Simple BreathworkBox breathing
Breathe in for four, hold for four, breathe out for four, hold for four. Box breathing is the easiest structured pattern to learn, and it's free every day in Simple Breathwork.
Box-breathing pacer (4-4-4-4)
The circle grows as you breathe in, stays full while you hold, shrinks as you breathe out and stays small for the last hold. The number counts down each side. If your device is set to reduce motion, the circle stays still and the words and numbers guide you instead. The pacer runs on this page only and sends nothing anywhere.
How to do box breathing
Sit upright in a chair or on the floor, shoulders relaxed, or lie down. Breathe through your nose if that's comfortable.
- Breathe in for four. A slow, quiet breath through the nose, filling from the belly up.
- Hold for four. Keep the throat soft. You're pausing, not clenching.
- Breathe out for four. Slowly, through the nose or gently through the mouth.
- Hold for four. Rest with empty lungs until the next breath in.
That's one box, about 16 seconds. Repeat for two minutes, or longer if it feels easy. When you finish, let your breathing return to normal and sit for a few breaths before you get up.
Why people like this pattern
The appeal of box breathing is that it's almost impossible to forget. Four equal sides, one number to count. It gives your attention something to do, which is often what a busy mind needs: you can't count to four four times while also rehearsing your inbox.
It also slows you down. A full box takes about 16 seconds, so you're breathing roughly four times a minute instead of the usual twelve to twenty. Many people find slow, even breathing helps them settle before a meeting, a hard conversation or sleep. That's a personal experience, not a promise, and box breathing isn't a treatment for any condition. If it doesn't feel good, there are other patterns.
Common mistakes
- Gulping the breath in. Four seconds is a slow breath. If you're full at second two, breathe in more gently.
- Straining on the holds. A hold should feel like a pause. If the empty-lung hold makes you gasp, shorten it to two seconds.
- Counting too fast. Counting tends to speed up. That's why a pacer or the app's haptics help: the timing stays even.
- Doing it while driving. Slow breathing is fine anywhere, but don't use any breathing practice with holds behind the wheel, and don't close your eyes anywhere that isn't safe.
Box breathing vs other patterns
Box breathing uses equal counts. Other patterns change the ratio. The 4-7-8 pattern uses a longer hold and an even longer breath out. The physiological sigh uses a double inhale and one long exhale, with no hold at all, and takes only a few breaths. None is the right one. Pick the one you'll actually do. If you're new to all of this, start with the beginner's guide to breathwork.
Box breathing is very different from power breathing with breath holds. It's slow and steady, with short pauses. Power-breathing rounds involve fast, deep breathing and long holds, which carry real fainting risk. Don't confuse the two.
Box breathing in Simple Breathwork
Box Breathing is free in Simple Breathwork every day, no account needed. It sits alongside the free Start Fresh session, a guided two-minute reset that opens the app. Each phase is guided with haptics and soft tones, so you can keep your eyes closed and let your phone, or your Apple Watch, keep the count for you.
If you turn on Apple Health, completed sessions are saved as Mindful Minutes. Your sessions also count toward your streak and weekly practice in the app's analytics. Premium adds more guided sessions, including programs like the 21-day program.
A simple way to make it stick
Pick one moment you already have every day: after you sit down at your desk, before you open your laptop, or when you get into bed. Do one two-minute box there. A practice that takes two minutes is one you can keep on a busy day, and a workday reminder in the app can nudge you at the same time each day.
Questions
What is box breathing?
Box breathing is a paced breathing pattern with four equal parts: breathe in, hold, breathe out, hold. Each part usually lasts four seconds, so one cycle takes 16 seconds. It's also called square breathing or 4-4-4-4 breathing.
How long should I do box breathing for?
Two to five minutes is a good start. That's roughly eight to twenty cycles. Shorter is fine if the holds feel uncomfortable.
Is box breathing free in Simple Breathwork?
Yes. Box Breathing is one of the two sessions that are free every day, along with the Start Fresh two-minute reset. No account is needed.
What if four seconds feels too long?
Use three seconds per side, or shorten the holds. The pattern matters less than breathing slowly and comfortably. Stop if you feel light-headed.
Can I do box breathing with my eyes closed?
Yes. In the app, haptics and soft tones mark each phase, so you can follow the box without looking. On Apple Watch, the taps come from your wrist.
