{"abstract":"This research explored the interaction between sleep quality, level of stress, and academic performance in a public secondary school in Gumaca, Quezon. It sought to determine the degree to which sleep habits and stress states affect the academic performance of the students. The descriptive-correlational research design was employed, with a guide questionnaire as the main data collection tool. The survey respondents were 80 senior high school students, who were sampled using stratified sampling. The outcomes indicated that most students experienced poor sleeping habits, mostly attributable to electronic media exposure prior to bedtime, and reported feeling tired most of the time during the day. About stress, students would often report feeling stressed for reasons of academic deadlines, workload, and mental fatigue. With enough time to cope, most students felt that they were not academically performing optimally. Statistical testing by Spearman's rho correlation concluded that there is a significant correlation between sleep quality and stress, as well as between academic performance and sleep quality. Also, from the data, it was concluded that greater stress is linked with lower grades. According to these results, schools should integrate sleep hygiene and stress management interventions to support students' capacity to improve their well-being and academic achievement. A longitudinal study design would strengthen future research by examining more thoroughly the long-term impact of inadequate sleep and chronic stress on students' academic performance.","abstract_source":"original","authors":["Charlene Gonzales","Maria Celerina Oreta","Melchor Espiritu"],"date":"2026-04-15","doi":"10.70838/pemj.550210","id":7625,"issue":2,"journal":{"issn":"2822-4353","name":"Psychology and Education: A Multidisciplinary Journal"},"pdf_sha256":"3dfc232aa6e6f983cf33af3b6d38cca67b0f15120c48fb65cfbc2c4dca0e9d29","schema":"scimatic-article/1","title":"Relationship Between Sleep Quality, Level of Stress, and Academic Performance of Learners in a Public Secondary School in Gumaca","volume":55}
