Well, no. Our minds often do, however. At Nature:
In a well-known condition known as ‘broken-heart syndrome’, an extremely stressful event can generate the symptoms of a heart attack — and can, in rare cases, be fatal. Conversely, studies have suggested that a positive mindset can lead to better outcomes in those with cardiovascular disease. But the mechanisms behind these links remain elusive.
[Asya] Rolls is used to being surprised by the results in her laboratory, where the main focus is on how the brain directs the immune response, and how this connection influences health and disease. Although Rolls can barely contain her excitement as she discusses her group’s eclectic mix of ongoing studies, she’s also cautious. Because of the often-unexpected nature of her team’s discoveries, she never lets herself believe an experiment’s results until they have been repeated multiple times — a policy that [Hedka] Haykin and others in her group have adopted. “You need to convince yourself all the time with this stuff,” Rolls says. – Diana Kwon (February 22, 2023)
The study subjects in Rolls’ experiment were neglected mice. Mice have feelings, just like humans. What they don’t have is intellect and free will.
But even in a mouse the mind apparently matters.
You may also wish to read: Yes, the placebo effect is real, not a trick. But the fact that the mind acts on the body troubles materialists. Such facts, they say, require revision.
One Reply to “Our brains “control” how sick we get?”
I once pointed out to a head of department in an academic setting that religious people live longer.
His reaction was immediate and negative. No way he said.
But research proved him wrong. It was not just a better life style but much better attitudes. The ones with the more positive attitudes were the ones living longer.
