We breathe around twenty thousand times a day without thinking about it. Breathing is perhaps the only automatic function that we can also control consciously, and that makes it a powerful tool for influencing our state of mind. When we feel nervous, the rhythm speeds up and becomes shallow; when we breathe slowly and deeply, we send the body a signal of calm. Practising a few minutes a day can help you manage stress better.

What happens in the body when you breathe slowly

Slow breathing, especially with a longer exhalation than inhalation, activates the parasympathetic nervous system, which is in charge of rest and recovery. As a result, the heart rate tends to fall, muscle tension decreases and the mind settles. It is not magic but physiology, and it is backed by many studies on breathing and relaxation practices.

Before you start: general tips

  • Find a quiet place and take a comfortable position, sitting or lying down
  • If you wish, close your eyes or fix your gaze on a point
  • Breathe through your nose whenever possible
  • Do not force it: the exercise should feel pleasant, with no dizziness or tension
  • If you feel dizzy, return to normal breathing
  • Practise daily for a few minutes, better than a lot once a week

Exercise 1: diaphragmatic breathing

Place one hand on your chest and the other on your abdomen. Inhale slowly through your nose and let your abdomen expand, while the chest moves little. Exhale slowly through your nose or mouth, noticing how the abdomen contracts. Repeat for five minutes. This way of breathing uses the diaphragm, the main breathing muscle, and is the basis of other techniques.

Exercise 2: 4-6 breathing

Inhale through your nose counting to four. Exhale gently counting to six, with your lips slightly parted. The longer exhalation promotes relaxation. Do ten to twenty cycles. It is very useful before a meeting, an exam or when you notice tension rising.

Exercise 3: box breathing

Inhale for four seconds, hold the air for four seconds, exhale for four seconds and hold with empty lungs for another four. Repeat four or five times. It is used to recover concentration and calm in moments of pressure. If holding the air is uncomfortable, shorten the pauses or leave them out.

Exercise 4: alternate-nostril breathing

Sit with your back straight. With your right thumb close your right nostril and inhale through the left. Close the left with your ring finger, open the right and exhale through it. Inhale through the right, close it and exhale through the left. That is one cycle. Do between five and ten, at a gentle pace. This technique, from yoga, is associated with a sense of balance and stillness.

How to build it into your day

You do not need a long session. Try breathing with attention three times a day: on waking, mid-day and before sleep. You can also use everyday moments, such as waiting at a traffic light, the journey on public transport or the time it takes water to boil. Linking the exercise to a habitual action makes it a habit without effort.

Breathing and sleep

Practising slow breathing in bed, with the lights off, can help you fall asleep. Try the 4-6 pattern or abdominal breathing, and allow thoughts to pass without getting hooked on them. If you get distracted, kindly go back to counting breaths.

Myths and realities about breathing

It is said that deep breathing «oxygenates» the brain better and eliminates toxins, but the reality is simpler: you do not need more oxygen, but to change the rhythm to modulate your nervous system. Nor is there a single perfect technique; the best is the one you find comfortable and practise consistently. And there is no need to wait until you feel bad to use it: practising it when calm prepares you to apply it when you need it.

A simple record to see your progress

For two weeks, note each day how many minutes you practised, which technique you used and how you felt before and after, on a scale of one to ten. You will see clearly whether there are trends, whether it helps more in the morning or at night and which exercise works best. Seeing the data reinforces motivation and lets you adjust the practice to your needs.

Breathing and mindfulness

When you spend a few minutes breathing, try to notice specific sensations: the cool air entering the nose, the movement of the abdomen, the pause between one breath and the next. If the mind drifts to other thoughts, do not judge yourself; simply return. That repeated return, again and again, is itself the training of attention.

When to take care

People with respiratory or cardiovascular conditions, pregnancy or a history of panic attacks should practise with care and, if in doubt, consult a professional. If mindful breathing makes you anxious, shorten the duration, do not hold your breath and seek guidance.

Three minutes that change the day

Mindful breathing is free, always available and can be practised anywhere. Choose one exercise, give it three or five minutes a day for a week and watch how it changes the way you face stress. Sometimes the first step towards calm is as simple as stopping to breathe.
