Circadian Chronotype Quiz
Discover whether your internal clock aligns with Lion (early), Bear (solar), Wolf (late), or Dolphin (light sleeper) rhythms.
What is a chronotype (Lion, Bear, Wolf, Dolphin)?
Your chronotype reflects your biological preference for waking early (Lion), following daylight (Bear), thriving late (Wolf), or light fragmented sleep (Dolphin). Matching your schedule to it boosts focus and rest.
1. On a free weekend with zero alarms, when do you naturally wake up?
2. When does your brain feel sharpest for deep analytical work?
3. How quickly do you feel alert after waking up?
4. When does natural sleepiness usually hit in the evening?
5. If you had to take an important exam or athletic test, when would you schedule it?
Gradual Sunrise Alarm Clocks
Pair cycle-aligned wake windows with a 30-minute progressive dawn simulator to suppress morning melatonin smoothly.

What is a circadian chronotype vs sleep disorder?
A chronotype reflects your genetic preference for morning (Lion), solar middle (Bear), evening (Wolf), or light fragmented alertness (Dolphin)—it is normal biology unless forced schedules cause chronic insomnia.
Can your chronotype shift over your lifetime?
Yes. Teenagers naturally delay toward evening rhythms due to puberty melatonin shifts, whereas adults past age 55 gradually advance earlier by roughly 15–20 minutes per decade.
When is peak cognitive focus for each chronotype?
Lions peak early (8 AM–12 PM), Bears peak mid-morning (10 AM–2 PM), Wolves hit deep focus late afternoon and night (5 PM–11 PM), and Dolphins thrive in structured late-morning blocks.
