Binge-watch has been dubbed the Word of The Year, with a 200 per cent increase in use, thanks to the onslaught of streaming services enticing viewers to settle in for several episodes in one sitting.
With its rise in popularity, a team of researchers set out to review binge-watching's effects.
In a study of 406 people, researchers from the University of Toledo's Department of Health and Recreation recorded how much TV the participants watched each night, and how they felt as they viewed.
The study found 77 per cent watched at least two hours of programmes a night, classing them as 'bingers'.
While 35 per cent watched far more, the two hour mark saw participants reporting feeling more depressed and anxious than those who spent less time.
