Yes. I do the same thing with my LED houselights, making them yellow and then orange in the evening. When I set them to white temporarily and then forget to change them back I've noticed it seems to increase my alertness/delay drowsiness.

It's most likely just that I've conditioned myself, but in practice I don't really care about the cause. I only care that it helps me wind down in the evening.



If you use home assistant there are some addons that allow you to sync the temperature of your LED bulbs to how high the sun is at the moment in your location... it's pretty neat. https://github.com/claytonjn/hass-circadian_lighting


Yep, I also do this. It's excellent. Whether it's conditioning, placebo, or an effect of the receptors in the eyes; I'll take it.

There's something that feels good about being in sync with the natural day/night cycle. Cool white in the morning, warmer more dim light at night. I also like the idea of having a "sunrise/sunset" wall for any room that doesn't have proper windows but I've never implemented it.


+1 / thank you to everyone who added the conditioning causative effect to thread
