An investigation, celebration, and vindication of "noctonauts," those of us who are most productive at night.

As a culture, we revere early birds. The early bird catches the worm, right? We exalt those early risers as disciplined, productive, put-together members of society. But what about those of us more inclined to burn the midnight oil? For centuries, night owls have been deemed lazy, unmotivated, and childish-unfounded characterizations that nonetheless follow late sleepers throughout their lives.

What if staying up late was seen as a superpower rather than a failing? After all, people who sleep later often have a higher IQ, are more creative, and spend more of the day mentally alert than their early-rising counterparts. And while many portray sleep schedules as a matter of sheer discipline, sleep cycles are in fact baked into our DNA, based on centuries of evolution. While they can be adjusted, there's only so much wiggle room.

In Night Owl, journalist (and lifelong noctonaut) Haley Shapley sifts through academic research, historical anecdotes, and expert interviews to create a compelling, fast-paced read on the culture of night owls, offering insight on everything from how they evolved and the ways sleep varies around the world to the benefits and drawbacks of going to bed later and why it would be good for everyone if we better accommodated the very real, very normal variation in sleep-wake patterns among humans. The result is a long-overdue celebration of a large but misunderstood population, with the power to change our relationships to sleep, to ourselves, and to one another.
