Heat stroke often causes hypovolemia. I really shouldn't have to find this info for you. It's common sense that heat stroke leads to organ failure. For someone pretending to be smarter than everyone else, you sure seem to be kind of a

It's very odd to say that heat stroke causes hypovolemia. Hypovolemia is often actually a significant a contributing factor when heat exhaustion is developing towards heat stroke, which is the opposite causality.

Excess sweating and inadequate fluid/electrolyte replacement, when combined with vasodilation in effort to keep cool, result in inability to regulate blood volume. Aldosterone secretion would typically result in retention of sodium and water, increasing blood volume, maintaining healthy blood pressure within the dilated blood vessels. But the salt and water aren't available, blood volume can't be increased, and blood pressure drops low enough to where you are unable to pump blood to the body (hypovolemic shock that isn't due to hemorrhage).

I don't know why you linked to that abstract. The abstract does not say that hypovolemia is a result of heat shock. As explained above, it's a contributing factor that can result in heat shock. Which is why not everyone with elevated unregulated body temperature will also have hypovolemia: because it can happen without dehydration. For example, when the wet bulb temperature is above 35 C the human body is unable to lower body temperature. If you are replacing fluid and electrolyte you will lead to heat-induced death without hypovolemia.

Side note, aside from the abstract (which didn't even support your claim), everything else associated with the citation is in Hebrew so i doubt your corroborating evidence is there.

Thank you everyone for coming to my Ted Talk.
