> CO2 levels inside a building can have a stimulating effect on the body, which kind of destroys the purpose of a relaxation of a home

Citation really needed.




You know where google scholar, pubmed and wiki is? Or do you want to get into a discussion about under-carboxylation and dietary intake of nutrients, and CO2 blood saturation levels?

I know them quite well but this is a conversation on HN and people should back their claims here.


Well you can see that breathing is stimulated with rising CO2 levels, everyone knows this whether they have exercised or held a non-permeable bag over their head.

Its interesting because Climate Change aka rising CO2 levels will stimulate the population globally which then presents a new area of concern for authorities who like to keep control of a population. Hadnt thought of that until now!


You are throwing around the word "stimulating" in a very misleading way.

If don't have good circulation in your home your respiration rate is going up by an unnoticeable amount. The idea that this prevents "relaxation" is absurd.

Equally absurd to claim "presents a new area of concern for authorities who like to keep control of a population".

If anything it's the very opposite, where *high* levels of CO2 *decrease* attention and causes drowsiness.
