Nervous System Reset · HAVN · Swedish Lapland

Your typical day

How a day in the cabin actually looks.

Day 1 is the baseline. Day 2 the rhythm forms. Day 3+ the protocol compounds.

Morning · 6:30–10:30am

6:30am Wake. Protocol card on your bedside table tells you what's next. No decisions.

7:00am HRV session. 14 minutes. Polar H10 chest strap + tablet. Watch your heart rate variability shift in real time. Finds your resonance frequency on Day 1.

8:00am Cold dip. 2 min Day 1, building to 4 min by Day 3. Tank at 4–8°C. Norepinephrine spikes. Your nervous system fully activates.

8:20am Sauna. 80–100°C, 15–20 min. Parasympathetic rebound. This is the strongest natural recovery signal your nervous system receives.

10:00am Nature walk. Marked trail into boreal forest. 30–60 minutes, slow and sensory. Cortisol continues dropping. No phone.

Afternoon · 12:00–5:00pm

12:00pm Lunch. Light, within your 10-hour eating window. Circadian timed.

1:00pm tVNS session. 60 minutes. Clip the Neurosym device to your ear. Rest, read, nap. The device works. You don't have to.

3:00pm Free time. Forest, water, writing, a second cold/sauna cycle if you want one.

4:30pm Breathwork. 20 minutes. Extended exhale protocol, audio-guided. Day 2+ progresses to CO₂ tolerance and breath holds.

Evening · 7:00–10:00pm

7:00pm Dinner. Light, within your eating window. Last meal before the sleep window opens.

8:00pm Evening tVNS session. 60 minutes. Red-spectrum lamp on. Blue-light glasses for any screens.

9:30pm Sleep prep. connect-to-self meditation, 15 minutes. Guided audio.

10:00pm Sleep. Under-mattress sensor activates. O₂ ring on finger. The data appears on your tablet in the morning.

The protocol card on your bedside table shows your exact schedule each day. It adjusts progressively. Day 2 and 3 build on Day 1 with longer cold exposure and deeper breathwork.

Who comes to HAVN

Always on. Rest that fails.

Holidays feel restless. Weekends pass without recovery. You wake from sleep still tired.

Tired but wired.

Exhausted by evening, alert at 3am. The gap between performance and recovery is widening.

Stuck. Not shifting.

You've tried things. Or you haven't had the space to start. Either way, your system isn't moving on its own.

Why the usual solutions don't work

Two systems.
One is stuck on.

Sympathetic, fight or flight

Parasympathetic. rest and repair

The nervous system is not a fixed trait. it is elastic. The HAVN programme trains that elasticity: deliberate cycles of full activation and genuine recovery, repeated daily, measured throughout. The practices are well-researched. The missing piece has always been the environment to do them in.

Why this is different from anything you've tried

See the peer-reviewed research →

This is for you if

You want the protocol and the environment, without a group, a facilitator, or fixed cohort dates
You're tired of performing all the time and never being able to actually enjoy your downtime or recover
You're self-directed. You can follow a structured protocol without external accountability.
Your schedule makes fixed cohort dates impossible. You need the flexibility to book on your terms.
You want data: HRV measurements, sleep architecture, a before/after you can point to
You're coming solo, with a partner, or with a friend. Not looking for a group experience.

Most self-guided guests are founders or executives in their mid-30s to late-40s. Many have done biohacking, cold exposure, or breathwork before. They arrive with the discipline to follow a protocol. they're looking for the right environment to do it in.

This is not for you if

You're looking for a passive spa holiday
You want or need a facilitator guiding each session. Consider the facilitated cohort →
You have a clinical mental health diagnosis requiring medical supervision

Not sure if self-guided is right for you?

What's waiting in your cabin

Everything you need.
Nothing to figure out.

You watch a 15-minute orientation video on arrival. After that, the protocol card on your bedside table tells you what to do each morning. The devices do the rest.

Lapland in summer already gives you 20+ hours of natural daylight. the strongest circadian signal possible. The clinical lamp is used in the evening wind-down protocol instead: red-spectrum light after 9pm to begin melatonin onset. Blue-light blocking glasses also included for screens in the evening.

A small Neurosym device that clips to your ear and directly activates your parasympathetic nervous system. 60 minutes morning, 60 minutes afternoon. You rest, read, or eat while it works. For many guests, this is the deepest rest they've experienced in years.

Chest strap paired with the cabin tablet. Two guided sessions daily. you watch your heart rate variability shift in real time. Finds your personal resonance frequency on Day 1. Your final session repeats Day 1 exactly. the before/after is the most significant data point of the stay.

Under-mattress Withings sensor tracks sleep stages and respiratory rate. Finger O₂ ring monitors overnight oxygen. You just sleep. the data appears on your tablet each morning. Deep sleep, REM cycles, any disturbances. Most guests see measurable improvement by night 2.

Finnish sauna reaching 80–100°C with protocol cards specifying temperature and timing. Cold dip in natural Lapland water. The deliberate cold-to-sauna sequence is the most powerful tool for retraining nervous system elasticity. Cold creates the sympathetic peak, sauna creates the deepest parasympathetic recovery.

Resonance frequency pacer, activation breathing guide, extended exhale protocol, connect-to-self meditation, binaural beats for sleep. All pre-loaded on the cabin tablet. no WiFi needed. The protocol card tells you which guide to use each morning and evening.

Marked trails from the property directly into genuine boreal forest. Shinrin-yoku (forest bathing). the Japanese practice of immersive time in nature. has 60+ peer-reviewed studies showing 12–21% cortisol reduction from 20 minutes of forest exposure. Not a walk for exercise. A slow, sensory immersion in birch and pine. The daily nature protocol is on your protocol card. Most guests describe this as the quietest hour of the day.

A morning qigong sequence in the cabin (15 minutes, video-guided on your tablet). Marked trail running and walking routes through the forest. Outdoor paddle court for paddle sessions. Bodyweight workout space and yoga mats available. Movement is optional but encouraged: it amplifies the protocol's effects on HRV and sleep. You decide when, how, and how much.

Authentic relating card deck with evening connection games and vulnerability exercises. Co-regulation through genuine contact with your partner activates the same parasympathetic pathways as facilitated group work, same mechanism, different format.

The daily structure. Protocol card tells you what to do each morning and evening.

The question we built the answer to

"What happens
when I go home?"

Your personal daily protocolBreathing rate, sleep timing, morning rhythm, built from your data, for your life.

Your HRV dataEvidence of what shifted. A number, not a feeling you'll question later.

Why this exists

"We've hosted hundreds of guests and kept seeing the same pattern. The environment helped, but it wasn't enough. The protocol had to come with it. So we built it."

From people who've stayed

"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."

Maximilian · Munich

Founder, 41

"I didn't expect the cabin itself to do anything. But stepping out at 6am with nothing but forest and cold air. something shifts before you've even done anything from the protocol."

A.K. · Stockholm

Guest, Lapland cabin stay

"My deep sleep went from 45 minutes on night 1 to 1 hour 52 minutes by night 3. I haven't slept like that in years."
