What is breathwork, and what happens in a session?

What is breathwork, and what happens in a session?

Breathwork covers a range of breathing patterns, each with its own effect on the body. The heart of my practice is connected breathing: deeper and faster than everyday breathing, with no pause between the inhale and the exhale. Kept going for a stretch of time, that rhythm changes the body's chemistry and lets the nervous system drop out of alert mode. A session runs about ninety minutes: we talk briefly, then you settle in, sitting or lying down, and breathe to music while I guide the pace. We close slowly and leave time to land before you head back into your day.

Who shouldn't do breathwork?

Who shouldn't do breathwork?

Breathwork is safe for most people, but not for everyone. Check with your doctor first if you are pregnant, or have ever had epilepsy or seizures, psychosis, or a cardiovascular condition such as high or low blood pressure, heart disease, or stroke. Not sure if something counts? Bring it up on the intro call and we'll look at it together.

Do I need any experience?

Do I need any experience?

None. Most people arrive having never tried it. The breath does the work; you just have to show up.

How intense is it? Will it be too much for me?

How intense is it? Will it be too much for me?

This is your practice, and you stay in charge of it the whole way through. I'll guide you and encourage you to lean in, it's called breathwork for a reason, but if something feels like too much or you'd rather take it easy, you simply soften the breath. The depth is always in your hands.

Will I feel something? What if nothing happens?

Will I feel something? What if nothing happens?

There's nothing you're supposed to feel. The breath can carry you somewhere deep one time and simply leave you calm the next, and now and then very little stirs at all. Every one of those sessions counts the same.

What should I wear, and should I eat beforehand?

What should I wear, and should I eat beforehand?

Loose, comfortable clothes you can move and rest in. Eat light beforehand, a snack a couple of hours ahead is better than arriving full, and skip the caffeine that day if you can. Coffee especially; tea is fine.

Where do sessions happen? Can I do it online?

Where do sessions happen? Can I do it online?

In person only, mostly in Amsterdam. As much as I'd love to reach everyone, through a screen I can't look after you the way this work asks me to, and your safety and support come before everything else. So for now, we breathe in the same room.

What's the free intro call, and am I committing to anything?

What's the free intro call, and am I committing to anything?

It's twenty minutes, by phone or video, whichever suits you. We talk about what's going on for you, I answer your questions, and if it doesn't feel like a fit, that's a perfectly good outcome too.

Can I come with a partner, or do I have to come alone?

Can I come with a partner, or do I have to come alone?

Coming on your own is actually the best way in, with no one familiar beside you, it's easier to surrender fully to the practice. That said, you're welcome to bring a partner or a friend, and for breathing as a pair there's partner breathing, where you can also come solo and be matched with someone. From time to time I run group partner breathing sessions as well.
