Why is a heatstroke primarily dangerous to people?

Heatstroke is primarily dangerous to people because it occurs when the body's temperature regulation fails, leading to an elevated core temperature that can damage vital organs and systems. The body's inability to cool itself can result in severe dehydration, confusion, seizures, and loss of consciousness. Without prompt medical intervention, heatstroke can lead to permanent damage or even death. Vulnerable populations, such as the elderly and those with pre-existing health conditions, are particularly at risk.
