Our Immune System

In December, the colds accumulate. We stay indoors are often tired and listless and the immune system has to adjust to the cold winter months. Therefore we created the December Challenge to help you strengthen your immune system and stay healthy through the winter.


Organs of the immune system


Among the organs of the immune system are the blood and the so called lymphatic system with the lymphatic organs. In addition the skin and mucous membranes provide important protection against substances and external intruders.


Skin and mucous membranes

Throughout the body, the skin and mucous membranes are the first important barriers against bacteria, viruses and fungi, for example. They are like a mechanical barrier that shields the body from the outside world.


There are also other defense mechanisms that support the immune system:   


Bacteria-inhibiting substances (e.g. enzymes in saliva, urine or tear fluid) stop foreign intruders.    Mucus in the respiratory tract ensures that inhaled pollutants initially stick and are transported outwards again by the movement of the cilia.    Stomach acid destroys most pathogens that enter the body through food.    Useful microorganisms colonize the skin and many mucous membranes (e.g. microbiome of the intestinal flora) and fend off pathogens.    Reflexes (coughing, sneezing) also protect against pathogens. 


Primary lymphatic organs


The lymphatic system consists of the lymph vessels and the primary and secondary lymphatic organs. The primary lymphatic organs form certain defense cells, the lymphocytes. These organs include:   

  • Bone marrow: central organ of the immune system inside the bones, where blood cells are formed and for the most part also mature - with the exception of immature

  • T-lymphocytes   

  • Thymus gland: organ above the pericardium in which the T precursor cells mature


Secondary lymphatic organs


In contrast to the primary lymphatic organs, an actual immune defense takes place in the secondary ones. The mature defence cells migrate from their place of formation to where they then develop further depending on the pathogen and pollutant and fend off the intruders. These organs of the immune system include   

Spleen: Foreign substances (antigens) enter the organ in the left upper abdomen via the blood   

  • lymph nodes: Usually antigens get there via the lymph from the lymph vessels 

  • Mucosa-associated lymphatic tissue (MALT): The surface of the tissue establishes contact between foreign substances and defence cells, which then take up the fight. 

  • Tonsils (tonsils, NALT = Nasal-Pharyngeal-Associated Lymphoid Tissue) e.g. palatal or pharyngeal tonsils 

  • Lymph tissue in the intestine (GALT = Well-Associated Lymphoid Tissue), like appendix and the Peyer's Plaques in the small intestine   

  • Immune tissue in the airways (BALT = Bronchus-Associated Lymphoid Tissue)     

  • Lymphatic tissue in the urinary



How to strengthen our immune system


Start your routine right after getting up. Squeeze a fresh lemon, preferably from organic farming. Drink the shot in one go. If you find it too sour, dilute the lemon with water. Lemons contain a lot of vitamin C (up to 50 mg vitamin C per 100 grams of lemon) and are therefore a great support for your immune system.  But not only that, vitamin C also improves the absorption of iron in the body, which is also important for a strong immune system. Since our body cannot produce the vitamin itself, it is essential that we absorb it with food. In addition, regular drinking of lemon water can not only prevent colds - even if you already have a cold, lemon juice helps to fight bacteria in your throat through its antibacterial effect and helps you get well faster. The body can process the vitamins better on an empty stomach so it is important to drink the shot before you eat anything else.


In order to develop a routine more easily, it is recommended to start with the meditation immediately afterwards.

Sit in a comfortable seat of your choice and straighten your spine.

Put your thumb and index finger together in Chin Mudra for better concentration.

Your hands rest on your knees. Take a few deep breaths in and out to find yourself and release from your thoughts.

Place your hands on the floor next to your pelvis and imagine there are bright glittering rays of light coming out of it. Slowly move your arms across the side up to your head until they touch and back to the floor.

Repeat the movement fluently. Breathe deeply and relaxed.

Imagine how you draw the rays of light around your body through the movement of your arms. Slowly the circle of light around you becomes stronger and stronger. It surrounds you completely.

This circle of light protects you from everything outside. Nothing comes through it that you do not want to let through. Only what you want to let out of the circle can leave it. When the circle of light feels strong enough, put your hands back in Chin Mudra on your knees. Feel the circle of light around you as it protects you.

Take it with you into your day, it is your constant companion.


Fresh air is essential for a completely strong immune system. Try to set a fixed time each day when you walk outside for at least 5 minutes. Breathe consciously and fill your lungs with fresh oxygen. A short walk through the woods or across the meadow will increase your lung capacity and lower your blood pressure and the risk of arteriosclerosis. Japanese researchers could even prove that the forest walk activates natural, endogenous killer cells that eat cancer cells. The increased cell activity even continues for up to a week after the walk. That way you stay fit and healthy during the winter.
