ABSTRACT: Youngsters in their teens represent the world's largest age demographic, in a special period known worldwide as the bridge between childhood and maturity in the life cycle. Longitudinal surveys and accurate assessments of teenage activity in both developed and emerging countries are providing new perspectives. Throughout adolescence, physical and psychosocial shifts cause incarnate challenges of centuries and early childhood to appear in human differences in areas such as maturity, academic achievement, self-confidence, peer pressure, and family proximity. The wellbeing and well-being threats to parents are therefore foreseen. Multi-disciplinary methodologies, in particular biological-social science, socio-economic and cultural variability and determinants of positive results needed to raise understanding at that stage. Depression, anxiety, and eating disorders are especially common during the days of the puberty. Adolescents with anxiety or mood disorders may suffer from physical symptoms such as exhaustion or chronic fatigue, dizziness, headache and pain in the abdomen or arms. The five main features of puberty are biological growth and development, an unclear status, increased decision-making, increased anxiety, and self-search. Adolescence is a lifetime with specific needs and rights relating to health and development. It is also a time to develop awareness and skills, learn to control feelings and relationships, and gain qualities and skills that would be necessary for teenage years to be experienced and adult positions to take on.
