Reducing the amount of narcotic gases in your mix so you don’t act like a drunk idiot when in a life threatening situation.
Those narcotic gases are nitrogen and oxygen (although there’s only so little oxygen you can have…and also only so much!)
Edit: extra info: oxygen and nitrogen are narcotic at depth, nitrogen is better understood and so often we talk about nitrogen narcosis, which tends to start hitting people after about 30m, but each person reacts different and to different degrees at different deaths. I personally notice it at about 50m or so. If I was more relaxed while diving it’d probably hit me sooner.
Enough to make me never want to even attempt such a thing, myself! But I did know of the helium ratio stuff because of it, so it’s still educational content.
What is helium used for when diving?

Was that supposed to say depths?
Yes. Yes it was.
I’ve seen enough of YouTuber, Scary Interesting, to believe that either word would work!
