Most parents of teenagers hear the same three things on repeat. More sleep. Better food. More movement. For many families, that already feels like a full-time job.
A new Australian study says the list is incomplete. Researchers who followed teens for up to five years found two other everyday factors, social connectedness and mindfulness, were tied to lower psychological distress and better wellbeing over time.
The paper was published October 8, 2026 in the Journal of Adolescence. It came out of the Longitudinal Adolescent Brain Study at the University of the Sunshine Coast in Australia.
The team followed adolescents aged 12 to 17 and tracked five everyday factors over time. Sleep, diet, physical activity, social connectedness and mindfulness.

Teens with more of these protective factors reported lower psychological distress and higher wellbeing at later check-ins.
Why social connection stood out
Among the five factors, social connectedness emerged as the strongest predictor of both lower distress and better wellbeing. Mindfulness, meaning how present and engaged a young person felt in daily life, came out as another independent protective factor.
Co-lead author Dr Taliah Prince, a youth mental health researcher at the university's Thompson Institute, said the finding reframes the familiar advice. The quotes come from the UniSC release carried by Mirage News.
"We often hear about the importance of sleep, diet and exercise, and while these are important, our research suggests there's a bigger picture to consider," Prince said.

The effect held even after researchers accounted for a teen's earlier mental health. In other words, the extra protective factors appeared to add something on top of where a young person started.
What the two extra factors look like day to day
Social connectedness in the study was not about follower counts or group chats. It was about whether a young person felt genuinely connected to the people around them, including family, friends and classmates.
Mindfulness was measured as a day-to-day quality of attention and presence, not a formal practice. Think of a teen who notices how they feel during the day rather than running on autopilot between school and screens.
The researchers also saw that these habits tend to cluster. A teen who sleeps well is also more likely to eat well, move more and feel connected. For parents, one small change in a weak area may lift several at once.

Senior author Professor Daniel Hermens, a professor of youth mental health and neurobiology, framed why the age window matters.
"Adolescence is a period of remarkable brain development, but it's also when many challenges first emerge, making it a critical window for supporting lifelong mental health," Hermens said.
The same research group reported related findings in Frontiers in Psychiatry in 2024. In that smaller group of 12-year-olds, sleep, social connectedness and mindfulness again stood out as the strongest links to lower distress.
In the new paper, social connectedness moved both distress and wellbeing more than any other single factor the researchers tracked.
