Somatic · Ember Science

Designing for the body, without pretending certainty.

Ember Science is our evidence practice for breath, orientation, sound, and motion. Every claim carries a grade, a source, and the limit.

The science

Ember Science · the levers

The body often reacts before language catches up.

Stress often reaches the body before a person can name what is happening. Breathing changes, muscles brace, and attention narrows. Language still matters, but it may not be the first useful input.

Breath, orientation, and interoception are not equally well supported. Ember Science names that difference, keeps the source close, and shows where a product claim must stop.

Vagus nerve

Lever one

The exhale

Well established

A slower breathing pace can change beat-to-beat heart-rate patterns and may reduce short-term arousal.

Breathing and heart rate interact through respiratory sinus arrhythmia and baroreflex pathways. Slow-paced breathing, often near a person’s resonance frequency, can increase heart-rate variability during practice. That does not prove a longer exhale is universally calming or therapeutic. The studio uses it as an optional pacing cue, not a diagnosis or cure.

Lever two

Orienting

Mechanism only

Where the eyes go, the rest of the body tends to follow.

Under threat, attention narrows and locks. Safety looks different: the eyes move, the field widens, the head turns and takes the room in. Products can offer that shape back, with slow lateral movement and somewhere wide to look. The biology of the orienting response is well described. The claim that a particular way of looking reliably lowers arousal in people is not settled, and this page will not pretend otherwise.

The biology is documented. The human outcome evidence is not there yet.

No outcome trial to point at

Lever three

Interoception

Promising

Regulation starts with noticing, and noticing can be trained.

Interoception is the sense of your own inside: heartbeat, breath, tension, the churn under a feeling. It is measurable, in eight dimensions, and the dimensions that track hardest with anxiety and depression are attention regulation and trusting the body. Body-based trauma therapy works this lever directly, and the early controlled trials are good. There are not many of them yet.

Real controlled trials exist. The evidence base is still small.

The brake

Slower is not the point. Resonance is

Almost every breathing product tells you to slow down, as though the effect keeps growing the slower you go. It does not. There is a resonance point, and going past it costs you. Find it on the dial below.

The brake, at three speeds

Well established

6.0breaths / min

at resonance

Here the breath meets the baroreflex and the swing opens all the way out. This is the one the products are tuned to.

An offer, not a prompt.

The trace is a model of the mechanism, drawn from the published curve shape. It is not a reading of your heart, and nothing here is measuring you.

The evidence

The numbers, and what they do not say

None of these are our numbers. The studio has not run a clinical trial, and a figure borrowed from the literature is a reason to build something, not proof that what we built works. Every one below is printed with the caveat that belongs to it.

0.81Hedges' g

Effect of heart rate variability biofeedback on self-reported stress and anxiety, pooled across 24 randomized trials and 484 people.

The caveat · Pre-post within group. The between-group figure against a control was 0.83. Self-report throughout.

Goessl, Curtiss and Hofmann, Psychological Medicine, 2017

5minutes a day

Exhale-led cyclic sighing beat mindfulness meditation on daily mood and on breathing rate, over one month, in 108 people.

The caveat · The same trial found no significant change in heart rate variability or resting heart rate in any group.

Balban et al., Cell Reports Medicine, 2023

~175neurons

A cluster inside the breathing rhythm generator wires straight to the alarm center of the brain. Remove it and breathing carries on unchanged, but the animal is calmer.

The caveat · Mice. This is why breath reaches arousal at all, not evidence that any breathing exercise works.

Yackle et al., Science, 2017

6breaths a minute

Around 0.1 Hz, breathing lines up with the baroreflex and the swing in heart rate is at its widest. Faster and slower both narrow it.

The caveat · The exact resonance point differs person to person, and is not perfectly stable within one person over time.

What the studio will not claim

That any Martori product is a treatment, or a substitute for one. None of them has been through one.
That a breathing exercise resolves heartbreak, grief, or dependency. It changes the next few minutes, which is often enough to get through them.
That reading a vagal mechanism in a paper means our implementation of it works. Those are two different claims, and only the first one has evidence.
That the third lever is as solid as the first. It is not, and it is labeled that way everywhere it appears on this page.

Feel it for yourself

This field is listening to your hands.

The mechanisms above are the argument. This is the demonstration, and it is the whole design principle in one object: the field takes your pace instead of setting one. Move through it however you arrive, then slow down and watch it follow.

In practice

Four products, three levers

Each one meets a different kind of pain and uses a named lever rather than a mood. Across all four, the rule is concrete: offer a cue, show its evidence, and never turn a physiological mechanism into a promise of recovery.

Sanctuary

Live · free

a world for the long fog after a breakup

The exhale
Interoception
companion · Dove

Heartbreak is not only a mood. Imaging people who had recently been rejected and were still in love lit up the reward and craving circuitry that shows up in addiction, which is why the early weeks feel like withdrawal rather than sadness. Sanctuary meets that with a long exhale, warm color, and a room that never raises its voice.

The long exhale: the breath the product opens with, every time
The cairn: a count that holds through a hard day instead of resetting

The caveat · The rejection imaging study ran 15 participants. It is a small, much-cited scan, not a treatment trial. Read the paper.

built for the hours between meetings

The exhale
Interoception
companion · Heron

A craving arrives in the body before the mind has a word for it, and a cue-driven one usually crests and passes in minutes rather than hours. Marrow is built for that window: grounding and slow breath while the wave goes over, and a pointer to the signal underneath it once it has.

The shallows: somewhere to stand while the urge crests
Crossings: the unstructured stretch between meetings, named and held

a quiet companion for life after a loss

Interoception

Grief settles into the body and stays there. Vigil gives it somewhere to move rather than somewhere to be fixed: slow body scans, weighted breathing, open space, one room at a time. No notifications, and nothing rushing anyone toward a closure they did not ask for.

somewhere to go when the body will not settle

Orienting
companion · Mira

The one whose medicine is wonder. Nine celestial anchors mapped to real constellations overhead, so the sky in the product is the sky outside. Of several positive emotions measured against an inflammation marker, awe was the one that held up most consistently, which is a good reason to build somewhere vast and a bad reason to promise anything.

The drift: touch, and the cosmos parts around you
The field log: a record of what you found, never a tally of what you missed

The caveat · That awe finding is correlational, across two student samples. It shows an association, not that looking at a sky changes your blood. Read the paper.

The fourth input

Privacy is a somatic principle

There is no research grade for this one, because it is a design position rather than a finding. It follows from the rest all the same. A body does not settle somewhere it does not trust, and being quietly measured is something a person can feel long before they can name it.

On-device

Your breathing, your pace, a hard day, all read on your own phone. The most personal data never leaves your hands.

Tuned, not profiled

It adjusts to how you are right now, not to a model of who you are. Better for you, without learning to predict you.

Built to be outgrown

Nothing here is designed to hold you. A product that needs you to keep coming back is pulling against the thing it says it is for.

Your nervous system was built for threats that were physical and brief. Heartbreak, grief, and addiction did not come with a manual. We are writing one, and showing the working.

Design for the body in the room

Make the interface meet the moment before words.

Somatic work needs restraint, evidence, and honest limits. We can help shape the interaction without making claims the product has not earned.
