O b jectives: 1) To Find the effectiveness of BME on sleep quality, health promoting life style factors and knowledge in interventional group. 2) To compare the post test sleep quality, health promoting life style factors and knowledge scores between experimental and control group Methods: A Quasi experiment al study with a sample of 180 nursing staffs was selected by Purposive sampling Technique 90 samples in each group. The data was collected by using Pittsburgh sleep quality index Scale , health promoting life style profile II, structured knowledge questionnaire was used. Results: The Wilcoxon signed ranks test value is 7.719, p <0.001 it shows there is a significant difference between pre test knowledge scores and post test knowledge scores in experimental group. The significant difference were fou nd in pre test and post test of life style profile by Wilcoxon Signed Ranks Test.(Spiritual growth 4.032, p<0.001, Health responsibility 5.288, p<0.001, physical activity 6.934, p<0.001, Nutrition 6.212, p<0.001, Interpersonal relations 5.706, p<0.001, str ess management 7.018, p< 0.001, overall 6.766, p<0.001) in experimental group. There is a post test significant difference between all factors of health promoting life style factors between experimental group and control group of nursing personal. The sign ificant difference were found by Mann whitney U test (Spiritual growth 3012.000, p<0.001, Health responsibility 2062.500, p<0.001, physical activity 1522.500, p<0.001, Nutrition 2377.500, p<0.001, Interpersonal relations 3241.500, p<0.001, stress managemen t 1878.500, p< 0.001, overall 1928.500, p<0.001). 0.001).). The significant difference P value of all factors are less than 0.05 level of significance. There is significant difference between pre test and post test sleep quality index scores found by Wilcoxon Signed Ranks Test namely in the area like (sleep latency 6.006, p<0.001, sleep duration 4.145, p<0.001, sleep efficiency 2.493, p<0.013, sleep disturbance 5.539, p<0.001, use of sleep medication 2.788, p<0.005) in experimental group. There is sign ificant difference between post test sleep quality index scores found by Mann Whitney’s U Test namely in the area like (sleep latency 2429.000, p<0.001, slee p duration 2427.500, p<0.001, sleep disturbance 2183.000, p<0.001, use of sleep medication 2.788, p <0.005) between experimental group and control group. Conclusion: BME is effective intervention for enhancing sleep quality, knowledge and health promoting life style factor among staff nurses. So the intervention can be conducted for prolonged period of time to know its effect
