Eh, not as much as you’d think. The back of your neck near the brainstem is crucial to temperature regulation. That’s why the go-to advice to alleviate heat stress is putting something cool like a wet towel around your neck. During midday when the sun is highest, keeping the sun off the back of your neck may well keep you cooler than keeping it off your face. Using your hands to shield your eyes occasionally looks a heck of a lot less dumb than keeping your hands up to shield the back of your neck.
Moral of the story, baseball hats are great for watching baseball, where you’re sitting facing one direction the whole time and can orient them accordingly. For general outdoor work, a sun hat with a neck flap is waaayyy better.
