Can I take sleeping pills on the evening of the second day of the exam?
Generally, if you have an exam the next day, you should not take sleeping pills the night before, as the use of such medication must follow a doctor's instructions. The analysis is as follows:

Sleeping pills primarily help people fall asleep by inhibiting the central nervous system. While they can be effective for short-term insomnia, they may also cause various side effects, such as drowsiness, fatigue, dizziness, and others. These side effects could directly impair performance during the next day’s exam, making it difficult for test-takers to concentrate or even leading to memory impairment. The effectiveness and duration of action of sleeping pills vary depending on the individual and the specific type of medication. Some sleeping pills may leave individuals feeling groggy the following morning, which could negatively affect exam performance.
Therefore, to ensure optimal condition for the exam, it is advisable to avoid taking sleeping pills the night before. Candidates can improve sleep quality through regular sleep schedules, relaxation techniques, and maintaining healthy dietary habits. If sleep problems persist, it is recommended to consult a doctor for proper evaluation and treatment.
