Lark, owl, bear or fox: what is your chronotype?
What a chronotype is, why people differ, and how to plan your day around yours.
By Best Sleep Trackers · Updated October 18, 2026
Some people wake early and fade in the evening. Others come alive late. The chronotype quiz asks nine original questions and gives a playful animal: lark, bear, fox or owl.
The four animals
- Lark: early riser, early energy, early to flag.
- Bear: follows the sun with steady daytime energy.
- Fox: warms up slowly and gets a second wind in the evening.
- Owl: lively late, prefers a late schedule.
The quiz is for fun and planning. It is not a clinical test, and most people sit between two types.
Why it changes
Body clocks shift with age. In the teen years they tend to move later, which is one reason early school starts are hard (AASM position statement; see why teens fall asleep late).
Using your result
- Plan demanding work for your best hours.
- Anchor your wake-up time and get daylight soon after waking to keep your clock steady.
- Owls: shift earlier gradually, not overnight. Try the bedtime calculator.
- Track the pattern for a week in the sleep diary.
If you are sleepy all day despite enough sleep, speak to a doctor.
