Calm breathing when tense: belly breathing

General information, not medical advice.

Breathing adapts on its own: calmer at rest, faster and deeper with effort. If you breathe faster or deeper than your body needs, people speak of a disturbed breathing pattern. Hyperventilation is breathing too much. Incorrect or dysfunctional breathing is a broader term and covers more than that alone. That is the line of the Gezondheid en Wetenschap (Cebam) guideline.

What tension does to your breath

Your breathing follows what is happening in your body. At rest it is slow and deep; with tension or panic it often becomes faster and higher.

With anxiety or panic you breathe faster. That often makes you feel even more anxious, and that speeds your breathing up again. Chronic tension can lead to breathing mainly through the chest and little through the belly, or faster than usual: more than 12 to 16 times a minute, the guideline writes. You do not always notice those signals straight away.

A hyperventilation attack without an underlying condition is, according to that guideline, not dangerous and passes on its own. Such an attack is frightening, though. If you learn to recognise it, you avoid the anxiety speeding the breathing up even more.

Belly breathing as a calm exercise

Practise that calm breathing preferably first at a calm moment, so you find it more easily later when tension rises. If you notice your breath sitting high in the chest, that is often a signal to slow down a bit.

During a panic attack, the guideline advises breathing calmly through the belly, not through the chest. Put your hands on your belly: it should go up and down with every breath. A concrete rhythm: 3 seconds in and 6 seconds out. If focusing on your breath does not help, seek distraction and let your breathing gradually become spontaneous again.

Gezond Leven has the Adempauze method for schools: an exercise for secondary-school pupils, not tailored advice for adults. Young people learn to imagine a balloon in the belly, breathe in through the nose and out through the mouth, and later to count, for example 4 seconds in, 1 second hold, 4 seconds out. That mainly illustrates that belly breathing exists and can bring calm; it is not a medical treatment.

Anyone who regularly has shortness of breath or tingling when tense often recognises the same pattern: breathe faster, more anxiety, breathe even faster. A short spell of belly breathing sometimes breaks that rhythm enough to think clearly again. If that does not work, or the attacks keep coming back, that is a reason to seek professional help.

When to see a doctor?

If you hyperventilate regularly, with or without a panic attack, or you doubt something else is going on, discuss that with your GP or a psychologist. With sudden severe shortness of breath, chest pain or fainting, seek medical help at once (112 if needed).

On sleep and evening calm, read more in the article on lying awake and on your phone outside the bedroom.
