If you are in a C-PTSD panic or flashback, your body can flip into survival mode before you even know what is happening. Heart racing, chest tight, brain full of static. You might feel like you are about to die, collapse, or lose control.
You are not weak for reacting this way. Your nervous system is replaying old danger. Box breathing is one simple pattern you can use to signal to your body, "I am here now," and start calming the panic in about 90 seconds.

What is box breathing and why can it help C-PTSD panic?
Box breathing is a breathing pattern with four equal parts, like the sides of a square:
- Breathe in
- Hold
- Breathe out
- Hold
Each part uses the same slow count, usually 4 counts. This rhythm tells your nervous system that it does not need to stay in full alarm mode. Your heart rate can start to drop, your muscles can unclench, and your brain can get enough oxygen to think a little more clearly.
For C-PTSD, the point is not perfect timing. The point is to give your body a simple, repeatable pattern that is stronger than the chaos of the flashback.
How to do box breathing in 90 seconds
You can do this sitting, standing, or even while walking slowly. You do not need privacy, a yoga mat, or special skills.
Step 1: Get into a "good enough" position
- If you are at home, sit with your feet on the floor and your back supported.
- At work, sit at your desk or step into a bathroom stall.
- In public, stand or sit where you are and let yourself soften your shoulders a little.
You do not have to close your eyes. If closing your eyes makes you feel unsafe, keep them open and rest your gaze on one neutral spot.
Step 2: Choose your count
Most people use a count of 4. If that feels too long or you feel short of breath, use 3. Pain is not the goal. Comfort is.
Step 3: Breathe in a box
Do one round at your chosen count:
- Inhale through your nose for 4 counts.
- Hold your breath gently for 4 counts.
- Exhale through your mouth for 4 counts.
- Pause with empty lungs for 4 counts.
This takes about 16 seconds. In 90 seconds, you can usually complete 4 or 5 rounds.
Step 4: Notice even tiny changes
As you repeat the pattern, quietly check in:
- Is my breath a little smoother than when I started?
- Did my shoulders drop even a few millimeters?
- Does the panic feel one percent less sharp?
You do not need a dramatic shift for box breathing to be "working". Small changes matter.
How to use box breathing at home
At home you often have more space to experiment. You can:
- Put your feet flat on the floor and press your toes down during the holds.
- Rest one hand on your chest and one on your belly to feel the movement.
- Pair box breathing with a simple grounding sentence, such as, "I am on my couch, in my home, in this year."
You can also set a 90 second timer on your phone so you do not obsess over the clock. Tell yourself, "For this minute and a half, my only job is to follow the box."
How to use box breathing at work
At work, you may need box breathing that looks normal on the outside. You can:
- Keep your eyes open, look at your screen or a neutral object, and count in your head.
- Let your breath be slow but quiet so it sounds like regular breathing.
- Use your breaks or bathroom trips for two or three focused minutes of box breathing.
If you are in a meeting and panic hits, you can lower your gaze, gently unclench your jaw, and run a few rounds of 3-count box breathing while others talk. No one has to know what you are doing.
How to use box breathing in public
Panic and flashbacks can hit on the bus, in a lineup, at a store, or walking down the street. In public, safety and subtlety matter.
You can:
- Focus on feeling your feet in your shoes while you run the inhale-hold-exhale-hold pattern.
- Sync the counts with your steps if you are walking. For example, inhale for 4 steps, hold for 4, exhale for 4, hold for 4.
- Rest your hand lightly on a bag or your leg so you notice the sensation as you breathe.
If you feel lightheaded, shorten the holds or switch to a gentler pattern like "inhale for 4, exhale for 6" without holding your breath.
Common problems and how to adjust box breathing
"Holding my breath makes me more anxious."
- Use a count of 3 or even 2.
- Or skip the holds and simply do "inhale 4, exhale 4" at a slow pace.
"I feel dizzy."
- Slow your breathing down, do not force huge inhales.
- Sit down if you can, and pause the holds until the dizziness settles.
"I cannot keep track of the counts when I am panicking."
- Count only the inhale and exhale.
- Let the holds be as short as a comfortable pause.
- Use an app that visually guides the box so you can follow the shape instead of counting numbers in your head.
Using an app like Unpanic to guide box breathing
When your brain is foggy, having the steps on screen helps. In an app such as Unpanic, you can:
- Tap a "box breathing" exercise that shows a simple shape filling and emptying.
- Follow the animation instead of tracking your own counts.
- Combine box breathing with other C-PTSD tools like 5-4-3-2-1 grounding and crisis links.
Practicing with the app on calmer days trains your body. Then when a flashback hits, you are not learning a new skill from scratch, you are using a pattern your nervous system already recognizes.
When to move from box breathing to more help
Box breathing is a tool, not a full treatment. If you notice any of this, reach out for more support:
- Panic or flashbacks are getting stronger and more frequent.
- You have thoughts about not wanting to exist or hurting yourself.
- Nervous system symptoms are making it hard to work, study, or care for yourself.
Contact a trauma informed therapist, doctor, peer group, or crisis service. You deserve more than survival tools. You deserve care.
FAQ: Box Breathing For C-PTSD Panic
Is box breathing safe if I have C-PTSD and panic attacks?
For most people, yes. Box breathing is a gentle pattern that helps calm the nervous system. If breath holds feel scary or uncomfortable, you can shorten them or remove them. Always listen to your body.
How long should I do box breathing during a flashback?
Start with about 90 seconds, which is usually 4 to 5 rounds. If you feel a bit calmer, you can continue for a few more minutes. If you feel worse, adjust the pattern or stop and try another grounding tool.
Can I do box breathing lying down?
Yes, as long as you can breathe comfortably. Some people prefer sitting so they do not associate lying down with panic. Experiment and see what feels safest.
What if I cannot inhale deeply because of chest tightness?
Keep the inhale small and comfortable. Box breathing is not about big perfect breaths. You can also try a 3-count pattern until your chest loosens.
Should I practice box breathing only when I panic?
It helps to practice once or twice a day when you are not in crisis. This makes the pattern familiar, so it is easier to access in the middle of a flashback or panic episode.
