Who Are The ‘Sleepless Elite’ (And How Do You Become One)?

Jim Cramer, host of CNBC’s Mad Money and co-founder of TheStreet.com, claims to only need four hours of sleep each night to feel well-rested and alert. Cramer said he sleeps between 11:30 p.m. and 3:45 a.m. most weeknights, and rarely needs an alarm to rise. His father, he says, was the same way, only taking a couple of naps but never sleeping a full eight hours.

Cramer’s not the only one: Leaders such as Theranos CEO Elizabeth Holmes, Yahoo CEO Marissa Mayer, and even ex-US President Barack Obama rarely — if ever — get what’s considered a full night of sleep.

Though not officially diagnosed, these sleep habits are consistent with those of a condition known as “short sleeping.” Short sleepers, a group the Wall Street Journal once named the “sleepless elite,” need only a short amount of sleep every night instead of the average 7-8 hours, and scientists estimate they make up only about 1% of the population.

The Short Sleep Clinic

Even though it has no apparent negative health effects, short sleeping is considered a sleep disorder.

And although many people think they can get by with just four hours of sleep, for the most part they aren’t true short sleepers — they’re just chronically sleep deprived.

Ying-Hui Fu, a biologist and human genetics professor at the University of California, San Francisco started studying short sleepers in 1996, when a woman came into the lab asking them to investigate why her whole family woke up at extremely early hours every day. Fu started investigating the traits relating to that family and others who came into the clinic. Soon, she learned that there were three types of people: early risers, night owls, and people who are somewhere in between. Perhaps most importantly, she also learned that there were specific traits linked with all three types.

That launched close to 20 years of studying these sleep behaviours to learn more about how people sleep and how genetics may play a role in that behaviour.

“We know almost nothing about how sleep is regulated,” Fu told Business Insider.

That’s at least partially because the research money isn’t there. With other disease areas to focus on, it’s hard to see the value in exploring the complicated topic of sleep, though it could be a great area for a potential gene therapy, which is an ever-growing research area. For now, most sleep research money goes into funding treatments for sleeping disorders that deprive them of sleep, and those treatments are focused on helping people sleep more, not less.

But Fu thinks that belies how critical this research is. “Other than water and air, nothing is more important” than sleep, she said. Which is why she’s dedicated her lab to learning everything she can.

Because here’s the thing about short sleepers: They’re not people with insomnia, nor are they people with insane caffeine addictions that keep them from getting fully rested. Instead, short sleepers wake up after very little sleep well rested and ready for the day. They will always wake up early — even on vacation, and they tend to have similar behavioural characteristics as well, like being physically active and optimistic.

And these similarities aren’t limited to how they act: they’re genetic as well, meaning they can get passed on through generations.

Abby Ross: Mother, doctor of psychology, marathoner, ‘awaker’

Abby Ross has never needed what’s considered a full night of sleep.

And for 64 years, Ross didn’t have an answer to why she woke up feeling chipper and ready for the day, even after just four hours of sleep. That’s when she went to Fu’s lab and learned she was a short sleeper.

At 64, she began reading about short sleepers and quickly realised she fit the bill. She decided to contribute to research at Fu’s lab, giving blood and answering questions from psychologists and doctors from all over the world. Ross still doesn’t know if she has the genes that have since been linked with being a short sleeper. When she joined Fu’s study, she agreed that any information the researchers gathered about her genes linked with short sleeping wouldn’t be shared with her.

The lab’s rationale for this, as they described it to Ross, is that if someone who came in with short sleeping symptoms didn’t have any of the already-identified short-sleeper genes, that wouldn’t mean they weren’t technically a short sleeper. Rather, they may have another gene linked with the disorder that Fu’s lab has yet to identify. Ross won’t ever get her results, though she says the information she’s gotten so far is enough.

“I learned that what I have is truly a gift,” she told Business Insider.

As long as she can remember, Ross said, she’s been a short sleeper, even she didn’t have a label for it until recently. When she was young, she’d always be up early to get bagels and coffee with her parents. This early development of short sleeping habits is consistent with other short sleepers, who typically develop the habit sometime in childhood or as a young adult.

At Northwestern University, Ross got her undergraduate degree in three years by taking more classes than the average course load, which just happened naturally for her. To her, an “all-nighter” wasn’t a dreaded way to cram in some last-minute studying before a midterm; it was just a regular night. Plus, Ross says, she’s always had an easy time falling asleep, so if her body needed an hour or two, she’d take a nap, then pick up right where she left off. After Northwestern, Ross went on to graduate school to study psychology. At the same time, she started a family. And when her daughter was in kindergarten, Ross started her doctorate.

At 35, Ross had two more kids, all while writing her dissertation and raising the first. “If I got up to feed the baby,” she recalled, “I could stay up studying psychology.”

Ross went on to work at two universities, while staying active in a number of organisations. She did it all, she said, by developing a respect for her body clock.

“It gave me permission to accept that if my husband goes to bed at 10:30, then I stay up,” she said. “It’s just the way it is.”

In true short sleeper form, Ross has led an incredibly active life. Ten years ago, she ran 37 marathons in as many months. In one of those months, she did three marathons. Even now, she tends to log about five miles of walking and other activity on her Fitbit each day.

Ross puts her extra hours to good use, using them to do everything from catalogue family photos to catch up with loved ones.

And it runs in the family: Ross’ 92-year-old father is also a short sleeper. For years, the two have emailed each other around 5 a.m. every morning to start their days.

For the most part, Ross has embraced her short sleeping gift, in all but name.

“I think the name is really weird” she said, since it sounds like people are referring to her height.

Instead of a short sleeper, Ross would like to be called an “awaker.”

Recent developments

Being a short sleeper is, for the most part, genetic.

So far, Fu has pinpointed several genes connected to the disorder. One such gene is DEC2, a gene known to effect our circadian rhythm, the biological process influenced by light and temperature that helps determine when we sleep and when we wake up. The other genes have yet to be published.

One of the main reasons Fu’s lab hasn’t been able to publish their latest findings is because it takes quite a long time — 10 years, she said — to publish the type of sleep-related paper she is looking to publish. For these studies, researchers have to find and recruit short sleepers, which as only 1% of the population aren’t easy to come by.

Plus, running the tests can be a lengthy process, as can funding all of the specialists who come in to run the tests and conduct interviews. Finally, processing the data and getting the paper peer reviewed and accepted into a journal can be time consuming as well.

That’s because not much money is going into sleep studies, which Fu said is the wrong approach, since understanding sleep habits could help people avoid diseases that are worsened by sleep deprivation.

“Instead of putting the fire out, let’s try to avoid fire,” she said.

No official long-term health effects have been linked to being a short sleeper, though Fu said that is one concern her lab is looking into. For the most part, the people coming into Fu’s lab are generally anywhere from 40 to 70 years old and in good health. Most stay active into their later years, and Fu said she’s even had one volunteer in her lab who was 90 years old, so she hypothesizes that longevity could also be linked with being a short sleeper.

Ideally, Fu hopes to one day crack the code on how to become a short sleeper without being born with it. Then, maybe there will be more research focus to develop a gene therapy that can adapt people into short sleepers.

“I feel someday in the long-distance future, we can all sleep efficiently, and be healthy and smart,” she said. “It’s appealing to me.”
