Teenage development refers to the physical, emotional, and social changes that occur during the teenage years, typically between ages 13 and 19. During this period, individuals experience significant growth spurts, hormonal changes, and the onset of puberty, which can affect their physical appearance and health. Emotionally, teenagers often seek independence and identity, leading to shifts in relationships with family and peers. They may experience heightened emotions and develop critical thinking skills, which can influence their decision-making and social interactions. Understanding these changes is essential for supporting healthy development during this crucial stage of life.
