Why You Wake Up at 3 AM Every Night | History of The Watch

For centuries, waking up at 3 AM wasn't insomnia, it was normal. Before the Industrial Revolution and artificial lighting changed everything, humans across Europe and beyond practiced what historians call biphasic sleep: a natural two-phase sleep cycle made up of "first sleep," a wakeful interval known as "the watch," and "second sleep." Sleep historian Roger Ekirch discovered over 500 historical references to this pattern in diaries, medical texts, and legal records spanning a thousand years. In this video, we explore the lost history of segmented sleep, the science behind why you wake up in the middle of the night, and what a landmark experiment by sleep researcher Thomas Wehr revealed about our biological sleep patterns. If you've ever struggled with sleep maintenance insomnia, woken at 3 AM and stared at the ceiling, or wondered whether your body is broken, this video will change how you think about sleep, history, and what it means to be human. ━━━━━━━━━━━━━ 🎶 Music used in the video: 'Decline' by Kevin MacLeod (www.incompetech.com) 'Angevin - Thatched Villagers' by Kevin MacLeod 'Thunderbird' by Kevin MacLeod 'Background Music' - Game of Thrones' by CO.AG 'A Dragon's Lullaby' by Scott Buckley (www.scottbuckley.com.au) Licensed under Creative Commons: By Attribution 4.0 License http://creativecommons.org/licenses/b... ━━━━━━━━━━━━━ 🎓 Recommended Reading: ▶'At Day's Close: Night in Times Past' by Roger Ekirch ▶'Internal Time: Chronotypes, Social Jet Lag, and Why You're So Tired' by Till Roenneberg ▶'The Slumbering Masses: Sleep, Medicine, and Modern American Life' by Matthew Wolf-Meyer ▶'Dreamland: Adventures in the Strange Science of Sleep' by David K.
