Why do they say to avoid the sun between 10 and 3 (or 11 and 4 daylight savings time)? Shouldn't the hours be symmetric about noon, when the sun is at its peak?

Noon isn't the midpoint for the day though. Take for example at the height of DST the sun rises around 0500 and sets at 2100. Rise to noon is 7 hours noon to set is 9 hours. Same for non DST. Rise happens at approx 0700 and sets 1900. Rise to noon is 5 hours, noon to set is 7 hours. 

TL;DR 10 to 3 (11/4) **is** the apex (albeit a bigger sampling), not noon.
