Stress and the immune system – Part 2

In part 1, I gave an overview of the immune system works.  In this post, I want to explore the impact of short-term stress on the immune system.

The immune system is actually very flexible and naturally responds to challenges in your life which means stress modifies our immune system.

When we consider the impact of stress on the immune system, we need to consider the duration and course of the stress i.e. how long it will be present and whether or its continuous or not.

1. Acute Stressors – last only minutes e.g. public speak – can cause adaptive up regulation of natural immunity and down regulation of specific immunity.  This means you have an increased ability to fight infection but reduced specific response.

2. Brief Naturalistic Stressors – for example taking exams, present a short-term challenge – this means you specific immunity is preserved but less ability to fight infections.

In summary in some circumstances, acute short-term stress is part of everyday life, and under some circumstances it can enhance your immunity.

    I am always interested in all form of research on complementary therapies and a report that is supressed piques my interest even more because it makes me wonder what is says. Way back in 2012, Australia’s National Health & Medical Research Council completed a report based on 55 studies into the effectiveness of homeopathy to treat

    • Fibromyalgia
    • Otitis media (middle ear infection)
    • After effects of cancer treatments
    In 2012 the report was blocked from being published.  A campaign that attracted more than 75,000 signatories and numerous Freedom of Information requests including from the Australian Senate finally had an impact and the report has been published. So, what did such a controversial report say?   It found “encouraging evidence” that homeopathy was an effective treatment for:
    • Fibromyalgia
    • Otitis media
    • Postoperative ileus (blocked intestine)
    • Colds
    • After effects of cancer treatments including chemotherapy

    With the Coronavirus outbreak, I thought it would be beneficial to discuss how stress impacts the immune system. The immune system’s job is to keep the body safe and its very flexible but can be compromised by age and illness. There are two types of immunity:

    1. Specific immunity
    2. Natural immunity
    Specific immunity is a slower response than natural immunity as it may take several days.  This is about recognition of a particular antigen (e.g. virus) and the production of a cell that specifically recognises this antigen.  This may come from having seen that antigen before via a previous illness or via vaccination. Natural immunity is an all-purpose reaction that may have a short time frame (minutes to hours).  You will have experienced natural immunity when you have inflammation or a fever or had a wound that has healed.    As part of natural immunity, we produce killer cells that respond to viruses etc. As coronavirus is a new virus and there is currently no vaccination, we are reliant on natural immunity to protect us.
