EYANA \u00b7 to breathe
Breathwork, explained by a cardiologist.
Rigorous about what the evidence shows, honest about what it does not, and built to give you something useful to do in the next ninety seconds. Wherever in the world you are.
Health education, not medical advice. Never start, stop, or change medication based on what you read here.
A cardiologist\u2019s case for the breath
I read hearts for a living, and the heart cannot be slowed by command. You cannot will your pulse down. The breath can, and through it, so can the heart. Slow your exhale and a feedback loop called the baroreflex nudges your heart rate down and your blood pressure toward calm. This is not metaphor. It is measurable, and it happens whether or not you believe in it.
The internet has enough breathwork content. What it does not have is a resource that is honest about the evidence, accurate about the mechanism, and written by someone who works with the organ at the center of it. That is what EYANA is. Every technique here carries a rating. Every claim links to the study behind it. And every page tells you when the honest answer is that we do not know yet.
Five places to start
EYANA is built as five pillars: the science, the techniques, what you are feeling, your life and work, and the honest limits.
Pillar 1 of 5 · Mechanism
The science of breath and the heart
The cardiologist’s intellectual home. Almost everything breathwork does runs through one pathway: breath rate moves intrathoracic pressure, which moves the baroreflex, which moves cardiac vagal outflow, which moves your heart rate, blood pressure, and heart rate variability. Explained from your own chest outward, in plain English, accurately.
Pillar 2 of 5 · Techniques
Breathing techniques, rated by evidence
Every technique gets one canonical page in the same shape: what to try in sixty seconds, the mechanism in plain English, the evidence with a Breath Honesty Scale rating, and an honest section on when not to do it. No technique is oversold. The rating tells you how much the evidence actually supports.
Pillar 3 of 5 · States and conditions
Breathing for what you are feeling
Organized by what you are feeling, not by technique name. Each page matches your state to a technique using the Cardiac Breathwork Ladder, and tells you the truth about how strong the evidence is for that use.
Pillar 4 of 5 · Audiences and contexts
Breathing for your life and your work
The same physiology, met where people actually live and work. Race-conscious and continent-aware by reflex, faith-respectful without contesting tradition, and honest about thin evidence wherever it is thin.
Pillar 5 of 5 · Honest limits
The honest limits of breathwork
EYANA’s structural moat: the content competitors will not write. Where the evidence is thin, contested, or wrong, this is where we say so plainly, with respect for your intelligence. Honesty is the brand.

The Breath Honesty Scale
What EYANA promises you, on every page
1. We cite primary research
Every specific claim links to the original study, not a secondary article about it. Author, year, journal, DOI. You can check our work.
2. We tell you when the evidence is thin
When the science is early, small, or contested, we say so, in plain words, with a Breath Honesty Scale rating on every technique.
3. We never tell you to stop your medication
Breathwork is one supportive tool. Medication is medicine. Breathwork is what you do in addition, not instead.
4. We explain the mechanism in plain English
Every page tells you what is happening in your body, in accurate physiology a curious fifteen-year-old could follow, not jargon and not metaphor.
5. We give you something to try in ninety seconds
Every page has a technique you can do right now, with no equipment. You leave having learned something and having done something.
Breathwork, answered honestly
Is breathwork backed by science?
Partly, and EYANA tells you which parts. Slow breathing at about six breaths a minute reliably increases heart rate variability in the moment, and that evidence is solid. A 2023 meta-analysis of twelve trials found small-to-moderate reductions in stress and anxiety. Claims like boosting immunity or rewiring your nervous system are not supported. Every technique on EYANA carries a Breath Honesty Scale rating from Solid to Unsupported so you can see the difference.
Can breathing exercises lower blood pressure?
Modestly, as one supportive habit. Across seventeen randomized trials, slow breathing lowered resting systolic blood pressure by about five to six mmHg on average (Chaddha 2019). A 2021 Colorado trial found that training the breathing muscles against resistance for five minutes a day lowered systolic pressure by about nine mmHg. These are real numbers. They sit alongside medication, not instead of it. Never adjust medication without your physician.
What is the fastest breathing technique to calm down?
The physiological sigh: a double inhale through the nose followed by a long exhale through the mouth. It re-inflates collapsed air sacs and clears carbon dioxide within seconds. EYANA packages it as the EYANA Reset, a ninety-second protocol you can do anywhere with no equipment.
Is breathwork safe for everyone?
Most techniques are safe for most people, but not all. People with arrhythmias, heart failure, severe COPD, epilepsy, or who are pregnant should be careful, and high-ventilation methods should never be done in or near water. EYANA publishes the Mogire Contraindication Framework, three safety gates naming who should be careful with which techniques and why.
Who created EYANA?
EYANA was created by Dr. Job Mogire, a board-certified cardiologist and the founder of House of Mastery. The name is Ekegusii, his mother tongue, for the act of breathing. The resource is written from the cardiologist’s lens: what is happening to your heart while you breathe, in plain English.
The app is coming
Breathe with the first cohort.
EYANA is becoming a daily breath-training app for web, Android, and iOS: guided patterns with visual pacing, and a daily reminder to return to the breath. Join the waitlist and you breathe with the first cohort, free.
EYANA is health education, not medical advice. It does not diagnose, treat, or replace your physician, and nothing here is a reason to start, stop, or change any medication or treatment. If you have a heart or lung condition, read the Mogire Contraindication Framework first and talk to your doctor. If you have chest pain, fainting, or a racing heart that will not settle, seek medical care.
