Bist du krank? Schnupfen, Fieber, Grippe: Was bei Erkältung im Körper passiert! [Arzt reagiert]

Yes, I'm a little out of breath and I have a great reaction to it today. I actually posted some colds and coughs and sneezes on YouTube myself and not only came across my own videos, but also this video here, which I'm watching now. I had already watched it today, I really liked it and now we'll take a look at it together. And now I'll supplement from a patient's point of view, but also from a doctor's point of view. Hello, my name is Dr. Tobias Walke and with my YouTube channel I would like to make a contribution to clarify medically understandable and correct about diseases, causes of these diseases. And because many have asked for it, I also go into other videos on the topic of health, medicine, diseases and explain the topics a bit from a medical, medical point of view. So if you don't want to miss anything anymore, feel free to subscribe to my channel now. There is this myth, what doesn't kill you makes you stronger. That you are better equipped when you have survived a disease. And somehow that also seems logical, because we have all experienced that. If we have to go through something difficult, we are often more resilient afterwards and can better master difficult situations. Right at the beginning here, a very important term that falls here, resilience. Resilience and with that, in principle, the adaptability is made. The adaptability of us humans, of our body to changes. This can be both mentally and psychologically. I'm sure you've heard it before. But our body also reacts to new situations through changes. Most of the time we don't even notice it. Non-resilient people are often referred to as vulnerable. But in fact, what doesn't kill you makes you weaker sometimes. What happens when you get sick? Yes, very good question. Exactly, the technical term here is open window. Maybe one or the other of you will remember that I have already spoken about it several times in connection with sport and disease. In sports immunology, they call it open window. After very exhausting, extreme sports sessions, we first have such an open window and are then more susceptible to colds. Our body is basically flatter. It is very much in demand. And that will be transmitted here now. Because our immune system is then basically in the basement for the first time. And just like in the first moment, even with a cold, or rather, it is not in the basement, but in high operation. But of course our whole body is extremely burdened, is challenged, and we'll see that right now. Imagine you were a large country with a considerable army to defend. You are surrounded by enemies who want your energy and resources for your country. Because it is about life or death, the body has developed in such a way that it reacts quite sensitively to damage and enemies. Because there could be an invasion at any time, and then the body has to react quickly. Let's start such an invasion and see what happens. As soon as your cells notice that something is wrong, they release a wave of signal proteins called cytokines. They are like alarm sirens that activate the most diverse immune cells, which release even more cytokines and also strengthen the alarm. Very soon, a lot of signals, precautions and countermeasures will be initiated. The mobilization has begun. So, before I go any further on this, very briefly on my own behalf, I would like to point out to my advisors, and especially to this new advisor here, the best foods, successful nutrition samples for muscle building, fitness and weight loss. I also have an advisor specifically on the topic of the immune system. Which micronutrients, which supplements are important for our immune system? So if that's what you're interested in, feel free to take a look at my shop. But now let's continue with the video here. So here we see what happens with a cold. Our immune system works like a well-oiled mechanism. And within a few hours, most of the pathogens can be identified and made harmless. And many, many structures are involved in this immune system. Titoquine was mentioned here once, and I'll show you a few more facts about it. Very important to know about the immune system. Five facts. First, there is a difference between an innate immune system and an acquired immune system. I'll get to that in a moment. Second, we can strengthen our immune system. Namely, through measures such as sports, a healthy diet, and also, let's call it, the right challenge. Keyword, resilience. So they challenge the immune system and make it stronger. But we can't strengthen our immune system through supplements and co. to 99%. Instead, supplements only contribute to a functioning immune system. That's a big difference. Third, as I said, there are many, many structures and cells involved in an immune response. Titoquine was mentioned here once, and I'll show you a few more facts about it. It is estimated that every tenth cell in our body is an immune cell that contributes to our protection. That's a lot. And fourth, you should also know that through the so-called immune memory, a body builds a database against all the harmful influences it has experienced so far. Last point, then we'll continue in a moment. Fifth, those who never rest are more likely to get sick. Chronic stress weakens the immune system. Your brain activates disease behavior and prioritizes defense. First, you notice that your energy is running low and you get tired. You feel sluggish, often worried or depressed, and have no appetite. You perceive pain more strongly and want to rest. All this serves to save energy, to prepare it for immune defense. A very important aspect, also described here once. We need energy for immune defense. Any energy, power, is used by our body for this immune defense, so that all the cells work and can fight the intruders. The symptoms that you have from a cold can be direct consequences of disinfection, such as coughing, sneezing, like I'm doing now, or consequences that your body wants to use any energy to fight the disease. And that's why you're tired and sluggish. Being tired and sluggish has to do with the fact that your body wants to use all the energy to fight the intruders, the bacteria, the viruses, or has to. And that's why it's so important not to do sports in parallel, or to overexert yourself, or to strain yourself, because then energy is not used to fight the disease. You will be under fire in a country that is turning into a war economy. Because activating the immune system correctly means a blatant... War economy, phew! ...and is very powerful. Just as war is expensive for a country, when the entire industry suddenly has to build tanks, your immune system also costs a huge amount of energy, amino acids, and other substances to produce weapons. Fever, for example. It speeds up your metabolism and makes your cells work harder and faster, while it produces heat that puts many intruders under stress. But it takes a lot of calories to keep up. Yeah, great. Great. So, explained with the fever. I think it's a blatant comparison to the war economy, but as I said, it's very important to explain the importance of fever and its benefits. Intruders such as viruses or bacteria, which multiply best at 37 degrees, the body becomes hotter due to fever, we get 38 degrees, and the proteins clump with some of the pathogens. And as a result, they can no longer multiply as well or die. So fever has a real function. With infections, as we have just seen, our immune system is on the rise. Lymphocytes have an important task, and I'll show you the so-called B-lymphocytes and also the T-lymphocytes, what they do. But these are defensive cells, and these defensive cells sense the viruses, the bacteria, the intruders in the blood and fight them. And in order to sense and fight them, they migrate to the site of the infection, and defend the pathogens there. And fever can accelerate exactly this process, because then so-called heat shock proteins are released, i.e. a turbo boost for the lymphocytes, because they then become faster and can fight the viruses faster or the bacteria, the intruders faster. So fever is basically a useful, important defensive reaction of the body to an infection and does not have to be lowered in any case, or if you have 38 degrees, you shouldn't do that yet, because fever takes on an important task. Normally, the fever drops by itself within a few days, but if the fever lasts longer or the temperature climbs to over 39, over 39.5 degrees, then it is advisable to lower it. So that would be the limit, because then, when the fever rises even further, to 40 degrees, then it not only causes problems for the bacteria and the viruses, but also for yourself, for your protein. Oh, good to hear and to know. If you are young, healthy and fit, you will recover quickly, if you feel better again. But if you are old or still very young, weakened or suffering from a chronic disease, this can be too exhausting. Your body basically eats itself up to maintain its defense. Wow, the body eats itself up. That's exactly why there are references to a warm soup, beef broth, for example, which you often hear about from home cooking. Important. Fluid, electrolytes, especially sodium is in there. It is sweated a lot by fever. Calories, proteins, vitamins and so on, if you throw in vegetables and don't let them boil. So, if you are sick and don't feel like eating, which is very often the case, then try to take good soups with you in small portions. That is exactly the reason, as you have seen here, and medically it is absolutely explainable. And shown here superbly. Otherwise, your body eats itself up. Your body needs energy, and it wins it if you don't eat anything. Logically, for example, from the muscle tissue, from the fat tissue. The best way to train your immune system. Your immune system is unique. Everyone wants a different immune system that is better equipped against some enemies and worse against others. Evolutionarily, this makes sense. Because it prevents our species from being eliminated by a single infection. Important. The immune system of mankind is a spectrum. Most people react well to infections. Some react well above average, and others not well enough and die. There are people who survived the plague. And others are more resistant to HIV, the coronavirus or even Ebola. Again, others are already suffering from the flu. Or they are more susceptible to certain bacterial infections. Crass, again shown really well. So very important. Your immune system is individual, and each of us has a different immune system. Against pathogen A, maybe yours is better than mine. Against pathogen B, but maybe mine is better than yours. You can't generalize that. And I want to come back to what affects our immune system. To the two essential components that make up your immune system and what makes it good or bad. The innate and acquired immune system. These two components determine how your immune system works. You can't influence one, but you can influence the other. The innate immune system is also called the innate immune response. The innate immune system describes the first immune response of our body to intruding pathogens. And usually within a few minutes, the immune system recognizes the threat and fights it. Often it only takes a few hours until the danger is completely eliminated and disposed of. That we have a cold, a flu that lasts several days, that's not so often. But we have thousands of intruders every day. The innate immune response is in many cases sufficient to fight an illness. The components of the innate immune response make up 90% of the total immune response of the body. So it shows that the innate immune response is crucial. The remaining, but often very important, especially over life, 10% are our adaptive immune system. And the adaptive, the acquired immune system, forms the second stage of the pathogen defense. And it only happens if the innate immune response was not successful. Typically with a cold, with a flu. And as a result, it is slower, but more effective in fighting the pathogens. Slower, that is, it takes a while for it to take effect. And only 10% of the pathogen defense, as I said, comes through the adaptive immune defense. Especially new viruses, like the coronavirus, this adaptive immune defense plays an important role. Because it is something completely new for our body. But through constant changes in viruses and bacteria, the body can be threatened by diseases that the innate immune response can no longer defend. And for these cases, the body has developed cells that recognize structures within the pathogen and can also fight them. In order to be prepared for the next attack of the pathogen. That's why we sometimes say, if you've had a certain cold or a disease, then you won't get it anymore. You have developed an immune system, where the pathogens are noticed. And from that point on, these are no longer unknown pathogens. The body has already developed antibodies that are then directly available for the next infection. That's exactly what happened with a corona infection. But the problem can only be when the virus changes extremely again and hardly protects the old infection with the immune system. For example, this is why you get a flu again every year. Influenza. Or every year you have to refresh to get an influenza flu or an influenza vaccine. Because the virus has actually changed again every year. The same was the case with the different corona variants. The idea that you can survive all kinds of diseases because you never caught a cold is wrong. You don't know what your immune system can do until it has to prove it. Getting sick is a game of chance in the casino of life. And the commitment is your health. Always. That doesn't sound very reassuring now, but it's probably the truth. Crass saying somehow. Being sick is normal in the game of chance or casino of life. That's why such a functioning immune system is so important. And that's why it's so important to nurture and care for your own immune system. I'm going to name the three biggest bottlenecks now. And you should have understood why they are important with this video. First, your own way of life. One of the most important factors is enough sleep. Adults need, so to speak, seven to nine hours of as undisturbed sleep as possible. By now they say, those who sleep little live shorter. Also precisely due to the negative impact on the immune system. Undisturbed, what does that mean? That means that during the night you should switch between deep sleep and REM phases. This enables mental regeneration and is also important for the immune system. In addition, good sleep also has a positive effect on the hormone balance. Insomnia, for example, or sleep apnoea can even weaken the immune system. Stress, on the other hand, is really bad for your immune system. You know that too. Stress always sounds so trivial and banal. But so-called distress is proven to be extremely bad for the immune system. That's also part of it. If you have 24-hour shifts and don't sleep at night or do night shifts, that is of course absolutely bad for the immune system. A positive influence, for example, sauna walks, which can strengthen the immune system. Especially the switch from cold showers to warm showers or cold showers and hot sauna walks. This is also important for the immune system. Secondly, sport and exercise. Many endurance sports, especially jogging, cycling, swimming, nordic walking, whatever, promote the immune system. In addition to the muscles, the immune system is also trained here. And the production of the immune system does not decrease. Scientifically, it is not proven why sport helps. Researchers assume that a lot of exercise decreases the inflammatory potential. Secondly, it improves the vascular systems. Vascular systems are also important, so that the cells get to where the pathogens are quickly. Thirdly, the lymphatic fluid is also moved faster. And in this fluid there are immune cells that get to the necessary places in the body faster. Exactly what we have just seen here in the video. And then the third important adjusting screw to strengthen and positively influence the immune system is nutrition. For an optimally functioning immune system, nutrition is probably the most important factor. And as I said, I agree with my advisors. Only a balanced and varied diet offers the body everything to maintain the immune system. In addition to protein, carbohydrates, fats, it is also important to take enough minerals with you. For example, minerals such as calcium, magnesium, trace elements, zinc are essential for the immune system. Some home remedies have also proven themselves and support the function of the immune system. I have just mentioned the use of sauna halls. Changing showers, for example, have a similar function. In addition, there are also different types of tea. Why do I say tea? Because fluidity is very important during a cold. Salvia, eucalyptus, echinacea, especially hot lemon, whatever, which also supports the immune system with a lot of vitamin C. Although it is not clear whether this will reduce the duration of the disease. But very important, you should make sure that the immune system is permanently functioning. So, I hope you are ready for the next cold. Or if you have just caught a cold, like me, when you get sick, it's completely normal. But remember the fever limit of 39 degrees. Rest, no sport, soup, drink a lot of fluids with important nutrients. That's basically what you should do. And that's how I'm going to do it now. Thank you for watching and see you in the next video.
