Resonance breathing—sometimes called coherent breathing—targets about 0.1 Hz, roughly one full cycle every ten seconds. In practice that means five seconds in and five seconds out without pauses, or four in and six out if that feels smoother.
At this pace, breathing and heart rhythms may fall into a steady rhythm that researchers sometimes link to heart-rate variability (HRV). HRV is one marker of how flexibly your body shifts between alertness and recovery—your personal trend over time matters more than any single reading. This page does not claim to normalise blood pressure or treat cardiovascular conditions.
Use a soft inhale and a gentle exhale, not a forced balloon blow. Volume should be moderate; you are pacing, not hyperventilating.
If five seconds strains, try four in and six out while keeping the ten-second total. Consistency of the full cycle matters more than perfect symmetry.
Slow equal breathing reduces sensory noise. When the body stops signaling urgency, working memory often frees up for reading, coding, or conversation. Parasympathetic pathways linked to the vagus nerve may increase, lowering subjective stress ratings in many lab sessions.
That does not replace sleep, nutrition, or social support. It complements them. Track whether afternoon slumps shrink after a week of ten-minute sessions. Pair practice with daylight exposure—valuable during Dutch winters.
