Phoenix resident here. I find that in summer I need to limit my caffeine and get plenty of sleep. I buy Nuun electrolyte tables for runners and drink them all day in my water while just sitting in the office. Get your AC looked at, make sure your duct work is not leaking any air. It is kind of expensive but I installed a mini-split AC just for my bedroom and it is incredible. I highly recommend a mini-split (or ductless ) AC for the room you sleep in.
