Oxygen and hypoxia problems when my brain is in calm state I need to make my brain stimulated all time

[youness]

When I lie down or enter a parasympathetic state, my SpO₂ can drop as low as 80%. I feel mentally slow, weak, disconnected, with dry saliva and fading taste—like I’m shutting down.

Staying mentally active (talking, thinking, moving my eyes) and being near fresh air improves it. But lying flat, deep relaxation, salt, and electrolyte drinks make it worse.

The more I close my eyes and ears and reduce stimulants, the worse the oxygen problem gets.

Paradoxically, things that usually calm inflammation—like sunlight or ice packs—trigger these episodes.

Does your heart rate go down as well?

When I have severe PEM, my heart rate goes down to 40bpm or even high 30s when I rest. But as soon as I move an arm or leg, it starts to go back up. My O2 doesn't go down though.

I wonder if drugs to improve circulation would help? I've been interested in pentoxifylline (Trental) but I haven't tried it myself. There's also sildenafil (Viagra) or gingko biloba.

If you can't get ahold of one of those maybe deep breathing will help get your O2 up? Or try lying on your stomach instead of on your back?
