Manchester was apparently the hottest region last Friday (which is odd since London I would have thought of as hotter), and I couldn't even bare 28 Celsius (81 F)!!! I can't bare heat...which is why I dread to think what I'd be like in America.
Also I sleep in a loft (which you guys call an Attic), which makes it a Sauna. ;~;
i sleep in the same kind of area too
so i feel your pain, but there is solutions
open a window, put a fan infront of the window, if that fan doesnt hit you, get another fan and position it somewhere so it hits you, and that will keep some airflow going. Not ideal like AC or anything, but its better then nothing.
Also, lights create heat, so if you leave any lights on during the day, turn them off and just have a small light on instead
