I've got the same problem you do. I get intense headaches in the heat, black spots in my vision, etc. It doesn't help that I currently live in virginia, otherwise known as satan's taint. I'm ****ed if I get stuck in traffic (what, me lanesplit? neverrrrrr
)
Some suggestions:
- mesh gear with upgraded armor (revit airwave pants + revit tornado jacket currently)
- white gear whenever possible, especially helmet
- underarmour shirt; if it's really bad, literally dunk it in cold water before putting it on, or put it on and toss some icecubes into it
- camelbak of some sort, hydration is suuuuuper important
- wet bandana around neck
- motorcycle specific cooling vests, or this crazy thing here:

- ride very early in the morning, I did this all last summer (before getting a job with regular hours...)
ALWAYS COVER YOUR SKIN. It might seem like putting anything on yourself when it's hot will make it worse, but direct sunlight will **** you up in no time - you will dehydrate and get heat stroke much faster. This is because your body cools itself by evaporating your sweat with its own body heat - but when the sunlight is directly on you, it does that before your body can, so your temp just goes up and up and up while you sweat everything out to no avail. Plus the sunburns, ouch.
Here's a simple article to help.

As one hot blooded person to another - wear your gear. Otherwise you'll expose yourself to much worse risk of injury, without any benefits to keeping cool.
