Rewatching Episode 1: The Phantom Menace, and one of the first scenes shows a young Obi-Wan and his master, Qui-Gon, being trapped in a waiting room. The room starts to fill up with Dioxis, a toxic gas. They take deep breath, long enough to survive until the room is opened. But how long was that? Were they using the Force to do it? How long can a Jedi hold their breath with the Force?
Notably, both Obi-Wan and Qui-Gon had to use a rebreather type device while swimming down to the Gungan city Otoh Gunga, instead of just holding their breath. So there seems to be a limit?
