Breathing is the only function of the autonomic nervous system that we can also control consciously. The heart beats, the stomach digests, body temperature regulates itself — all of that happens without us deciding anything. But breathing can be left on autopilot, or it can be taken over deliberately. That quirk makes it a kind of back door: a direct way to influence the nervous system.
Five minutes to shift gears
You don't need to be anxious to practise guided breathing. It can also be used before studying, writing, working, or facing any task that demands concentration. Slow breathing reduces physiological activation. And some studies have found short-term improvements in working memory and mood.
It can help you:
- Quiet the mental noise before starting.
- Focus your attention on a single task.
- Reduce activation and stress.
- Improve the conditions for working memory.
- Create a small transition between scattered and focused.
Here are five slow-breathing patterns, from simplest to most demanding. All you need is five minutes: no mat, no special clothes, no time you don't already have.
Five minutes, but tomorrow too
Changing a habit requires repetition and attention: with practice, the brain reinforces new ways of responding, and calm can become more accessible. Just as with yoga, consistency matters more than intensity: five minutes a day usually gives you more than one long, occasional session.
Benefits
In the short term, slow breathing can:
- Reduce the respiratory rate and, in some cases, the heart rate.
- Increase heart rate variability (HRV), associated with better regulation of the autonomic nervous system.
- Promote parasympathetic activity, linked to states of rest and recovery.
- Reduce physiological activation and the sensation of stress or anxiety.
- Focus attention, by giving the mind a simple, repetitive task.
With regular practice, it may help to:
- Improve autonomic regulation, making it easier to shift from a state of activation to one of greater calm.
- Reduce perceived stress and anxiety in some people.
- Improve certain cardiovascular parameters, such as blood pressure, especially where hypertension is present.
- Train attention and body awareness, by learning to recognise signs of tension or agitation earlier.
