How to Find Your Chronotype—And How Knowing It Can Help You

You probably know if you’re an early bird or a night owl. But did you know that there are two other in-between types? Discovering your unique bio-time—a.k.a. your chronotype—can help dictate the best time for you to make an important decision or take the next step in your career.

Michael Breus, a clinical psychologist and fellow of the Academy of Sleep Medicine, examined more than 200 studies to write his book, The Power of When. Take the 45-second free online quiz to learn your unique chronotype (Breus divides everyone into four categories: Bears, Wolves, Dolphins, and Lions), and then read on to see when you should be doing what. 

THE BEST TIME TO MAKE A DECISION

In order to make a decision, your brain needs to function on an emotional level and on a logical level, Breus says. In emotional terms, if you feel afraid and insecure, it can cause you to act cautiously. Sleep deprivation and your tendency towards procrastination also affect your decision-making skills, but the biggest factor is your personal circadian rhythm, and this depends on your chronotype.

According to Breus, Lions will make the best decisions first thing in the morning, from 6:00 to 11:00 a.m. “You’ll be alert, ready to go, understanding what’s happening,” Breus says. Bears, who wake a little later, should plan major moves for before lunch (between 8:00 and 11:00 a.m.), while Dolphins do best from 10:00 a.m. to 2:00 p.m.

Wolves, who are night people, have two windows for optimal decisiveness: 12:00 to 2:00 p.m. and again from 5:00 p.m. to 1:00 a.m. They need the break in the middle of the day because their sugar levels drop, and they shouldn’t make a decision on an empty stomach. Also, right before bed in the evening is prime decision-making time for everyone, because creative ideas often come when you’re about to fall asleep and your mind is a little distracted, Breus says. 

THE BEST TIME TO SCHEDULE A JOB INTERVIEW

In order to game your job interview, it’s best to know the circadian rhythm of your interviewer as well. “Most leaders are Lions anyway,” Breus says, explaining that they’re at their best first thing in the morning. But are you? You don’t want to be there at 8:00 a.m. if you aren’t going to be able to function.

On the flip side, you also don’t want to be the last interview of the day. “If [your interviewer] thought that everyone was good, they’re going to downgrade you because they’re going to think that they need to think that someone wasn’t good . . . and you’re up, so that must be you,” Breus says. Finding the right balance "is not an exact science," Breus says, "but it works well.”

THE BEST TIME TO ASK FOR A RAISE

First, it’s important to determine the circadian rhythm of your boss. Take notice of the time they arrive in the office relative to your company's required start-time. Say work starts at 9:00 a.m.: If they stroll through the doors at 7:30, they’re probably a Lion. Arriving at 8:30 makes them a Bear, and 10:00 a.m. (in this scenario) probably means they're a Wolf. If you’re getting emails from them at all times of the night, they’re probably a Dolphin.

Don’t time the question too close to lunch, because no one wants to have a big conversation when their blood sugar is low and they’re heading out to grab a sandwich. Right after lunch is best, and your boss's preferred lunchtime most likely depends once again on their chronotype. For Lions, it's likely around 12:30 p.m.; Bears at 1:00 , Wolves between 2:00 and 3:00, and Dolphins at around 3:30.

Next, choose the day. “People become more and more positive as the week goes forward,” he says. Friday is the most positive day, and most people are happier later in the day. But you don’t want to schedule anything for after 4:00 p.m., because anything past 4:00 on a Friday is margarita time, Breus says.

Map Shows How Everyone Blamed Syphilis on Everyone Else

The origins of syphilis may be one of the greatest (and grossest) health mysteries of our time. Some historians claim that Christopher Columbus and his sailors contracted the sexually transmitted disease in the New World and brought it back to Europe. Other experts believe that the disease, which is caused by the bacterium Treponema pallidum, existed in various forms around the globe but was simply misclassified as other conditions. (European writers, including Italian historian Niccolo Squillaci, first described syphilis in the late 15th century.) And in 2015, researchers announced that they had identified signs of congenital syphilis in 14th-century skeletons from St. Polten, Austria, adding new evidence to an ages-old debate.

One thing's for sure: As the map below illustrates, nobody wanted to take credit for originating the virulent condition. Created by Redditor masiakasaurus (and spotted by The A.V. Club), the map illustrates the various nicknames Europeans gave the disease before the name syphilis caught on. (Italian physician and poet Hieronymus Fracastorius coined the word in 1530 with his poem "Syphilis Sive Morbus Gallicus" ("Syphilis or the French Disease"). Not surprisingly, nearly every single moniker used for the disease places blame on another group for giving birth to what by then had become a continental scourge.

“Most physicians felt that this was a new disease, that it hadn’t been seen before in Europe, and that view tended to prevail for quite some time,” medical historian John Parascandola told The Atlantic in 2016. “There were certain tempting reasons for people to accept that—blame it on the others, blame it on the outsiders. Before that, the French were blaming it on the Italians, the Italians were blaming it on the French, et cetera.”

Masiakasaurus sourced the syphilis nicknames from nine scholarly books/journals, including The Early History of Syphilis: A Reappraisal,The rise and fall of sexually transmitted diseases in Sweden, and A Medical History of Persia and the Eastern Caliphate: From the Earliest Times Until the Year A.D. 1932. You can view the full list on Reddit—after giving silent thanks to Alexander Fleming for discovering penicillin, found to be an effective cure for syphilis in 1943.
