I don't much mind the heat generally myself but so many people are discussing the best ways to keep cool and I see advice to take cool showers all the time
I've posted this advice before but I think it is worth repeating. If you want to feel cool in a hot environment in a way that lasts longer, take warm ( or even hot if you can bear it) showers and baths
This is advice I was give by family who live in a climate that is constantly much hotter then ours and who don't have air con . I. have found their advice effective and always take a hot shower before bed on hot nights. When I get out of the hot shower, my bedroom seems to feel cool even if it in fact very warm in there and I don't start sweating again right away like I do after a cool shower.
I was pleased to see that this advice is backed by science

Just though it may be worth a try if you are finding it too hot to sleep in the next few days
