    So what exactly is my chronotype?

    Ever wondered why you’re bright-eyed at dawn while your friend can barely open their eyes before noon? This variation is due to your unique biological clocks, which tick at different rates. You’ve likely observed this in various aspects of life. Some people are made for the morning, while others seem to find their stride later in the day.

    Historically, these patterns were grouped into three bird types. There were the Larks – the early risers thriving in the morning. Then, the Hummingbirds, with no strong preference for mornings or evenings. And finally, the Owls – most active and wakeful at night.

    These groups stem from something called the Morningness-Eveningness Questionnaire, or MEQ, which psychologists use to understand people’s sleep and activity preferences. But after over 15 years of working with patients and studying sleep behavior, Breus found that the traditional MEQ didn’t fully capture the diversity of his patients’ sleep behaviors. It lacked insights into the depth of sleep – or “sleep drive” – and overlooked how personality traits can also influence sleep habits.

    Driven by his observations, Breus decided to redefine these groups and create a more comprehensive assessment. He introduced four mammal-inspired groups that reflect a broader range of human behaviors.

    Dolphins, about 10 percent of the population, are light sleepers who wake easily. Lions, comprising about 15–20 percent, are morning-oriented individuals with a medium sleep drive. Bears, who make up about 50 percent, sync their routines with the sun and are typically good sleepers. And finally, Wolves, also 15–20 percent, are night-oriented and find their peak energy in the evenings.

    This new classification does a better job of addressing the limitations of the MEQ by considering sleep drive and personality. It, perhaps, also resonates more with human behaviors since we are, after all, mammals and not birds.

    Each chronotype has a unique daily rhythm that suits their natural inclinations. For instance, if you’re a Lion, you start your day early, making the most of the morning. If you’re a Wolf, you find your peak energy later in the day.

    Understanding your unique chronotype can help you tailor your daily activities to match your natural inclinations for better health and productivity. You may already have a good idea as to which chronotype you are, but you can also get a more accurate picture by taking Breus’s Bio-Time Quiz, which unfortunately we don’t have space to include in this Blink. But once you’re sure you have the right idea of your own type, let’s look at some of the traits.
