It was hot but was it a hardship with the helmet? - didn't notice if it was to be honest.
How very fortunate for you, but different people sweat differently. I know other people who can cycle in a helmet without hardship, my wife for instance, but many who cannot.
I get a sweaty head even when NOT wearing a helmet. When I do wear one, which I do for mountain-biking, I get much more sweaty in spite of having chosen the best available model for this purpose (£90 retail, ventilation optimised for low speed climbing). Sweat runs down my face, into my eyes, drips off chin ... It's all rather horrible - even in cool conditions - but since mountain-biking involves getting dirty anyway and since falls are commonplace on difficult terrain, I tolerate the discomfort.
For all other sorts of cycling, when falls are NOT a common ocurrence (once you've learnt to ride properly) and when I do not wish to get into a muck sweat, I do not wear a helmet.
Fortunately, the one condition in which falls become commonplace in normal cycling coincides with ambient temperatures around freezing point, which is as cold as it needs to be for me NOT to get a sweaty head whilst wearing a very well ventilated helmet. So then I make another exception to my no helmet rule.
And since I bring it with me anyway to keep the Guardia Civil when touring in Spain, I put it on at the tops of mountain passes for the long and fast freewheel down. But it comes off again as soon as the road flattens or when the Guardia is out of sight.
So I can perfectly understand why postal workers would find helmets uncomfortable and beg you to be quietly thankful for the physiological differences that make it not like that for you.
