Melatonin Window
The melatonin window is the roughly ninety-minute span when natural melatonin rises and body temperature falls, ideal for initiating sleep. Bright light, screens, and late meals can shift or blunt this window.

Dim light and a fixed wind-down anchor help you catch the window nightly.
