Your body is still on alert, even when you finally lie down to sleep.
One week for your nervous system to lower its guard again.
Essencia Nervous System Renewal™ is the intensive medical experience in Nicoya for those who live at full speed, sleep poorly and can't seem to switch off — with NESA neuromodulation, personalized IV therapy and medical accompaniment.
This program is for you
You sleep, but you don't rest. You live with the engine running and can't find the off switch. You've tried sleeping more, meditating, unplugging on weekends — and within days you're back at the same point. It's not a lack of willpower: it's your nervous system trapped in alert mode.
Check what you recognize in yourself:
If you identified with the stress or the insomnia, plus at least one more point, this program was designed with you in mind.
From one of the world's Blue Zones.
Our clinic is on the Nicoya Peninsula, Costa Rica — one of five places on the planet where people live longer and healthier lives.
This is not a retreat or a spa: it's a medical program with clinical direction, designed to give your nervous system a deep reset and the tools to sustain it once you're back in your life.
There are no generic protocols: there is only yours.
What your program aims to work on with you
Sleeping deeply and waking up feeling truly rested.
Slowing your internal pace — living without the engine always on.
Responding to stress from calm, not from reaction.
Regaining mental clarity and focus.
Leaving with tools to sustain calm in your daily life.
Individual results vary from case to case. This section describes the program's goal, not a guaranteed outcome.
Your process, step by step
A program of about two and a half months, with an intensive week at its core:
-
Prior medical evaluation (virtual)
Before you travel, the doctor evaluates your case and confirms the program is right for you. Your week arrives designed, not improvised.
-
Intensive week in Nicoya
NESA neuromodulation sessions, personalized IV therapy, your Essencia Scan functional evaluation, individual breathwork and sound healing sessions, and your nutrition plan.
-
Medical follow-up (2 months)
Two virtual consultations to sustain your results in daily life, plus close accompaniment via WhatsApp.
-
Your plan going forward
At the close, you and the doctor define how to continue your process beyond the program.
Your clinical team
Dr. Ana Laura Rodríguez Rojas, Medical Director of Essencia Azul Health & Longevity Clinic, with a focus on functional medicine, neurometabolic health and longevity science.
Your program is designed and supervised under her medical direction, with a clinical team dedicated to your case — from the prior evaluation to follow-up. Not a template, not a catalog experience.
One in-person week, with support before and after
The evaluation and follow-up are virtual, from wherever you are. The intensive phase is in person at our clinic in Nicoya, on dates we coordinate with you in advance.
Before you start
Is this a wellness retreat?
No. It's a medical program: it starts with a medical evaluation, has an individualized protocol and continues with two months of clinical follow-up. The setting is beautiful; the structure is medical.
How long does it last?
About two and a half months: a prior evaluation, an intensive in-person week in Nicoya, and two months of virtual follow-up. Your week's dates are coordinated with you.
Do I have to travel to Costa Rica?
Yes, the intensive phase is in person in Nicoya. The evaluation and follow-up are virtual, from wherever you are.
What is NESA neuromodulation?
A non-invasive technology, with no needles, that applies imperceptible microcurrents to support the regulation of your autonomic nervous system. It's the central tool of your intensive week.
How do I start?
By booking your evaluation with our team — it's the first step, before organizing your trip.
Medical notice: neuromodulation and supportive therapies
This protocol requires a prior medical evaluation and is applied at the physician's individual discretion. Non-invasive neuromodulation and supportive IV therapies have contraindications that must be ruled out before starting. Results may vary from person to person. This program is designed to support the regulation of the autonomic nervous system and does not replace conventional medical care, psychiatric treatment or psychological support; nor should any medication be discontinued without instruction from your treating physician.
Give your nervous system the reset it's been needing.
