Every human on Earth has the same 24 hours to spend in a day—but the way we divide those hours for work and sleep and school and play varies a lot.
Scientists recently compiled the available data about how people around the world allocate their time and used them to define the average “global human day.”
More than a third of our hours are spent in bed, they found, with the rest split among three categories the researchers devised based on whether the time directly affected humans, the physical world, or where and what people are doing.
Activities such as agriculture took up much more time in poorer countries than in wealthier ones, whereas others such as human transportation were fairly constant everywhere.
