Ancient Yogic Wisdom

Pranayama: The Art of Breath Control

Traditional breathing practices from yoga, refined over thousands of years. “Prana” means life force, “yama” means control. For the two most asked about, we have a dedicated anulom vilom timer and a rundown of bhastrika breathing apps.

Bhastrika

Bellows Breath

4-2-4-2 by default, Fast 2-1-2-1

Full, forceful breaths in and out through the nose, paced as deliberate breaths rather than rapid bellows.

Benefits: Energising. A slow-paced form lowered blood pressure in one study, and a month of daily practice improved lung function measures in another. Traditionally used to prepare for meditation.
Best for: Energy boost, morning practice1, 2, 5, 10 minutes

Kapalbhati

Skull Shining Breathing

One exhale per second (Slow and Fast settings)

Short, powerful exhales driven by the belly, with passive inhales. On the watch, one tap marks each exhale.

Benefits: Activating while you practise: heart rate variability shifts toward arousal during Kapalbhati, and toward rest about 20 minutes later. Claims about detox and weight loss are not supported by controlled trials.
Best for: Morning energy, alertness2, 5, 10, 25, 40 minutes

Anulom Vilom

Alternate Nostril Breathing

4-2-6-2 by default, Fast 2-1-3-1

Breathe through one nostril at a time, alternating sides, switching during each pause.

Benefits: In controlled studies, breathing rate and systolic blood pressure fell during practice while heart rate variability rose. One of the gentlest pranayamas.
Best for: Balance, stress relief, mental clarity1, 2, 5, 10, 15 minutes
