Breathwork session left my hands numb and curled up, is that normal or did something go wrong

Did my first proper breathwork session tonight at a weekend retreat, the fast connected breathing kind, lying on a mat for about an hour with very loud music. About fifteen minutes in my hands started tingling, then went numb, then my fingers sort of curled in on themselves and I could not straighten them. My lips went tingly too. I was honestly frightened for a minute.

The facilitator came over and said it was "energy moving through" and to keep breathing through it. Which I did, and it passed after the session, but I am sitting here a bit shaky wondering if that was really fine or if I should have stopped.

There is another session tomorrow morning. Do I go?

Had exactly the claw hands the first time I did the fast breathing style. Spooky but it passed as soon as I slowed down. The thing I would say, because I have seen people do it, is NEVER do that kind of breathing and then hold your breath in the plunge or a pool. Some places run them back to back. I do my cold water separately now and only breathe normally in it.

I teach slow pranayama, which is almost the opposite of what you describe, and I am never sure "energy" is a helpful word for what happened to you. You are allowed to slow down or stop at any point in any session, whatever the facilitator says. A good one will tell you that at the start, not wait for you to ask.

What you describe is very common in fast breathwork and has a straightforward explanation, but you were right to ask, and you are always entitled to stop.

When you breathe faster or deeper than your body needs, you blow off carbon dioxide, and the level in your blood drops. That change is what produces the classic picture: tingling or numbness in the hands, arms and around the mouth, light-headedness, and sometimes spasm of the small muscles in the hands and feet, which is the curling you felt. It usually settles within minutes of returning to normal breathing. So "energy moving through" is a poetic description of a well-understood effect of over-breathing.

Whether you go tomorrow is your call, and a few things should shape it. If you have a heart condition, high blood pressure, epilepsy, a history of fainting, panic attacks or another mental health condition, or you are pregnant, intense breathwork is something to discuss with your own doctor first rather than decide on a retreat floor. If none of that applies, you might ask the facilitator whether you can breathe more slowly during the session, or simply ease off as soon as the tingling starts; nobody needs to reach the claw stage to get something out of it.

Two firm points. Neil is right: never combine fast breathing or breath holds with water, because a faint in a pool or plunge is a different order of risk; the cautions in saunas and cold plunge apply doubly when breathwork comes first. And if you ever get rapid breathing with tingling out of the blue, outside a session, or with chest pain, that needs medical advice rather than a forum.

If the calming side is what drew you in, the slow breathing taught in meditation and silent retreats is the end of the spectrum with the steadier evidence behind it.

Update in case it helps anyone. I went to the second session but told the facilitator first that I would be going slower, and she was completely fine with it. Breathed at maybe half the pace, got a bit of tingling and stopped there, and it was actually a much nicer experience. Lay there feeling very calm rather than terrified. Not sure I will do the full intensity version again but I would do that.

This thread is a big part of why I finally wrote up breathwork retreats, including the slow versus fast distinction Ingrid sets out here, and my own claw-hands moment at a yoga retreat a few years back, when I was told the same thing about energy. Rowan, the half pace approach is exactly what I would have done with hindsight.
