I actually over-hydrated once after a hot weather run and ended up in the ER and then the hospital overnight with an IV electrolyte drip in my arm.
Large quantities of plain water flood your kidneys and wash out your body salts. You’ll end up vomiting and getting even more dehydrated plus your blood chemistry will be totally messed up. People die from this.
You have to pour gatorade down to stay hydrated.
Exactly!
I try to warn folks all the time about water drinking.
I drink v8, then take electrolytes in a pill form while doing my extreme motorcycle riding in the woods, desert.
Do they still take salt tablets?
Perspiration works on the principle of osmosis. The sweat glands push sodium out and water follows. Water evaporates and cools leaving salt behind. Salt is not reabsorbed leading to hyponatremia. Heart rhythms and neural impulses depend on a balance of sodium and potassium. When sodium is depleted the balance changes and potassium becomes excessive. This is the condition of hyperkalemia. Potassium is an ingredient in euthanizing agents for expired pets and executed criminals. There is only one way for the body to eliminate excess potassium and that is by vomiting. That’s why feeling sick is a good indicator of hyponatremia. The solution is to eat a salty snack.
I keep the equivalent of 1 gal of Gatorade powder in my pack when hiking. I’ve used it a couple of times when it got hotter than expected & I still had 4 miles to get back to the car.
