breathe easy

to assume a relaxed state after a stressful period. After this crisis is over, I'll be able to breathe easy again. He won't be able to breathe easy until he pays off his debts.

I agree with you all, if this is that speech is the speech of the character in the novel, play or whatever. But, while is this the speech of the narrator himself, then it should be "sighed deeply" or "sighed".

The verb is
فتنفسَت الصعداء
