Five questions, two minutes

What's your sleep chronotype?

Most of when you want to sleep was decided for you. A roughly 24-hour clock in your body cues when you feel sharp, when you feel hungry and when you finally feel tired, and your chronotype is where that clock sits against everyone else's. Early types peak before lunch. Late types come alive after dark. Most people sit somewhere in the middle, and the setting drifts with age: children run early, teenagers run late.

The five questions below are adapted from the reduced Morningness–Eveningness Questionnaire, the short form of the instrument sleep researchers have used since 1976. Answer for the life you would choose, not the one your alarm imposes.

1. If you were entirely free to plan your day, when would you get up?
2. In the first half hour after waking, how do you feel?
3. In the evening, when do you start to feel tired and in need of sleep?
4. At what time of day do you feel at your best?
5. People talk about morning types and evening types. Which are you?
