Slow breathing (6 breaths a minute)
Breathing in gently for about 4 seconds and out for about 6, with no holds: about 6 breaths a minute. It is the slow, gentle breathing the NHS suggests for stress, and it raises heart rate variability, a sign of the calming side of the nervous system, while you do it. It is a calming tool, not a treatment for an anxiety disorder.

How to move
- Sit with your back supported and both feet flat, or lie down. Loosen anything tight around your waist, and rest one hand on your belly and the other on your lower ribs.
- Breathe in gently through your nose for a count of about 4, letting your belly and lower ribs widen.
- Breathe out slowly through your mouth or nose for a count of about 6. Let the air go rather than pushing it out.
- Go straight into the next breath in. There are no holds.
- Keep each breath small and quiet, and carry on for 5 minutes. If 4 and 6 feel long, count 3 in and 4 out, or 5 in and 5 out as the NHS does.
Form cues
- Slow, not big: the breath should be quiet.
- Let the out-breath be as long as the in-breath, or a little longer.
- Avoid: gulping air or lifting the shoulders. If you feel light-headed or tingly, make the breaths smaller.
Practice and cautions
At least 5 minutes, done regularly as part of your daily routine: the NHS breathing exercise for stress, which counts 1 to 5 in and 1 to 5 out. Once or twice a day, plus whenever you feel anxious, is an editorial starting point. The 4-in, 6-out count is one of the two 6-breaths-a-minute patterns in Marchant 2025, which raised heart rate variability more than box or 4-7-8 breathing; none of the three changed mood in a single session. Across 20 trials, breathing exercises reduced anxiety by a small amount, and in panic disorder, adding breathing training to CBT added nothing in one trial.
If you feel dizzy, light-headed or tingly, you are probably breathing too deeply: make the breaths smaller or go back to normal breathing. If you have a lung condition, follow the breathing advice your own team gives you. Slow breathing can help you through a panic attack, but chest pain, fainting, or palpitations that don't settle need urgent help: call 999. This is movement education, not an assessment or treatment prescription. Stop for sharp or increasing pain, dizziness, numbness or tingling; seek individual guidance for symptoms, injury or restrictions.
