In the U.S. workers in Western States often work at night from around 10pm to 6 am when it's 120 degrees Fahrenheit out during the day

 However, more traditional cultures might not bend in that way even though Americans in desert states like New Mexico, Arizona, Nevada and California have done this sort of thing for outdoor workers now for decades whenever possible to save lives.

For example, in Palm Springs during parts of the summer it might be well over 120 degrees up to 125 or 127 degrees. This usually means that by midnight it is down to around 100 degrees with the low of 95 degrees or 100 degrees by dawn. When the sun isn't out it's easier to work without getting sunburnt too which increases your heat in your body somewhat too.

So, one way to save lives is to work at night but also that might mean electric lights because it's night too and that might be more expensive in India than it is relatively speaking in the U.S.
