Fingers crossed for sleep tonight🤞

I am not going to moan about the glorious weather but sleep had been a challenge!

I have shut windows, closed curtains and blinds during the day then opened windows after sunset, yet the upstairs of our wonderfully energy efficient home still feels like a sauna.

We sleep on Egyptian cotton sheets with an empty Egyptian cotton duvet cover and have an Airblade whirring all night and still we are sweltering.

Are there any tricks I am missing?

Praying the Easterly breeze will bring respite tonight.
