WHY BREATHING EXERCISES WORK
Breathwork activates your parasympathetic nervous system — the "rest and digest" response that counters stress and anxiety. Even 2-5 minutes of guided 4-7-8 breathing or box breathing can measurably lower heart rate, reduce cortisol, and improve focus. That's why Navy SEALs use box breathing, and why Stanford researchers recommend the physiological sigh.

The science behind breathing exercises is well established. Slow, controlled breathing through techniques like box breathing and 4-7-8 breathing directly influences your autonomic nervous system. By extending the exhale and adding breath holds, you stimulate the vagus nerve, which triggers a relaxation response throughout the body. Regular practice builds resilience to stress over time — not just in the moment.

HOW TO GET STARTED
Open the app and choose a breathing pattern. The animated guide expands and contracts to lead your breath — inhale as it grows, hold when it pauses, exhale as it shrinks. You set the session length. A gentle vibration marks each phase transition so you can close your eyes and stay fully present. After your session, log your mood and any notes. Your streak updates automatically.

If you're new to breathwork, start with box breathing (4-4-4-4): four counts in, four hold, four out, four hold. It's symmetrical, easy to learn, and immediately calming. Once it feels natural, try 4-7-8 breathing for sleep — its longer exhale is especially effective at slowing a racing mind at bedtime.

CUSTOM PATTERNS
Not every person responds the same way to every breathing ratio. This breathing timer lets you set your own inhale, hold, and exhale counts so you can dial in the rhythm that works best for you. Save it and come back to it anytime.

Breathing Timer works offline and is designed for fast daily use. Whether you're new to box breathing or a seasoned breathwork practitioner, this breathing timer guides you through every phase.
