Alternatives To Bag Breathing?

[Apple]

surgical masks have microplastic fibres and phthalates which are endocrine disruptors , dont wear them carelessly

surgical mask can be replaced with self made masks if you are afraid of microplastic fibres...
I've been wearing a thick mask for a weak when going out and feel great! ( levels of CO2 definitely increased)
wearing a mask in context of pandemic is peaty :)

The whole world is so relaxed and healthy since the mask mandates ?

Bag breathing seems like a huge chore for me, never really find the time to sit down and have a good 10 to 15 minute bag breathing session. When I have on the few occasions, I've always been disappointed with the results. I have a soda stream machine that comes with co2 tanks, technically it's suppose to be used to make carbonated water. Could you possibly blow some co2 (from the tank) into a bag or balloon and breath it in? It would seem like a more concentrated dose of co2, rather then re-breathing through a bag.

Did you ever find out if it's safe to put some co2 in a balloon and breathe in small amounts??
