    TLDR Low color temperature light (1900 K) benefits health by promoting melatonin, protecting eyes, and aiding healing.
    The study evaluated the biological effects of four artificial lights with different color temperatures (1900 K, 3000 K, 4000 K, and 6600 K) on human and murine models, involving 152 person-times. The low color temperature light (1900 K) was found to have several benefits compared to higher color temperature lights. It promoted melatonin and glutamate secretion, protected human eyes, and accelerated wound healing and hair regeneration. These findings suggested that the 1900 K light could offer significant health benefits in daily life.
