You need an attic fan...Kept the (screened) window open all night in our bedroom tonight. Outside temp 52F now. Thermostat set at 55, irrelevant. Room still at 75!
And I’m up as the birds are up at this hour, little chicks chirping for bugs from their mamas and more melodious birds in the distance calling out their songs.
Window now closed. Hopefully I can snooze some more.
