Every year on April 28th, we observe “Biological Clock Day” to raise awareness about the circadian rhythm and how it impacts our sleep, bodily functions, and emotions. It’s interesting to note that humans used to have segmented sleep, with only six hours of sleep before the invention of the electric lamp. The biological clock is closely related to the circadian rhythm, a 24-hour cycle within our internal clock that regulates important functions like our sleep-wake cycle. These rhythms are controlled by a master clock in the brain, which receives signals from the environment to synchronize our activities with the day-night cycle.

📜 Biological Clock Day History

The concept of segmented sleeping, which involved two distinct sleep cycles with wakeful periods in between, was first mentioned in Homer’s “The Odyssey” during ancient times and continued to be practiced until the Renaissance. During these wakeful periods, people engaged in various activities such as chatting, praying, doing chores, socializing, and even engaging in intimate relationships. This sleeping pattern was highly esteemed during the late Middle Ages and Renaissance. However, with the advent of the Industrial Revolution in the nineteenth century, everything changed. The invention of the incandescent light bulb by Thomas Edison in 1839 led to longer workdays and a shift towards prioritizing work and productivity over obtaining a full night’s sleep. This marked the end of segmented rest.

As working hours increased, movements like the eight-hour movement emerged, advocating for shorter workdays. In 1926, Ford implemented the eight-hour workday and the 40-hour workweek, which became the global standard for corporations. However, in recent times, there is a renewed appreciation for the importance of sleep due to its numerous health benefits and its impact on productivity. Corporate executives, in particular, have recognized the value of sleep and utilize it as a means to enhance their productivity. They take advantage of the time between meetings and business trips to indulge in much-needed naps.
