Why do living things sleep? “Ask researchers this question and hear awe and frustration creep into their voices, like clockwork,” Veronique Greenwood wrote in 2018.
“In some ways, it’s amazing how universal sleep is,” she continued. “Throughout thousands of years of bloodshed, death and flight, countless millions of creatures have laid themselves in a lengthy state of unconsciousness in the scramble for survival. This doesn’t seem conducive to living to fight another day…that such dangerous habits are so common and so enduring that what’s going on This suggests that whether or not is most important.
In other words, Greenwood writes: Whatever sleep gives us is also worth the lot of time and lots of money humans spend figuring out how to get the most out of it. Every night, or almost every night, they report experiencing sleep disturbances, noted Amanda Mull in 2019.
Sleep is necessary, but it is also a ritual. Where you sleep, when you sleep, and who you sleep with next can say a lot about who you are and what you want. Today’s reading list explores scientific mysteries, physical needs, and sleep as the most consistent routine of our daily lives.

Scientists don’t know yet.
