I am alive, life on a island with very high humidity, since 30 years.,.
Well of course you're alive. High humidity never killed anyone. The question is, are you comfortable?
I can recall times sans A/C when I lived in the deep south where I needed to place a stack of bath towels next to my bed just to make it through the night without sweat soaking into my mattress. Not good. It was too hot to sleep.
