How Lifestyle Choices Impact Teen Mental Health

SpainMon Nov 10 2025

Teenagers today face a lot of pressure. They juggle school, friends, and growing up. But did you know their daily habits can greatly affect their mental health? A recent study looked at how lifestyle choices relate to non-suicidal self-injury (NSSI) in Spanish teens.

The Study

The study focused on students aged 14 to 16. Researchers checked various aspects of their lives. These included:

  • Eating habits
  • Exercise
  • Screen time
  • Substance use
  • Risky behaviors
  • Sleep quality

They also asked about NSSI.

Key Findings

The findings were clear:

  • Teens who exercised regularly, limited screen time, and got good sleep were less likely to harm themselves.
  • Risky behaviors, like unsafe sex or excessive screen use, showed a link to higher rates of NSSI.
  • Interestingly, spending time with friends did not show a strong connection to NSSI.

Lifestyle Score

The study also created a lifestyle score. Teens with healthier habits had a 71% lower chance of engaging in NSSI. This held true for both boys and girls. The results suggest that promoting healthy lifestyles could help reduce self-injury in teens.

Why Does This Happen?

Experts believe that healthy habits boost self-esteem and coping skills. On the other hand, risky behaviors may lead to feelings of shame or guilt. These negative feelings can trigger self-harm.

The Importance of Education

The study highlights the importance of education. Teaching teens about healthy lifestyles could be a powerful tool. It might not only improve their physical health but also their mental well-being.
