Practice Kindness

We know children’s mental health benefits from positive social connections. We also know that the opposite is true; children who experience bullying, exclusion and isolation are at risk for mental health concerns.

This is why encouraging kindness can be so important for children’s mental health. Kindness can help kids build empathy, create and maintain healthy relationships, and help develop a sense of community.

Research shows that kindness toward ourselves and others helps our mental health. It can:

  • Help build friendships
  • Increase feelings of happiness
  • Reduce stress
  • Improve self-esteem

Bonus tip: Make kindness a habit in your family to help with lasting mental health benefits. Start with our 5-day challenge and then come up with ways to keep it going!
