Yoga is a practical philosophy that involves every aspect of a person's being: physical, psychological and spiritual. Yoga-based interventions have been found to have diverse effects including diminished stress and improved concentration. Past research revealed connections between yoga and stress reduction, as well as between yoga and academic achievement, when yoga was done outside the classroom. This study evaluated the effects of doing yoga for eight standard students on nutritional and academic achievement. The results indicate that yoga in the classroom was a positive addition to the classroom schedule. The results indicate that, students showed an increase in nutritional parameters, performed better on Numerical ability, Verbal ability, World relationship test, Reading ability and Writing ability test, and perceived a benefit of doing yoga. These results suggest that yoga is a positive addition to the secondary school students and can be an effective way to help students cope with stress and focus on schoolwork.
