Adolescence is a critical phase marked by rapid development, making lifestyle choices during this period pivotal for long-term well-being. This study explores the knowledge and awareness of physical activity and yoga among school-going adolescents in Himachal Pradesh, India, given the increasing concerns about sedentary behaviors and lifestyle changes in this picturesque northern state. Material & Methods: A cross-sectional survey was conducted across Himachal Pradesh from April to July 2023, involving 400 school-going adolescents. A questionnaire assessed knowledge about physical activity and yoga. Data analysis was conducted using Epi Info V7 Software, and ethical considerations were followed to maintain confidentiality and anonymity. Results: The study revealed that while a significant proportion of adolescents demonstrated a good understanding of the benefits of physical activity, including reducing health risks and stress management, gaps existed in knowledge regarding recommended daily activity levels. Additionally, participants displayed a moderate level of awareness of yoga's benefits, particularly its impact on mental well-being. Conclusion: The study underscores the importance of enhancing awareness regarding the recommended daily physical activity levels among adolescents in Himachal Pradesh. Targeted educational interventions can bridge these knowledge gaps, promoting healthier lifestyles and overall well-being.
