At 13 years old, most adolescents experience significant physical and hormonal changes as they enter puberty. This includes growth spurts, changes in body composition, and the development of secondary sexual characteristics, such as breast development in girls and increased muscle mass in boys. Mood swings and heightened emotions are also common due to fluctuating hormone levels. Additionally, cognitive development advances, leading to improved reasoning and decision-making skills.
