The science of what light does to the living, from sunburn to seasonal depression.
means The study of how light interacts with living organisms, covering everything from photosynthesis to how sunlight sets your body clock.
from Built from Greek parts: 'photo-' from phōs (light) and 'biology' from bios (life) plus -logia (study of).
