@memyselfandi You may get more answers if you make a separate thread for your question, but there is a lot of evidence that the lights we’ve become so accustomed to in our homes at night could interfere with sleep, especially if they are white/blue/green light.
Many people choose to use red lights at night to avoid having to use white, blue or green lights to see. They do report having an easier time sleeping at night after making that change.
