Feeling Sick All the Time? Your Weak Immune System Could Be the Culprit
A healthy immune system is like your body’s silent guardian, always on duty but rarely noticed. It quietly patrols your skin, blood, and tissues, hunting down harmful bacteria, viruses, and toxins. It clears out debris, removes old or damaged cells, and even tackles potential cancer cells—all while managing inflammation to keep the healing process in check.
However, when your immune system isn’t up to the task, things can start to go wrong, leaving you with a weak immune system. You may become more vulnerable to infections, toxins build up, and aging or damaged cells linger. This can lead to bigger problems like cancer, autoimmune disorders (think lupus or rheumatoid arthritis), and chronic inflammation that won’t go away.

Understanding the Immune System
The immune system is our body’s internal self-defense mechanism against harmful invaders such as bacteria, viruses, fungi, and parasites. It begins with the outer physical barrier formed by the skin and mucous membranes in the mouth, nose, throat, and intestinal tract, which block the entry of pathogens. This first line of defense works constantly to keep invaders at bay.
Innate Immune System vs. Adaptive Immune System
If pathogens manage to breach these physical barriers, the innate immune system is the body’s immediate response team. Immune cells guarding the surfaces detect any invading pathogens or unwanted debris, such as toxins. When a threat is detected, the innate immune system:
- Isolates, engulfs, and destroys the invader.
- Removes debris to keep the body clean.
- In cases of injury or damage, whether internal or external, innate immune cells are alerted. They release chemicals to:
- Increase blood flow and promote inflammation at the injury site.
- Call in repair cells to begin tissue regeneration and healing.
If the innate immune system can’t fully eliminate an infection, the adaptive immune system is activated. This system is more specialized and learns to recognize pathogens over time. The adaptive immune system:
- Learns to recognize and remember every pathogen it encounters.
- Trains other specialized immune cells to identify the invader in the future.
- Coordinates attacks to destroy and eliminate pathogens anywhere in the body.
Whether the cells are part of the innate or adaptive immune system, they are always communicating with the brain and nervous system and coordinating their activity. If the immune system is healthy, strong, and balanced, it responds quickly and appropriately to the presence of invaders, toxins, or wounds and then returns to its baseline state of vigilance.
Signs and Symptoms of a Weak Immune System
A weakened immune system can reveal itself in several ways:
- Frequent Illness: You might catch every cold, flu, or respiratory infection you come into contact with. Additionally, infections may last longer than expected, indicating your body is slow to recover.
- Slow Wound Healing: If cuts, scrapes, or other injuries take longer to heal, this could be a sign your immune system isn’t able to quickly address damage and start the repair process.
- Digestive Issues: Symptoms like cramping, nausea, or loss of appetite may occur due to immune reactions to certain foods. Chronic inflammation in the digestive tract could also indicate ongoing immune problems.
- Chronic Inflammation: Ongoing inflammation in areas such as your intestinal tract, lungs, or joints might suggest that the immune system is struggling to resolve healing or remove infections effectively.
- Allergies and Asthma: Overactive immune responses like allergies or asthma drain the immune system’s resources. Constant allergic reactions, whether to dust, pollen, or food triggers, can leave the immune system weakened and exhausted.
- Fatigue: Persistent fatigue can be a result of chronic inflammation and immune responses. This constant state of alert and fighting off triggers or infections wears down the body, leaving you feeling tired all the time.
When symptoms of a weak immune system are always present and reveal a chronic vulnerability, it may be due to an underlying genetic or an acquired condition called immunodeficiency.
If immunodeficiency is suspected due to frequent infections, chronic inflammation, or slower than usual healing rates, then medical attention is warranted. This can be related to several conditions such as infections like HIV(AIDS), certain cancers that affect the bone marrow, medications like corticosteroids and chemotherapy, diabetes, and others have an inherited condition affecting their immune function.
What Weakens the Immune System?
Several factors can compromise the immune system’s ability to protect the body from infections and maintain overall health. Poor lifestyle habits, chronic stress and exposure to harmful substances can weaken the immune response, making the body more vulnerable to illness and inflammation.
Lifestyle Choices That Weaken Your Immune System
Lifestyle choices have a tremendous impact on the immune system and its ability to protect our body from invading microorganisms, eliminate old or mutated cells, direct wound healing, and remove toxins. There are several lifestyle factors that contribute to a weakened immune system.
- Nutritional Deficiencies: A lack of essential nutrients, vitamins, and co-factors affects the development and function of immune cells, making the body less able to defend itself.
- Processed Foods and Sugar: Diets high in processed foods, added sugars, alcohol, and artificial ingredients suppress the immune system and reduce the strength of immune responses.
- Exercise: Moderate exercise boosts cellular immunity, while prolonged or intense exercise without proper rest can inhibit immune function, leaving the body vulnerable to infections.
- Lack of Sleep: Poor sleep can cause the body’s energy reserves to be drained, making it harder to resist infections and increasing inflammation.
The impact of lifestyle choices is powerful, and the good news is that you are only one choice away from making a change.
Diets That Weaken Your Immune System
High-sugar and high-fat diets can severely weaken immune function by:
- Placing stress on the body, forcing all cells and systems to work harder.
- Can lead to chronic stress, which negatively impacts the immune system.
- Elevates insulin levels, resulting in increased inflammation.
High consumption of trans fats and omega-6 fats increases the inflammatory response.
While omega-6 fatty acids are essential, most industrialized nations consume them in excess compared to anti-inflammatory omega-3 fatty acids. The ideal ratio of omega-6 to omega-3 should be lower than 3:1; however, many Americans have ratios of 25:1 or higher, promoting a pro-inflammatory state in the immune system.
The Impact of Stress on the Immune System
Stress can have two opposite impacts on immune function. If the stress response is short-term, it can “rev up” the immune system to prepare an inflammatory and protective response in anticipation of a wound or infection that might occur during a fight or flight situation.
Long-term stress whether it be from emotional, physical, or chemical stressors will overwhelm the immune system and lead to a weakened immune response, chronic inflammation, and greater vulnerability to infections. Helping someone to address chronic stress patterns in their body is a vital step to improving immune health.
Exposure to Pollutants and Chemicals on the Immune System
While toxins, pollutants and chemicals are not pathogenic microbes, the immune system recognizes them as foreign and in need of removal. Naturally occurring molecules are easier for the body to eliminate. However, if the chemicals are manmade and unrecognizable by the immune system, then the immune cells will try to isolate them to prevent them from doing harm. If we are regularly exposed to chemicals that the immune system has to process, then this will contribute to the burden of the immune system causing it to fatigue. Additionally, this burden will promote chronic inflammation as the immune system is trying to eliminate the chemicals.

How to Strengthen the Immune System
A robust immune system will allow you to maintain overall health and well-being. It acts as the body’s defense against pathogens, helping to prevent infections and disease. Fortunately, there are several lifestyle strategies you can implement to bolster your immune function.
Lifestyle Habits to Boost Your Immune System
A healthy immune system relies heavily on regular physical activity, stress management, and sufficient recovery. By incorporating these key lifestyle habits, you can strengthen your body’s defenses. Moderate exercise is known to stimulate the immune response. High-intensity workouts, like HIIT (high-intensity interval training), can also be beneficial as long as the body is allowed to properly recover. Balance between exercise strain and recovery is crucial for benefits such as:
- Stimulating immune function
- Improving circulation
- Reducing inflammation
- Supporting stress management
- Boosting mood and energy
However, overtraining can lead to:
- Persistent fatigue
- Increased need for sleep
- Depressed mood or loss of motivation
- Higher susceptibility to colds or infections
- Stress and slow recovery
Managing Stress and Allowing Recovery
Stress is equivalent to strain and sleep is our body’s time to recover from that stress. Ideally, we experience an adequate amount of strain to challenge our body through activity each day to help us grow our resilience and adaptability. If this is balanced with enough quality sleep to recover from that stress, then the immune system will be stimulated and strong.
If stress exceeds recovery, then our immune system will progressively weaken and make us more susceptible to infections and the buildup of toxins, old cells, and mutated cells that need to be removed. If sleep exceeds stress as is ideal when one has an infection or is not feeling well, then healing will be favored allowing the immune system and the body to recover. To avoid a weak immune system, prioritize getting enough sleep to support recovery and resilience. It’s also essential to manage stress, so that you can sleep. If you’re finding it difficult to sleep due to stress, we’ve covered many helpful tips on how to sleep when stressed.
Hygiene and Microbial Exposure
Our world is teeming with microbes, many of which play an essential role in maintaining our health. Proper hygiene helps us manage exposure to harmful pathogens while allowing our microbiome to thrive.
The human body is home to trillions of microorganisms, forming our microbiome, which is vital for survival and health. Exposure to these microbes, especially in childhood, helps the immune system develop properly. Not all microbes are harmful; our immune system has co-evolved with them over millennia and can effectively manage them if it’s strong and balanced.
Basic hygiene, like hand washing and maintaining personal cleanliness helps reduce exposure to potentially harmful microbes, such as those found in:
- Rotting food or garbage
- Feces
- Coughs and sneezes
Excessive use of toxic chemicals or alcohol-based sanitizers can lead to resistance in certain superbugs, making them harder to eliminate. Pathogenic microbes pose a greater risk when the immune system is weak. However, maintaining strong immunity through better self-care and lifestyle choices can protect you, even in microbial environments where others may get sick. A strong immune system is more important than simply avoiding germs. Since exposure is inevitable, a balanced immune response allows us to adapt to the microbial world around us.
Food Choices for a Strong Immune System
Eating a nutritious, paleo-style diet will provide the immune system the resources it needs to function properly. A paleo diet is one mimicking that consumed by our hunter gatherer ancestors from 40,000 years ago with whom we share 99.98% of our genes. This means that we are genetically programmed to handle this type of diet. It includes:
- Plant-Based Foods: Emphasizes fruits and vegetables, locally and organically harvested, in season—aim for a rainbow of colors, as different colors contain various vitamins and minerals.
- Lean Proteins: Incorporates pasture-raised lean meats, wild caught fish, pasture-raised eggs, nuts, and seeds.
- Hydration: Our bodies are mostly composed of water, so it’s essential to stay properly hydrated. Aim to drink half your body weight in ounces each day, increasing this amount on hot days or when working out. Adequate hydration facilitates communication between immune cells and helps maintain their circulation throughout the body.
Natural Immune Boosters
Certain foods are particularly beneficial for the immune system due to their higher levels of specific vitamins and compounds. Consider including the following in your diet:
- Vitamin C: Citrus fruits, mushrooms, and bell peppers.
- Vitamin D and A: Cod liver oil (Vitamin D); carrots, sweet potatoes, and squash (Vitamin A).
- Vitamin E: Found in nuts and seeds, with Brazil nuts being high in selenium.
- Zinc: Shellfish and legumes are excellent sources.
- Omega-3 Fatty Acids: Found in wild-caught, cold-water fish, as well as pasture-raised eggs, meat, and poultry.
Do you suffer from any of these symptoms and are looking for relief?
Gut Health and Immunity
Maintaining gut health significantly impacts the immune system, as nearly 70% of our immune system is located in the gut. The gut microbiome ideally consists of a well-established and balanced ecosystem of bacteria, viruses, and other microorganisms. This microbial ecosystem is essential for immune health because it:
- Supports Gut Barrier Function: Helps maintain the cells of the gut barrier, preventing toxins and pathogens from entering the bloodstream.
- Aids Digestion: Facilitates the breakdown of food and the absorption of nutrients.
- Synthesis of Vitamins: Contributes to the production of essential vitamins.
- Eliminates Unwanted Substances: Assists in the removal of harmful compounds from the body.
The gut microbiome also communicates with immune cells and the brain, which helps to modulate immune system activity and regulate immune homeostasis. This communication plays a vital role in how the immune system responds to foods and microbes encountered in the gut.
Chronic inflammation in the gut or elsewhere in the body can lead to a condition known as “leaky gut.” This occurs when the linings of our mucous membranes become compromised, allowing larger-than-normal food particles, toxins, and even unwanted bacteria to enter the bloodstream.
To maintain a healthy digestive system and a robust gut microbiome, it is crucial to nurture our gut lining and tighten the gaps between gut cells. This approach can help reduce the risk of leaky gut and its associated health problems.
Supplements and Herbs for the Immune System
While nutritional supplements may seem completely safe, there are many reasons why you should consult with a healthcare professional before starting to take them. Depending on your physiology, deficiencies, and/or health challenges, your body may not need a given vitamin or mineral, and you may not respond to a given supplement as expected or as advertised. Take a holistic approach and have a healthcare professional create a proper health development plan to provide your body with nutrient sufficiency, before starting any supplementation for a weak immune system.
Herbs & Key Nutrients for Immune Health
To maintain a healthy immune system, it is essential to provide it with sufficient levels of crucial nutrients. Adequate protein intake is vital for repairing tissues and producing antibodies. Key nutrients to consider include:
- Vitamin D: Necessary for balancing immune activity; deficiencies are associated with an increased risk of respiratory infections and autoimmunity.
- Vitamin C: Helps immune cells reach infection sites and eliminate pathogens effectively.
- Zinc: Essential for the thymus gland’s production of infection-fighting T cells.
Probiotic supplements and probiotic-rich foods, such as kombucha, sauerkraut, kimchi, and yogurt, play a significant role in supporting the immune system. These foods help to restore healthy bacterial strains in the gut microbiome, which is vital for overall immune health. Probiotics not only repopulate beneficial gut bacteria but also stimulate immune cells and enhance various immune functions.
Many herbs are also helpful for their natural immune supporting benefits. Herbs like echinacea, elderberry, chamomile, and andrographis have anti-viral properties amongst other properties that support immune health and can help the body fight colds and the flu. Oregano has all-around anti-microbial properties as well as being antioxidant, and anti-inflammatory.
Holistic Approaches to Immune Support
Promoting strong overall health, particularly immune health, requires a holistic and integrative approach. While the physical, mental, and spiritual aspects of life can be studied separately, they are interconnected and function as one. Mental health significantly influences physical health, and research indicates that interventions targeting mental and spiritual well-being can lead to improved immune function.
- Psychosocial and Psychotherapy Interventions: Studies show that these approaches enhance the immune response.
- Stress Reduction: Efforts to improve mental and spiritual health can help balance and improve immune function.
Deepak Chopra eloquently stated, “Every cell in your body is eavesdropping on your thoughts.” This underscores the importance of being mindful of your beliefs, expectations, and focus. Where you direct your thoughts, and energy can profoundly impact your immune function and overall health outcomes.
There are many holistic practices that have been found to improve immune health. A common feature of these approaches is that they help to reduce stress in the body. Another is that they promote a sense of calm. Chiropractic and acupuncture have been shown to increase a sense of relaxation, lower stress and inflammation, and increase white blood cell levels.
Massage therapy has been found to support immune health by helping with lowering stress, detoxification, circulation, improving sleep, and increasing white blood cell activity. Other holistic therapies that are helpful at reducing stress include reiki, qi gong, and biofeedback.
When to Seek Professional Help
While common ailments such as colds, fevers, rashes, and food reactions may come and go without the need for medical intervention, it’s crucial to keep your healthcare professional informed about any changes in your health. Regular communication allows them to provide the best guidance tailored to your situation. If infections, inflammatory responses, or immune reactions do not resolve as expected, seek medical attention.
Many people and some preliminary studies have reported that chiropractic care has helped improve immune health, but large scientific studies have yet to be done to prove the connection. There is a solid biological plausibility that these known benefits of chiropractic care such as: correcting spinal misalignments and reducing stress on the spinal cord, lowering stress dominance patterns in the nervous system, and restoring healthier brain-body communication can all contribute to a healthier immune system.
At Whole Body Health Chiropractic, we have witnessed numerous patients experience better immune function, such as:
- Improved nasal breathing with reduced congestion
- Alleviation of asthma and allergy symptoms
- Decreased frequency of seasonal respiratory infections
- Faster recovery times from colds and infections
While these are anecdotal reports, they are so commonplace across experiences in chiropractic offices that they warrant more research in the future.
Chiropractic adjustments can also indirectly help improve immune health by:
- Improving sleep
- Decreasing pain and inflammation
- Increasing a sense of wellbeing and lowered stress
- Decreasing cortisol levels and the fight or flight response
- Improving blood flow to the brain
