Coherent (resonance) breathing at about 5.5 breaths a minute

Coherent breathing - also called resonance breathing - means slowing your breath to about five to six breaths a minute, often around 5.5 seconds in and 5.5 seconds out. This slow, even pace is the one most studied for increasing heart-rate variability.

The pace matters more than perfection: anywhere near six breaths a minute, with no holds, is the idea. It suits almost everyone.

The rhythm

Rhythm: 5.5 · 5.5 (one cycle ≈ 11s)

Breathing phases in seconds
Phase	Seconds
Inhale	5.5s
Exhale	5.5s

About 5.5 in and 5.5 out - roughly 5 to 6 breaths a minute. Some people find their personal "resonance" pace slightly faster or slower.

How to do it

Slow to about six breaths a minute
Roughly 5-6 seconds in and the same out.
Keep it even and unforced
No holds; let the breath be smooth.
Continue for several minutes
The effect builds with a little time.

Common uses

A calm, steady baseline practice.
HRV-oriented breathing.
A gentle everyday reset.

What the evidence suggests

Evidence: Moderate support

Breathing near the "resonance frequency" of about six breaths a minute is associated with the largest increases in heart-rate variability, and controlled studies report improvements in HRV and mood. Individual resonance frequencies vary.^[1]^[2]

Safety

A gentle, hold-free technique that suits most people.

Beginner version

If 5.5 feels slow, start around 5 in and 5 out and ease toward a slower pace.
