Abstract The aim of this study is to get awareness about the benefits of physical activity and its effect on dental students. Recently, it has been recognized that lack of physical activity , especially regular stretching of arms and legs, may affect the course and pathogenesis of a number of systemic diseases such as cardiovascular disease, bacterial pneumonia, diabetes mellitus and low birth weight. The purpose of this study is to get awareness about the importance of physical activities and their benefits during the busy schedule of dental students. Dentistry is a field of challenges, especially the health of a budding dentist must be on top priority . A well maintained body is equal to a peaceful mind and it can be attained only through exercise. A cross sectional questionnaire survey was conducted. A total of 104 people of Saveetha Dental College were made to answer all the questions. The result will be analyzed using statistical analysis. In this study, it was found that 90% are aware of the effect of physical activity to control systemic disease and only 14% are not aware of the statement. It has been proven that physically active individuals gain less weight over time and maintain good health. Thus infrastructure improvements such as sports activity in colleges among faculties, combined with regular exercise provide additional physical activity that would help to reduce obesity and non-communicable diseases in the future.
