Résumé
Background: It is often seen that college students struggle to get enough sleep whether it is due to studies or their lifestyle. This affects their sleep habits, making it overwhelmingly negative. This inconsistent sleep patterns, lack of efficient sleep, late bed times and other sleep related problems negatively affect quality of life. Objective:In this we tried to report the effect of sleep quality on student's cognitive performance and handgrip strength. Methods: 73 healthy female students were assessed using the Pittsburgh Sleep Quality Index (PSQI). On basis of PSQI out of 73 students, there were 29 good sleepers and 44 poor sleepers. Their hand grip strength and visual reaction time was measured. Statistical analysis was performed using R software (v. 3.2.5). Pvalue was considered to be significant at (p<0.05). Results: On the basis of data analysis, it was found that good sleepers have significantly higher cognitive functions than poor sleepers. Their hand grip strength was not found significant in comparison with good and poor sleepers. Conclusion:We may conclude that, quality of sleep does have positive correlation with cognitive changes.
