Sleep mask or blackout curtains? Start with where the light comes from
Own Rhythm — optional worksheet, not a diagnostic test. Blank means unknown. Keep completed notes private.

- Window light: is it passing through fabric or around the edges?
- Indoor light: is a lamp or a device display responsible?
- Shared space: does someone need a light on while you rest?
- Practical limits: are you allowed to install fittings, and can you reach them safely?

睡眠眼罩还是遮光窗帘？先看光从哪里来
Own Rhythm — 可选记录工具，不是诊断量表。空白表示未知，请私密保存。

- 窗外光：是穿过布料，还是从边缘进入？
- 房内光：是不是台灯或设备显示屏？
- 共用空间：你休息时，别人是否需要开灯？
- 现实限制：允许安装配件吗？能否安全够到？
