When the body get dehydrated it looses essential minerals including sodium, potassium, calcium bicarbonate and phosphate. Gateraid has sodium, potassium and phosphate in it to help replace those lost. In most cases you can prevent dehydration by eating right and drinking plenty of water. Taking a multivitamin with these minerals can help too. In a recovery position where you are already dehydrated then gateraid can be helpful in restoring you. I have dealt with heat stroke more than once when I did roofing jobs. It was impossible to remain hydrated even when drinking gallons of water. Gateraid helped me recover faster - especially after throwing up. The first time I suffered Heat Stroke the Dr told us that the body can completely absorb a tablespoon of water every 3 minutes. If you do end up with heat stroke it is not a good idea to guzzle the water. Sipping it constantly and finding a way to outwardly cool your body is the best route. If you drink too rapidly you will throw up. Also taking salt tablets can help or you can drink gateraid.
Yes there are sugars in gateraid and your body has to filter the "impurities" out of the water before it can use all of it. It might be good to alternate between plain water and gateraid.
Gateraid can be good for your body but only when used in moderation and used properly. Take care of your body and you don't really NEED gateraid.
