Coherent Breathing Timer

About this coherent breathing timer

Coherent breathing — sometimes called resonant breathing — is breathing at roughly 6 breaths per minute, or 5 seconds in and 5 seconds out. At this rate, heart rate variability and blood pressure oscillations synchronize, which research suggests strengthens autonomic flexibility and stress resilience.

It's the simplest breathing technique available: no holds, equal in and out, no special posture required. The trade-off for that simplicity is that it requires sustained practice — the benefits accrue from regular sessions over weeks, not from a single dramatic experience.

How to use this timer

1. Sit upright or lie down. Hands on belly to feel the breath if it helps.
2. Press Start. Inhale gently for 5 seconds, exhale for 5 seconds. No holds.
3. Breathe through the nose if comfortable. The breath should feel slightly slower and deeper than usual but never strained.
4. For the first few sessions, the 5-second pace may feel slow. Stick with it — the benefits of resonance frequency breathing only show up at this rate.

When to use it

• As a daily practice: 5–20 minutes a day, ideally at the same time. The benefits compound over weeks.
• Before sleep: simpler than 4-7-8 and easier to sustain when tired.
• For HRV training: athletes and biofeedback users practice at this pace specifically to improve heart-rate variability.
• During mild stress: easier to remember than complex patterns when the mind is busy.

Compared to other breathing techniques

• Box breathing (4-4-4-4): adds holds — more structured, useful for acute focus.
• 4-7-8 breathing: emphasizes the exhale — stronger relaxation, harder to sustain for long sessions.
• Coherent breathing (5-5): the everyday workhorse. Built for sustained daily practice rather than acute use.

Tips

• Don't aim for deep breaths. Slow and even is the goal, not big and dramatic.
• If 5 seconds is too long, start at 4-4 and work up. The resonance frequency varies by individual — somewhere between 4.5 and 6.5 seconds per phase is optimal for most adults.
• Longer sessions matter more than perfect technique. A 20-minute slightly imperfect session beats a 2-minute perfect one.
