Having worked in the Southwest for awhile and occasional summer Houston job also I thought I could acclimate decently to the humidity of Kansas summer, not so much. Last job was down in a gravel pit in full sun standing in water. Truck dash said it was 108 F at 4 PM and probably very high humidity. Umbrella, long sleeve shirt, some special wicking under layer to help keep sweating, a cold water neck thing, cool water. none of it seemed matter, just too hot to be working for any length of time. So what do you guys do not to keel over with heat stroke. Company has had several people get heat sick this summer.
