Companies are enhancing office lighting to attract remote workers back. Circadian lighting aligns with our biological clocks, regulating melatonin and serotonin levels by mimicking the sun’s pattern—increasing intensity until midday, then dimming in the afternoon, with color temperature shifts from cooler to warmer to cooler.

Artificial windows and skylights, preprogrammed to replicate outdoor conditions, provide virtual sunlight and moonlight to offices obstructed by other buildings or the floor above. Some companies offer cordless rechargeable lamps to bring a home-like vibe to individual workspaces. Others allow employees to use a remote control to adjust lighting intensity, color and aspects of phototherapy, a treatment designed to boost mood and well-being. Lighting options also enable employees to optimize their appearance on video conferences by dimming overhead lights and darkening room edges
