Helps Kids Stay Active and Healthy

At an early age, it’s important to help kids build the foundation for a healthy lifestyle. That means developing healthy eating and exercise habits that will carry them through life. The team at AdventHealth Ottawa believes that staying active is important for the development of a healthy heart, lungs and mind, and keeps muscles and bones strong.

Here are a few reasons why it’s important to help kids become and stay active:

  • Active children are more likely to become active adults
  • More physical activity in children is associated with higher test scores in reading and math
  • Regular exercise promotes self-efficacy with regard to health and self-image
