Blue Light and Melatonin

Sunlight's interaction with the ocean reveals that blue light is the only color that penetrates deeply, influencing life forms that evolved to detect it. This blue light activates specialized receptors in our brains, sending signals to the suprachiasmatic nucleus, which regulates melatonin production. Contrary to popular belief, melatonin isn't simply a sleep hormone; instead, it signals the body that it's time for restoration and repair during the night.
