Just thought I'd share this idea with you all if haven't already got one or two . We bought ceiling fans for every room in house after the initial one in the bedroom and must say they have been a Godsend especially through the night . Strangely enough the most expensive one is the noisiest ! If you decide to try them get the Argos basic one £20 it's easy to fit and I'm very susceptible to any little noise when trying to sleep but I have it on all night on low which means I can have windows closed thus shutting out any outside noises and have slept much better and cooler. Maybe work for others too suffering those same hot episodes.
