Sleeping in two shifts

"Intriguingly, right about the time accounts of first sleep and second sleep began to wane, references to insomnia began appearing. Foster isn’t the only one who wonders if this isn’t a biological response to un-segmented sleep. Sleep psychologist Gregg Jacobs tells BBC, ”For most of evolution we slept a certain way. Waking up during the night is part of normal human physiology.” He also notes that the watch was often a time for reflection and meditation that we may miss. "Today we spend less time doing those things," he says. "It's not a coincidence that, in modern life, the number of people who report anxiety, stress, depression, alcoholism and drug abuse has gone up." It may also not a coincidence, though, that we don’t die at 40 anymore."
