Understanding Sleep Hygiene

Sleep hygiene is the set of daily habits, routines, and environmental choices that support consistent, restorative sleep. In this lesson, Professor Peter Lambert explains what sleep hygiene is, why it matters, and how it influences sleep quality without replacing medical treatment when a sleep disorder is present.

You will learn the difference between useful habits and common myths, how sleep pressure and body clock timing shape rest, and why a practical approach works better than chasing one perfect bedtime rule. This foundation prepares you to build realistic sleep routines in the next lessons.
