A wearable for your nervous system

Anasa

Scroll

Anasa is a wearable that senses the shifts in your breathing and heart rhythm that come with stress, and responds with a gentle haptic rhythm to help you regulate — steadying your nervous system in the moments that matter, before a reaction takes over.

Minimal by design.
Timeless by nature.

What lives on the outside is jewelry. What lives on the inside is science. Built to look like jewelry, not a wellness gadget — quiet, sophisticated, easy to wear every day. The regulation stays invisible. Only you know it's there.

Why It Matters

You can do everything right
and still lose the moment.

You can sleep well, train, eat clean, take your health seriously — and still lose the moment to a reaction you didn't choose. That's not a discipline problem.

Your body responds to stress before your mind has named what's happening. By the time you feel the emotion, the physical reaction is already underway. Emotions are the brain's way of labeling what's happening in the body — which means the body is where regulation has to start.

Anasa works at that layer. It catches the physical shift early and gives you a beat — space between the reaction and what you do next.

That space is where impulse control, steadier relationships, and better decisions live.

It matters for your health, too. Sustained stress wears the body down over time, and catching it earlier is one of the few things that genuinely helps.

For a long time we've treated emotions as something to hide — a weakness, a liability, out of place in serious settings. But everyone has them, regardless of who they are. They aren't a flaw to manage out of you; they're physiological signals worth reading. Anasa treats them as exactly that: information from your body, not something to be embarrassed by.

And it's built to look like jewelry, not a wellness gadget — quiet, sophisticated, easy to wear every day. The regulation stays invisible. Only you know it's there.

The Science

The body responds
first.
Anasa works there.

When Anasa detects shifts in your breathing and heart rhythm associated with stress, it delivers a gentle haptic rhythm — or an auditory one — at about 0.1 Hz, roughly six breaths per minute. You don't have to think about it. You simply follow the rhythm.

01

Sense

Sensors read the shifts in your breathing and heart rhythm associated with stress — the physical changes that begin before your mind has named what's happening.

02

Respond

The device delivers a gentle haptic rhythm at about 0.1 Hz — roughly six breaths per minute — the resonance frequency of the cardiovascular system.

03

Resonate

Following the rhythm drives the baroreflex — the feedback loop that regulates blood pressure — into resonance, producing the strongest coupling between your breathing and heart rhythm.

04

Regulate

The result is a measurable shift toward a calmer physiological state — space between the reaction and what you do next, without conscious effort.

IThe resonance frequency

About 0.1 Hz — roughly six breaths per minute — is the resonance frequency of the cardiovascular system. Breathing at this pace produces the strongest, most efficient coupling between your breathing and your heart rhythm, known as respiratory sinus arrhythmia.

IIThe baroreflex

Breathing at the resonance frequency drives the baroreflex — the feedback loop that regulates blood pressure — into resonance. This is the physiological engine behind the shift toward a calmer state, and it doesn't depend on conscious effort.

IIIThe body comes first

Your body responds to stress before your mind has named what's happening. Emotions are the brain's way of labeling what's happening in the body — which means the body is where regulation has to start. Anasa works at that layer.

Emotional regulation isn't self care. It's healthcare.

The Vision

Technology that lives
inside what
you already wear

Anasa isn't trying to be another device. The long-term vision is licensing — embedding this technology into the jewelry and watches people already love. The intervention becomes invisible because the object already belongs.

Built by someone who
learned to breathe first

I've always been more interested in people than almost anything else. What makes someone react the way they do. Why the same situation hits two people completely differently. How much of what we feel is actually what we think we feel. Psychology wasn't a major I chose — it was something I already was.

I grew up on South Padre Island, which sounds like a vacation but was just home. I surfed, played drums, spent too much time in my own head in the best way. Health has always been a constant — I've been in the gym consistently since high school, not for how it looks but because I believe in taking care of the body you live in. Anasa comes from that same place. Emotional regulation isn't self care. It's healthcare.

The people who raised me were each building something. My stepdad turned a contractor's instinct into the biggest beach bar on the Texas coast. My mom is a scientist and a builder — she ran her own dental practice in South Texas and never needed a blueprint. My dad ran 37 marathons, pioneered emergency medicine in the Rio Grande Valley, and still talks about the human spirit like it's a science. I grew up thinking that level of drive was normal.

Anasa is what happens when you spend your whole life paying attention to people — why they dysregulate, why they can't get back, and what it would take to make that easier. I'm 20 and building it now because the question felt too urgent to wait.

The Inspiration

Art that made
something feel possible

Frida Kahlo

Boldness · Femininity · Color as identity

Frida taught me that you can be completely, unapologetically yourself — and that is the art. Her work is bold and feminine and overflowing with color, not because she was making a statement, but because that's just who she was. That energy lives in Anasa's aesthetic. Not because this is a device for women — but because it was built by someone who moves through the world the way she painted. Fully, specifically, without apology.

Mark Rothko

Emotion · Immersion · Color that breathes

Rothko taught me that something can make you feel deeply before you understand why. You stand in front of one of his paintings and your chest does something you can't explain. That's what I wanted Anasa to feel like — not a gadget, not a wellness product, but something that moves you before you can articulate it. His color fields breathe. That word — breathe — is not a coincidence.

The name: Anasa

Anasa is the Greek word for breath. It wasn't chosen for how it sounds — it was chosen because breath is the mechanism. Everything the device does leads back to one thing: helping your body find its breath before you even know you've lost it.
