People who post on X between 11 p.m. and 5 a.m. report significantly lower well-being than daytime users, according to new research from the University of Bristol. A study of 310 UK adults analyzed over 18,000 tweets alongside mental health questionnaires. "The average hour participants posted tweets explained almost 2% of the variation in mental wellbeing, comparable to reports of the impact of binge drinking and exercise," researchers wrote in Scientific Reports. However, connections to depression and anxiety were minimal, explaining only 0.2% and 0.7% of symptom variation respectively. Peak well-being occurred around 6:50 p.m., while lowest scores belonged to people tweeting around 2:20 a.m. Lead researcher Daniel Joinson suggests sleep disruption may explain the well-being impact.
