ABSTRACT
Background and Aims : Sleep is a highly conserved behaviour across animal evolution. The functions of sleep include restoration, memory processing, dreaming etc. Memory is informational processing system with explicit and implicit functioning made up of sensory processor, short term memory and long term memory. The present study was designed to analyse the impact of sleep quality on memory and effect of exercise and meditation on same. Material and Method : The present study was performed on 110 subjects chosen randomly with no gender bias. In first phase, baseline values were assessed for different sub tests of sleep quality and different aspects of memory. Subjects were divided into two groups with each group including 27 males and 27 females. One group was required to perform moderate intensity exercise and other meditation for one month duration. In the second phase, parameters were again assessed. Statistical analysis : Paired t-test was used for comparison of memory and sleep components between males and females. Independent t-test was used between baseline and post intervention values of exercise, meditation. Correlation studies were also carried out between sleep quality and different aspects of memory using Pearson correlation coefficient. Result : Significant and non significant results were obtained on comparison of memory and sleep components in males and females. Total memory score was better in females. Exercise and meditation exhibited statistically significant result on memory and sleep quality. Conclusion : Good sleep quality is associated with better memory. There is improvement across domains of memory and sleep with meditation and exercise.
