Lighting can keep moods lifted?

This little blip in the paper talks about how quarantine has made everyday life monotonous and, perhaps, the easiest remedy for those somber days. Lighting. Apparently, adjusting the way that your living space is lighted during the day and night has a substantial effect on how you work from home and transition into relaxation time. An adjustment to brighter bulbs during work hours gives the effect of sunlight to keep you energized during the day. Then at evening and night, switching to duller and warmer bulbs asserts that transition from work to relaxation. Pretty fascinating stuff!
