window of tolerance
/ˈwɪndəʊ əv ˈtɒlərəns/
CommonThe zone where you can handle stress and think clearly, without going into overdrive or shutdown.
Widely used in therapy contexts. Online it gets used more casually, but the concept translates well: it is basically asking 'how much can you handle before you lose it or check out'.
