Nestor offers five to six seconds in and five to six seconds out as a useful starting range for many adults, but he rejects the idea that everyone must hit an exact 5.5-second count. Rhythm should reflect the person: children naturally breathe faster, taller people may be comfortable slower, and someone with panic or low carbon-dioxide tolerance may need to begin at only two seconds in and two seconds out. The progression is deliberately gradual: establish comfort at two-and-two, then try three-and-three, four-and-four, and eventually a slower range. Once a rhythm is comfortable, wearable heart-rate-variability feedback can help a person explore their own response, but it is optional. The core decision rule is to advance only when the current pace feels easy rather than forcing a target.

Core principles
- 01Use a general rhythm as a starting point rather than a universal prescription
- 02Start where the breath remains comfortable
- 03Increase inhale and exhale duration gradually
- 04Expect children and people with low tolerance to need faster starting rhythms
- 05Use personal response, not precision, to refine the rhythm
How to run it
- 1
Choose a comfortable start
Test an equal inhale and exhale that feels quiet and sustainable. If slow breathing feels difficult, begin at two seconds in and two seconds out.
Pro tip Treat five to six seconds as a destination to explore, not an entry requirement.
Watch out Stop if paced breathing causes distress, dizziness, or air hunger that does not settle.
- 2
Stabilise the rhythm
Stay with the starting count until it feels natural rather than effortful. Keep the breath subtle.
- 3
Lengthen one step
Move from two-and-two to three-and-three, then to four-and-four only after each prior rhythm is comfortable.
Pro tip Small increases are easier to evaluate than jumping directly to a very slow rate.
Watch out Do not compete with another person's cadence.
- 4
Explore the general range
For many adults, try five to six seconds in and five to six seconds out. Adjust for comfort rather than chasing exact precision.
Pro tip Nestor suggests that body size and age can change the comfortable rate.
- 5
Refine with response
Notice how you feel during and after the practice. If available, compare HRV at nearby rhythms to explore which produces the strongest personal response.
Pro tip A wearable is an optional feedback tool, not a prerequisite.
Watch out A consumer wearable does not provide a medical diagnosis.
In the wild
A beginner feels strained at five seconds each way, so they practise two-and-two until it becomes easy. Over several sessions they move to three-and-three and then four-and-four, backing down whenever the breath becomes forced.
→ They develop a slower rhythm through tolerable steps rather than abandoning the practice after forcing an unsuitable pace.
Common mistakes
Forcing 5.5 seconds
Nestor explicitly relaxes the exact 5.5-second prescription because people became preoccupied with precision.
Advancing through air hunger
The progression depends on comfort; forcing a slower count undermines the decision rule.
Is it for you?
Best for
Beginners who want to practise slower breathing without forcing a single universal count.
Not ideal for
People who become panicked, dizzy, or unwell during paced breathing and need individual clinical guidance.
From the transcript
“a good first place to start is this five to six seconds in five to six seconds out”
“you have to start with two and two out”
“you find what's most comfortable for you”
