The role of the thymus
The importance of the spleen
Lifestyle factors that influence your immune function
The primary mission of the immune system is to shield us from harmful invaders. Remarkably, it keeps a detailed record of every microbe it has ever defeated, enabling it to recognize and eliminate these threats swiftly if they attempt to invade again.
Starting today, we will delve into the fascinating processes that make the immune system so effective. We will also share practical tips on how to support and enhance the function of different components of your immune system.
Protective barriers in immunity
Defending your body
Are you ready to embark on an in-depth journey into your immune system? Let’s get started—today, we’re discussing the organs that function as barriers.
The innate immune response serves as our first line of defense against harmful invaders such as bacteria and viruses. This initial defense comprises several crucial components:
Antibacterial substances and enzymes: Found in saliva and the airways, these substances can kill germs as they enter the body.
Mucus in the lungs: This sticky substance traps germs we inhale, allowing them to be removed from the airways by hair-like structures called cilia.
Stomach acid: This potent acid neutralizes germs that enter the body through food, preventing them from progressing further into our system.
Beneficial bacteria: These harmless bacteria reside on our skin and in mucous membranes, where they attack and outcompete harmful germs.
These barriers play a vital role in our immunity. As the first line of defense, the innate immune response acts swiftly to identify, attack, and destroy invading pathogens.
One simple yet effective way to assist our immune system is by frequently washing our hands. Germs from unwashed hands can enter the body through food or by touching our eyes, nose, and mouth. These germs can also be easily transferred to others. By maintaining good hand hygiene, we help remove harmful germs, preventing infections and supporting our immune system's efforts to keep us healthy.
How’s your lymphatic system?
Book that massage!
Another crucial system essential to our immunity is the lymphatic system, comprising primary and secondary lymphoid organs. The primary lymphoid organs, including the bone marrow and the thymus, create special immune system cells called lymphocytes. The secondary lymphoid organs, such as the lymph nodes, spleen, tonsils, and certain tissues in various mucous membrane layers, are where immune system cells do their job of fighting off germs and foreign substances.
Massage is a great way to help maintain the health of your lymphatic system. A specialized type of massage called lymphatic drainage can be performed by a trained massage therapist. Using a series of gliding, compressing, stretching, and cupping motions, these light rhythmic movements stimulate the lymphatic system, enabling the lymph to circulate through the lymph node system.
Lymph fluid is a mixture of water, proteins, immune system components, waste products, and other remnants of cell metabolism. Many people incorporate lymphatic drainage massage into their skincare and wellness routines due to its detoxification and aesthetic benefits. It provides relief from chronic pain, digestive problems, hormonal imbalances, skin conditions, allergies, headaches, and many other issues.
All about the thymus
Get some vitamin A
How much do you know about the thymus? This little-known organ plays a significant role in immunity. It is part of both the lymphatic and endocrine systems and is located behind the breastbone, above the heart.
Lymphocytes, also called T cells, mature in the thymus and perform many essential functions, including coordinating the processes of the innate and adaptive immune systems. The innate immune system, which we’ve discussed in previous messages, involves non-specific processes that attack all invaders. Its main purpose is to immediately prevent the spread and movement of foreign pathogens throughout the body.
In contrast, the adaptive immune system is more specific in its response to invading pathogens. Adaptive immunity develops as we age, reacting to the different germs we are exposed to. While the innate immune response is immediate, the adaptive immune response takes longer to activate but is long-lasting, highly specific, and sustained by memory T cells. Both types of immunity are vital in protecting us from illness.
Another important role of T cells is to constantly monitor the surfaces of all cells for changes as they move through the body, signaling the adaptive immune system to potential dangers.
Certain vitamins support the thymus gland and the immune response. Vitamin A, found in foods like carrots, sweet potatoes, and winter squash, supports the thymus gland and stimulates the immune response. Vitamin C, found in bell peppers, broccoli, and Brussels sprouts, helps maintain the size and weight of the thymus and increases the number of T cells produced. Dark leafy greens such as spinach, kale, and collard greens are excellent sources of both vitamins.
The spleen and immunity
Taking care of your spleen
On to the next organ, the spleen. This important immune organ is located in the left upper abdomen, beneath the diaphragm.
Some of its many roles include the storage of various immune system cells, the breakdown of red blood cells, and the storage and breakdown of platelets, which are responsible for blood clotting. The spleen is the largest secondary lymphoid organ and plays a significant role in filtering the blood, making it a major component of the immune system.
To eat for spleen health, incorporate the following foods into your diet:
veggie-abundant soups and broths;winter squash, carrots, rutabagas, parsnips, turnips, sweet potatoes, yams, and pumpkins; legumes like garbanzo beans, kidney beans, adzuki beans, lentils, black beans, and peas; sesame seeds, pumpkin seeds, and sunflower seeds; seaweed and kelp.
Spleen-healthy spices include ginger, pepper, cardamom, onions, garlic, cinnamon, clove, fennel, rosemary, sage, turmeric, thyme, horseradish, cayenne, and nutmeg.
Everyone’s got some
Feeling Stressed? Take a deep breath
How’s your stress level? Stress can have an adverse effect on our health in numerous ways. When we’re stressed, the immune system’s ability to fight off antigens is reduced, making us more susceptible to infections. The stress hormone corticosteroid reduces the number of lymphocytes, suppressing the effectiveness of the immune system. Additionally, common unhealthy coping behaviors brought on by stress, such as drinking and smoking, can have an indirect effect on the immune system.
It’s important to find ways to reduce stress throughout your day for your immune system to function optimally. A simple and fast-acting stress-relieving technique is intentional breathing, such as deep breathing. Deep breathing is our body’s built-in stress-relieving system and has been scientifically proven to affect the heart, brain, digestion, and immune system.
One simple deep breath immediately signals the brain to slow down and relax. As this message spreads throughout the body, a feeling of calmness takes over as muscle tension eases. Try setting daily reminders to practice deep breathing. Throughout the day, and especially when you’re feeling overwhelmed, frustrated, stressed, or anxious, remind yourself to take several slow deep breaths.

Check your habits
Get more sleep and exercise.
Sleep is a process that allows your body to regenerate. While we sleep, we’re strengthening our immune system. During sleep, our T cells increase, and inflammatory cells decrease. However, when we’re sleep-deprived, the opposite is true, resulting in decreased immunity.
Sleep quality and exercise go hand in hand. Exercise helps burn off excess energy, which can otherwise leave us feeling restless. Exercise also contributes to overall good health, including a healthy immune system. It promotes healthy blood circulation, necessary for removing toxins and delivering immune cells throughout the body. Regular exercise allows your immune system to move through your body freely and do its job efficiently.
Adults need 7-8 hours of sleep each night. If you have trouble getting to sleep, try creating a calming nighttime routine. Some people enjoy taking a warm bath or doing gentle stretching to signal the body that it’s time for rest. Avoid eating or drinking close to bedtime, as well as checking emails or other stress-inducing activities.
When it comes to physical activity, adults need at least 150 minutes per week of moderate-intensity aerobic activity or 75 minutes per week of vigorous aerobic activity, or a combination of both, preferably spread throughout the week. Strength training with weights or resistance bands is also recommended twice a week.
By prioritizing sleep and regular exercise, you can significantly boost your immune function and overall well-being.
Diet is key
Eat for health!
The foods you eat can significantly improve or hinder your immune system. Aim for a well-balanced diet that incorporates a variety of colorful fruits and vegetables every day. The more color you can incorporate into your diet, the better your chances are of getting a variety of nutrients. To complete your balanced diet, opt for lean proteins such as fish and chicken and complex carbohydrates like brown rice and quinoa.
Boosting Your Immune System with Gut Health
To improve the function of your immune system, it is also recommended to prioritize your gut health. This can be accomplished by eating probiotic foods, which are foods containing live microorganisms. Try incorporating the following fermented foods into your diet to increase your intake of natural probiotics: unpasteurized sauerkraut and kimchi, tofu, miso, natto, and kombucha.
