Nervous System Reset

Five, seven or ten days at Insda for a body that has been on alert for years. TRE every day, breathwork that brings you down rather than up, sauna and cold, a sleep protocol, bodywork, and a heart-rate reading on the day you arrive and the day you leave so the change is measured, not described. First cohort opens Sunday 28 February 2027.

Retreat highlights

  • A heart-rate variability reading on arrival and on departure, and a short stress questionnaire with it, so you leave with a number that moved
  • TRE every morning, tension and trauma release, taught so the practice stays yours
  • Breathwork that lengthens the exhale and slows the heart, never the kind that gets you high
  • Cold immersion, every afternoon, with the timings set for you
  • A sleep protocol from the first night: lights, hours, no screens, no caffeine, no alcohol for the stay
  • Bodywork through the stay: two sessions on five days, three on seven, five on ten
  • One-to-ones with a trauma-informed practitioner: two on the seven-day, four on the ten
  • A longer intake on the ten-day, read before a place is confirmed
  • A thirty-day plan on the seven, sixty on the ten, and the calls to keep it
  • Ten places, eight on the ten-day, phones away, both airport transfers

About this retreat

You are not in crisis. You are not at peace either.

You sleep and wake tired, you know the words for what is happening to your nervous system, and knowing has not changed it. You have tried the app, the cold showers and a holiday, and the holiday worked for about a week.

This stay is built for that gap. Five to ten days in the hills above Hang Dong doing the things that actually move a nervous system out of alert, every day, in order, with somebody watching: release through the body, breath that slows the heart, heat and cold, sleep, food that does not fight you, and nothing to organise. Nobody will ask you to talk about why. The body already knows.

We measure it. Heart-rate variability on the morning you arrive and the morning you leave, with a short questionnaire alongside. You take the numbers home, and the plan to keep them moving.

Every place is offered after a call. On the ten-day, the longer intake is read before we confirm. If this is not the right stay for where you are, we will say so on the call.

Three lengths, one protocol

Every cohort opens on a Sunday and runs the same days. The five-day leaves on the Thursday, the seven-day on the Saturday, and the ten-day stays three more nights.

Sun 28 Feb to Thu 4 Mar

Five days, four nights

The reset: the baseline reading, four days of the full protocol, the sleep rules, two bodywork sessions, the departure reading. Enough to feel the floor come back under you.

Sun 28 Feb to Sat 6 Mar

Seven days, six nights

The reset plus the settling: two one-to-ones, a half day of silence, a third bodywork session, a thirty-day plan and a call a month later.

Sun 28 Feb to Tue 9 Mar

Ten days, nine nights

The long format: the longer intake, four one-to-ones, two silent days, five bodywork sessions, three readings, a sixty-day plan and two calls after.

The shape is fixed. The timing moves with the group.

Who this is for

  • You have been running hot for years and stopped noticing until something gave
  • You wake at four and lie there
  • You know the words, polyvagal, cortisol, window of tolerance, and none of them has helped
  • You have had a burnout, or you can see one coming
  • You want something that works on the body without a story attached

Who it is not for

  • You are in acute crisis or recently out of hospital, which needs a clinician first and we will say so on the call
  • You are pregnant or managing a heart condition without your doctor's clearance, because the cold and the sauna are daily
  • You want a spa week. This is a protocol, with a pool

This programme is not medical treatment and does not replace care from your own doctor. It is not offered as a treatment for any disease or condition.

Accommodation

Shared teak rooms, two to a room, same gender unless you book together, your own bathroom and a balcony on the garden. A room to yourself adds US$60 a night. The sleep protocol means early nights and blackout, and the rooms are set up for it.

Venue and amenities

Insda Wellness Resort sits on the Hang Dong to Samoeng road, twenty-three kilometres out of Chiang Mai and far enough into the hills that your phone stops mattering. Twenty-nine teak rooms, gardens, a pool, and a long open hall where the circles are held. You are met at the airport and driven in, and you do not leave until it is done.

Chiang Mai International Airport (CNX), then twenty-three kilometres south west to Hang Dong and up the Samoeng road. About forty-five minutes, longer in rain.

Do not book flights until your place is confirmed. Every place is offered after a call, and once it is confirmed you get every logistical detail in writing.

You are met at arrivals on day one and driven straight to the resort. On the last day you are driven back with time to spare. If you are flying long haul, arrive the night before and sleep in the city.

Questions people actually ask

Do I have to do the cold?

Yes, and it starts at thirty seconds. Nobody is thrown in. The time goes up through the week.

What is TRE?

A set of simple exercises that let the body shake off what it has been holding. Everybody has the reflex. Most people have never let it run.

Is there any talking therapy?

The one-to-ones on the seven and ten-day are with a trauma-informed practitioner and you can use them to talk. The protocol itself works on the body.

What do the numbers mean?

Heart-rate variability is the simplest honest measure of how much room your nervous system has. Higher is better. You get yours in writing, before and after, with a plain explanation.

Can I keep my phone?

No. It goes in the office on day one and you can check it at a set time each day if you need to.

What happens after?

The plan, the calls, and the Henosis community. The Kundalini class on Tuesdays in Chiang Mai is there if you stay in town.
