Hi. I'm new to freediving. I recently read "The Oxygen Advantage" by Patrick McKeown after watching some of his videos and noticing that at least a few freedivers were taking his classes. However, after a couple weeks of following his program, I started having side effects. My sleep quality decreased and I started experiencing feelings of shortness of breath during the day and at night. I did not feel well. I stopped the program and things returned to normal.
Next I decided to do some apnea training with O2 and CO2 tables (phone app). After a couple weeks I am experiencing symptoms exactly like I did previously, even though the training is very different.
Initially I suspected I might have overdone the "The Oxygen Advantage" training, so (after returning to normal) I restarted my apnea training very gradually. I have worked up to 30 to 60 minutes a day of dry static apnea training and I am not pushing myself hard. I don't go as far into contractions as I think I could. I have never passed out. The training is actually pleasant. But again, my sleep quality decreased and I started experiencing feelings of shortness of breath during the day and at night. I feel fatigued.
Suspecting a possible health issue, I had a very thorough exam, including an exercise stress test to 100% of max HR. I passed all medical tests with flying colors.
Because two very different types of apnea training have resulted in very similar side effects, I am at a loss as to what to try next. I am looking for suggestions please.
