I always love this question.
Can it be a problem?
Well, can one die someday?
Yes we can but are we going to die over the thought of dying?

In Florida, my humi runs around 77 year 'round.
It has been that way for over 12 years now that I have lived here.
Maybe I am lucky but I have never had a problem.

Next, ask my dad what did he do to cool down cigars when living in Cuba.
Answer: Nothing. They didn't have a/c.

In summary, can it be a problem and with modern knowledge, do we know better? Sure, but it doesn't mean we are going to die.
