We have lungs and breathing but as far as I'm aware it doesn't affect much.
Smoke from fires.
Outside, 1 tile around the fire is a little darker from smoke, a colonist in it for 2 long begins to suffer from asphyxiation, eventually collapsing and later leading to death.
Indoors is the real issue. (like heat wasn't enough)
Black smoke builds up quickly.
It can be vented by leaving doors open.
Anyone in a room full of smoke will succumb to it in the same way as above.
Also, if you extinguish a fire or it expires itself and the room isn't vented, black smoke looms indefinitely.
