just found out how quickly co2 builds up

I was curious about the levels of CO2 in my room so I went and bought a sensor for my bedroom. I was somewhat appalled when I woke up this morning with heavy eyelids to see the concentration at 1700 ppm.

Guess I have to leave my door open now.

Does your HVAC have a "circ" setting? On mine, it turns on the fan only (i.e. no climate control, just air movement) every 30 minutes.
In the event of a house fire, a closed bedroom door can truly save your life.
- Oh huh, maybe I should install a cat door on my bedroom door. Though my landlord would probably not like that very much
  
  Doors come off their hinges super easy with usually 6 phillips head screws. Remove the existing door, stash it, install whatever door you like with attached cat door. When you move out, reinstall the old door.
Sitting at a stop light on my motorcycle caused enough CO2 from my breath to build up inside my helmet that I became dizzy and had to pull aside and open my visor and breathe.
So you sleep between 2 and 10 am with no ventilation. RIP lungs.
Now we're cooking with gas!
Do you have a fan to circulate air at all?
I went down the rabbit hole on this. Plants cannot help because it takes like 100 fast growing Palm trees to offset one person or something like that. Your only option is ventilation. I did this by installing a switch to the bathroom fan, which is connected to my room and expels the air outside, meaning it must pull in air from outside from some poorly sealed door or window somewhere. The switch I set to go during the hours my wife and dog and I are all sleeping in the room with the door closed and it solved the problem.
- I've got a fan box that pulls air from the outside and puts it through a heat exchanger against air from the inside. Fresh, filtered air and about 90% energy recuperation. Condensate drips down on the pipes on the outside and finally I can sleep with a somewhat free nose during allergy season.
