The research was conducted with the purpose to study the spiritual behaviour and sleeping behaviour among diabetics and non-diabetics. It was hypothesized that non-diabetics spend more time on spiritual activity and have healthier sleeping behaviour than diabetics. The sample consisted of 200 diabetics and non-diabetics in the age range of 40-60 years. The data was collected with the help of self-constructed questionnaire. t test was applied to study the significance of difference between the spiritual behaviour and sleeping behaviour of diabetics and non-diabetics. Results showed that mean score for spiritual activity behaviour is 5.27 and 20.28 for diabetics and non diabetics respectively. Similarly, for sleeping behaviour mean score is 3.64 and 3.24 for diabetics and non diabetics respectively. t value for spiritual behaviour is 3.96 which is significant at .01 level and for physical activity behaviour, t value is 4.97 which is also significant at .01 level. Results revealed that non-diabetics spend more time on spiritual behaviour and have healthier sleeping behaviour than diabetics. Therefore, it can be concluded that healthy sleeping behaviour and high spiritual behaviour, which leads to better well being, diminishes chances of occurrence of diabetes.
