Formula used
- Seconds per cycle = inhale + hold after inhale + exhale + hold after exhale
- Total seconds = seconds per cycle × cycles
- Total duration = total seconds converted to mm:ss
- Approx pace (breaths/min) = 60 ÷ seconds per cycle

Breathing insights
Breathing cadence and nervous system settling
Slow, structured breathing can support a calmer physiological state by smoothing the rise and fall of carbon dioxide and reducing the sense of urgency in respiration. This timer is designed for steady practice, not performance, helping you keep attention on rhythm and comfort. Common starts are 3–6 seconds per phase, yielding 10–20 second cycles.
Timing parameters and calculated session totals
The calculator sums inhale, optional holds, exhale, and the second hold to get seconds per cycle. Total seconds equal cycle seconds multiplied by cycles, then formatted as mm:ss. The pace estimate uses 60 divided by cycle seconds to show an approximate breaths‑per‑minute value. Example: 4‑0‑6‑0 is 10 seconds; 12 cycles equals 120.
Presets as evidence‑informed starting points
Built‑in presets provide reliable patterns. Box breathing uses equal counts to emphasize control and symmetry. Relaxing exhale extends the out‑breath, which many people find useful for downshifting tension. Coherent breathing balances inhale and exhale for a simple, repeatable cadence. 4‑4‑4‑4 is 16 seconds per cycle, about 3.75 bpm.
Consistency tracking with exportable session logs
Regular practice benefits from simple records. The example table models a minimal log with date, preset, pattern, cycles, duration, and a short note. CSV export captures your current inputs and computed results for spreadsheets, while PDF export creates a shareable one‑page summary. Logging two sessions weekly can reveal patterns in mood, sleep, and focus.
Visual pacing cues and phase distribution chart
The animated circle offers a nonverbal cue: expansion for inhale and a smaller shape for exhale phases. The Plotly bar chart aggregates total seconds spent in each phase across the whole session, making it easy to see how holds change the overall distribution of time. Zero inhale still runs, but the pace estimate becomes unreliable.
Practical use cases for daily mental fitness
Use the tool before demanding tasks, after stressful moments, or as a short transition between activities. Start with comfortable durations, keep holds optional, and increase only when the pattern feels easy. If lightheadedness appears, pause and return to natural breathing. A two‑minute session often fits breaks; a five‑minute session suits winding down.
FAQs
What is one breathing cycle in this timer?
One cycle equals inhale plus any holds, then exhale plus the final hold. The tool repeats that full pattern for your selected number of cycles, showing total duration and pace.
Which preset should I start with?
If you’re new, try Coherent (5‑0‑5‑0) or Relaxing Exhale (4‑0‑6‑0). If you want structure and equal counts, use Box (4‑4‑4‑4). Keep everything comfortable.
Why does the breaths‑per‑minute number look low?
Structured cycles are longer than casual breathing. The estimate is 60 divided by seconds per cycle, so adding holds or lengthening exhale reduces the pace. That’s normal for calming patterns.
Can I use zero for a phase time?
Yes. Setting a phase to zero skips it in the schedule. If inhale becomes zero, the pace estimate may be less meaningful, so focus on total duration and comfort instead.
How do the CSV and PDF downloads differ?
CSV exports your inputs and computed metrics in a spreadsheet‑friendly format. PDF creates a clean, shareable summary page and attempts to embed the phase‑time bar chart.
What if I feel dizzy during a session?
Stop the timer, sit comfortably, and return to natural breathing. Shorten exhale and remove holds next time. If dizziness repeats or you have health concerns, seek professional advice.
