It’s wise to have a small toaster oven if you absolutely need to cook something. They preheat fast and obviously put off less heat than a full oven. I don’t really bother with the oven much these days as it’s getting over 110 here at the moment. Also cook after the sun sets
As European where AC are not common: Close all windows and window shutters during the day. And don’t use the oven.
