Square Breathing in Cold Water
Square breathing is approximately 4-4-4-4:
- 4 second inhale
- 4 second hold
- 4 second exhale
- 4 second pause
However, we find that counting the breath gives the exercise a mental quality.
This is ok for when you are starting out, but ultimately we recommend people do short, mid or long breaths/holds/pauses because this is more qualitative and conducive to feeling each breath/hold/pause.
Square breathing is excellent for building resilience to stress - which is why we recommend practising it immersed in cold water.
Doing cold showers/baths it for 11 minutes total each week is said to be the "sweet spot" for getting maximum physiological benefits and yet not getting too habituated to the cold.
