Описание: People used to sleep in two shifts, and it was so common that it had names: first sleep and second sleep. In this episode of Watercooler Facts, we explore how two-part sleep worked, what people did during the midnight “watch,” and how artificial light slowly reshaped nighttime into the single block of sleep we expect today. If you’ve ever woken up at 2 or 3 a.m. and wondered why, this forgotten history might change how you see it.
