This study looks at sleep hygiene-the daily habits and environment that help people sleep well-among 2nd-year students at the Health Services Vocational School of Bilecik Şeyh Edebali University (Türkiye). Many health sciences students have busy schedules, clinical practice, and exam stress, which may reduce sleep quality. Good sleep is important for learning, attention, mood, and overall health. Purpose: The aim is to assess the current sleep hygiene and quality of students, and determine whether a brief, in-person education program can enhance their knowledge, habits, and sleep quality in the upcoming weeks. Who can take part: The program is designed for daytime (normal education) 2nd-year students in programs such as Operating Room Services, Paramedic, Opticianry, Pharmacy Services, Medical Laboratory Techniques, Medical Documentation and Secretariat, and Child Development who volunteer and give written consent. Participation is voluntary, and you may leave the study at any time without any penalty. What will happen if you join: You will complete short forms before the education session to measure sleep habits and sleep quality (for example, bedtime, caffeine use, and screen time). You will attend four classroom sessions (each about 40 minutes). These sessions explain practical sleep tips (regular bed/wake times, reducing evening caffeine and screen time, preparing a quiet/dark room, simple relaxation after clinical shifts) and help you create a personal sleep plan. You will fill out the same forms again 2 weeks and 4 weeks after the education to see changes over time. What we measure: Sleep hygiene behaviors (how often helpful/unhelpful habits are used) Sleep quality refers to how restful sleep feels, the time it takes to fall asleep, the frequency of night awakenings, and overall daytime functioning. Knowledge about sleep hygiene (a short quiz) We will also look at factors like stress level, evening screen use, and caffeine intake. Possible benefits: You may learn practical ways to improve sleep, which can help with attention, mood, and daily performance. Possible risks/discomforts: This is an educational program. Risks are minimal (for example, brief discomfort when answering personal questions about sleep). You can skip any question you do not want to answer. Privacy: All information will be kept confidential and used only for research. Reports will not include names or identifying details. Costs and payment: There is no cost to taking part, and there is no payment for participation. Withdrawal: Participation is voluntary. You may stop at any time without affecting your courses or grades.
