I purchased one of the Philips Wake-Up Light Alarm Clock with Sunlight Simulation in the hopes that it'll help me wake up in the morning!
I want something like this, but normal LED light bulbs that change throughout the day. As sunlight changes throughout the day and your body senses this. So would be nice to have said light bulbs all over the house. As well as computer displays that mimic it.
Iirc as the sun gets lower on the horizon, atmosphere blocks out a lot of the blue light, which your eye balls detect and use this for your sleep pattern.
