Who comes to HAVN
01
Always on. Rest that fails.
Holidays feel restless. Weekends pass without recovery. You wake from sleep still tired.
02
Tired but wired.
Exhausted by evening, alert at 3am. The gap between performance and recovery is widening.
03
You've tried everything.
Cold, breathwork, therapy, biohacking. A 5 out of 10. Nothing sticks past the first week home.
Why the usual solutions don't work
Two systems.
One is stuck on.
Sympathetic, fight or flight
The activation system

Cortisol spikes. Deep sleep blocked. Designed for short-term threats. Devastating when it never switches off.

Parasympathetic, rest and repair
The recovery system

HRV rises. Deep sleep enables brain clearance. The system that makes sustained performance possible.

The nervous system is trainable. HAVN trains the range, full activation, genuine recovery, through deliberate cycles, measured throughout.

This is for you if
  • Founder, executive, or senior professional operating at 60–70% of your potential
  • You want data: HRV, sleep architecture, a before/after you can point to
  • You've tried the standard interventions. They weren't enough.
  • You can take 3 or 7 days away, no calls, no laptop
  • You're willing to be uncomfortable: cold water, honest circles, vulnerability
This is not for you if
  • You're looking for a wellness holiday or passive recovery experience
  • You have a clinical mental health diagnosis requiring medical supervision
  • You will check email or take calls during the retreat, closed container, no exceptions
  • You are not willing to enter cold water
  • You want the result without the process

Why this exists
Eugene Pienaar
Co-founder · HAVN
"I spent years trying everything. Still a 5 out of 10. The problem wasn't the practice, it was the environment."

The protocols are well-researched. Cold water raises dopamine 250%, nobody had combined these tools into one sequenced programme in a place built for the work. Read the research →

The facilitation team Every HAVN cohort is co-facilitated by a certified space holder trained in authentic relating and a nervous system specialist with HRV biofeedback certification, both trauma-informed, both with a minimum of 10 years of experience with high-performance groups.
From the people who applied
"I've done breathwork retreats before. Nothing stuck past the first week home. I want something with actual measurement, a before and after I can point to."
