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.

Now that Prime Day is over, and with Black Friday and Cyber Monday still a few weeks away, online deals may seem harder to come by. And while it can be a hassle to scour the internet for promo codes, buy-one-get-one deals, and flash sales, Amazon actually has an extensive coupon page you might not know about that features deals to look through every day.

As pointed out by People, the coupon page breaks deals down by categories, like electronics, home & kitchen, and groceries (the coupons even work with SNAP benefits). Since most of the deals revolve around the essentials, it's easy to stock up on items like Cottonelle toilet paper, Tide Pods, Cascade dishwasher detergent, and a 50 pack of surgical masks whenever you're running low.

But the low prices don't just stop at necessities. If you’re looking for the best deal on headphones, all you have to do is go to the electronics coupon page and it will bring up a deal on these COWIN E7 PRO noise-canceling headphones, which are now $80, thanks to a $10 coupon you could have missed.

Alternatively, if you are looking for deals on specific brands, you can search for their coupons from the page. So if you've had your eye on the Homall S-Racer gaming chair, you’ll find there's currently a coupon that saves you 5 percent, thanks to a simple search.

To discover all the deals you have been missing out on, head over to the Amazon Coupons page.

The Northern Lights Storms Are Getting Names—and You Can Offer Up Your Suggestions

While all northern lights are spectacular, they’re not all spectacular in the same way. Aurora borealis, or “northern dawn,” occurs when electrons in the magnetic field surrounding Earth transfer energy to oxygen and nitrogen molecules in the atmosphere. The molecules then emit the excess energy as light particles, which create scintillating displays whose colors and shapes depend on many known and unknown factors [PDF]—type of molecule, amount of energy transferred, location in the magnetosphere, etc.

Though the “storms” are extremely distinct from each other, they haven’t been named in the past the way hurricanes and other storms are christened. That’s now changing, courtesy of a tourism organization called Visit Arctic Europe. As Travel + Leisure reports, the organization will now christen the strongest storms with Nordic names to make it easier to keep track of them.

“There are so many northern lights visible in Arctic Europe from autumn to early spring that we started giving them names the same way other storms are named. This way, they get their own identities and it’s easier to communicate about them,” Visit Arctic Europe’s program director Rauno Posio explained in a statement.

Scientists will be able to reference the names in their studies, much like they do with hurricanes. And if you’re a tourist hoping to check out other people’s footage of the specific sky show you just witnessed, searching by name on social media will likely turn up better results than a broad “#auroraborealis.”

Visit Arctic Europe has already given names to recent northern lights storms, including Freya, after the Norse goddess of love, beauty, and fertility, and Sampo, after “the miracle machine and magic mill in the Finnish national epic poem, ‘Kalevala.’” A few other monikers pay tribute to some of the organization’s resident “aurora hunters.”

But you don’t have to be a goddess or an aurora hunter in order to get in on the action. Anybody can submit a name (along with an optional explanation for your suggestion) through the “Naming Auroras” page here. It’s probably safe to assume that submissions related to Nordic history or culture have a better chance of being chosen, but there’s technically nothing to stop you from asking Visit Arctic Europe to name a northern lights show after your dog.
