Ten evidence-based patterns, sorted by goal. Tap one, follow the breathing orb, feel the shift in three minutes.
A breathing exercise is a structured pattern of inhales, exhales, and pauses, practised deliberately to change how your body and mind feel — most commonly to lower stress, improve sleep, sharpen focus, or build respiratory stamina.

Breathing is the only autonomic function you can take over consciously. That is why a 3-minute breathing exercise can shift your heart rate, blood pressure, mood, and mental clarity in ways that almost no other 3-minute intervention can.

• **To calm down right now:** 4-7-8 or the physiological sigh (one round, 30 seconds).
• **To fall asleep:** 4-7-8 for 4–8 cycles in bed.
• **To focus:** box breathing for 2–3 minutes before a task.
• **To lift mood:** 5 minutes of cyclic sighing.
• **To build daily resilience:** 10 minutes of coherent (5-5) breathing.
• **To energise:** 1 round of Wim Hof breathing in the morning.
• **To retrain how you breathe all day:** diaphragmatic breathing, 5 minutes twice daily for 4 weeks.
Three variables determine the effect of any breathing exercise:
Rate — 5–6 breaths per minute is the resonance zone where HRV is maximised. Slower is calmer.
Ratio — a longer exhale than inhale activates the vagus nerve. A 1:2 exhale-to-inhale ratio is the calmest.
Route — nasal breathing releases nitric oxide (a vasodilator), filters air, and naturally slows the rate. Mouth breathing should be reserved for high-effort exhales (4-7-8, pursed-lip).
A good breathing exercise sets all three deliberately. Random "take a deep breath" advice does not.
1. Sit upright, feet flat, hand on belly.
2. Inhale through the nose for 4 seconds — belly hand rises, chest hand stays still.
3. Exhale through pursed lips for 6–8 seconds.
4. Repeat for 3 minutes. If lightheaded, breathe more shallowly, not slower.
That single 3-minute habit, done twice a day, measurably lowers resting heart rate and perceived stress within 2 weeks.

• **Breathing too deeply.** You blow off CO₂ and feel dizzy, tingly, or more anxious. Reduce volume.
• **Forcing the count.** If 4-7-8 feels strained, drop to 3-5-6. Ratio matters more than absolute seconds.
• **Mouth breathing on the inhale.** Defaults to nose unless the technique specifies mouth.
• **Doing it once and judging.** Most exercises show their full effect after 2–4 weeks of daily practice.
Yes for most healthy adults. Skip breath holds and Wim Hof-style hyperventilation if you are pregnant, have uncontrolled hypertension, epilepsy, or a heart condition. Anyone with COPD, asthma, or a respiratory diagnosis should follow technique-specific guidance (pursed-lip and diaphragmatic breathing are safe; rapid power-breath methods are not).
