Religious bells also served to mark the passage of time throughout the day before people wore watches. In many early Christian societies, bells called churchgoers to prayer in the morning. Later versions turned gears, signaling an alarm or even springing a catapult that launched a pellet into a metallic plate. Making the clepsydra an alarm clock required nothing more than a floating bob that struck an alarm once it reached a desired level. It's mind-boggling to think about what Ctesibius accomplished: Seasonal cycles required irregular water levels be dispensed into a receiving vessel with equidistant hour-marks, while daily cycles required varying hour-marks and regular efflux. It wasn't until 245 BCE that Ctesibius of Alexandria improved the clepsydra, or "water thief" as it was known, and created the world's first mechanical clock. They weren't so much clocks as they were timers, working in much the same way a common hourglass works. Speaking of water, the clepsydra, or water clock, was used by the earliest civilizations for thousands of years. The custom of "over-drinking" before bed was even utilized by Native Americans well into the 20th century. Why? Well, if you're over the age of 30 or so, you probably know what getting up in the middle of the night to urinate is all about. BLADDER CONTROLĮarly man drank tons and tons of water if he needed to wake up before the sun. Here are seven ways people would wake up before the invention of the modern alarm clock. After all, there’s no snooze button for church bells or a factory whistle. Though no matter how much you’ve grown to despise the incessant beeping of your alarm, know that waking up was no less of a struggle for previous generations. They’re necessary for keeping appointments and staying employed, but you won’t find many people that actually enjoy being jolted out of bed to the same tone every morning for years on end. We have complicated relationships with our alarm clocks.
