What if the problem with social media isn\u2019t just how much we use it, but when? A new study suggests that scrolling and posting through the small hours may be a red flag for mental wellbeing \u2013 and the effects could be as significant as binge drinking.<\/p>\n

For the study, published in\u00a0Scientific Reports<\/a>, my colleagues and I analysed the Twitter (now X) habits of 310 adults and discovered that those who regularly posted between 11pm and 5am showed meaningfully worse mental wellbeing than daytime users.<\/p>\n

This finding challenges the\u00a0current policy obsession<\/a>\u00a0with screen time limits and points toward a more nuanced understanding of how social media affects our mental health.<\/p>\n

Australia has passed a law\u00a0to ban<\/a>\u00a0social media for anyone under 16, with\u00a068% of the population<\/a>\u00a0supporting the new law.\u00a0Similar proposals<\/a>\u00a0are\u00a0being debated<\/a>\u00a0across the\u00a0western world<\/a>, where policymakers cite rising concern about youth mental health. But is the solution that simple? Science tells a more complicated tale.<\/p>\n

Studies examining social media use have\u00a0found associations<\/a>\u00a0with worse mental health, better mental health and even\u00a0no change at all<\/a>. And a large\u00a0analysis of over 350,000 people<\/a>\u00a0found that while more time on social media was associated with poorer mental health, the effect was minuscule.<\/p>\n

The trouble with this research is its fixation on amounts of time spent on social media.<\/p>\n

Two people might spend identical amounts of time on social media yet have completely different experiences \u2013 one scrolling passively, the other engaged in fraught late-night exchanges. The difference in behaviour matters, and so does the platform where it occurs.<\/p>\n

Complete bans will eliminate harmful effects, but they also remove potential benefits. Many young people rely on these platforms to form and maintain friendships. For those already struggling mentally, social media can provide support, guidance and community that might otherwise remain out of reach.<\/p>\n

On the other hand, late-night use could push back bedtimes, fracture sleep quality and consequently harm mental health. The harm may intensify with highly interactive activities \u2013 posting, messaging \u2013 compared with passive browsing. Understanding what people do on social media \u2013 and crucially, when they do it \u2013 is essential to grasping its real effect.<\/p>\n

The night shift: what we found<\/strong><\/p>\n

Our study explored this using real-world Twitter data from participants in the Avon Longitudinal Study of Parents and Children, matched with detailed self-reported mental health measures.<\/p>\n

These include the Warwick-Edinburgh Mental Wellbeing Scale \u2013 a 14-item measure of how someone feels and functions. We produced statistical models, aiming to predict these measures of mental health from the average time of day our participants posted their tweets.<\/p>\n

We found strong evidence that the time someone posts on Twitter was associated with their mental wellbeing.<\/p>\n

Posting time accounted for about 2% of the differences in wellbeing between participants. This may sound small, but it\u2019s a similar effect size to that found for binge drinking in\u00a0other research<\/a>.<\/p>\n

Regular nighttime tweeters (23:00 to 05:00) consistently reported worse mental wellbeing than those posting primarily during daylight hours.<\/p>\n

We also looked at how posting times related to symptoms of depression and anxiety. While mental wellbeing captures the positive side of mental health, depression and anxiety reflect specific problems that can undermine it. The links between posting time and these symptoms were weaker overall, but they varied by age and sex.<\/p>\n

For example, the relationship between posting time and anxiety was about twice as strong in older participants, with posting time explaining 1.3% of the differences in anxiety levels among older users compared with 0.6% among younger ones.<\/p>\n

Critical questions remain. Are we witnessing the harmful consequences of late-night posting, or do people with worse mental health gravitate toward nighttime social media use? Do these patterns translate to other platforms or different demographics, particularly adolescents and children? If nighttime social media use genuinely harms mental health, then targeted solutions could be valuable.<\/p>\n

TikTok recently launched\u00a0\u201cwind down\u201d<\/a>, which replaces the homepage for under-16s with calming music and breathing exercises after 10pm. And in the UK, the government is now\u00a0considering legislation<\/a>\u00a0to restrict multiple platforms after 10pm for this age group.<\/p>\n

Nighttime use demonstrates how policy and platforms can address potentially harmful behaviour without resorting to outright bans. It represents a shift away from crude measurements of screen time<\/a> toward considering what people do, when and where they do it, and who they are. This approach moves us beyond simple measurements, toward a better understanding of how our digital lives affect our mental health.\u00a0DM<\/strong><\/p>\n
