To whom it may concern but it doesn't , except as a vector to post nonsense:
Extreme heat can be fatal due to several mechanisms. The most direct is heat stroke, where the body's thermoregulatory system fails, leading to dangerously high core temperature. This can cause organ damage, especially to the brain, liver, and kidneys.
Dehydration from excessive sweating further reduces blood volume, straining the heart. Cardiovascular collapse and arrhythmias can occur. Vulnerable populations—such as the elderly, infants, or people with cardiovascular or respiratory conditions—are at highest risk.
Additionally, pre-existing chronic illnesses can be exacerbated by heat stress, leading to multi-organ failure.
Statements like, "But they would have died anyway" are of course completely true, they would.
But they wouldn't have died YET.
I don't know what characteristics make people say that sort of crap, but any of being thick, ignorant, arrogant, lazy, obdurate, uneducated, a troll and that, would do it.
The same list applies to those who try to claim that climate change is not being massively propelled by human activities.
Educate yourself or STFU because you're being a tit.
