Box Breath — Daily Vagal Tone
Five minutes of 4-4-4-4 box breathing each morning builds long-term HRV and shifts baseline autonomic balance toward parasympathetic.
Practise five minutes of 4-4-4-4 box breathing each morning to build long-term heart-rate variability and shift baseline autonomic balance toward the parasympathetic side. The effect is cumulative — daily consistency matters more than long sessions.

Four seconds in, four seconds hold, four seconds out, four seconds hold — that's box breathing.

The protocol
- Timing: morning preferred.
- Pattern: inhale 4 / hold 4 / exhale 4 / hold 4.
- Duration: 5 min.
- Frequency: daily.
What you get
- Improved vagal tone.
- Higher heart-rate variability (HRV).
- A calmer autonomic baseline.
Contraindications
- None — well-tolerated; stop if light-headed.
Evidence level
Medium. There is reasonable supporting evidence that slow paced breathing influences vagal tone and HRV; the size and durability of the effect varies between people.
