Adolescence period is the most important stage of a human being and it is the stage between childhood and adulthood. Adolescence is a time of storm and stress. They cannot adjust to their new role in life. They can have mental, emotional, adjustment, and behavioural problems known as "disorders". Behavioural patterns that emerge in adolescence include smoking, consuming alcohol, other substance use, violence, sexual behaviour, etc. An individual experiences satisfaction when his physiological and psychological needs are fulfilled. Failure of satisfying the needs makes him/her depressed and disappointed. Anxiety disorders, depression, stress, risky sexual behaviours, violence, aggressive behaviour, and disobedience are some behavioural disorders of adolescent students. During adolescence, an adolescent is unable to adjust with parents, school discipline, and the community. He/she is confused with the role of adolescence with regard to somatic variation and problems. These problems greatly affect the academic performance of the adolescent students at school. The main aim of this paper is to discuss the fact that behavioural and adjustment problems can be reduced by Yoga. Yogasana, Pranayama, and Meditation are the techniques given to the Adolescent students as a solution to their problems. The purpose of this paper is to give an insight of Yoga and how Yoga helps the adolescents to lower their stress and stay calm. The result of Yoga intervention to adolescent students has positive effects on both physical and mental health. It benefits the young people not only in school, home, and the community but also throughout their life.
