It's one of the first things people ask us, usually quietly, after class: is breathwork actually safe? It's a good question. Breathing feels like the most natural thing in the world, so it can be surprising to hear that some breathwork practices come with real cautions.
The honest answer: for most people, gentle breathwork is very safe. But some styles are intense on purpose. Fast breathing, long breath holds and big emotional releases change your body chemistry and your nervous system quickly. That's where knowing your own health, and working with a well-trained facilitator, really matters.
Is breathwork safe for most people?
Yes. Slow, steady practices like extended exhales, box breathing, alternate nostril breathing or simply noticing your natural breath are gentle and widely accessible. These are the practices we reach for when someone is anxious, depleted or new to this work.
The cautions mostly apply to activating practices: fast or connected breathing with no pause, forceful breathing, extended breath holds, and long sessions designed to create an altered state or a big release. These can be powerful and healing. They're also physically demanding, which is why they aren't the right fit for everyone, every day.
Who should be careful with breathwork?
If any of these apply to you, talk to your doctor before trying intense breathwork, and always tell your facilitator before a session:
Heart conditions, including cardiovascular disease or a history of heart attack or stroke
High blood pressure that isn't well controlled
Epilepsy or a history of seizures
A history of aneurysm
Pregnancy
Severe asthma, COPD or other significant breathing conditions (keep your inhaler nearby)
Recent surgery or injury, or anything you're still physically recovering from
Glaucoma or a history of retinal detachment
A history of psychosis or bipolar disorder, or a severe mental health condition you're currently navigating
Medications that affect your heart, blood pressure, blood sugar or mood
This list isn't complete, and it isn't meant to scare you. Many people with these conditions can still benefit from gentle, slow breathing. It just means the intense styles should wait, or be adapted, with your doctor in the loop. And never combine breathwork with alcohol or other substances.
What about trauma, anxiety and big emotions?
This is the part most breathwork marketing skips. Breath work can bring up a lot: tears, shaking, old memories, fear, grief. Sometimes that's exactly what someone needs. But if you're in an acute crisis, or you tend to dissociate or get overwhelmed easily, pushing into an intense session can leave you feeling more flooded, not more free.
Trauma-informed breathwork works with your nervous system, not against it. In practice that means:
You're always in charge. You can slow down, open your eyes, return to normal breathing or stop at any point. Nothing is "pushed through."
Staying within your window of tolerance. The goal is enough activation to create change, not so much that you shut down.
Regular check-ins during the session, not just at the end.
A clear landing. Time at the end to slow the breath, come back into the body and integrate what came up.
Choice in how you practice. Gentler options are offered alongside the intense ones.
If you live with anxiety, starting with slow, calming practices first is often the most supportive path. Our post on why breathwork isn't calming you down goes deeper on this.
What side effects are normal during breathwork?
During more active practices it's common to feel tingling in the hands, feet or face, light-headedness, tightness or cramping in the hands, changes in temperature, emotional waves, or yawning and shaking afterwards. Most of these come from shifts in carbon dioxide and pass within minutes of returning to normal breathing. We explain exactly why in why your hands tingle during breathwork.
Stop and return to normal breathing if you feel chest pain, a racing or irregular heartbeat, severe dizziness, or like you might faint, and get medical help if it doesn't settle quickly.
How to practice breathwork safely
Start gentle. Learn slow, regulating practices before activating ones.
Tell your facilitator about any health conditions, medications or pregnancy, every time.
Practice lying down or seated for intense styles. Never in water, while driving or anywhere a dizzy spell could hurt you.
Remember that less is often more. You don't need the biggest experience for breathwork to work.
Choose a facilitator trained in contraindications and trauma-informed practice, and don't be shy about asking how they were trained.
The bottom line
Breathwork is safe for most people when it's matched to the person. The same breath that settles one nervous system can overwhelm another, which is why we never teach one technique for everyone. At Holistic Breath Academy, our facilitators learn many ways to breathe from practices around the world, how to screen for contraindications, and how to hold space in a trauma-informed way, so every session meets people where they are.
