LED lighting is good for the body clock settings. Particularly the ones with plenty of blue. 20 years or more ago when I lived with a lass who experienced cabin fever, I bought her a "Outside In" alarm clock. It switched on a light in progressively brighter intensity until at full brightness the alarm went off. She thought it was wonderful for a week, and then got antagonistic about it. And me! The same company sold sunshade type peaks with LED down light & batteries that you could read by which were good for noon body clock re-setting, on a plane (eg). And light panels, etc. I eventually solved the problem by leaving, which pleased her too! I reckoned she had the hibernation gene --- on boost. Anything I did was a stress to that. The best laid plans of mice and men and all that..........
