exhale activates the vagus nerve and your parasympathetic ("rest and digest") response, easing the mind into sleep in as few as four cycles.

▸ Equal Breathing (Sama Vritti)
The yogic balanced-breath pranayama practice — simple, steady, endlessly repeatable. Ideal for meditation, work focus, study sessions, or any moment that needs a quiet, grounded presence.

▸ Custom Rhythm
Design your own breathing pattern. Adjust inhale, hold, exhale, and empty-hold durations to find the cadence your body needs today. Save your favourite rhythms as named presets.

WHY BREATHWORK?

Controlled breathing is one of the few practices clinically shown to:

• Lower heart rate and blood pressure
• Reduce cortisol — the stress hormone
• Activate the vagus nerve and parasympathetic nervous system
• Improve focus, sleep quality, and emotional regulation
• Ease anxiety, panic attacks, and racing thoughts

You don't need to believe in anything. Your body already knows how — Svasa just gives you the steady rhythm to follow.

CALM-TECH BY DESIGN

Svasa is built with emotional restraint. Some things we chose not to build, on purpose:

× No streaks — a missed day is not a failure
× No badges, points, or leaderboards
× No notifications that pressure or guilt you
× No noise, no ads, no upsells

It should feel calmer than the moment you opened it.
