Do we fully Understand How our Immune System Really Works

What Happens when we see a sick person?

 Today morning my dhobi came home with infected red eyes to wash our clothes, my mom  said no to her …when I asked her  why? She shouted at me and said seeing sick people can make you sick too. Is this  true???

I checked it out and found some intersting answers.

It is interesting that the brain may stimulate an immune response, probably from the pituitary or the glia cells directly. That hospital staff have a lower IL-6 response compared to normal people and have better immunity. Why is this? The body can become acclimated to strssful stimuli and constant exposure to sick people might lessen interleukin-6 (IL-6) response over time. What would be interesting would be the hospital staff's ability to fight off infection once acquired. Would a lower IL-6 response (if confirmed) affect their ability to recover from an infection?

Can we make our brain  react better where it says to itself -  “If I see a bunch of sick people, maybe a big infection is around so I better kick my immune system into high gear.”

 Researchers drew their blood, exposed each sample to bacteria and then measured the levels of interleukin-6 (IL-6), which is secreted by white blood cells as a response to stress (sick persons photo) or trauma ( gun shot photoes)  . Although the subjects rated the gun shot photographs as being more stressful than the illness images, but the blood results told a different story. Whereas the gun images prompted a mere 7 percent increase in IL-6, levels of the substance, the sickness photoes showed a  24 percent increase.

 Since the Interleukin-6 is produced by T-cells in the blood, the conditions contributing to the increased Il-6 production in response to bacterial exposure must have occurred prior to the blood being drawn (presuming that showing the pictures only to the blood samples makes no difference) and have been present in the blood sample. But many neurochemicals connect the brain to the immune system

 There was no  any variation of contributing factors, such as an increased number of T-cells or other blood agents, but there must be something else different about the blood that would point to the initial response source.There’s not likely any real benefit in tricking the immune system: there is almost certainly a cost to the immune system response preparation.
