young students to maintain their quality of sleep as well as general performance in their studies.
The body temperature phase of young/adults is found to be little late as compared to elderly people. The peak body temperature is said to be in early morning hours. Moreover there occurs the existence of a "forbidden zone" which coincides with highest body temperature and peak muscle activity.7.8 It is considered that this time zone occurs, in young people, around 5.00-6.00 hours in the morning. Rejuvenating light exercises during this hour is effective for improving the sleep quality in the following rest phase. It is also considered that exercise in the evening or in early morning hours increases the activity of the arousal system in the 'forbidden zone'. It is further considered that meditation may be working through the pathway of reticulating hypothalamic route. Neuronal activity of hypothalamus stabilizes after meditation which results in negative feedback to RAS which results in better quality of sleep, because daytime arousal is regulated. This is well demonstrated in the result of study. This is again substantiated with the increased frequency of nodding. After the 'intervention', mental health had also improved with improving sleep quality, as well as vo physical health. The study's results suggest that this ãinterventionä technique is effective in improving the quality of life and the activity of daily living and routine of young students.
