More Daily Steps Linked to Better Mental Health and Brain Structure in Teens
- •A study published in JAMA Network Open found that taking more daily steps at ages 11 and 12 was linked to fewer mental health problems a year later.
- •The benefits continued up to 12,000 or more steps a day with no sign of levelling off, showing that every extra step counts.
- •Teens with higher step counts displayed differences in brain regions linked to movement and mood, explaining the link to better mental health.
- •Increments of 1,000 to 2,000 daily steps from any starting point were associated with improved brain structure and mental health outcomes.
- •Researchers tracked 5,515 adolescents using Fitbit devices and questionnaires to measure symptoms like anxiety and low mood.
Key Questions Answered
Research shows that taking more daily steps at ages 11 and 12 is linked to fewer mental health problems like anxiety and low mood a year later. The benefits continue up to 12,000 or more steps a day without levelling off.
Teens with the highest step counts showed slightly thicker brain tissue in two areas involved in movement and emotion regulation. These structural differences helped explain the link between physical activity and better mental health outcomes.
There is no strict threshold or all-or-nothing situation, as teens taking under 5,000 steps had the most symptoms, those at 8,000 had fewer, and those hitting 12,000 or more had the fewest. An increment of 1,000 to 2,000 steps from any starting point helps improve outcomes.
