This type of research is descriptive quantitative using a cross-sectional approach with 100 respondents. Data collection used a questionnaire. Data analysis test used Spearman Rho. The results of univariate analysis, the most insomnia is mild insomnia as many as 53 students with a percentage (53%). The most students with a moderate level of learning concentration are 67 students with a percentage (67%). The most data respondents with female gender as many as 84 with a percentage (84%). The age of the most respondents is 20 years as many as 57 students with a percentage (57%). The results of bivariate analysis with Spearman rho obtained significant results between insomnia and the level of learning concentration of 0.000, the value is <0.005 with a moderate relationship as evidenced by the r value of 0.469.

College represents a critical transitional period requiring high adaptation, where students often face escalating academic demands triggering psychological pressure. This study aims to deeply analyze the reciprocal relationship between sleep patterns and academic stress levels, and identify their subsequent impacts on cognitive function (concentration) and students' physical health. This study employs a qualitative method with a Systematic Literature Review approach. Data were collected through comprehensive searches of accredited national and reputable international scientific articles published within the last five years (2020–2025). Literature selection was conducted rigorously using specific keywords to screen empirical studies relevant to stress, sleep, and student health variables. Data synthesis reveals a strong and consistent negative correlation. High levels of academic stress whether stemming from the adaptation phase of new students (initiation), thesis preparation workload, or role conflicts in working students are significantly associated with decreased sleep quality. Physiologically, stress triggers increased cortisol levels causing insomnia, shortened sleep duration, and prolonged sleep latency. Subsequent impacts are proven to drastically reduce learning concentration and trigger physical health disorders, including an increased risk of primary dysmenorrhea in female students. This study concludes that academic stress and sleep disturbances form a destructive cycle that exacerbates one another. Therefore, holistic institutional interventions in the form of sleep hygiene education and stress management training are needed to break this chain for the sake of student well-being and academic performance.

The increasing use of gadgets among medical students raises concerns about the health impacts, especially on sleep quality and eye health. Medical students have a high intensity of digital device use due to academic demands, which has the potential to cause excessive exposure to blue light (blue light), sleep disturbances, and eye fatigue (eye strain). This study aims to explore the relationship between the duration of gadget use with sleep quality and eye strain in medical students and to understand the factors that strengthen or weaken its impact. The research method used is qualitative descriptive based on a literature study by reviewing literature from scientific journals, books, and relevant documents. The results of the study showed that exposure to blue light can reduce melatonin production, disrupt circadian rhythms, and cause sleep disorders such as insomnia. In addition, long-term use of gadgets without sufficient rest increases the risk of digital eye strain, characterized by symptoms such as dry eyes, blurring, pain, and headaches. Medical students who are susceptible to intensive exposure to digital screens are at higher risk of this disorder. In conclusion, there is a strong interconnection between gadget use, sleep quality, and eye fatigue. Preventive efforts such as screen time management, use of blue light filters, and education about healthy visual habits are important to maintain the health and productivity of medical students.
