The complexity of the healthcare courses gives more academic pressure. The pandemic had significantly affected health, the educational system, and students’ habits. The pre-pandemic studies reported more sleep problems among healthcare students. So this study is essential to identify the current status of insomnia among students. Aim: The major aim of this study was to identify the prevalence and severity of insomnia among healthcare students after the COVID-19 pandemic and to examine the association between insomnia and selected variables. Materials and methods: This cross-sectional web-based survey was conducted among 300 healthcare students at the University of Tabuk, Saudi Arabia. Students were surveyed using the Insomnia Severity Index (ISI) to identify the prevalence of insomnia. Results: The prevalence of insomnia among healthcare students is as follows: No insomnia (17.33%), subthreshold insomnia (49.33%), moderate insomnia (31.33%), and severe clinical insomnia (2%). The mean score on the ISI was 12.37±4.77. 77% of the students reported that academic load affected their sleep patterns. The usage of social media and online games at night was high among students. Participants’ age, sleep hours, quality of sleep, academic load, drinking coffee or tea before bedtime, snoring, medical problems, smoking, and usage of social media & online games at night had a significant effect on the sleep pattern. Conclusions: The results of this study emphasized the necessity of sleep education and sleep hygiene among medical students. There is an urgent need for further studies to focus on health status and sleep disturbance, sleep patterns and learning capabilities, and interventional studies to improve sleep patterns. Enhancing sleep self-awareness among medical students is necessary for managing this issue.
