As far as most people are concerned, the sleeping cap is a historical item rather than something that’s relevant to people in need of a few hours’ worth of sleep in the modern era. In some ways, they’re correct. Most people do not need them in today’s world filled with modern conveniences such as central heating and air conditioning. That doesn’t mean, however, that they aren’t at all useful today. Many retailers still sell them today.
The History of the Sleeping Cap
While it’s not exactly known when or, specifically, where the sleeping cap (often referred to as a nightcap, sleep hat, or sleep bonnet) originated, at one time, sleeping caps were worn because fires died down and homes were incredibly cold during the late hours of night or wee hours of morning. Since the thought was a large chunk of a body’s heat escapes through the head, it made perfect sense to keep the head covered in an effort to retain body heat so you can remain warm throughout the night.
