While it's clear exercise is good for everyone, this statement is not well informed.

For example, oxygen saturation monitoring revealed my at-rest breathing reflex is completely broken due to a known genetic flaw. You know the memes about 'your breathing is now under conscious control'? Mine actually is.

That led to a sleep study-- and, yup, I don't breathe when I'm asleep. I wake every two or three minutes, all night, take a few breaths, and go back to sleep. And have all my life. The mystery of why I'm 'such a light sleeper' also revealed.

Doc I saw about it remarked the mutation is probably more widespread then we know because 'no one is looking for it'. It also completely freaked out a few anesthesiologists.

[There are other reflexes around breathing, and no, I can't just hold me breath as long as I want. The physiological reminders to breathe are pretty strong! But I routinely see my SP02 at rest drop below 70.]

What became your solution to this situation?

What is this mutation and how do I test for it?

Is this true? I run ~15 miles a week, play pickup basketball 2x a week, and lift weights 3x a week. My oxygen levels can vary 2-5% depending on circadian rhythm at rest. When doing these breathing exercises, I can stabilize it at higher levels. That's at least my experience with it.
