Breathwork Retreats: Slow vs Fast Breathing, the Tingling, and Who Should Skip Them

A breathwork retreat is a wellness stay built around deliberate breathing practice, and the single most useful thing to know before booking is that “breathwork” covers two very different things: slow breathing that calms you down, and fast, intense breathing that can leave you tingling, dizzy and sometimes in tears. Breathwork has moved from the edge of yoga timetables to the headline of whole retreats in the last few years, often sold with big promises about trauma, energy and transformation. Some of it is useful and well grounded. Some of it is a strong physical effect with a story attached. Here is how to tell which you are booking.

The two kinds of breathwork

Slow breathwork means breathing more slowly and gently than usual, and fast breathwork means breathing faster or more forcefully than your body needs, often for long stretches. They are close to opposites in what they do.

Slow breathing is the familiar kind: counted breaths, longer out-breaths, steady belly breathing. The NHS recommends a simple version for stress, breathing in gently for a count of five and out for five, for at least five minutes, ideally as part of a daily routine ¹. It is the breathing you meet in most yoga retreats and in the settling-in part of meditation and silent retreats.

Fast breathwork includes rapid, connected breathing with no pause between breaths, rounds of forceful breathing followed by breath holds, and long sessions lying down with loud music and a facilitator walking the room. These sessions can last an hour or more. They are the ones that produce the dramatic testimonials, and the ones that need more care.

What the evidence says

There is reasonable evidence that breathwork can reduce stress a little, and much less evidence for the bigger claims. A 2023 meta-analysis in Scientific Reports pooled randomised controlled trials and found breathwork was associated with lower stress than control conditions across 12 trials and 785 adults, a small to medium effect, with lower anxiety and depression scores in other trials too ².

The same authors were careful about the limits. They rated the overall risk of bias as moderate, found the effects were not significant in groups with diagnosed physical or mental health conditions, and found too few studies of fast-paced breathing to say much about it on its own. They called for more research on the safety of fast breathwork in particular, and warned of a miscalibration between hype and evidence ². That phrase is a fair summary of the retreat market.

So the honest version is that slow breathing is a cheap, decent tool for stress, in the same family as the meditation that Mayo Clinic describes as a simple way to reduce stress ³. Claims that a weekend of intense breathing will release trauma, reset your nervous system or detox your cells go well beyond anything the trials show.

The tingling, the dizziness and why it happens

The tingling hands, light head and clawed fingers people describe in fast breathwork are the recognised effects of over-breathing, not energy moving. Breathing faster or deeper than you need blows off carbon dioxide, and low carbon dioxide in the blood narrows blood vessels, including those to the brain. Cleveland Clinic lists numbness and tingling in the arms or around the mouth, feeling light-headed or dizzy, and muscle spasms in the hands and feet among the symptoms of hyperventilation ⁴.

I learned this the slightly embarrassing way. At my first fast breathwork session, at a yoga retreat a few years into my retreat habit, my hands curled up and went numb about twenty minutes in, and the facilitator told the room this was “stuck energy releasing”. It was very convincing at the time. It was also, I later learned from Ingrid with some amusement, a textbook description of over-breathing. It went away within minutes of breathing normally, which is what usually happens.

That does not make the experience worthless. Many people find fast sessions intense and cathartic, and some find them genuinely helpful. But understanding the mechanism matters, because it changes how you judge a facilitator who tells you to push through it. Cleveland Clinic also notes that rapid breathing for the first time, outside a situation like this, can signal a medical problem and needs prompt advice ⁴.

Who should be careful

Talk to your own doctor before trying fast or intense breathwork if you are pregnant, or have a heart condition, high blood pressure, epilepsy, a history of fainting, or a mental health condition. These are the kinds of conditions a careful retreat asks about, and a good one will ask before you arrive. Fast sessions can bring up strong emotions, and for someone with a history of panic attacks, trauma or psychosis, a crowded room with loud music and a facilitator urging you on is not a neutral setting.

The safety rule that matters most is simple: never practise fast breathing or breath holds in or near water, in the bath, while driving, or standing somewhere you could fall. Over-breathing before a breath hold delays the urge to breathe, so oxygen can fall far enough to make you black out before you feel you need air; the US CDC has linked this to drownings ⁵. Be particularly wary of any programme that pairs intense breathing directly with an ice bath or cold plunge; the cautions on cold water in saunas and cold plunge apply twice over.

If you are managing any health condition, the general advice in wellness retreats with a health condition applies here too: declare it, ask who reads the form, and do not let a retreat tell you to stop prescribed treatment.

Choosing a breathwork retreat

Ask which style of breathwork the retreat uses, how long the sessions are, who leads them and what training they have, and what happens if someone feels unwell. A decent answer names the technique, gives a session length, mentions a health questionnaire, and says plainly that you can slow down or stop at any time without being pressured.

Then check for the familiar warning signs in red flags when choosing a wellness retreat: promises of cures, talk of releasing toxins through the breath, facilitators whose training no one can name, and pressure to buy follow-up courses or supplements. Wellness tourism is a huge and largely unregulated market ⁶, and breathwork facilitator training varies widely, so ask what it involved.

A good sign is a retreat that teaches both kinds, explains the difference, and sends you home with a slow breathing routine you can actually use. That is the part with the best evidence and the longest shelf life.

What to take home

The most useful thing a breathwork retreat can give you is a short, slow breathing practice you will actually do, not a peak experience. The NHS exercise takes five minutes ¹. Done at the end of the working day or in bed, it pairs well with the habits in sleep retreats. If the intense sessions helped you, keep them for supervised settings. If they did not, you have lost nothing by sticking with the slow kind.

General information, not medical advice. A wellness retreat is not medical treatment and does not replace your own doctor. Speak to your doctor before intense breathwork if you are pregnant or have a heart, blood pressure, seizure or mental health condition, and never practise breath holds or fast breathing in or near water.
