Someone gave a tip here a few weeks ago. It was to spray your T-Shirt with water from a sprayer.
It really works, or at least it takes the edge from the heat. I'm also getting extremely tanned; even wearing factor thirty. That's not good; skin cancer time.
I've also been bitten twice by a horsefly (I think). I'm all purple and swollen around the bite area and it's pretty uncomfortable; particularly when I'm sweating and the sun is burning the sore/itchy areas. Poor me.
Our work is 95% residential so I can't start too early, but we've done all we've planned to do, but it's been a struggle - for me anyway.
Anyway, after another swealtering day 'on the windows', Wor Lass finished work yesturday, then went for a several mile run - part of which must be about a mile solid up-hill. Then she went to running club to assist with organising a race.
Being fit helps you acclimatise quicker; unfortunately I'm not!
