I never really appreciated air conditioning until I visited Bangkok, a city of where the heat is often just too much to handle. I could never imagine there was a place where the outdoors could be as thick with heat as it is indoors in the UK. It is so strange to leave shopping malls that are cooler than the street outside – much cooler. It’s like walking from the outside to the inside, not the other way around.

The air conditioning of some of the hotel rooms was very impressive, giving plenty of relief from the constant, exhausting heat. But if you move down the scale of accommodation, then you unfortunately find that the air conditioning units are equally down market. The efficiency of a hotel air conditioning unit is far better than the flimsy fan you get in a £2.50 room down the Khao San Road. It can barely cool the hairy chin of the nearest blood engorged bed bug sitting on the ceiling.
