Discussion Overview

The discussion revolves around the best methods for holding one's breath, with a focus on different techniques and their implications for breath-holding performance. Participants explore various approaches, including the timing of inhalation and exhalation, and the physiological aspects involved in breath-holding.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant suggests three options for holding breath: after inhaling, after exhaling, or that it doesn't matter.
  • Another participant argues that holding breath after exhaling may be detrimental and recommends a technique used by divers, which involves breathing in and out before taking a big breath and slowly exhaling while underwater.
  • A participant clarifies that their interest is in breath-holding as a competitive activity, such as breaking a world record, and seeks opinions on the best method for that context.
  • One participant proposes that maximizing lung expansion and managing CO2 levels is essential, mentioning the importance of maintaining favorable partial pressures of CO2 and O2 in the blood.
  • Another participant notes that rising CO2 levels can trigger panic responses and emphasizes the need to learn to suppress the urge to breathe, suggesting that freedivers may have valuable insights.

Areas of Agreement / Disagreement

Participants express differing views on the best method for holding breath, with no consensus reached on a single approach. Some emphasize physiological factors while others focus on practical techniques.

Contextual Notes

Participants discuss the physiological implications of breath-holding, including the effects of CO2 levels and the importance of lung expansion, but do not resolve the specific techniques or conditions under which these factors apply.

Best way to hold your breath?

Hi all, the question I'm about to ask isn't very serious it kinda just popped into my head, but one day the anwser may save my life or even yours :wink:. My question is what's the best way to hold you breath? Below there are 3 options you may choose but feel free to try and find some sort of middleground.

1. Hold your breath after Inhaling.

2. Hold your breath after exhaling.

3. It doesn't really matter.

Thanks in advance for any replies.

Trying to "hold" your breath right after breathing out sounds like a really bad idea :)

The best way (at least, what divers seem to do) is to breathe in and out a couple of times, then take a big breath, and while under water slowly exhale, i.e. release a little bit of air at the time.
 


when i say hold your breth i didn't exactly mean as in under water (i see how i gave that impression0, i meant hold your breath as though your trying to break the world record (Which probably won't save your life but you never know what the future brings :rolleyes:). Which of the options do you think would be best for that.
 


Well, if the only purpose to holding one's breath is to have a reservoir of oxygen available for a little while (since I don't know how much long the body's store of O2 can last), it would seem that you would want to expand your lungs as much as possible, and then as the partial pressure of CO2 builds up in the lungs, slowly exhaling to maintain favorable partial pressures of CO2 and O2 with respect to the blood.

That sounds pretty flaky... but I think that's the essence: to think about the combined hydrostatic and 'osmotic' pressures.
 


hmm, partial pressures aren't something i would have thought of. the CO2 is going to be mildly poisonous, but mostly the problem you will encounter is that rising levels of CO2 in the blood will trigger a panic response. some of the art will be in learning to suppress the panic and urge to breathe as CO2 levels increase.

the real experts to seek out though are probably the freedivers, even though the dynamics may be a little different.
