Is it possible to sleep less?
Today, I am bright-eyed and bushy-tailed, a chatty Kathy with my officemates, eager to spend all afternoon banging on the keyboard. (I normally prefer chewing my fingers off to writing.) I am not exactly wired, but I’m more alert, more focused, more Plotz-like. Today I am my own Superman, dosed on 100 milligrams of Provigil.
Every year, we need the same amount of sleep, and every year we get less. Since the invention of artificial illumination, sleep has been a bear market. There are many reasons we catch fewer Z’s: Round-the-clock workplaces, longer commutes, brighter lights, 24-hour Krispy Kreme stores, the Home Shopping Network—the list goes on. According to University of Pennsylvania professor of psychology David Dinges, Americans probably sleep about six and a half to seven hours per night, compared to the more than eight hours our bodies want.
