Immunity - the immune system and resistance
The immune system is our natural defense mechanism against external influences (pathogens) such as viruses, bacteria and other harmful substances. The strength and effectiveness of this system is often referred to as our 'resistance'. But what exactly is the difference between the immune system and resistance? And most importantly, can we strengthen our immune system to improve our resistance?
Difference between resistance and the immune system
Although the terms 'resistance' and 'immune system' are often used interchangeably, they refer to different aspects of our health. The immune system is a complex network of cells and organs that work together to protect the body against bacteria and viruses. Resistance is the ability with which our immune system can combat these influences. Strong resistance means that the immune system functions well and can respond quickly and effectively. Factors such as diet, sleep, stress and exercise can all influence resistance and therefore the overall health of the immune system.
How does the immune system work?
The immune system protects our body against external influences such as viruses and bacteria through an impressive process of recognition and response. But what exactly does the functioning of the immune system entail? First, the immune system recognizes invaders by unique characteristics, called antigens. It then responds by deploying immune cells such as macrophages, T cells and B cells. Macrophages 'eat' the invaders, while T cells attack infected cells and B cells produce antibodies that help neutralize the foreign invaders. After the threat has been averted, the immune system remembers the invader, allowing it to respond faster and stronger in the next encounter. This ingenious system not only keeps us healthy now, but also continues to protect us in the future.
Innate and acquired immune system
Our immune system consists of two parts: innate and acquired immunity. Your innate immune system is the part you receive at birth. It provides a general defense against pathogens. Acquired immunity, on the other hand, develops throughout our lives in response to exposure to certain external influences and specific defenses through vaccinations. This immunity provides a more specific and efficient response against certain foreign invaders that your body has previously encountered.
The role of the immune system and your defenses
Lower resistance can have various causes, such as stress, poor nutrition, insufficient sleep, or allergies. When you have low resistance, our immune system has difficulty effectively combating all foreign substances and they therefore have a greater chance of invading. It is crucial to understand how we can support our resistance to ensure that the immune system functions optimally so that your body can 'fight' against harmful external influences.
Vitamins for immunity support
An important way to support resistance is through healthy nutrition. Vitamin C is widely known as a powerful supporter of immunity. It not only helps immunity, but also plays a role in the function of white blood cells, which are a key component of a functioning immune system. Other important nutrients include vitamin D, vitamin E (as an antioxidant), zinc, and selenium. Each of these plays specific roles in the functioning of different aspects of both innate and acquired immunity.
By maintaining the right balance of these vitamins and minerals, and through other healthy lifestyle choices such as regular exercise and adequate sleep, we can give our immune system a significant helping hand and thus ensure good resistance.
The important role of mucous membranes in the immune system
Mucous membranes line many of the interior surfaces of our bodies, including the mouth, nose, throat, and digestive tract . These membranes form an essential (physical) barrier that helps to block harmful microorganisms and particles before they can penetrate deeper into the body. The correct functioning of the mucous membranes is therefore crucial for maintaining a healthy immune system.
Healthy mucous membranes depend on adequate hydration and specific nutrients, including vitamin A and zinc, which help maintain the structure and protective function of these mucus layers. Strengthening the mucous membranes can therefore help support general immunity and better protect the body against external attacks.
