Tenårene

Tenårene refers to the period of adolescence, roughly from about 10 to 19 years old, bridging childhood and adulthood. It is marked by rapid physical, cognitive and social changes, with variation in pace and duration among individuals and societies.

Physically, puberty brings growth spurts and sexual maturation driven by hormones. Secondary sexual characteristics develop, body composition changes, and timing varies between individuals and between genders. These changes culminate in greater adult physical proportions and capabilities, though full maturation may continue into the late teens.

Cognitively and emotionally, the brain continues to mature during this period, influencing planning, decision-making and emotion regulation. Teens form identities, seek greater autonomy, and increasingly engage in abstract thought. Mood fluctuations and heightened sensitivity to peer influence are common, and mental health concerns such as anxiety or depression can emerge.

Socially, relationships with family, peers and romantic partners become central. Education, career planning and sexual health education influence development. Digital media and online communities shape communication and access to information, offering opportunities for growth as well as risks related to privacy, cyberbullying and misinformation.

Health and well-being emphasize the importance of sleep, nutrition and regular physical activity. Preventive health care, vaccinations and safe behaviors support healthy development. Risk factors during tenårene can include substance use, injuries and unsafe sexual practices. The period is also shaped by cultural, legal and policy contexts that define rights, responsibilities and protections for young people.
