The immune system is a specialized group of cells, tissues, and organs that work together to protect against incoming invaders. Take precautions to fortify your immunity if you have any of the symptoms below:

How Strong Is Your Immune System / Red Flags


The immune system is a specialized group of cells, tissues, and organs that work together to protect against incoming invaders. Take precautions to fortify your immunity if you have any of the symptoms below:

1. You Catch Every Cold And Flu That Goes Around


Your immune system is struggling if you’re constantly sick. Or if you’re sick longer than a week – that’s about how long it takes a common virus to run its course. A healthy immune system’s function is to stop bacteria and viruses in their tracks before they take hold and cause an infection.

It’s normal to get a couple of infections a year, any more than that is an indication that your immune system needs some tender loving care. People with inhibited immune function are more apt to come down with secondary infections, such as pneumonia, bronchitis, sinusitis, ear infections and skin infections.

2. You’re Constantly Tired


It’s normal to feel tired after a long day. However, if you’re always dragging and fatigued, even after a full night’s rest, your immune system may not be up to snuff. Your body is sending an alert that it’s trying to converse energy in order to boost immune function. Hence, the constant exhaustion. Immune function and energy levels are directly correlated.

Oxygen and nutrients depend on good circulation to be delivered to the cells, tissues, and organs of the body. When this doesn’t happen, you’ll feel tired and sluggish. Energy production is dependent on both oxygen and nutrient-delivery.

3. Your Digestion Is Less Than Optimal


Bowel problems, such as diarrhea and constipation can be indicators of depressed immune function.  Gut bacteria, within the gastrointestinal tract, closely corresponds with healthy digestion and immune function. In fact, the immune system is in constant interaction with the microbiome to keep the body in homeostasis, or balance.

A significant portion of the immune system resides in the gut, with bacteria in the intestines secreting huge quantities of protective antibodies. Unbalanced bacterial flora can shift immune function into an inflammatory state, resulting in intestinal permeability, or leaky gut.

4. Poor Circulation


Are your extremities, including your hands and feet, always cold? Poor circulation impacts blood flow, and can lead to reduced immune function because the cells and tissues of the body are not receiving adequate nourishment. Amino acids and minerals, which are carried in the blood, are necessary for the immune system to function as it should.

Faulty circulation impedes nutrients from getting to where they’re needed for repair and healing. An optimally functioning circulatory system is also imperative for proper brain function, memory recall, and concentration. The brain suffers when blow flow is impeded.

5. You Have An Autoimmune Disease


Autoimmune diseases are on the rise, with millions of people having some form of autoimmunity. Autoimmunity occurs when the immune system mistakenly targets the body’s own tissue as foreign, mounting an attack on it, which damages tissue. In such cases, the immune system can be either inhibited or overactive.

Hashimoto’s thyroiditis, multiple sclerosis, lupus, rheumatoid arthritis, Celiac disease, Guillain-Barre syndrome, Addison’s disease, Grave’s disease, type 1 diabetes, scleroderma, and psoriasis are all diseases where the immune system attacks healthy tissue that it’s targeted as non-self.

There are over 80 diseases that are autoimmune in nature. It’s not uncommon for a person to have more than one autoimmune disease – for instance, Hashimoto’s and Celiac disease are often seen together. Autoimmunity reduces immune function, increasing the likelihood that infections can take hold. Autoimmune diseases are also associated with inflammation, which depresses immunity.

6. You’re Always Stressed


Have you ever noticed that stress makes you more susceptible to infections? This is because being stressed (particularly chronic stress) reduces the number and function of lymphocytes, white blood cells found in the bloodstream and lymphatic system.

When you’re stressed, you’re also anxious. Both stress and anxiety impact immune function via the sympathetic branch of the autonomic nervous system. The sympathetic branch is the flight or flight system that is activated during times of acute stress.

When stress becomes chronic, however, and the system is activated for long periods of time, hormonal changes can lower the body’s resistance to infection. For instance, high cortisol levels weaken the immune system by reducing white blood cell count and increasing inflammation.

Chronic stress also fosters the development and growth of tumors. It doesn’t help matters that in times of stress, people often resort to unhealthy coping mechanisms, such as eating poorly, not exercising, not getting enough sleep, and drinking alcohol, all of which inhibit immunity.

7. Poor Wound Healing


The immune system plays a vital role in orchestrating the repair, regeneration, and healing of tissue.

Inflammation, which reduces immune function, is implicated in abnormal wound-healing, whereas, a reduction in inflammation accelerates healing, while decreasing scarring.

Impairments in immune function, coupled with excessive immune reactions impede wound-healing.

Macrophages, immune molecules, are responsible for regulating and mediating the proliferate phase of the immune system, which is involved in healing.

This is in opposition to the inflammatory phase, which does the opposite. Changes in macrophage activity, specifically the switch from M1 macrophages to M2, correlate with reduced wound-healing.

8. Shortness Of Breath


Anemia, that is autoimmune in nature, can be the result of malfunctions in the immune system that produce auto-antibodies. These antibodies can then attack red blood cells, which carry life-giving oxygen throughout the body. When this process is impaired, it can lead to fatigue, shortness of breath, abdominal pain, and jaundice.

9. Rashes


Our skin is the first line defense against foreign microorganisms. Abnormal symptoms that involve the skin may be an indication that immune function is compromised. Rashes, inflammatory skin disorders, and allergic reactions can all be the result of the immune system overreacting. Itching, red, scaly skin is a symptom of inflammation, a sign that the immune system is struggling.

Food sensitivities, reactions to medications, along with hypersensitivity reactions, can all cause rashes brought on by immune-system dysregulation. Autoimmune diseases involving the skin, including scleroderma, lupus, dermatomyositis, and vasculitis can also cause inflammatory skin rashes.

10. Lack Of Nutrition


Malnutrition, caused by poor nutrient-assimilation, depresses immune function, promotes inflammation, increasing the likelihood that infections. can take hold. Immune defects are seen in both over-nutrition and under-nutrition. Many times poorly-nourished children die of common infections that a healthy immune system would otherwise fight off.

Healthy intestinal function is dependent on a steady supply of nutrients. The structure and function of the gut are altered when this doesn’t happen. Inadequate nutrition also directly affects monocytes and memory T-cell function. Poor immunity, in turn, leads to malabsorption, decreased growth hormone production, and HPA-axis dysregulation, along with an increase in metabolic demand.

Ways To Boost Immune Function


There are things you can do on a daily basis to optimize the function of your immune system:

  • Eat right for your metabolic type. The right mix of macronutrients (protein, fat, and carbohydrate), and micronutrients (vitamins and minerals) will keep your immune system balanced. It will also optimize the production of ATP, which corresponds to healthy energy levels.
  • Exercise: Movement is necessary for detoxification, good circulation, and proper immune function, however, don’t over do it. Overexercising can dysregulate hormones and endocrine function. More is not better, in this regard.
  • Get enough sleep: Rest when you feel like it. It’s not a crime to take a nap when you’re tired. Listen to the signals your body sends.
  • Say “No” to things you don’t want to do to. Doing things that don’t resonate with your vision, your schedule, or your energy levels is a surefire way to compound your stress.
  • Keep sugar to a minimum: It depresses immune function, and is hard on blood sugar and insulin levels. It’s also inflammatory.
  • Practice self-care consistently: Do things that nourish your body, soul, and spirituality. Never underestimate the power of downtime.
  • Surround yourself with people who support you and validate your feelings. Isolation and loneliness diminish immunity, whereas community, communication, laughter, and friendship fortify immune function.
  • Support your liver: Good liver function is essential for maintaining a healthy weight, for balancing the endocrine system, and for strong immunity. And that’s just for starters. Healthy liver function is absolutely paramount for good immune function. Implementing detoxification strategies on a consistent basis is a foundational pillar of health that often gets neglected.
  • Keep your weight within a healthy range : Excess body fat is inflammatory, which negatively impacts immune function.
  • Don’t smoke: This goes without saying. Also, keep alcohol to a minimum. It imbalances blood sugar and wreaks havoc on the liver.
  • Supplementation: Flood your body with nutrients that build it up and replenish what’s missing. Liposomal vitamin C, vitamin D, ozone, hydrogen water, and magnesium are a few of my favorites. Red light therapy is amazing for reducing inflammation and pain.
  • Find ways to deal with stress: Stress affects the automatic nervous system, which in turn, directly affects immune function.
  • Practice good hygiene: Wash your hands throughout the day, cover your mouth while coughing or sneezing, stay home when you’re sick, and disinfect household surfaces regularly.

  1. This is such an interesting topic and one that is rarely covered. The focus is usually on foods that promote good immune function, but I have always wondered how strong or how effective is it really or how can I detect that my immune system is struggling.

    This year has been good to me so far because I have yet to catch the flu or a cold. I usually get an infection once a year or so or sometimes not at all. 

    How stress correlates to immunity is interesting. I would never associate stress with depressing my immune system. It makes sense though, and it’s true that people try to ease their stress with destructive habits like drinking or sleeping too much. Or not getting enough sleep. It can lead to an ugly and toxic cycle. 

    Thanks for sharing this wonderful information!

    • Hello,

      Thanks for reading my article on immune function. It’s such an important topic in light of the pandemic. Covid-19 aside, diseases like cancer, autoimmunity, cardiovascular disease, and diabetes are on the rise. Sadly in fact, they are epidemic. 

      Since the immune system is our number one defense against infections, it’s worth knowing the signs that signal it is struggling. Many people don’t associate symptoms, like rashes, with poor immunity. 

      Once you know your immune capacity is compromised, however, you can take steps to remedy the problem. And there are many lifestyle strategies, when implemented consistently, make a significant difference. 

      Thank you for taking the time to comment:)

    • Hi Jackie,

      Thanks for reading my post and for taking the time to comment. The immune system is so vital in keeping us healthy. It’s important to be alerted to the signs of reduced immunity so you can implement strategies before you get hit with something hard. 

      This is particularly important during the pandemic that has been going on for months now. Many of the symptoms that I’ve talked about may not be immediately correlated with poor immunity. Getting sick all the time certainly is, but shortness of breath and rashes? It’s such an interesting topic. I’m glad you learned something:)
