With all that extra time, they tend to be multitaskers,” Fu says. “These short sleepers not only need less sleep, but while they’re awake-for 18 to 20 hours- they are more active than typical sleepers. These people are truly lucky, her research finds, because they seem to share some awesome characteristics: They tend to live longer and healthier lives, both physically and mentally. While it’s a rare individual who is genetically wired to sleep fewer hours in a day, all of the people she and her team have identified as short sleepers have several things in common. And that’s a hallmark of short sleepers, who need about half as much sleep as the vast majority, but perform as well as regular sleepers, Fu explains to Popular Mechanics. The more efficient your sleep is, the less you need. ![]() Sleeping many hours does not necessarily correlate with getting quality sleep, however. Sleep governs your cognitive and neurological functions, like memory, thinking, learning, moving, and feeling energetic. At this point, her team had identified five mutations in three genes that control how much shut-eye people need, but Fu suspects there are more genes involved. She and her team found in 2009 that the genes of so-called “short sleepers” have certain mutations that are responsible for super-efficient sleep. Researcher Ying-Hui Fu of the Weill Institute for Neurosciences at the University of California, San Francisco studies sleep behaviors and circadian rhythms-the body’s natural clock for sleeping. During the studies, Johnson answered extensive questionnaires about his sleep habits and health, and researchers monitored his daily sleep and activity levels for eight days. A few years later, he participated in a follow-up sleep study because his blood showed specific gene mutations that most people don’t have. He decided to join a sleep study to identify people who do remarkably well on very little sleep. It wasn’t until 2005 that Johnson started to find some answers. Amidst this very busy lifestyle, he still wondered why he felt great after just six hours of sleep, and why he never needed an alarm clock to awake refreshed every morning. ![]() “Less than, and I have the same problems everyone else does if they’re sleep-deprived,” he explains.Īs time went on, Johnson did well at college, went on to hold top leadership positions at Lands’ End and REI, became very active with his church, and had eight children with his wife. For them, six hours of sleep is the equivalent of eight or nine hours for most people. Since childhood, the same was true of four of his seven siblings and his father. For as long as he can remember, he has slept only between four and six hours a night. And everything you read says you’d have to have seven, eight, nine hours of sleep, or you’re staring serious health conditions in the face, and you can’t ever be as productive,” Johnson, 65, tells Popular Mechanics. “I just physically cannot sleep like other people. Despite being an energetic and focused child, and later a high-achieving adult, Johnson carried this worry in the back of his mind. Their super-efficient sleep helps maintain better health and greater resilience to stress.Īt first, Brad Johnson thought his inability to sleep as much as other people meant there was something wrong with him.Researchers have discovered particular mutations in three genes that control short sleepers’ resting needs.Short sleepers are people who do well with about half of the shut-eye that the rest of us require to function.
