Heliophobia is the fear of the sun, sunlight, or any bright light. Could be considered abnormal, irrational, extreme.
I’m in a coffee shop sitting by the window looking out at the trees at a park. It’s rare to find a coffee shop with a park view or anything more than buildings.
Even though it’s impossible for the sun to shine directly in the window, other customers come in and pull the shades down to avoid any chance of direct or indirect sun. This is the norm in Taiwan.
They try to pull my shade down but that’s not happening as long as I’m sitting here.
