Chronotypes

YOUR CHRONOTYPE

Bear

The bear is the most common human chronotype, found in roughly 55% of the population. People with the bear chronotype — like bears in the wild — essentially follow the sun, waking up when the sun rises in early morning and retiring as darkness falls in the early evening. Their peak productivity hours are 10 a.m. to 2 p.m.
YOUR CHRONOTYPE

Lion

People with the lion chronotype tend to wake up early, often around 5 a.m., and feel most energetic and productive before noon. Lions tend to feel most accomplished when they tackle their daily to-do list as soon as possible. As energy levels begin to fall in the early afternoon, lions typically wind down in the early evening and fall asleep no later than 10 p.m. Roughly 15% of people have the lion chronotype.
YOUR CHRONOTYPE

Wolf

If you know someone who isn’t a “morning person,” chances are they’re a wolf — about 15% of the population has this chronotype. Wolves usually wake up later in the day, and feel most productive between 10 a.m. and 4 p.m. They’ll also get bursts of energy in the evening. Midnight or later is a common bedtime for wolves.
YOUR CHRONOTYPE

Dolphin

About 10% of people have the dolphin chronotype, which is the hardest to form a schedule around without sacrificing sleep quality. This chronotype gets its name because dolphins in the wild remain alert while sleeping to evade predators. People with this chronotype tend to be sensitive to light and noise while they sleep, and prone to fragmented sleep patterns. Many are considered insomniacs. However, dolphins have a strong productivity window between 10 a.m. and 2 p.m.
