This is the only thing that works for us: Whoever wakes up first, makes sure that all the curtains & blinds on the south side of the house are closed (and they stay closed until late in the evening when it's cooled down); all the windows on the North side are flung open, together with the garden doors (we have a north facing back garden) to let in as much cool air as possible into the house for the day ahead - they stay open all day. Lots of cold drinks (including iced coffee - yum); light meals (yesterday I had an ice cream for lunch - that's all I wanted) mainly salads - very cooling; wear as few clothes as you can get away with; regularly splash faces with water and let dry naturally. If I start feeling uncomfortable, I run a cold tap over my wrists (palm of the hand upwards) which helps. One day, I put my feet in a bowl of cool water - bliss. Cool shower before bed. And, sadly, hubby is in the spare room at the moment as we are too hot to share a bed! (A friend puts a pair of cotton socks in her freezer a few hours before bed and then puts them on when she's ready to try to sleep - she swears by it).
