here? no

overseas? maybe

one thing to take into account is that you need not just silica gel but a hygrometer , which you need to monitor that the guitar stays around 40-50% ish humidity

the good part about it is, due to our relatively stable weather, half the time you dont have to worry about it and majority of the time the worse case scenario is you get a bloated top.
dry is actually worse,

in general comfortable surroundings is the best, as long as you are comfy, the guitar will be fine

once the heat goes up and you feel too hot or too try that you feel like you are getting sore throat, then its bad

its not as simple as that

basically the first question is, is it a laminate or not?

if its laminate, then you can not worry about it, they are quite resilient

if its not, then you need to read the manual, what are the right conditions for the guitar

for most cases its no a problem (I've never seen guitars go bad due to weather here), but theres no harm just double checking
