Most problems are K or potassium
all foods we eat that are processed have to much sodium, the problem lyte is K or potassium, when we run low on that are bodies can have problems with muscles cramps and Abnormal heart beat. and calcium and Magnesium are critical for muscle function. We need to invent a Bicycle related Stevia based beverage
that has more K,than NA, Ca, Mg now that would be the ideal drink
SO I also like the non-glucose hydrating powder you add to water most have 3 times the sodium to K except for a few sold in running stores I forget their name and they have the new natural sweetner(Stevia) thats considered to be safe where many of the diet drinks actually have a by product that can be toxic or carcinogenic. and that gatorade has way to much sugar that can make you puke or gain weight..

signs and symptoms of heat problems.
Finally once you have had a sever episode of over heating people tend to reoccur more easily, it was so bad
when I worked in a dispensary at Paris Island they would discharge a young marine if he ever had a sever occurance of heat stroke due to the fact ,some people overheat easily and tend to have reoccurance of problems in high temps.
Think of a marine in battle gear in the desert wearing a gas mask for a couple hours.
