Do you warm a telescope?

Hi all,
it might be a stupid question to ask here, but since i never had a telscope
before and since i am planing to buy my first now so i might ask this...
why do you need to cool a reflector ( and not a refractor)??
Thanks for the answer

Here's the opposite question. Do you warm your telescope? I live in the
mid-Ohio valley. It's not as hot as a desert but there is some humidity. By 10
PM the temperature is 85F and the dew point is sometimes as high as 72F. This
is just under the temperature of my basement where I keep the telescope. It
seems there's a chance condensation could form if I take the telescope
straight outside from the basement. Perhaps I could use a room heater to warm
it up some first.
