Puberty is a period of major physical and psychological changes experienced by adolescents and young adults during the transition from childhood to adulthood. It is marked by hormonal changes that cause the development of secondary sexual characteristics, such as increased body hair, voice deepening, and the development of breasts and genitalia in females. During this time, adolescents also experience changes in cognitive development, such as increased capacity for abstract thinking, and emotional development, such as increased independence from parents. These changes are essential for the transition to adulthood, and can be challenging for both adolescents and their families. It is important to be aware of these changes and provide guidance and support to adolescents as they undergo this transition.
