comment Can too many electolyte supplements be dangerous?
@DanielRHicks No, what the thirst mechanism tries to keep constant is not plasma volume, but electrolyte concentration. Drinking to thirst will not lead to hyponatremia. You become hyponatremic if you overdrink, i.e. if you drink when you are not thirsty, because Gatorade told you you should. But read the links, they are full of actual field data from grueling ultramarathon events.

@DanielRHicks Because you lose more water than salt through sweat, so the concentration of salt in your bodily fluids is not reduced, but increased. It's concentration of electrolytes in your blood that triggers thirst, so if you drink according to it, and not to a made up plan, you will never have dangerously low levels of electrolytes. For most people, electrolyte levels will be fully replenished in the next couple of meals.

comment Fixie Vs Urban bike for small-distance commuting
I would argue that the possibility of controlling speed without touching the brakes when maneuvering at low speeds actually makes it a better choice for traffic. The only inconvenience is not being able to reset your pedals to get on the saddle again after stopping without lifting the rear wheel first, but that hardly qualifies as a hazard.

comment Can too many electolyte supplements be dangerous?
@heltonbiker From the fourth article linked "body fluids have a sodium concentration of 140mM while sweat has a value of 20-60mM. Therefore when you remove a liter of sweat from your blood, it has much more of an effect on the volume compared to the solutes (sodium), and what happens is that the osmolality rises in response to sweat losses." You really don't need any more Na, unless you are overdrinking. Things do get more complicated if you are also drinking, not eating, the calories to prevent bonking. But you could replace your salty sticks with gummy bears with little electrolyte risk.
