Can Breathing Exercises Make Anxiety Worse? Why It Happens
Quick answer: Yes, for some people, and it usually comes down to one of three things: anxiety sensitivity (attending to bodily sensations amplifies them), the instinct to take a big deep breath (which activates the sympathetic branch and drops CO2 further if the exhale isn't extended), or the wrong technique for an anxious nervous system (rapid hyperventilation-style breathing and long breath holds). None of the three means breathwork won't work for you. They mean the entry point has to be different: short sessions, extended exhale only, external focus, and no holds until anxiety is settled.
You did the thing everyone recommends. You sat down, you breathed, and you felt worse — more aware of your chest, more aware of your heartbeat, closer to panic than when you started.
This is common, it is physiological rather than a failure of effort, and it is fixable. But the standard advice — "just breathe" — is exactly what causes it in a meaningful number of anxious people, so repeating that advice louder does not help.
This page is about the backfire: the three mechanisms behind it, the techniques most likely to trigger it, and how to build a practice that works around it. For the mechanisms by which breathwork for anxiety helps in the first place — the evidence, the CO2 hypothesis, the technique-by-technique breakdown — start there and come back here if it backfires on you.
Mechanism 1: Anxiety Sensitivity
Anxiety sensitivity is the tendency to fear physical sensations — to read a fast heartbeat or a tight chest as evidence that something is wrong. It is one of the better-documented features of anxiety disorders, and it explains most reports of breathing exercises going wrong.
Breathwork asks you to pay close attention to your body. For someone with high anxiety sensitivity, the act of attending to bodily sensations amplifies them. You notice your heartbeat, the noticing makes it feel louder, the loudness reads as danger, and the alarm you sat down to quiet is the thing you have just turned up.
This is not a reason to avoid breathwork. It is a reason to change where your attention goes during it — which is covered further down.
Mechanism 2: The Big Deep Breath
The most common instinct when anxiety spikes is to take a big deep breath. It is also one of the most reliable ways to make the moment worse:
- A forced deep inhale activates the sympathetic branch — the same branch anxiety is already running.
- If the exhale isn't extended to match, the breath moves more air per minute, and CO2 drops further.
- The chest expansion itself produces a stretched, full sensation that is easy to misinterpret as chest tightness.
That last point matters more than it looks. The physical sensations of over-breathing — dizziness, tingling, tightness, a pounding heart — are real, and they are the same sensations anxiety produces. Anyone who reads them as evidence of danger gets a second wave of anxiety on top of the first.
The correction is simple and it is the whole of the acute intervention: focus on the exhale, make it long, make it slow, and let the inhale happen by itself.
Mechanism 3: The Wrong Technique for an Anxious Nervous System
Not every breathing exercise is appropriate for someone with an anxiety disorder. Three categories cause most of the trouble.
Rapid, cyclic hyperventilation (Wim Hof-style): These techniques deliberately drop CO2 and raise adrenaline. For a nervous system already primed to read low CO2 as a suffocation alarm, that can trigger panic symptoms directly. Some people with anxiety cannot do Wim Hof at all without triggering panic. That is a contraindication for the technique, not a personal failure.
Extended breath holds: Holds create air hunger on purpose. Between anxiety episodes, that controlled air hunger is the training stimulus for CO2 tolerance and it is useful. During acute anxiety or a high-anxiety stretch, the same sensation can tip straight into panic. Holds are for calm days.
Holotropic and other intense breathwork: Fast, sustained, high-volume breathing produces a hyperventilation-like physiological state by design. It is generally contraindicated for anxiety disorders for exactly that reason.
The safe repertoire for an anxious nervous system is short: extended-exhale breathing, the physiological sigh, box breathing (the 4-4-4-4 hold is brief enough to be tolerable for most people), coherence breathing, and diaphragmatic breathing. The wider question of what is and isn't safe is covered in is breathwork safe.
What to Do Instead
Each mechanism has a specific correction. None of them require you to push through discomfort.
Cut the session length first. If ten minutes feels like too much, do two. A two-minute session you complete calmly builds more tolerance than a ten-minute session you abandon in distress. Session length is the easiest variable to move and the one people move last.
Move your attention outward. If watching your body is the trigger, don't watch your body. Keep your eyes open and fix them on something specific in the room. Count out loud. Tap a finger on each count. The point is to keep the pacing without the interoceptive focus.
Extend the exhale, gently. Start at inhale 4, exhale 6 rather than inhale 4, exhale 8. The mechanism is the same — a prolonged exhale engages the vagal brake and heart rate slows — and the shorter ratio is easier to sustain without air hunger.
Use the physiological sigh when you need something immediately. A normal inhale through the nose, a short second sniff to top off, then a long slow exhale through the mouth. Balban et al. (Stanford, 2023) found this produced faster acute anxiety reduction than any other technique tested. Two or three repetitions is the whole intervention, which makes it the lowest-commitment place to start.
Leave the holds out entirely for now. No breath holds during acute anxiety, and none at all until the basic extended-exhale practice feels neutral rather than threatening.
Rebuilding the Practice So It Doesn't Backfire
The sensitivity typically reduces with practice, which is the encouraging part — but only if the practice stays inside your tolerance. Building it back looks like this:
Start below the level that triggered it. Two to three minutes, extended exhale at 4-in / 6-out, eyes open with external focus. Once per day.
Extend duration before intensity. Add a minute at a time until you can sit for ten minutes comfortably. Do not add new techniques while you are still extending duration.
Add coherence breathing once duration is stable. At around 5.5 breaths per minute it is slow, even and undemanding, with no holds and no forcing — which makes it the natural next step rather than a new challenge.
Add CO2 tolerance work last, and only between anxious periods. Gentle reduced breathing and BOLT score measurement belong in a settled week, not a bad one.
Judge progress on the trend, not the day. Some days will feel worse for reasons that have nothing to do with breathing. One bad session is not evidence that the practice is wrong for you.
If the practice keeps backfiring even at two minutes with external focus, that is worth naming rather than pushing through — see below.
When It Isn't the Breathing
Sometimes the backfire is a signal about something other than technique.
If breathwork consistently triggers anxiety even with a gradual approach, discuss it with a therapist who can work on the somatic anxiety component directly. Breathwork is a physiological intervention, not a treatment, and it is not the right first tool for everyone.
If what you're describing is a full panic attack rather than rising anxiety, the response during the attack is different from anything on this page — breathwork for panic attacks covers what actually helps while one is underway.
And if you are managing a diagnosed anxiety disorder: CBT is the evidence-based standard, prescribed medication is managed by your prescriber and nobody else, and breathwork sits alongside both rather than in place of either. Tell your therapist you're practising. Many anxiety therapists already use controlled breathing in treatment and can pace it appropriately for your anxiety level.
How Inhale Helps
Inhale's anxiety-focused sessions are built from the safe repertoire — extended-exhale, coherence breathing, box breathing — and nothing that drops CO2 rapidly. Sessions can be run as short as you need, and time-of-day recommendations keep activating techniques out of an evening. If you have been avoiding breathwork because it made you feel worse, the useful part is that the practice can be built back from two minutes upward, with the BOLT score trend showing the underlying CO2 tolerance changing even on days when nothing feels different.
Frequently Asked Questions
Can breathing exercises make anxiety worse?
Yes, for some people. The three usual causes are anxiety sensitivity (attention to bodily sensations amplifies them), the instinct to take a big forced inhale (which activates the sympathetic branch and can drop CO2 further), and techniques that are wrong for an anxious nervous system — rapid hyperventilation-style breathing and extended breath holds. All three have specific corrections, and none of them mean breathwork can't work for you.
Why does deep breathing make my anxiety worse?
Because "deep" usually means a big forced inhale. That activates the sympathetic branch rather than calming it, and if the exhale isn't extended to match, you move more air and lose more CO2 — producing dizziness, tingling and chest tightness that are easy to read as danger. The fix is to stop making the inhale bigger and start making the exhale longer.
Why do I feel more anxious when I focus on my breathing?
This is anxiety sensitivity. Attending closely to a physical sensation amplifies it, so the noticing itself becomes the trigger. Use external focus instead: keep your eyes open and fixed on something, count out loud, or tap a finger on each count. Cut sessions to two or three minutes. The sensitivity typically reduces with practice.
Which breathing techniques should I avoid if I have anxiety?
Rapid cyclic hyperventilation (Wim Hof-style), extended breath holds during anxious periods, and holotropic or other intense breathwork. The safe repertoire is extended-exhale breathing, the physiological sigh, box breathing, coherence breathing and diaphragmatic breathing.
Is it normal to panic during a breathing exercise?
It happens, and it happens more often to people with high anxiety sensitivity or a history of panic. It is not a sign that you are doing it wrong or that breathwork isn't for you. Stop the session, let your breathing return to normal on its own, and restart another day at a shorter length with external focus and a gentler exhale ratio.
Should I keep going if breathing exercises make me anxious?
Not by pushing through. Go below the level that triggered it — two minutes, 4-in / 6-out, eyes open — and extend from there. If it keeps happening even at that level, that is worth raising with a therapist who can address the somatic anxiety component rather than something to force.
