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.
