People who have more words for feelings seem to handle their emotions better

Psychologist Lisa Feldman Barrett calls it 'emotional granularity': the ability to distinguish between irritated, resentful and disappointed instead of lumping them all under 'bad'. People who draw these finer distinctions show more flexible coping and better regulation under stress, suggesting the vocabulary for an emotion isn't just a label but part of how precisely it's actually experienced.
