睡眠衛生（Sleep hygiene）是指一系列有助於改善睡眠品質的行為習慣。咖啡因（Caffeine）是一種中樞神經興奮劑，其半衰期長，下午飲用會抑制腺苷（Adenosine）受體，導致入睡困難或睡眠中斷。良好的睡眠衛生應包含規律的作息、舒適的睡眠環境（黑暗、安靜、涼爽）以及避免睡前刺激物。臨床評估時，護理師應詢問病人睡前習慣，並提供衛教以改善失眠問題。
Caffeine is a central nervous system stimulant with a long half-life that can block adenosine receptors, making it difficult to fall asleep or stay asleep. Poor sleep hygiene includes consuming stimulants close to bedtime, whereas consistent routines, light snacks, and a dark, quiet environment promote rest.
