one wonders how it ever even seemed like common sense to disrupt the body's evolved immune response to acute, traumatic soft-tissue injury, never mind good conventional medical advice.

ice to preserve a detached structure? sure. quelling the inflammation of organs or the brain? yeah, those types of inflammation can turn into a cascading collection of responses, often (but not always) having distinct non-traumatic root causes.

but disrupting increased (life)blood flow to the site of acute, traumatic soft-tissue injury? seems like some otherwise logical lines crossed there, not to mention just a bad idea on its face.

That's because the body's initial response is often way out of proportion. I get the flu and my body decides to turn up the heat. There's pollen in the air and my nose goes into lockdown for weeks.

I've dislocated my kneecap a few times and the near-immediate swelling was much worse than the actual injury. Recovery took a few weeks anyway so easing my discomfort for a couple of hours made no difference.

my comment is limited to "acute, traumatic soft-tissue injury", the scope of which excludes viral infection, allergic reaction, and strict joint injury.

The point is that evolved responses don't always properly account for nuance or proportion. If inflammation evolved for large traumatic injury, it may still be triggered for limited soft tissue injuries but then the response could be disproportionate.

Those examples were more about the body's tendency to overdo its response.

(But aren't joint injuries usually soft-tissue as well? It's the ligaments that get the short shaft.)

This is likely because you are deficient in vitamin D.

From what I remember, turning up the heat is an attempt by your body to kill off the virus. This is a natural response, not a genetic mistake.

Our sinuses have shrunk and or airways collapsed far too quickly for evolution to adapt, leaving us highly susceptible to allergies and inflammation. This makes the likelihood of catching a cold or flu much worse. It also makes the healing process longer.

I very much recommend you read Breath by James Nestor if you suffer from allergies. Or at the very least, let chafgpt summarize it for you.
