Immune Resilience: 5 Ways To Achieve It

[lwptoc hierarchical=”1″ numeration=”none”]

Welcome to my blog on immune resilience.

You may like to check out my blog Microbiome Resilience too.

If this information resonates with you, and you would like to dive deeper into resilience then check out my webinar Immune Resilience, which also forms part of my 6 month program The Resiliency Program.

What Is Immune Resilience?

There is evidence that immune processes influence resilience. In general, resilient individuals have a different immunophenotype from that of stress susceptible individuals. It is possible to render susceptible individuals resilient and vice versa by changing their inflammatory phenotype.

Immune resilience is the capacity to maintain good immune function, called immunocompetence, and minimise inflammation while experiencing inflammatory stressors.

Researches have found that during aging and when experiencing inflammatory stress, some persons resist degradation of immune resilience.

6 Characteristics Of A Resilient Immune System

In her great book Immune Resilience Romilly Hodges details six characteristics of a resilient immune system:

  1. Extremely responsive, able to ramp up and down rapidly.
  2. It’s a great communicator.
  3. It can distinguish friend from foe.
  4. It never forgets.
  5. A little bit of a bad thing does your immune system good.
  6. It neither burns the candle at both ends, nor lets the fire grow too big.

Stress: A Deal Breaker For Immune Resilience

Exposure to recent and chronic stressful life events has repeatedly been shown to increase an individual’s risk of developing clinical illness following inoculation with the challenge virus.
The association increases with increased duration of the stressful event, and is most apparent for those experiencing interpersonal or financial events.

Chronic stress interferes with the body’s ability to turn-off the immune system’s production of inflammatory chemicals; and this failure in regulation (maintaining a proper level) of inflammatory response occurs because chronic stress results in immune cells becoming insensitive to cortisol.

Signs Of Low Immune Resilience

Some of the signs of low resilience we explore in Immune Resilience Webinar include:

The last point is a very common experience with my clients. They suffer with a chronic dis-ease, but they never catch the bugs going round their community. In these kind of circumstance, it is NOT a sign of a resilient immune system.

Immune Resilience Supports Overall Resilience

Peripherally occurring immune responses modify brain functions.

In particular individual differences in the innate immune system can impair resilience in face of social stressors by compromising integrity of the blood-brain barrier.

Both human and animal studies show that immune mediators are able to influence the way the brain processes information and responds to it both physiologically and behaviourally.

An example of this is something called sickness behaviour. When we get sick we may have a tendency to want to withdraw – we stay in bed under our covers, or station ourselves on the couch reluctant to leave the house, engage in socialising and generally want to be alone. This is an evolutionary conserved protective mechanism, driven by pro-inflammatory molecules called cytokines. Back in the days when we were hunter-gatheres living in small communities this response (withdrawing from socialising) would have protected our community from the bug – we would gone and hid at the back of the cave (so to speak) until we felt better and weren’t contagious anymore.

5 Ways To Build Immune Resilience

Personal Control

A range of psychological factors may play protective roles against the deleterious effects of stressful events. One of these is personal control.

Personal control is defined as “beliefs in one’s ability to influence circumstances and attain goals.”

Greater perceived control may reduce the perception of threat when appraising stressful events, as well as promote more adaptive coping responses (e.g., problem-solving, support-seeking).

This may, in turn, reduce the severity or chronicity of negative cognitive and emotional states, as well as stress-related physiological alterations.

Develop Your Emotional Intelligence.

Recent compelling evidence has shown that the emotional and immunological systems share more than a similarity of functions.

A recent meta-analysis investigated whether the five basic personality traits—often referred to as the “Big 5” personality traits (openness to experience, conscientiousness, extraversion, agreeableness, and neuroticism)—have specific immunological features or defined susceptibility to immune disorders. The study has shown a consistent association between conscientiousness and a reduced inflammatory response, as judged by the lower level of C-reactive protein (CRP) in subjects with this personality trait. Ground-breaking studies by Steve Cole and colleagues have further supported this concept and shown a specific association between the Big 5 and unique patterns of gene expression in whole blood.

Support Mucosal Immune System

The mucosal immune system forms part of our gut barrier and can be considered one of our first lines of defence. We can evaluate our mucosal immune system with a comprehensive stool test such as The Ultimate Gut Health Test from Healthpath. Amongst many other things it assesses for secretory IgA.

Secretory immunoglobulin A (SIgA) provides a window into the strength of our mucosal immune system, which can pave the way for targeted natural interventions which help to improve overall immune resilience.

Expressive Writing

Research shows that expressive writing can improve immune function and other health measures. For example, one study found that participants who wrote about a stressful or traumatic event for 20 minutes a day for three days had stronger immune systems six weeks later. Benefits include:

Exercise

Irrefutable evidence supports the importance of physical activity, exercise and cardiorespiratory fitness in…enhancing the immune system, healthspan, longevity and resilience.

Therefore, the communication between the skeletal muscle and the immune system seems to be very intense, finely tuned, and dependent on many different factors, such as the ones described above. The tight balance among them provides a proper environment not only for the skeletal muscle repair but also to improve immune system function and responsiveness.

Sleep

Sleep and immunity are bidirectionally linked. Immune system activation alters sleep, and sleep in turn affects the innate and adaptive arm of our body’s defence system. Stimulation of the immune system by microbial challenges triggers an inflammatory response, which, depending on its magnitude and time course, can induce an increase in sleep duration and intensity, but also a disruption of sleep. Enhancement of sleep during an infection is assumed to feedback to the immune system to promote host defence. Indeed, sleep affects various immune parameters, is associated with a reduced infection risk, and can improve infection outcome and vaccination responses.

Concusion

In The Resiliency Program, and Building Immune Resilience Webinar, we dive deeper in to these, and discuss many other ways of building immune resilience.
