heatwave support?

I live in New England and it's been above 100 degrees with crazy humidity for the last three days. I've been basically inside, AC on and horizontal the whole time because when I'm not I keep getting hit with waves of really intense dizziness/lightheadedness/hot flashes shaking etc.

I've been in remission on tremfya for about 9 months and never felt like this. 1) have others experienced heightened heat insensitivity w UC or Tremfya? 2) any tips? i'm trying to eat a lot of protein and drink a lot of water and stay cool but it doesn't seem to be making a difference....
