Many health habits that affect well-being later in life begin during childhood and adolescence (teenage years). Childhood is a key time for growth and development, and early experiences can have lifelong effects. Regular checkups and developmental screenings help find health problems early, when treatment works best. Healthy habits like good nutrition, regular physical activity, and enough sleep can prevent illness and injury. Safe, stable, and supportive relationships at home, in schools, and in communities are essential for children’s health and well-being and can improve outcomes over time.
Teens face higher risks for preventable problems, such as substance use and sexually transmitted infections. They also go through physical, emotional, and mental changes that affect their health. Encouraging healthy behaviors—like getting preventive care, avoiding excessive screen time, having regular physical activity, eating a healthy diet, and getting enough sleep—can help teens stay safe and healthy.
The information and data on this page define childhood as ages 2-11 and adolescence as ages 12-18, or youth in grades 9 -12.
