As temperatures rise across most of the earth, farm workers and others who work outside like roofers, construction laborers, and lawn care employees are being increasingly affected by the high heat stress that occurs when high daytime temperatures and humidity take their toll on those workers, especially if they are doing hard manual labor. One solution that has been used by some people is working at nights when temperatures are cooler and the sun is not adding to the heat stress. But as this article in Inside Climate News points out, working at night provides its own set of dangers such as lack of visibility and split shifts that result in extreme tiredness that can result in injuries. So while working at night avoids someone of the problems with working in hot days, it is not a cure-all.
