What you want more of
Deep, restorative sleep
Fewer nights spent staring at the ceiling, and more mornings that feel like a real beginning.
Does this sound like you?
- 01
You can afford any mattress on earth — so why are you still awake at 3 a.m., running tomorrow's meeting on a loop?
- 02
You've optimized everything else in your life. Why is the one thing your body should do for free the thing you can't get right?
- 03
Your wearable keeps telling you your sleep is broken. Is there anyone who can tell you why?

How many of this year's biggest decisions were made by a version of you that hadn't truly slept in weeks?
(001) What's really going on
For a lot of the people we built this for, the problem isn't that they don't know sleep matters. It's that a busy, high-pressure life keeps the nervous system switched on long after the lights go off, so the body never fully drops into deep rest. Add years of bright screens at night, dim days indoors, and a wandering schedule, and the internal clock quietly loses its rhythm. Poor sleep usually isn't a willpower failure. It's a body that has forgotten how to let go, in an environment that keeps asking it to stay alert.
(002) What the evidence says
Every claim links to a primary or authoritative source.
Adults generally do best on seven or more hours of sleep a night, and steady, sufficient sleep is tied to lower risk of heart disease, type 2 diabetes, high blood pressure, and stroke.
Centers for Disease Control and Prevention (CDC)In a study of over 25,000 U.S. adults followed for about a decade, both too-little and too-much sleep raised the risk of dying, with the lowest all-cause and cardiovascular mortality clustered around seven hours a night.
Frontiers in Public Health (peer-reviewed cohort study, NHANES)Deep, slow-wave sleep is when the brain's glymphatic system does much of its overnight housekeeping, helping clear waste proteins such as amyloid-beta, and this deep sleep naturally thins as we age.
University of Washington Memory and Brain Wellness CenterFor long-term insomnia, leading physicians recommend cognitive behavioral therapy for insomnia (CBT-I), a skills-based approach to rest, as the first-line treatment ahead of sleeping pills, with fewer harms.
American College of PhysiciansGetting outdoor morning light helps reset the body's internal clock and support natural melatonin timing, and more morning sun exposure was linked to better overall sleep quality.

Santerra is not a medical facility and does not diagnose or treat disease. The week is built to move the inputs your own physician measures.
(003) The mechanisms your week is built on
Each of these sits behind a specific slot on your itinerary, grouped by how strong the evidence is. Where the honest answer is we think so, and we are measuring it, the page says so rather than dressing it up.

“Rest isn't something you force. It's something the body remembers how to do, once you give it the right nights.”
(004) How Santerra drives it
The method, aimed at this
Three phases. Most programs run only the middle one.
[PHASE 1]
Preparation
Before you arrive, our flourishing assessment and your wearable give us a real baseline of how you're actually sleeping, not how you think you are. You set one honest intention for rest, so the whole week has a target. This is also where the root-cause work starts: naming the habits and pressures that have been keeping your system switched on at night.
[PHASE 2]
Immersion
Across five nights at Santerra you live the science instead of reading it. Days start with morning light and time outdoors to reset your clock; workshops teach the same skills-based, CBT-I-style tools clinicians use instead of pills. A full rest day, plus forgiveness and purpose inner work, quiets the mental churn that keeps so many people awake, so the body can finally drop into deep sleep.
[PHASE 3]
Reinforcement
New sleep isn't built in five nights, it's protected over ninety days. Group coaching with your cohort and a small community help you hold the rhythm at home, through travel and stress. Then at day 90 we re-measure, so the change shows up as data, not just a nice memory of your week.
(005) Why we suggest what we suggest
Four of the afternoon choices earn their place on this track in particular. These are what your own day-sheets actually schedule — a nudge, never a default.
Stargazing
The wind-down that replaces the screen — and the reason the evening is shaped the way it is.
Gooley et al., J. Clinical Endocrinology & Metabolism, 2011A second guided hike
Daylight is the strongest input to the clock you came here to reset, and the second hike is the easiest way to get more of it.

Your day-sheet plays it properly scored. Regular social timing is itself a clock input, and this is the pleasant version of it.
Oja et al., British J. Sports Medicine, 2017Desert amphitheatre
Somewhere to spend the last hour of the evening that is not a screen and not your room.
Piff et al., J. Personality & Social Psychology, 2015
(006) And then we measure it
At day 90 we re-run your flourishing assessment, watching especially the health and mental-wellbeing domains, alongside your wearable's sleep data, so we can see the change in deep-sleep minutes, sleep consistency, and resting heart rate rather than just asking how you feel.
Day ninety is the one that counts — anyone can feel better on the drive home. You leave with your results in a form you can share with your own physician.
