Because breathing is directly wired to the parasympathetic nervous system, a short daily practice of full inhales and complete slow exhales, paired with deliberate mental relaxation, activates the rest-and-digest response and raises HRV. Jamieson keeps it deliberately simple: roughly five minutes a day of slow, full breathing where you fully empty the lungs and mentally disengage from stress. To make it concrete and self-correcting, you watch your heart rate and try to drive it as low as possible, using the number as live biofeedback for whether you are actually relaxing. The skill carries over, improving sleep and the ability to downshift throughout the day. The biggest responders are type-A people who are always switched on; teaching them to flip the relaxation switch, even briefly, compounds into better sleep and recovery.
Origin
Distilled by Joel Jamieson from working with breathing specialists and stressed clients, drawing on established breathwork approaches that all converge on slowed, controlled breathing with a prolonged exhale to activate the parasympathetic system.
Core principles
- 01Respiratory function is tightly coupled to the parasympathetic system
- 02A prolonged, complete exhale drives the rest-and-digest response
- 03Learning to switch off the stress system is a trainable skill
- 04Heart rate is a simple, honest biofeedback signal for relaxation
- 05Type-A, always-on people gain the most from deliberate downshifting
How to run it
- 1
Schedule five minutes away from training
Pick a consistent daily slot, separate from your workout, to practice. Even five minutes is enough to start shifting HRV upward.
Pro tip Anchor it to an existing routine, like a morning ritual, so it actually happens daily.
- 2
Breathe full in, full slow out
Take complete inhales and long, controlled exhales, fully emptying the respiratory system on each breath out. The prolonged exhale is what drives the parasympathetic response.
Pro tip Getting a complete exhalation matters more than a big inhale.
Watch out Progressive overload of breath holds can feel like drowning while not underwater; expect discomfort.
- 3
Relax the mind at the same time
While breathing, consciously disconnect from surrounding stress and let the body settle. The combination of full breathing and mental relaxation is what resets the stress cycle.

Use heart rate as biofeedback
Watch your heart rate during the drill and try to drive it as low as possible. A falling heart rate confirms the parasympathetic system is switching on.
Pro tip Beginners often fail at first by trying too hard, which keeps heart rate up; the goal is to let go.
Watch out Straining to force the number down is counterproductive.

Progress positions and let it carry over
As you improve, practice lying, then seated, then standing. Over weeks the ability to downshift transfers into better daily stress response and sleep.
Pro tip If nothing else, do it for the improved sleep, which then improves a cascade of other outcomes.
In the wild
Jamieson describes taking someone who is always on, such as a powerlifter who cannot relax, and having them spend five minutes in the middle of the day doing the breathing drill while trying to drive their heart rate as low as possible. At first they suck at it because they try too hard, but they learn to relax on cue. The biggest impact shows up in exactly these high-strung, low-HRV people, who then sleep better and see downstream benefits.
→ A learned ability to activate the parasympathetic system, better sleep, and a rising HRV.
Common mistakes
Trying too hard to relax
Straining to force the heart rate down keeps the stress system engaged and slows the parasympathetic response; the skill is to let go, not push.
Treating it as a one-off
The reset works through daily repetition that trains the nervous system; a single session will not durably raise your baseline HRV.
Is it for you?
Best for
Chronically stressed, high-strung people who struggle to relax and have low HRV.
Not ideal for
Anyone expecting a one-off session to permanently change their baseline without daily repetition.

“if you can spend five minutes a day doing that you will i guarantee you'll see your hiv go up a little bit”
“just go these breathing drills and look at their heart rate and your goal is to get your heart rate as low as possible”
