#244 How Immunity is influenced by the Mind with Dr Monty Lyman
The Doctor's Kitchen Podcast
Mind-Immune System Interaction and Evolutionary Survival Strategies
During acute stress, the brain communicates with muscles to recruit immune cells, activating the immune system's antibacterial elements like neutrophils to prepare for a potential threat. This showcases a preemptive signal to defend against infections during fight or flight responses. Conversely, when infected with a virus or bacteria, symptoms are mostly mental, inducing sickness behavior where individuals isolate themselves. Studies suggest that humans can detect infection in others by subtle cues like biological motion or even body odor changes. This mind-immune system interaction showcases an evolutionary survival strategy where the immune system recruits the mind during infection, emphasizing the interconnectedness and adaptive nature of the defense system in optimizing for procreation and survival.
