How to avoid sun stroke
 

Yesterday it was like 90 out-- i went for a 2 hr ride and was pushing pretty hard--although i was constantly hydrating myself, i think i must have gotten sun stroke, as my body has been scorching hot since i came back, and i've been dizzy and natious. How do you serious riders avoid sun stroke---would wearing some sort of bandana or beannie under my helmet help?

Sunscreen and hydration. That's pretty much it for me.

Second that. Sunscreen and lots of water is just about the only way to do it. I ride hard though 95-100 degree weather and the only thing that'll get you through is lots of water. I'm talking two 24-32 ounce bottles. Get a light mesh jersey instead of the regular spandex.

If you feel that you are getting too hot dump some water over your head and down your back. Carry a bandana in your jersey pocket to wipe sweat. It works better than the terry on your glove.

We (most of the USA) had a rather cool spring. We appear to be going head-first into a hot summer. I've noticed a heat acclimation problem myself over the last week-- I have trouble with finishing my runs.

I think that it will simply takes a few weeks to get used to it, in the meantime take it easy and drink regularly.

I find that a good helmet visor keeps some of the heat off your face. If you get heat stroke, even with enough water you still may need to find shade or a cool place to lower your temp. Also take it easy if you need to. The water over the head is helpful.
