When hypomania turns harmful, from the Harvard Mental Health Letter
Artists, entrepreneurs, and other creative people tend to be energetic and inventive, bursting with new ideas, and more than ready to talk about them. These are also some of the characteristics of hypomania, reports the Harvard Mental Health Letter. Hypomania is a mood state or energy level that is markedly higher than "normal" but not as extreme as the mania that accompanies bipolar disorder.
The hallmarks of hypomania include exaggerated self-esteem, decreased need for sleep, increased talkativeness, racing thoughts or ideas, marked distractibility, agitation, and excessive participation in pleasurable activities that tend to invite personal or financial harm, such as sexual indiscretions or impulsive business investments.
