(Daily Mail Online) — Binge-watching TV can make you feel like a zombie, according to a recent study.

Researchers at the University of Michigan and the Leuven School for Mass Communication Research in Belgium found that higher binge-viewing frequency leads to poorer sleep quality, more fatigue and increased insomnia. The researchers found the negative symptoms are associated only with binge-watching and not watching TV for shorter periods of time.

In a study of 423 adults who binge-watch at different rates and duration, researchers found higher binge-viewing frequency leads to poorer sleep quality, more fatigue and increased insomnia.

“Our study signals that binge viewing is prevalent in young adults and that is may be harmful to their sleep,” said co-author Jan Van den Bulck, a U of Michigan professor of communication studies.

For the study, the researchers surveyed 423 adults between the ages of 18 to 25 about their binge-watching habits in the past month to learn about effects on sleep quality, insomnia and fatigue.
