🕰️ What is Chronotype?
Chronotype（生理時型） refers to your natural preference for sleep and activity times. It determines when you’re most alert, productive, and energetic during the day. It’s influenced by your internal circadian rhythm and largely shaped by genetics.
In simple terms, chronotype tells you: “What kind of internal clock person are you?”
⏰ 4 Common Chronotypes (Animal Types)
These are based on Dr. Michael Breus’s book The Power of When:
| Chronotype | Peak Productivity Time | Traits |
|---|---|---|
| 🐻 Bear | 9:00–17:00 (daytime) | Most people fall here; energy rises and falls with the sun. |
| 🦁 Lion | 6:00–14:00 (early morning) | Early risers; energized in the morning, fade by evening. |
| 🐺 Wolf | 13:00–21:00 (afternoon/evening) | Night owls; slow starters, peak later in the day. |
| 🐬 Dolphin | Unpredictable | Light sleepers, easily disturbed, irregular energy. |

🧭 Why Knowing Your Chronotype Helps
- Smarter scheduling: Tackle hard tasks when you’re naturally most alert.
- Avoid energy mismatches: Night owls should avoid deep work early in the morning.
- Better lifestyle choices: Sleep, eat, and exercise at times aligned with your internal rhythm.
