Why do our brains release these ‘chemicals’ that make us not afraid in our last moments?

731 views

I’ve heard of people with near death experiences having these calm, soothing experiences. It’s lovely that our brains do this for us.
I know there’s a natural selection, those with the best characteristics continued, and those who didn’t have the qualities to survive would pass away. But everyone dies in the end. What made it so that all brains release those chemicals to ease our last moments?

Since it’s not something that would impact reproductive chances I’d say it’s not something that was evolved or selected.

More likely a result of lack of oxygen to the brain that thus shuts down nonessential functions first.
