Box Breathing, 4-7-8 & Coherent Breathing
Slow, deliberate breathing is one of the fastest ways to shift how you feel. A longer, controlled breath — especially a longer exhale — nudges your parasympathetic nervous system (the "rest and digest" side) and can lower your heart rate and stress within a minute or two. Here are three patterns worth knowing.
1. Box breathing (4·4·4·4)
Inhale for 4, hold for 4, exhale for 4, hold for 4 — like tracing the four sides of a box. It's balanced and steadying, which is why it's a favourite for focus and composure under pressure (it's often called "Navy SEAL breathing"). Great before a meeting, exam or anything nerve-wracking.
2. 4-7-8 breathing
Inhale for 4, hold for 7, exhale slowly for 8. The extended hold and long exhale make this the most relaxing of the three — popularised by Dr. Andrew Weil as a way to wind down and fall asleep. Try a few rounds lying in bed. If holding for 7 feels like a strain at first, shorten everything proportionally (say 2-3.5-4) and build up.
3. Coherent breathing (5·5)
Five seconds in, five seconds out — about six breaths per minute, with no holds. This resonant pace is associated with better heart-rate variability and a settled, balanced feeling. It's gentle enough to do for 5–10 minutes as a daily reset, and it's the easiest to sustain.
Which one should you use?
- Need to focus or steady your nerves? Box breathing.
- Trying to relax or sleep? 4-7-8.
- Want a calm daily baseline? Coherent 5-5.
How to practice
Sit or lie comfortably with a tall spine. Breathe into your belly (it should rise more than your chest), ideally in through the nose and out through the mouth. Keep it easy — breathwork should feel calming, never forced. Start with 2–5 minutes. The hardest part is remembering the counts, which is exactly what a guided pacer takes care of.
Frequently asked questions
Which breathing exercise is best for anxiety?
A longer exhale than inhale calms the nervous system, so 4-7-8 and coherent 5-5 are popular for anxiety and winding down. Box breathing is better when you need steady focus.
How long should I do breathwork?
Even 1–2 minutes helps. A common routine is 5 minutes of coherent breathing once or twice a day, or a few rounds of 4-7-8 before sleep.
Is box breathing safe?
For most people, yes — it's gentle. Keep it comfortable, don't strain the holds, and stop if you feel dizzy. Check with a doctor if you have a heart or breathing condition.
Do I have to count myself?
No. A guided breathing tool shows an orb that grows and shrinks with each phase, so you just follow along.
