is low a verb?

[Serzige]

Ok guys this is gonna be quick...
If I say "a warm-up is used to lower the affective filter", how could I say this phrase in other words. And please, give me "to lower" in other situation...

Thanks again.

We lowered him carefully onto a stretcher.
The clouds lowered and darkened, and it began to rain.
