We all know that the gas could be hydrogen sulfide or methane or someting nitrous depending on what consume. But this doesnt explain how it passes through glass windows/doors.
The sun emits infrared / UV radiations that can penetrate through glass and hence heat up our car interiors. Obviously, this heat radiations that the sun emits is odorless but perhaps our bodies emit similar radiations that are heaty and suffocating. Just few gases have a wavelength strong enough to pass through glass since their particles are small enough to penetrate.
Ive a feeling it isnt hydrogen or methane but something else. Perhaps if we could get some insight on this then we could find antibiotics to reduce this emission. Thoughts?
