Helping teenagers feel happier and more emotionally resilient involves more than encouraging nutritious meals, regular exercise and sufficient sleep. New Australian research suggests that friendships, social connections and mindfulness also play important roles in adolescent mental health.

Researchers at the University of the Sunshine Coast found that young people with several positive lifestyle and social factors were more likely to report better wellbeing and lower psychological distress over time.

The findings, published in the Journal of Adolescence in October 2026, highlight the value of supporting different aspects of teenagers' everyday lives.

What The New Research Discovered

Scientists from the university's Thompson Institute examined information collected through the Longitudinal Adolescent Brain Study. The project followed teenagers aged 12 to 17 for up to five years, recording lifestyle habits, emotional wellbeing, cognitive performance and brain development. Researchers investigated how various protective factors were associated with mental health at later assessments. These included sleep, nutrition, physical activity, social connectedness and mindfulness. Teenagers with more protective factors generally reported better emotional wellbeing and fewer symptoms of psychological distress. Importantly, the relationship remained evident even after researchers considered participants' earlier mental health.

Why Healthy Habits Are Only Part Of The Picture

Getting enough sleep, eating nutritious foods and remaining physically active are widely recognised as important for healthy development.

However, the new findings suggest that focusing exclusively on these habits may overlook other meaningful influences. Feeling accepted by friends, maintaining supportive relationships and participating in enjoyable activities can contribute to a teenager's sense of security and belonging.

Mindfulness, which involves paying attention to present experiences, may also support emotional awareness. These different factors can work alongside one another, creating a more supportive environment for young people.

Friendships May Make A Difference

Adolescence is a period of major social change, when friendships and personal relationships become increasingly important. Feeling connected to others may help teenagers navigate academic pressure, uncertainty and everyday challenges. Researchers found that protective lifestyle behaviours and social strengths frequently occurred together.

For example, young people with positive habits in one area were often more likely to report strengths in others. However, the study did not establish that strong friendships directly prevent mental health difficulties.

Why Mindfulness Deserves Attention

Mindfulness encourages people to notice their thoughts, feelings and surroundings without immediately reacting to them. For teenagers, this might involve concentrating on breathing, taking a quiet walk or paying closer attention to ordinary experiences.

Such practices may provide opportunities to recognise emotions and respond more thoughtfully to stress. However, mindfulness should be considered one possible source of support rather than a guaranteed solution to psychological difficulties.

What Parents And Schools Can Do

The findings suggest that supporting adolescent wellbeing requires a broad approach. Families can encourage regular routines while creating opportunities for open conversations and meaningful social interaction.

Schools may also contribute by providing welcoming environments, encouraging positive peer relationships and helping students develop emotional awareness. Young people experiencing persistent distress may require additional support from qualified professionals.

Why The Findings Matter

Adolescence is an important period of brain development, during which emotional and behavioural patterns continue to evolve. The study was observational, so it cannot prove that adding specific habits will directly improve mental health.

Nevertheless, it suggests that wellbeing is associated with a combination of everyday behaviours and supportive relationships. Helping teenagers thrive may therefore involve looking beyond physical health to the social and emotional experiences shaping their daily lives.
