Why does the sight of blood etc make people feel sick, seeing it not suffering an injury?

Interested to know what causes that reaction. Not the person suffering the injury but people who see it. Doesn’t affect all people and you can get desensitised but what is it about the sight of inside stuff that makes you feel sick?

My husband is really bad with blood and gore, not just in movies, but in real life as well. It makes him super queasy and weak in the knees. It’s, as is the case for most people, just other people’s blood, not his own.

I’m assuming it’s some primal thinking like “Blood’s not supposed to be outside of the body”, and it triggers some fight/flight instincts when it is, especially in large quantities.

I’m not affected by blood and gore at all. In movies I don’t care even a little bit, because it’s obviously fake, and often so exaggerated that it becomes laughable instead.

In real life, I tend to disassociate and turn into a robot when faced with traumatic experiences and just operate very methodical until the worst is over, and *then* I sometimes get lightheaded and shaky.

Interestingly, I don’t mind seeing bloody injuries, but a broken bone and a body bent the “wrong way” turns my stomach. It’s like, a compound fracture makes sense to my brain. The bones broke the skin, so obviously there’s blood now. A broken arm or leg with skin intact just makes my brain ring all the alarm bells because “Aaaaahhh, it’s not supposed to go that way!!!”

The human brain is fucking weird.
