Immune Health:  Important things to know (pandemic or not)

Immune health has become more relevant this year.  Perhaps more so than ever before!

No matter how you look at it, there are a few core principles to optimizing immune health.  There are also a few specific science-backed nutrients and nutritional compounds worth considering.  Scroll down to learn more.

First of all, our body is a system and should be treated as so.  One size fits all solutions and quick fixes are rarely the answers for good, life-long health and well-being.  Consistent practices that are realistic and strike a balance across all influencing factors can help to support your success and overall happiness.

Within our internal ecosystem, various checks and balances are continuously at play.  Facets of our lifestyle and environments can make or break the health of these systems.  Let’s explore this a little further.

Inflammation & Oxidative Stress Wreak Havoc on Health

Chances are that you have heard about inflammation, but oxidative stress may be less familiar.  Oxidative stress is a tricky thing that happens within our bodies.  This natural chemical reaction can result from environmental, physical, and mental or emotional stressors within our daily lives.  It also triggers inflammation in the body!

Scientists go back and forth, but generally believe that low levels of oxidative stress (oxidative eustress) could help the body to build internal resilience.  Also, this may be a mechanism to treat diseases like certain types of cancer.

However, when oxidation becomes excessive and chronic, the imbalance is too much.  As a result, the body goes into a bit of an overload and can’t handle it.  This is when oxidative stress can contribute to damage to the cells and tissues within our bodies.  It also reduces the body’s ability to defend itself!

Chronic oxidative stress contributes to the onset of diseases and increases the risk of infections.

Agents in our environment and lifestyles, such as pesticides and air pollution, cigarette smoking, and processed foods are known contributors to oxidative stress.  Antagonistic substances, such as high-fructose corn syrup in food or chemicals in consumer products, may contribute further to the havoc.  Also, our body’s response to overloads of psychological and emotional stressors may induce oxidative stress.

In the modern world, it is pretty safe to assume that excessive levels of oxidative stress will be likely and that measures to combat this threat should be taken.  Also, if you have already developed a chronic condition such as diabetes or autoimmune diseases, then paying attention to sources of oxidative stress will be of utmost importance.

Nutrient-rich, healthy eating is one of the best approaches to oxidative stress.  Anti-inflammatory foods and supplements provide the body the antioxidant boost it craves.  Even better to know, the mitochondria in our cells (our little energy creators) are sensitive to environmental factors and oxidative stress yet respond well to good nutrition.

Other behaviors, such as consistent, moderate-impact exercise, managing psychological and emotional stress, prioritizing sleep, and taking precautions with chemicals, may also support the body to combat the negative effects of oxidative stress.

A Healthy Gut and Immune Health are Linked

Gut health more or less equates to immune health.  An estimated 70% of our immune cells reside in the gastrointestinal tract (aka gut), making it integral to our immune system. 

Our digestive organs and gut bacteria play critical roles in our body’s natural detoxification, hormone regulation, and overall internal defense.  Essentially, when functioning properly, the gut helps us to get rid of what we don’t want and keep what we do. 

Furthermore, research on the human gut microbiome, the bacteria residing in the gastrointestinal tract, has led to critical findings on human health and diseases, including the impact on immune health

Gut bacteria and health outcomes are intricately linked.  In a nutshell, if you fail to nurture the health of the gut, you will also be setting yourself up for poorer immune health. 

Poor food choices and chronic exposure to chemicals and pollutants will burden the gut and contribute to dysfunction in the body.  These factors may also lead to a “leaky gut” where the composition of the gut lining becomes compromised and allow parts of food to escape.  Imbalanced nutrition can also compromise the immune system and leave it more vulnerable to infections.

Intestinal permeability (aka leaky gut) can lead to impaired nutrient absorption and may trigger food sensitivities.  Also, particles that pass through the gut lining will rev up your body’s immune response in an unintended fashion.  When this happens, a range of health problems may result.

Lifestyles that are sedentary or imbalanced may lead to further disruption of a healthy microbiome.  Microbiome disruption contributes to an imbalance within the composition of gut microbiota.  This may lead to a weaker immune system.  This cascade, so to speak, can set you up for the higher likelihood of infections and the manifestation of chronic health conditions.

Essentially, cultivating an environment where your gut and body can effectively operate, then rest and restore itself is the aim.  This can be supported through a consistent, daily focus on enhancing good gut health.

The same measures you would take to reduce oxidative stress and inflammation in the body will help to improve gut health.  A few other things to help boost the health of your gut microbiome include the following:

  • determining if you have any food sensitivities
  • increasing intake of pre- and probiotic foods
  • reducing sugar in your diet
  • increasing fiber intake
  • reducing chemical exposures from products in your day-to-day (skincare, food storage, etc.)

Sleep, Sleep, and More Sleep for Better Health

Sleep deprivation is commonly underlooked.  When life gets busy or hectic, it’s often the first thing that people slough off.  However, based on what we know from sleep science, there is no reason to make such excuses.  Doing so will only short-change yourself and could have significant implications on the health of your immune system.

Sleep is the time within our circadian rhythms that our bodies restore themselves.  Adequate sleep is critical to immune functionality, hormone regulation, and healthy digestion.  (Notice a theme?)

Sleep and immune system health are also intricately linked.  Lack of sleep may lead to the suppression of the immune system and weaken its ability to function. It can also lead to higher inflammation and greater susceptibility to infections.  If sleep deprivation continues over prolonged periods, the body’s defense system will get confused.  This dysregulation may contribute to the onset of chronic health conditions and diseases.

The importance of sleep should not be overlooked.  Good health and sleep habits often go hand in hand.

No one is saying to set up a bear cave for prolonged sleep.  Generally speaking, experts suggest 7-9 hours consistently across your days with the encouragement to keep bed and rise times the same.  People with chronic health conditions, such as autoimmune diseases, may find that 8-10 hours is more conducive for their health and wellness.

Sleep experts support establishing a sleep schedule and supplementation when needed.  Also, reducing the use of technology at least an hour (or more) before your bedtime may prove relevant.  This is due to the blue-toned lighting used in technological devices and the mental stimulation that engaging in certain digital activities may provide.  Finally, keeping social stressors in check may also lead to a better, more effective wind-down process before bedtimes.

The Meaningful Impact of A Healthy Relationship with Stress

Psychological and emotional stress, like oxidative stress, is much about finding a balance.  Some stress in our lives can help challenge us both mentally and physiologically.  However, persistent and enduring stress is what should present some concern.  Long-term mental or emotional stress may result from aspects within our lifestyle or as a result of a traumatic event.

The effects of stress on the immune system have been studied for some time.  Although acute psychological stress, (meaning circumstantial events that challenge us mentally), may provide boosts to the immune system and body’s overall resilience, chronically stressful lifestyles can cause trouble.

Over firing of stress hormones can reduce the effectiveness of the immune system.  Furthermore, researchers believe that chronic stressors may dysregulate the immune system.  This type of stress may contribute to weaker immune systems and a greater likelihood of developing illnesses.  Also, as we age, this risk may become higher.

As one expert describes it, the chronic, less-predictable stress is what throws our bodies out of balance.

Stress hormones and hormone-producing glands naturally spring into action when stress is experienced.  To the body, stressors are like threats to our livelihood that require an immediate response.  It is a natural way for the body to defend itself from what it perceives as threats.  However, this mechanism can also down-regulate some immune functions.  (It’s a little like putting them in reserves so the body can respond to the threat).

With short-term bursts of the body’s natural stress response, a healthy body will rebound.  However, if hormone levels like cortisol stay elevated for prolonged periods then, negative effects within the body will begin to initiate.  This cascade could set the stage for longer-term health consequences.

There are also compelling connections between sleep quality and the effects of psychological and emotional stress.  It’s nearly impossible to discuss one area without address the other.  The dynamic between stress and sleep is codependent.  In a nutshell, sleep deprivation may impair the regulation of stress hormones.  While the dysregulation of hormones that stress can trigger may impair sleep.  Needless to say, it’s an unproductive cycle.

Other stress-related effects on the immune system include increased inflammation, poor wound healing, a change in how the body responds to infectious agents, and impairments to digestion and, including the microbiome.  (Wow, can you see how all these factors are interrelated?!?)

Keeping stressors at bay through stress management, relaxation, and other techniques to calm the body should promote a healthier immune system.  A few options include the following:

  • Meditation and Deep-breathing exercises
  • Mindfulness therapies and/or Mind-body approaches
  • Daily movement, Coordinated exercise, and Yoga
  • Hormonal regulation therapies or supplements
  • Calming techniques such as EFT (tapping)
  • Remaining connected socially (with positive social connections)
  • Having a little fun or Laughter
  • Spending time in nature
  • Snuggling or playing with pets

Final Tips to Boost Immune Health

The areas detailed above are entangled.  Other things we know about keeping the immune system healthy include the following:

Immune system health has a lot of components.

It can be best to take a realistic and measurable approach.  First, do what you can to avoid unnecessary havoc on the immune system (i.e. clean up the junk).

Identifying a few realistic “start small” areas to gradually integrate into your daily life can be an effective strategy.  While other people may find the most success in identifying their most critical area of need and, then, starting to make changes related to it before moving on to other priorities.

Reducing burden or overload on the body while simultaneously boosting its processes and systems will help to support your body for overall health and well-being.

In terms of immune health, this can contribute to the lower risk of infection or improve the body’s ability to better manage infections that occur.  There are no guarantees, but factoring in the facets above and staying on track can increase the likelihood of favorable outcomes.

The good news is that much of the lifestyle measures and behaviors most supportive of good immune health have benefits that extend well beyond the health of the immune system.

What Are Superfoods and How Can They Help You

You may be hearing about “new superfoods” this year.

What does this mean and how can you fit this information into a realistic plan for health and wellness?  (Hint, see below for 3 tried and true tips).

Essentially the term “superfood” is not necessarily one that is scientific but may still be relevant to consider with identifying food sources that are packed with nutrients.

“Superfood” is indicative of a food source and the compounds within it that have been linked to certain health benefits or the prevention of adverse health conditions.  Many of these foods are derived from plant-based sources, although not all.

You will likely hear about the power of these foods concerning a range of health topics including, but not limited to the following:

  • weight loss
  • reversing or preventing cognitive impairments and our overall brain health
  • help in mental and emotional wellness, such as conditions like depression
  • overall health of the gut
  • stress reduction

The health benefits from these foods may include reducing excess inflammation and adverse oxidative stress which are two key factors involved in the discussion of chronic health conditions.  This is also a key reason for the emphasis on these “superfoods” when it comes to your health outcomes.

It seems that each year there is a new list of hot topic food options that can apply to your health and wellness but may also be trendy and, therefore, will show up in restaurants or product offerings.  This is not necessarily a bad thing, but something to be aware of as an empowered health consumer.

So, what are a few of these “2020 superfoods” that you may be hearing more about this year?

In somewhat of a continuation from recent years past, you will be hearing and learning more about fermented foods, seaweeds and algae, and seeds that are both edible and carry significant nutritional benefits.  Furthermore, food sources that may aid in your digestive health such as those with prebiotics, fiber, or digestive bitters.

A term that you may hear and could be new to you is “nervines” which are adaptogenic herbs supportive of your nervous system or are “neuroprotective”.  Nervines can also influence hormone regulation so can be important in many health-related conditions.  Also, these food sources may be good to include in your health plan for approaches to stress.

One of my all-time favorite companies for herbs, spices, teas, and essential oils is Mountain Rose Herbs.  They break down Understanding Nervines and Adaptogens in their blog.  Furthermore, Healthline, a leading source for consumer information related to health and wellness, also provides an overview of Adaptogenic Herbs.

Then, of course, there are the tried and true options such as berries, avocados, beets, dark leafy greens and microgreens, mushrooms, and fatty fish like salmon or sardines.  An important attribute to many of these foods is the rich pigments (i.e. color) of the food.  In natural foods, color is often indicative of nutrients critical to human health.

So how can you make sense of the term “superfood” used in media and marketing?

According to the leading global consulting firm, Accenture, consumers are changing to be more health-conscious and aware.  Also, the emphasis on personalized approaches to diet and nutrition is growing.

As a health and wellness professional myself, it is an exciting trend to observe.  Yet, it is also one to monitor for quality and overall relevance of the information.  As alluded to above, there is an intersect of science and marketing with the term “superfood”.  However, there are certainly ways to remain clued in and empowered as a health consumer.

In closing, 3 simple, tried and true approaches to include superfoods in your health and wellness are:

  • Eat colorful foods in variety
  • Incorporate nutrient-dense foods into snacking
  • Include herbs and spices in food preparation and cooking

If you simply start with and focus on these 3 tactics, you will undoubtedly be at an advantage when it comes to living most healthful and well.
