A mild form of mania that can occur as part of a mood disorder, often characterized by increased energy, reduced need for sleep, and heightened mood.
During her episode of hypomania, she felt more energetic and creative than usual.
Hypomania is formed from "hypo-" (meaning under or below) and "mania" (from Greek "mania", meaning madness or frenzy). The term describes a state of elevated mood that is less severe than full mania, indicating a condition that is below the threshold of mania.
Think of 'hypo-' meaning 'under' and 'mania' meaning 'madness' — hypomania refers to a state of being under the full intensity of madness.
