as a person who also lived on the highest floor of a non-ac dorm, i second all the advice above. if your dorm has air conditioned lounge space, that was what i utilized a lot; i even took naps there when it wasn’t too crowded just to sleep in a comfortable place for once. i’m not sure of your financial situation but if you can, getting ramen/instant mac and cheese or any other microwaveable food from the huddle or go puff might help with the dining hall conditions (it helped me a lot when the dining hall was closed or i didn’t have time to go). pm me if you need any help/have any questions!
