SOCIAL media before bed might be as bad for your mood as boozing or smoking weed, say scientists.
A study by Bristol University found people who posted on X, aka Twitter, after 11pm had “meaningfully worse” mental health.

The researchers reckon staying up late on your phone means you sleep less and have poorer quality shut-eye, which is known to impact the brain.
They estimated posting at night accounted for two per cent of the variation in someone’s mental wellbeing.
The effect was equal to what previous studies have pinned on binge drinking or using cannabis.
Polling by YouGov shows nine in 10 Brits look at their phones within an hour of going to bed.
Supports case for curfews or wind-down features
Study author Daniel Joinson said: “Our paper highlights the potential harm of night-time content posting.
“Research like ours could help inform interventions or legislation that aim to deter harmful social media use.”
The study used data from 310 UK adults to compare the mental health of people who tweeted late – between 11pm and 5am – with people who posted in the daytime.
It found the night owls scored an average of four to eight points lower out of 70.
Writing in the journal Scientific Reports, he said the results support calls for curfews or “wind-down” feature in apps to help people stop scrolling at night.
