According to a study from 2017, binge watching is correlated with various sleep problems:
The people who reported binge-watching were 98 percent more likely to report poor sleep quality compared with those who watched one episode per sitting, according to the findings.
However, the study only showed a correlation and did not touch on causal inference:
The study authors did clarify that there were limitations to the study since they saw only correlation between binge-watching, and not evidence of causation, or that binge-watching definitively causes poor sleep.
Is there a study that investigated whether or not there is a causal relationship between binge watching and sleep problems?
