No I have not - except a tiny desktop usb fan.Have you invested in a fan?
Very useful, if rather redolent of those TV programmes based on the short stories of Somerset Maugham I saw as a child where fans were always slowly whirring in the ceilings and the air outside was thick with the sound of crickets.
Given the increasing frequency of heatwaves it would be a good idea and I actually find the sound soothing at night - I even have some relaxation/sleep apps with fan sounds among others.
