Box Breathing Timer: Free 4-4-4-4 Exercise

What is box breathing?

Box breathing is a simple breathing pattern with four equal steps: breathe in, hold, breathe out and hold again, each for the same count, usually 4 seconds. Picture tracing the four sides of a square, which is where the name comes from. It is also called square breathing, four-square breathing or 4-4-4-4 breathing.

It needs no equipment and takes only a few minutes, so it fits easily into a short break at your desk. The steady count gives your mind something simple to focus on, and slowing your breath down is one of the easiest ways to take a calm pause in a busy day.

How to do box breathing

Sit comfortably with your feet on the floor and your shoulders relaxed. Close your eyes or rest your gaze.
Gently breathe out all the air in your lungs.
Breathe in slowly through your nose for a count of 4, letting your belly rise.
Hold your breath for 4, keeping your shoulders and jaw relaxed.
Breathe out slowly for 4, through your nose or slightly parted lips.
Hold again for 4 before the next breath in.
Repeat for a few minutes, then go back to breathing normally.

How to use this box breathing timer

Press Start breathing. The dot sets off along the top of the square.
Follow it around: breathe in along the top, hold down the right side, breathe out along the bottom and hold up the left side.
The big number counts down each side, and the inner square grows as you breathe in and shrinks as you breathe out.
Turn on the sound cue to follow with your eyes closed. The session ends after a full round, and finished sessions count toward your daily total and streak.
Change the count or the session length in the settings, and turn on the reminder if you would like a nudge during your active hours.

Why take a box breathing break at work?

Many people find that a few minutes of slow, even breathing helps them feel calmer and more focused, and research on structured breathing points the same way. In a 2023 Stanford study, about 110 volunteers spent five minutes a day for a month on box breathing, another breathing exercise or mindfulness meditation. All the groups reported a better mood and less anxiety. It was a small study, but it suggests that a short daily pause to breathe slowly is worth trying.

Good moments for a box breathing break include:

before a meeting, a presentation or a difficult conversation
after a stressful call or email
when you switch from one task to the next
at the end of the working day, to help you switch off

Tips for box breathing

If 4 seconds feels long, start with 3 a side. You can try 5 or 6 later if that feels comfortable.
Keep the holds relaxed. Don't clench your throat or strain to keep the air in.
Breathe low into your belly rather than lifting your shoulders.
Combine it with an eye break: the 20-20-20 timer reminds you to look away from the screen, and a minute of box breathing fits neatly into the same pause.
For a slower pattern with a longer breath out, try 4-7-8 breathing: breathe in for 4, hold for 7 and breathe out for 8.
Start a meditation with a minute of box breathing, then stay still for a few minutes more with the meditation timer.
Stop and breathe normally if you feel dizzy or light-headed.

Is box breathing right for you?

Box breathing is gentle, and most people can do it safely. Check with a doctor first if you have a heart or lung condition such as asthma or COPD, are pregnant, or have been told to avoid holding your breath. You can always shorten the count or the holds.

It is a way to take a calm pause, not a treatment. If stress, anxiety or panic attacks are affecting your daily life, talk to a doctor or a mental health professional.

Frequently asked questions

How long should I do box breathing for?

A few minutes is plenty. Four rounds take about a minute at 4 seconds a side and make a quick reset; three to five minutes make a calmer break.

This timer starts with 4 minutes, which is 15 rounds at 4 seconds a side. You can set anything from 1 to 20 minutes, and a session always finishes at the end of a full round.

Is box breathing the same as square breathing or 4-4-4-4 breathing?

Yes. Box breathing, square breathing, four-square breathing and 4-4-4-4 breathing are names for the same pattern: breathe in, hold, breathe out and hold again, each for the same count.

What if holding my breath for 4 seconds feels uncomfortable?

Use a shorter count. Set each side to 3 or even 2 seconds in the exercise settings, and build up later if you want to. The holds should feel relaxed, never like a strain.

If you feel dizzy or light-headed, stop and breathe normally for a while.

Should I breathe through my nose or my mouth?

Most guides suggest breathing in gently through your nose and out through your nose or slightly parted lips. Use whatever feels comfortable and lets you breathe slowly and quietly.

Can I do it with my eyes closed?

Yes. Turn on the sound cue in the exercise settings: a rising tone means breathe in, a falling tone means breathe out, and a short, level tone means hold. A soft chime plays when the session is complete.

The cues need sound to be on in your Supabreak settings, and they keep time even when the tab is in the background.

How do the box breathing reminders work?

Turn on the reminder and choose how often, from every 15 minutes to every 4 hours. Supabreak sends a notification during your active hours, and clicking it brings you back to this page.

Finishing a session restarts the countdown, so you are not reminded straight after a break. Like every Supabreak reminder, it only works while a Supabreak tab or the installed app is open.

Is box breathing suitable for everyone?

For most people it is a gentle exercise, but check with a doctor first if you have a heart or lung condition, are pregnant, or have been told to avoid holding your breath. You can also shorten the holds.

Box breathing is a way to take a calm pause, not a treatment for anxiety, panic attacks or any other condition. If stress or anxiety is affecting your daily life, talk to a doctor or a mental health professional.
