Hot weather

Hi, i'm not sure if many of us realise that the weather in sg is hot. Unless some of us has a aircon at home, but during the night i feel quite hot eventhough already switch on to the highest number, i'm now 6 months plus pregnant is it ok to shower at night roughly 9 pm and above? Old people mentioned, pregnant mum not good to bath in the middle of the night.. just need some advise. As we live in the different Era. Thank you.
