Sorry I missed your post AJ.

Heat stroke is an body getting too hot with inadequate water to work properly. It can be very serious.

The solution is to get hydrated and cooled down. Medical help is needed in the severe cases. You did not experience heat stroke. If you had, you would not have been able to post to NeuroTalk. You would have collapsed.

It sounds more like you suffered from dehydration and heat exhaustion. Again, the solution is getting hydrated and cooled down. Dehydration causes the blood to get thick and provide less than optimal blood flow to the brain.

With your conditions, you need to be disciplined to not put yourself in these situations by letting yourself get dehydrated and do physical exertion in the heat.
