Adipose-tissue plasticity in health and disease (opens in new tab)

Shower thought based on a few observations..:

1. if you breathe in a room with closed windows, the ambient co2 levels can quite easily exceed 1100ppm (that happened for me this morning ! I felt like shit til I saw my co2 meter reading and opened some windows!)

2. it will continue to increase until basically you hit some steady state involving the number of co2 molecules that swap places (ie 50/50 chance of increasing or decreasing ambient room co2 per breath)

3. co2 ppm level inside of your lungs is a lot higher than ambient air - one source says:

    inspired air contains 0.03% CO2 but expired air contains 4% CO2

for 300 ppm air. But if you're breathing let's say 1000 ppm. The ratio out/in goes from 4/0.03 to 4/0.1; from 133x to 40x.

4. when you burn fat, more of it is the co2 you breathe out than the co2 you urinate

5. for the co2 gas in your blood to become co2 gas in your breath, it has to undergo gas exchange - see last diagram on https://courses.lumenlearning.com/boundless-biology/chapter/...

conclusion: maybe proper ventilation and fresh air actually makes it a lot easier for you to release co2 from burning fat, in addition to actually making you feel a lot better??
