Heliophobia is a phobia in which the sufferer is afraid of sunlight. People have it for a number of different reasons. Some people have it because of
traumatic experiences with sunburns or cancer, scared they will get bad sunburns or
skin cancer. Some have it because they are scared of the sun crashing into Earth. I, myself, have the phobia because of the second reason.
For heliophobes, they LOVE
cloudy days, due to no sun. Some hardly go out, and others don't go out at all. It differs.
