Wilting in the heat

Most of my reading is done on the commute to and from work but at this time of year with the sunshine and heat it's very difficult to read. The rhythm of the train and the humidity make concentrating on the words on a page very difficult and as a result it's been hard to keep the reading pace going.

Don't get me wrong I'm able to sit on a beach or in the garden and read away in the sunshine it's just the elements combining on a hot train that make it so difficult on the commute at this time of year.
