A time-altering experience

In 1938, 43-year-old researcher Nathaniel Kleitman and his student, 25-year-old Bruce Richardson, descended into the belly of Kentucky’s Mammoth Cave in a serious quest for more hours in the week. They theorized that hidden away from the Sun and its inexorable 24-hour day, they might be able to cheat their need for sleep—just a little—and come out with more waking hours in the day.

For almost 5 weeks, they lived a reinvented 28-hour day in which they were awake for 19 hours and then slept for nine. The result? Richardson adapted to the 28-hour-day without symptoms of sleep deprivation, but Kleitman did not.

The data they gathered made an enormous contribution to our understanding of human circadian rhythms. Kleitman went on to become the father of modern sleep research, codiscover REM (rapid eye movement) sleep, and live to be 104 years old.
