Modafinil is just the first of a wave of new lifestyle drugs that promise to do for sleep what the contraceptive pill did for sex – unshackle it from nature. Since time immemorial, humans have structured their lives around sleep. In the near future, we will, for the first time, be able to significantly structure the way we sleep to suit our lifestyles.
“The more we understand about the body’s 24-hour clock the more we will be able to override it,” says Professor Russell Foster, a circadian biologist at Imperial College London. “In 10 to 20 years we’ll be able to pharmacologically turn sleep off. Mimicking sleep will take longer, but I can see it happening.” Professor Foster envisages a world in which it’s possible, or even routine, for people to be active for 22 hours a day and sleep for two.
I can see this having a lot of appeal. Sleeping only four hours per night could add an entire half workday of productive time to every day of your life. What would we do with the time if we had it?
I also like the idea of being able to turn sleep on when needed. If it were an option, I would always sleep through every flight I have to take.
