Question 1 of 10

Your ideal sleep schedule

Your traits

The four chronotypes

Based on Dr. Michael Breus's research — your chronotype is largely genetic and changes with age

🦁

Lion — Early Riser

~15%

Lions wake naturally before 6 AM, peak in the morning, and fade by evening. They're the most productive in the first half of the day. Lions make excellent executives and leaders, but struggle at late-night social events. Best bedtime: 9–10 PM. Best wake time: 5–6 AM.

🐻

Bear — Solar Follower

~55%

Bears follow the solar cycle — they wake with the sun, hit peak performance mid-morning, and wind down in the evening. The "average" human sleep schedule was designed around Bears. Best bedtime: 10–11 PM. Best wake time: 7–8 AM.

🐺

Wolf — Night Owl

~25%

Wolves' brains don't hit peak performance until evening. They're creative, introverted, and struggle with early mornings — not by choice. Standard 9–5 schedules work against their biology. Best bedtime: 12–1 AM. Best wake time: 8–9 AM.

🐬

Dolphin — Light Sleeper

~5%

Dolphins are light, fitful sleepers — even in animals, dolphins sleep with one hemisphere at a time. They're often highly intelligent, anxious perfectionists who wake easily. Best bedtime: 11:30 PM. Best wake time: 6:30 AM. Prioritize sleep environment over timing.

Common questions

Partially. Your chronotype has a strong genetic component — it can't be fully changed. But you can shift your sleep timing by 1–2 hours through consistent sleep/wake times, strategic light exposure, and caffeine timing. Teenagers naturally shift toward Wolf, and tend to drift back toward Bear or Lion in their 20s.

The health risks aren't from being a Wolf — they're from living in a world designed for Bears and Lions. When Wolves are forced to wake early every day, they accumulate chronic sleep debt. Studies on Wolves who can work on their own schedule show no health differences from Bears. It's the mismatch, not the chronotype, that causes problems.

Children tend toward early chronotypes (Lion). Teens shift dramatically toward Wolf — peaking around age 19–21. Through your 20s and 30s, there's a gradual drift back toward Bear. After 60, many people shift toward Lion again. Hormones, particularly during puberty and menopause, drive these shifts.

Think about your "free" days — weekends or holidays with no alarms or obligations. When do you naturally fall asleep and wake up? That's your true chronotype, unconstrained by social schedule. If you sleep until noon on free days, you're likely a Wolf even if you're forced to wake at 6 AM on workdays.
