While the term "sleep hygiene" was first introduced by Nathaniel Kleitman in 1939, the modern concept and practical application of sleep hygiene, as a set of behavioral rules for improved sleep, is largely attributed to psychologist Peter Hauri, particularly through his book published in 1977.
Therefore, the answer isn't as straightforward as a single inventor. It's more of an evolution of an idea.
Here's a breakdown:
- Nathaniel Kleitman: Coined the term "sleep hygiene" in 1939.
- Peter Hauri: Introduced the concept of sleep hygiene as a practical set of behavioral guidelines to improve sleep, solidifying its place in modern sleep medicine with his 1977 publication.
Hauri's contribution was significant because he translated the abstract idea of "sleep hygiene" into a tangible set of recommendations people could follow. These recommendations typically involve things like:
- Maintaining a regular sleep schedule
- Creating a relaxing bedtime routine
- Optimizing the sleep environment (dark, quiet, cool)
- Avoiding caffeine and alcohol before bed
- Getting regular exercise
- Managing stress
So, while Kleitman provided the terminology, Hauri provided the actionable framework that defines sleep hygiene as we understand it today.
