Standing naked without fluid at room temperature could kill you within a day or two, I'm suggesting a temperature almost double that, with strong sunlight.

You can generally last three days without water in normal conditions, and 40'C with sun isn't really that extreme either if you're being still and not exercising or walking around town.
I wonder though, does dry or humid air dehydrate quicker?

3 days is about the absolute maximum for the average person, many won't even make it that far. I assume dry air will dehydrate quicker, so that's also an important consideration.
How long would you have to stand naked in open sunlight at 40c before you die of dehydration?
Doesn't really matter that much if you're lying in 40C sunshine or in a -20C snowpack. You stop sweating when your body water gets too low and your body goes into emergency mode. After that it goes to survival mode. Same with cold, your muscles stop generating heat and goes into emergency and then survival. You die of Hypernatremia (heat), or hypothermia (cold).
It is said to be a very gentle way to die, as in either case you lose consciousness before the vital organs shut down.
Depending on the circumstances this can take from three days into a week.
Really? I've been outside in short sleeved t-shirt for an hour in 0 °C and the only thing that happened was that my hands got a bit slower.
That shirt makes a helluva lot of difference, and I assume you had some sort of jeans or other pants on. Being absolutely naked and standing still is a completely different thing. I had merely two layers on talking to a neighbour still for 25 minutes in -5C and I had very strong and unpleasant freezing symptoms in the body after that (Nov '14).
One can test their emergency mode by staying awake. 3-4 nights with 2 hours of sleep a night and being active during the day will probably trigger it.
Your heart rate will rise quickly, you start to lose your short-term memory and your appetite rises. You will feel dizzy at times, but eventually you are so tired that you don't feel tired anymore. And that is a blessing, as you don't care anymore.
It's not something I recommend, but I experienced it twice in the military. You go on autopilot and don't care a sh*t about the weather, fatigue or anything.
