1/7 On sleep apnea (I am not a doctor and this is not medical advice.)

2/7 You may note that you can lay on your back or side and still breath if you consciously/reflectively/deliberately maintain your airway. The reason for involuntary/unconscious airway collapse is that your blood CO2 levels become too low, so the body...

3/7 ...(over)collapses the tongue/throat/airway to preserve lung CO2 concentration.

4/7 Blood CO2 goes too low because of “overbreathing.” Overbreathing occurs when (a) the CO2 breathing trigger is set to fire at too low a concentration and (b) when the body chronically overbreathes at too high of a rate or depth. Being very still, for long...

5/7 ...periods of time, while doing stressful things, and not periodically massively spiking CO2, will ultimately cause overbreathing.

6/7 (a) can be cured by a combination of max-intensity interval training (most important) to spike blood CO2 combined with (less important) 40-90 minutes of aerobic exercise, 1-3 times per week.

Any tips on this? I tried just running as fast as I could and that felt good but in the past I haven't been able to sustain the habit. Think there are probably things wrong with my form, I did notice that I was tensing a bunch of muscles unnecessarily.
