In an individual's life, especially for students, sleep is an important factor that can specifically affect their well-being and the ability to perform tasks. The quality of their sleep can affect their academic performance and well-being in different ways, either in positive or negative aspects. Many studies have already discussed the correlation between sleep quality to the academic performance and well-being of students. Zhai et al. (2018) found that having normal sleep quality is associated with lower levels of mental problems. Poor sleep quality is associated with a high level of negative mental health. While with academic performance, Ismail (2019) found that students who have good sleep quality have better school performance. However, Jalali et al. (2020) found that there is no significant difference betweenin sleep quality onbetween achieved and unachieved academic performance.

Those who are currently enrolled in the STEM strand are experiencing a higher level of learning, which increases the pressure they feel. Some students sacrifice their sleep and well-being just to excel in class. According to Wang et al. (2020), poor sleep quality was a predictor of learning burnout, and a low sense of achievement. These conditions that can affect the academic performance and well-being of a student can serve as the critical background of this study. Many studies on sleep quality have been conducted both locally and globally, but there is still a lack of how sleep quality will affect both academic performance and well-being of students, particularly senior high school STEM students. This study addresses a research need and can develop plans to help students improve their sleep quality. Dokuka and Smirnov (2020), argue that the relationship between academic performance and sleep patterns can be more complicated than previously believed and that high performance may be achieved at the expense of individual well-being.

Addressing sleep problems is important as it can affect not just the academic performance of students but their well-being as well, especially those who are pursuing the STEM strand. According to Alhusseini et al. (2022), having enough sleep is very important for medical students' general health and psychological well-being. Sleep disorders, irregular sleep habits such as increased screen time before going to sleep, heavy workload, and hectic schedules disturb students' sleep-wake cycles hectic schedulescycles, leading to poor sleep quality. Greater subjective well-being has a relationship with higher academic performance; it is an important aspect of a student’s academic life (Chattu et al., 2020).

Lack of sleep can impair students' well-being and how they take part in class. Teens should have at least 8 to 10 hours of sleep per night so that they can stay focused and improve their concentration and academic performance (Centers for Disease Control and Prevention, 2023). Sleep-related problems are widespread issues, which have not been given enough attention and no effective solution has been created yet. Thus, the aim of this study is to assess if there's a correlation between sleep quality, academic performance, and well-being of senior high school STEM students at AISAT College Dasmariñas, Inc.
