New research shows small lifestyle changes are linked to differences in teen mental health over time

Mental health among teenagers has been a growing concern in recent years, with recent headlines and policy ideas suggesting that screen time is the primary culprit. However, our research suggests that there are many other lifestyle behaviors that can have a significant impact on teen wellbeing.

Lifestyle factors and mental health in teenagers

Our research tracked over 4,400 Australian high school students from 71 schools across New South Wales, Queensland, and Western Australia. We looked at a range of lifestyle behaviors, including sleep, physical activity, screen time, fruit and vegetable intake, junk food consumption, and alcohol use. We found that improvements in these behaviors were associated with small but significant improvements in mental health.

Conversely, increases in unhealthy behaviors were linked to higher levels of psychological distress. For example, every additional hour of screen time per day was linked to a 2% increase in psychological distress.

The impact of small lifestyle changes

Our study found that even small changes to lifestyle behaviors can have a significant impact on mental health. For example, every additional hour of sleep per night was linked to a 9% reduction in psychological distress. Each additional daily serve of fruit or vegetables was linked to a 4% reduction in psychological distress.

Similarly, small increases in physical activity, such as an additional 30 minutes per week, were linked to a 3% reduction in psychological distress.

The benefits of a healthy lifestyle

Our research suggests that a healthy lifestyle can have a significant impact on mental health. This is because a healthy lifestyle can improve overall wellbeing, increase self-esteem, and reduce stress.

Additionally, a healthy lifestyle can also provide young people with the skills and resources they need to manage their mental health. For example, healthy sleep habits, a balanced diet, and regular exercise can all help to reduce stress and improve mood.

What can parents and teenagers do?

Our research suggests that parents and teenagers can play a major role in shaping lifestyle behaviors. This can involve making small changes to daily routines, such as getting an extra hour of sleep per night or eating one extra serve of fruit or vegetables per day.

Parents can also play a key role in modeling healthy lifestyle behaviors. For example, they can make healthy food choices, get regular exercise, and practice good sleep habits. They can also help teenagers to develop healthy relationships with technology, such as setting limits on screen time and encouraging outdoor activities.

The bigger picture

While lifestyle behaviors are an important factor in determining mental health, they are just one piece of the puzzle. There are many other factors that can influence mental health, including socioeconomic status, social relationships, and access to healthcare.

It is important to recognize that mental health is complex and multifaceted, and that no single factor is solely responsible for an individual’s mental wellbeing. Instead, mental health is influenced by a range of factors that interact with one another in complex ways.

Conclusion

In conclusion, our research suggests that small lifestyle changes can have a significant impact on mental health in teenagers. By making small changes to daily routines, such as getting an extra hour of sleep per night or eating one extra serve of fruit or vegetables per day, young people can improve their mental wellbeing.

We hope that our research will inform public health policies and programs that promote healthy lifestyle behaviors among teenagers. By working together, we can create a society that supports the mental health and wellbeing of young people.
