Polite Ways to Say "Calm Down"
The most reliable polite options are "Take a deep breath" and "Try to stay calm" — they ask for the same thing as "calm down" without sounding dismissive. The trick is to add a small acknowledgment first ("I can see this is frustrating…") so the person feels heard rather than managed.

Common mistakes
Take a deep breathe.→ Take a deep breath."Breath" is the noun; "breathe" is the verb, so the phrase needs the noun form.
