Breathe in for 4 seconds, rest for 2, and release the breath for 6 seconds with a soft "Hûûû".
The Hû breath comes from the Sufi tradition, where "Hû", a word meaning "He" that points to the Divine, is repeated in dhikr, the practice of remembrance. Here it is offered simply as a sound breath: a gentle inhale, a brief pause, and an exhale carried by an open, airy "Hûûû". You can approach it as a spiritual practice or as a calming voice exercise; both are welcome.
The Hû breath suits quiet moments of reflection: early morning, before prayer or meditation, or in the evening when you want to gather yourself. Slow ney or Sufi music in the background can deepen the atmosphere. It is also a gentle option if you like the idea of a sounding breath but prefer an open, airy tone to a closed-mouth hum.
Breath and sound run through Sufi practice: in dhikr gatherings the name Hû is often voiced rhythmically, sometimes with movement, as a way of turning the heart towards remembrance. This is a traditional and devotional practice, and there is no scientific research on the Hû breath as such. What it shares with studied techniques is a slow pace and a long, voiced exhale, both of which are associated with a calmer state.
Practice sitting or lying down; never in water or while driving. Stop if you feel dizzy.
Keep the sound soft and relaxed, without pushing from the throat. If you feel light-headed, take a few normal breaths before continuing.
