We spend a third of our lives asleep. Every organism on Earth—from rats to dolphins to fruit flies to microorganisms—relies on sleep for its survival, yet science is still wrestling with a fundamental question: Why does sleep exist? During Shakespeare and Cervantes’ time, sleep was likened to death, with body and mind falling into a deep stillness before resurrecting each new day. In reality, sleep is a flurry of action. Trillions of neurons light up. The endocrine system kicks into overdrive. The bloodstream is flooded with a potent cocktail of critically vital hormones. Such vibrant activity begs the question: Where do we go when we go to sleep? Based on new sleep research, there are tantalizing signposts. We delved into the one-eyed, half-brained sleep of some animals; eavesdropped on dreams to understand their cognitive significance; and investigated extreme and bizarre sleeping behaviors like “sleep sex” and “sleep violence.”
The World Science Festival gathers great minds in science and the arts to produce live and digital content that allows a broad general audience to engage with scientific discoveries. Our mission is to cultivate a general public informed by science, inspired by its wonder, convinced of its value, and prepared to engage with its implications for the future.
