Lyrically, the song deals with the idea of letting go of worries and living in the moment with someone you are romantically involved with, even if doing so feels like 'hysteria'.

Abreu encourages people in such a situation to 'start breaking some rules' and challenges with the rhetorical question 'what's life without a sin?'

"Hysteria" debuted and peaked at number six on the Finnish Top 20 Singles Chart, a position it held for two non-consecutive weeks.

The video begins with Abreu, wearing a worker's boiler suit, working in the factory alongside a love interest.

Throughout the video, we see another version of Abreu, wearing a long dress (and seems to represent the 'sin' of the lyrics), dancing in the factory and seducing the male co-worker.
