It's a hypothesis, but one with a reasonable premise.
 
Years ago someone in your situation (hot area) made large sleep boxes with
baffle entries and sheet covers for the entries to reduce light but leave
enough air-circulation.  If really hot you might also consider a baffled
"chimney" for heat to escape through; even one 90' angle should reduce the
light influx, whether you are using hard materials or soft ones.  If hard
materials, I have known of people who put in tiles on floors to help
ferrets lose excess heat.
 
Glueball did a fine thing two days ago.  I was in the bathroom (Yes, our
ferrets know what happens in there.), and Glueball had given up on joining
me and instead visited Steve in the living room.  Steve asked her where I
was and she dashed over to the litter pot, pointed to it, jumped in and
(not using it) and stared at him.  He broke up.

Try times-out in a non-fun place (even if that means short ones in a carry
cage) in case she is a bit bratty about possessions but ALSO get her a
dental vet-check.  I've seen things like this with dental eruptions errors
(such as a retained baby tooth causing an abscess).  Face shortness as
some individuals have can also made dental eruption harder and lead to
"chewier" kits from some breeders.  A retained deciduous tooth is a
possibility if one got trapped between erupting adult teeth.
