How to use this result

This quiz is not a personality label. It is a quick way to see whether your room routine supports an early, balanced or late pattern. The useful output is a light plan, not a badge.

A late-leaning result usually needs stronger morning anchoring and less close bright light at night. An early-leaning result may need a steadier evening routine so wake time does not drift too early.

Repeat the quiz after a week of consistent morning and evening cues.

Best use

Run the tool, choose one change, repeat it for two or three nights, then compare the room notes. A repeated pattern is more useful than one perfect-looking number.
