Sleep deprivation is noted as one of the prevalent causes of disrupted circadian rhythms, especially for students and young adults. From a local perspective, around 46% of Filipinos do not get adequate sleep, and 32% stated that they get less than six hours of sleep per day (National Nutrition Council, 2021). A survey from Sleep Cycle found that Filipinos spent between 6 hours and 30 minutes and 6 hours and 45 minutes of sleep on average. This study discussed how the sleep quality and task workload of undergraduate and graduate students taking up different courses offered by the University of Santo Tomas affected their academic performance during the COVID-19 pandemic. The study measured the seven components of sleep quality using the Pittsburgh Sleep Quality Index (PSQI), the five components of task workload through the NASA Task Load Index (NASATLX), and the age, gender, and year level of the respondents. The academic performance of the respondents was measured through their General Weighted Average (GWA) for two academic years. The correlation among the variables was then determined using the multiple linear regression analysis. After a thorough analysis of the results, it was concluded that age was a significant factor that affected the academic performance of graduate and undergraduate students.Sleep deprivation is noted as one of the prevalent causes of disrupted circadian rhythms, especially to students and young adults.
