heliophobic
Averse to sunlight
Heliophobic describes an aversion to sunlight.
In biology, heliophobic organisms avoid or cannot tolerate direct sun exposure—certain plants, fungi, and bacteria thrive only in shade or darkness.
The term also applies to people who shun sunlight, whether from medical conditions like photosensitivity or simple preference: She's practically heliophobic—always drawn to the shadiest corner of the patio.
