Breathing Before a Presentation

Three minutes of slow breathing with a long exhale, then one long breath out before your first sentence.

For breathing before a presentation, find a quiet spot about 10 minutes ahead and breathe in through your nose for 4 seconds and out for 6, for 3 minutes. That is six breaths a minute. In the last minute, take two or three slow breaths with a long exhale. At the lectern, breathe out once, fully, before your first sentence.

Ten minutes before

Go somewhere you can be alone for a few minutes: a corridor, a stairwell, a bathroom stall, your car. Run the timer above for three minutes at 4 seconds in and 6 seconds out.

  1. Stand or sit upright. Unclench your jaw and let your shoulders drop.
  2. Breathe in through your nose for 4 seconds. An ordinary breath, nothing deep.
  3. Breathe out for 6 seconds, through your nose or through softly pursed lips.
  4. Keep going for 3 minutes. That is 18 breaths.

Do not expect much from the first minute. Somewhere in the second or third, many people notice their shoulders come down and their heartbeat ease off a little. You will still be nervous, and that is fine. The aim is to take the edge off, not to feel nothing.

If you have never done this before, practice it once or twice in the days before.

One minute before

By now you are probably sitting in the room, or waiting on a video call with your camera on. A timer is not an option, so do it quietly: two or three breaths, in through the nose, out slowly and for longer than you breathed in. Nobody will notice.

If you are out of sight, a sigh is better still. Breathe in through your nose, add a short second sniff on top, then let it all out through your mouth in one long breath. Two or three of those is enough. More on that at the cyclic sighing timer.

Don't take big gulping breaths to "get oxygen". That is over-breathing, and it brings on light-headedness and tingling hands, which you do not want right before speaking.

At the lectern

Walk up, put your notes down, look at the room. Then breathe out, slowly and fully, before you say a word.

This is the single most useful habit on this page. Nervous speakers tend to start on a held breath, high in the chest, and the first sentence comes out thin and fast. If you empty your lungs first, the next breath in happens by itself and it is a low, full one. The pause feels very long to you. To the audience it is about three seconds and looks like composure.

During the talk, breathe at the full stops. When you lose your thread, a slow breath out buys you time and reads as a deliberate pause.

Long exhale or box breathing

Box breathing is often recommended for nerves before a performance: in 4, hold 4, out 4, hold 4. It is a good exercise, and it is the second option in the timer. But the one direct comparison we know of points the other way for this situation.

A 2021 study compared tactical (box) breathing with prolonged exhalation in people doing a task under stress. Box breathing lowered physical arousal more. The long exhale group did better on the task itself. That is one study, so hold it loosely. Still, a presentation is a task you have to perform, which is why the long exhale is the default here.

Box breathing may suit you better if your nerves are mostly physical, such as shaky hands or a pounding heart, or if you like having a strict count to hold on to. Try both on an ordinary day and see. The box breathing timer has an easier 3-second pace.

Interviews, exams and other moments

The same plan works anywhere you have to perform on the spot.

  • Job interview: do the three minutes before you walk into the building or join the call, not in the waiting room. Breathe out once before you answer the first question.
  • Exam: three minutes outside the hall. When your mind goes blank halfway through, put the pen down for three slow breaths.
  • Toast, pitch or hard conversation: skip straight to the last two steps. A few long exhales, then one more before you start.

For staying sharp through a long session, see breathing exercises for focus. If the nerves start the night before, how to breathe to calm down covers that.

If you feel dizzy or tingly, you are breathing too much. Stop and breathe normally; it passes within a minute. If you use box breathing, keep the holds comfortable, and skip them if you are pregnant or have a heart or blood pressure condition.

Questions people ask

How do I calm my nerves before a presentation?

About 10 minutes before, breathe in for 4 seconds and out for 6 for 3 minutes. In the last minute take two or three slow breaths with a long exhale, and breathe out fully once before your first sentence.

How long before a presentation should I do breathing exercises?

Around 10 minutes before works well. It leaves time for a 3-minute session and a calm walk to the room. Add a few slow breaths in the final minute.

Is box breathing good before public speaking?

It can be. In a 2021 study box breathing lowered physical arousal under stress, while a prolonged exhale led to better task performance. Try both on an ordinary day and use the one that suits you.

Why make the exhale longer than the inhale?

A 2014 study found that a longer exhale than inhale adds to the relaxing effect of slow breathing. A pattern of 4 seconds in and 6 out also has no holds, so it is easy to do unnoticed.

What if I run out of breath while I am speaking?

Stop at the end of the sentence, breathe out, and let the next breath come in through your nose. Running out of air often comes from speaking fast on shallow breaths, and a short pause usually sorts it out.

Can I do this in the room without anyone noticing?

Yes. Breathe in through your nose and out slowly through your nose, a little longer than you breathed in. There is nothing to see or hear.
