Idioms meaning Relax

Question

I know that in english we have a lot of idioms for the command relax (like cool it, mellow out, chill, etc.) and I was wondering if there were any spanish idioms for it as well, or if any of the english ones translated into spanish would be understood.

Thanks for any help you can give.

No te preocupes - don't worry about it. Cálmate - chill

Answer 2

Cójelo suave---Take it easy

Answer 3

tranquilo is very common for no problem; take it easy; calm down; it's nothing.
