In May, I ran a company-wide session on breathwork and nervous system regulation at Sofina, an investment holding company based in Brussels. The brief was simple. They wanted something experiential, with tools they could use the same day — for the boardroom, the negotiation, the 2pm slump, the Sunday night when sleep won't come. What we did in nervous system regulation workshop Here's the frame I built the nervous system regulation session around: Nervous system regulation is your ability to match your internal state to what the present moment actually calls for. A board meeting calls for sharp and alert. A team lunch — relaxed, engaged. The drive home calls for proper winding-down. Most of us stay in the same gear regardless, usually hovering somewhere between wired and tired, never quite landing anywhere. So we started with the arousal continuum. From panic on one end, through stressed, alert, calm, drowsy, all the way to freeze on the other. The question for the room: where do you spend most of your day? And — separately — where do you wish you spent it? Then the breath. Because it's the most direct lever we have on this continuum, and one of the only things in our physiology that runs...

In April, I spent a morning with the team at Data Tech Fund — a VC firm whose people are spread across the world and come together once a year for their annual offsite. They'd been in cognitively demanding work for a few days. Vision, strategy, big-picture thinking. By the time I arrived, what they needed was the opposite of that: less thinking, more body. What we did in this annual offsite breathwork workshop This was a purely experiential, somatic breathwork session. No slides. Just an hour of slowing down and exploring what a healthy, functional breathing pattern actually feels like, and why it matters for everything from brain function to recovery to sleep. The concept I most wanted them to walk away with was interoception—your brain's ability to sense what's happening inside your body. Heart rate, breath, muscle tension, gut activity. It's a skill that's massively undervalued, especially by highly cognitive, analytical people. And it's increasingly backed by research as one of the most important capacities you can train for self-regulation, decision-making, and emotional resilience. We spent more than an hour with our eyes closed, just feeling into the breath, the nervous system, and the sensory systems. One person was genuinely surprised it had...
