Using Social Media at Night 'as Harmful to Mental Health as Drinking or Smoking'

Scrolling through social media before bed could damage your mental health as much as drinking alcohol or smoking cannabis, researchers warn.

A study from the University of Bristol revealed that people who posted on X (formerly Twitter) after 11 p.m. had “significantly poorer” mental wellbeing.

Researchers believe late-night phone use reduces both the amount and quality of sleep, which is already known to negatively affect the brain.

The study found that nighttime posting explained about two percent of the variation in mental wellbeing among participants — an effect similar to that linked to binge drinking or cannabis use.

According to a YouGov poll, nine out of ten Britons check their phones within an hour before going to bed.

Calls for Curfews and Wind-Down Features

Lead author Daniel Joinson stated, “Our findings highlight the possible risks of posting online at night. Studies like ours could guide policies or app features designed to prevent harmful social media habits.”

The research, which analyzed data from 310 UK adults, compared the mental health of those who posted on X between 11 p.m. and 5 a.m. with those who posted during the day.

Results showed that late-night users scored an average of four to eight points lower (on a 70-point scale) for mental wellbeing.

Writing in Scientific Reports, Joinson added that the findings support the idea of introducing curfews or “wind-down” settings in apps to discourage nighttime scrolling.
