Sleeping Beauty Syndrome: The Disorder Where You Sleep All Day

Fairy tales made their way into the modern literary sphere when French author Charles Perrault published Histoires ou contes du temps passé in 1697 (literally, “Stories or tales of times past”). Histoires was a collection of stories that quickly permeated our culture, including the now-famous Cinderella, Puss in Boots, Little Red Riding Hood, and Sleeping Beauty. Whatever basis Perrault’s stories have in reality are quite tenuous at best — one doesn’t see pumpkins-as-chariots, swashbuckling cats, or wolves wearing grandma’s bed clothes in the real world.

The sleeping-for-a-century part of the Sleeping Beauty tale is also total fiction. But sleeping for days on end is not. It is perfectly possible and, if it happens, most likely due to a neurological disorder called Kleine-Levin Syndrome (KLS), or, colloquially, Sleeping Beauty Syndrome.

Those affected by KLS sleep the whole day and night away, waking only to eat and use the bathroom, and typically only briefly at that (although some KLS sufferers report elongated eating binges). While awake, the person appears zombie-like, having little energy and showing even less emotion. Many are unable to even communicate while awake. In extreme cases, such as the case of Louise Ball in the UK, episodes can last as long as ten days and waking up is rare. Caretakers (in Ball’s case, her parents) are instructed to try to wake the person to get him or her to use the bathroom and try to eat.

KLS is most prevalent in teenagers, with the first onset occurring, on average, at about age 15 — and with no discernible cause. Episodes can occur as frequently as every few weeks to only once in five years, but on average, the sleeping spells occur every six months. By a KLS sufferer’s mid-to-late 20s, the syndrome often disappears, again with no discernible cause. Similarly, KLS is difficult to diagnose, as there are no markers unique to it other than the symptom set, and physicians need to eliminate all other possible causes before declaring KLS the cause of the lethargy. Because of this, the syndrome often takes years to correctly diagnose. The good news is that it's extremely rare: It affects only about six people in ten thousand.

Netflix's Most-Binged Shows of 2017, Ranked

Netflix might know your TV habits better than you do. Recently, the entertainment company's normally tight-lipped number-crunchers looked at user data collected between November 1, 2016 and November 1, 2017 to see which series people were powering through and which ones they were digesting more slowly. By analyzing members’ average daily viewing habits, they were able to determine which programs were more likely to be “binged” (or watched for more than two hours per day) and which were more often “savored” (or watched for less than two hours per day) by viewers.

They found that the highest number of Netflix bingers glutted themselves on the true crime parody American Vandal, followed by the Brazilian sci-fi series 3%, and the drama-mystery 13 Reasons Why. Other shows that had viewers glued to the couch in 2017 included Anne with an E, the Canadian series based on L. M. Montgomery's 1908 novel Anne of Green Gables, and the live-action Archie comics-inspired Riverdale.

In contrast, TV shows that viewers enjoyed more slowly included the Emmy-winning drama The Crown, followed by Big Mouth, Neo Yokio, A Series of Unfortunate Events, GLOW, Friends from College, and Ozark.

There's a dark side to this data, though: While the company isn't around to judge your sweatpants and the chip crumbs stuck to your couch, Netflix is privy to even your most embarrassing viewing habits. The company recently used this info to publicly call out a small group of users who turned their binges into full-fledged benders:

Oh, and if you're the one person in Antarctica binging Shameless, the streaming giant just outed you, too.

Netflix broke down their full findings in the infographic below and, Big Brother vibes aside, the data is pretty fascinating. It even includes survey data on which shows prompted viewers to “Netflix cheat” on their significant others and which shows were enjoyed by the entire family.
