Sleep claims a third of human life. Like water, it’s not a desire but a necessity. Sleep rules virtually every important system: brain, heart, mood, and immunity. Nature’s terms are harsh. Sleep eight hours or face mental and physical decay. Can we rewrite the terms in our favor? Can we sleep less, but still feel refreshed? I believe we can, and that now is the best time to start engineering sleep. Rare mutations suggest a great variation in sleep efficiency between people. A small proportion of the population have Familial Natural Short Sleep (FNSS), a benign mutation that allows them to sleep 1-2 hours less than the recommended 7-9 hours, without experiencing the negative effects of sleep deprivation [1]. Contrary to symptoms of chronic sleep deprivation, people with FNSS are “healthy, energetic, optimistic, with high pain threshold, and do not seem to suffer adverse effects of chronic restricted sleep” [2]. This goes against everything we know about sleep. The most plausible explana
