Cassel says most of the things people take to boost their immune system, such as vitamins or supplements, don't have any effect on your immune response.
Diabetes, obesity and smoking can also interfere with your immune system and cause it to not work the way it is supposed to, Dr. Because our immune response to fighting disease, infections and viruses in the body is so complex, there's a lot we don't know about why some people have a more balanced immune response while others don't.
You may not have a lot of control over how your immune system functions, but there are ways to keep from getting sick. Like other illnesses, COVID coronavirus is believed to be mainly spread from person to person.
To prevent illness and avoid being exposed to the virus, the Centers for Disease Control and Prevention CDC recommends washing your hands often, avoiding close contact with people who are sick, covering your mouth and nose with a cloth face cover when around others, covering coughs and sneezes, and cleaning and disinfecting frequently touched surfaces daily.

| Immune balance: the development of the idea and its applications | It is a complex network of cells and organs that work together to protect your body from infection and disease. Your immune cells are continually on patrol, traveling throughout your body looking for infectious invaders and damage. New immune cells are created in your bone marrow. Certain immune cells — called B and T cells — are the special forces of the immune system, playing an important role in the elimination of infectious invaders. Because of this role, these cells undergo a rigorous boot camp during their development to ensure they will not discharge friendly fire on healthy cells in the body. Any B cell or T cell exhibiting activity against the self — or autoreactivity — is killed during training. Millions of newly created B and T cells are killed every day because they fail this training process. If these self-reactive cells escape destruction, they could turn against the body and carry out an inappropriate autoimmune attack. My research investigates how B cells are able to slip past the checkpoints the immune system has in place to guard against autoreactivity. These tolerance checkpoints ensure that autoreactive immune cells are either purged from the body or held in permanent lockdown and unable to engage in inappropriate responses that would target healthy tissue. If the immune system is like a thermostat, turning it up too high results in overactivation and uncontrolled inflammation, while turning it down too low results in a failure to respond to infection and disease. Because sustaining immune balance is critical, tinkering with the immune system through the use of supplements is not a good idea unless you have a clinical deficiency in certain vital nutrients. Not intended to diagnose, treat, cure, or prevent any disease. Eating a well-balanced diet , exercising regularly, reducing stress and getting decent sleep, on the other hand, can help your body maintain a functioning and healthy immune system. Although these lifestyle behaviors are not foolproof, they contribute to overall good health and ultimately to a more healthy immune system. In reality, vaccines are the only safe and effective tool beyond healthy lifestyle behaviors to support your immune system. Vaccines contain harmless forms of pathogens that help to train your immune cells to recognize and fight them. In a world where people are continually bombarded by the marketing mantra that more is better, rest assured that when it comes to the immune system, maintaining perfect balance is just right. There is some evidence that various micronutrient deficiencies — for example, deficiencies of zinc, selenium, iron, copper, folic acid, and vitamins A, B6, C, and E — alter immune responses in animals, as measured in the test tube. However, the impact of these immune system changes on the health of animals is less clear, and the effect of similar deficiencies on the human immune response has yet to be assessed. So, what can you do? If you suspect your diet is not providing you with all your micronutrient needs — maybe, for instance, you don't like vegetables — taking a daily multivitamin and mineral supplement may bring other health benefits, beyond any possibly beneficial effects on the immune system. Taking megadoses of a single vitamin does not. More is not necessarily better. Walk into a store, and you will find bottles of pills and herbal preparations that claim to "support immunity" or otherwise boost the health of your immune system. Although some preparations have been found to alter some components of immune function, thus far there is no evidence that they actually bolster immunity to the point where you are better protected against infection and disease. Demonstrating whether an herb — or any substance, for that matter — can enhance immunity is, as yet, a highly complicated matter. Scientists don't know, for example, whether an herb that seems to raise the levels of antibodies in the blood is actually doing anything beneficial for overall immunity. Modern medicine has come to appreciate the closely linked relationship of mind and body. A wide variety of maladies, including stomach upset, hives, and even heart disease, are linked to the effects of emotional stress. Despite the challenges, scientists are actively studying the relationship between stress and immune function. For one thing, stress is difficult to define. What may appear to be a stressful situation for one person is not for another. When people are exposed to situations they regard as stressful, it is difficult for them to measure how much stress they feel, and difficult for the scientist to know if a person's subjective impression of the amount of stress is accurate. The scientist can only measure things that may reflect stress, such as the number of times the heart beats each minute, but such measures also may reflect other factors. Most scientists studying the relationship of stress and immune function, however, do not study a sudden, short-lived stressor; rather, they try to study more constant and frequent stressors known as chronic stress, such as that caused by relationships with family, friends, and co-workers, or sustained challenges to perform well at one's work. Some scientists are investigating whether ongoing stress takes a toll on the immune system. But it is hard to perform what scientists call "controlled experiments" in human beings. In a controlled experiment, the scientist can change one and only one factor, such as the amount of a particular chemical, and then measure the effect of that change on some other measurable phenomenon, such as the amount of antibodies produced by a particular type of immune system cell when it is exposed to the chemical. In a living animal, and especially in a human being, that kind of control is just not possible, since there are so many other things happening to the animal or person at the time that measurements are being taken. Despite these inevitable difficulties in measuring the relationship of stress to immunity, scientists are making progress. Almost every mother has said it: "Wear a jacket or you'll catch a cold! Probably not, exposure to moderate cold temperatures doesn't increase your susceptibility to infection. There are two reasons why winter is "cold and flu season. Also the influenza virus stays airborne longer when air is cold and less humid. But researchers remain interested in this question in different populations. Some experiments with mice suggest that cold exposure might reduce the ability to cope with infection. But what about humans? Scientists have performed experiments in which volunteers were briefly dunked in cold water or spent short periods of time naked in subfreezing temperatures. They've studied people who lived in Antarctica and those on expeditions in the Canadian Rockies. The results have been mixed. For example, researchers documented an increase in upper respiratory infections in competitive cross-country skiers who exercise vigorously in the cold, but whether these infections are due to the cold or other factors — such as the intense exercise or the dryness of the air — is not known. A group of Canadian researchers that has reviewed hundreds of medical studies on the subject and conducted some of its own research concludes that there's no need to worry about moderate cold exposure — it has no detrimental effect on the human immune system. Should you bundle up when it's cold outside? The answer is "yes" if you're uncomfortable, or if you're going to be outdoors for an extended period where such problems as frostbite and hypothermia are a risk. But don't worry about immunity. Regular exercise is one of the pillars of healthy living. It improves cardiovascular health, lowers blood pressure, helps control body weight, and protects against a variety of diseases. But does it help to boost your immune system naturally and keep it healthy? Just like a healthy diet, exercise can contribute to general good health and therefore to a healthy immune system.

Eating well means emphasizing plenty of fruits and vegetables, lean protein, whole grains, and fat—free or low—fat milk and milk products. Eating well also means limiting saturated fats, cholesterol, salt, and added sugars. Eating well provides multiple nutrients that support optimal immune function. Talk to your health care provider if you think you need nutritional supplements. In a study of more than , US adults, those who met aerobic and muscle-strengthening physical activity guidelines were about half as likely to die from flu and pneumonia as adults who met neither guideline. For adults, weekly physical activity guidelines call for at least minutes of moderate-intensity aerobic activity such as 30 minutes a day for 5 days plus two days of muscle-strengthening activities. Regular physical activity helps you feel better, sleep better, and reduce anxiety. Combined with eating well, physical activity can help a person maintain a healthy weight. Following the physical activity recommendations for your age provides immediate and long—term benefits. For example, being physically active helps protect you from the flu. Emerging research also suggests that physical activity may potentially benefit immunity. Excess weight can affect how your body functions. Obesity, defined as a body mass index BMI of 30 or more in adults, is linked to impaired immune functions. Safe ways to help maintain a healthy weight include reducing stress, eating healthy foods, getting enough sleep, and engaging in regular physical activity. Scientific evidence is building that sleep loss 13 can negatively affect different parts of the immune system. This can lead to the development of a wide variety of disorders. See the recommended hours of sleep per day for your age. Smoking can make the body less successful at fighting disease. Smoking increases the risk for immune system problems, including rheumatoid arthritis. Over time, excessive alcohol use can weaken the immune system.

Immune system balance -
For example, athletes who engage in "blood doping" — pumping blood into their systems to boost their number of blood cells and enhance their performance — run the risk of strokes.
Attempting to boost the cells of your immune system is especially complicated because there are so many different kinds of cells in the immune system that respond to so many different microbes in so many ways.
Which cells should you boost, and to what number? So far, scientists do not know the answer. What is known is that the body is continually generating immune cells.
Certainly, it produces many more lymphocytes than it can possibly use. The extra cells remove themselves through a natural process of cell death called apoptosis — some before they see any action, some after the battle is won.
No one knows how many cells or what the best mix of cells the immune system needs to function at its optimum level. As we age, our immune response capability becomes reduced, which in turn contributes to more infections and more cancer. As life expectancy in developed countries has increased, so too has the incidence of age-related conditions.
While some people age healthily, the conclusion of many studies is that, compared with younger people, the elderly are more likely to contract infectious diseases and, even more importantly, more likely to die from them.
Respiratory infections, including, influenza , the COVID virus and particularly pneumonia are a leading cause of death in people over 65 worldwide. No one knows for sure why this happens, but some scientists observe that this increased risk correlates with a decrease in T cells, possibly from the thymus atrophying with age and producing fewer T cells to fight off infection.
Whether this decrease in thymus function explains the drop in T cells or whether other changes play a role is not fully understood. Others are interested in whether the bone marrow becomes less efficient at producing the stem cells that give rise to the cells of the immune system. A reduction in immune response to infections has been demonstrated by older people's response to vaccines.
For example, studies of influenza vaccines have shown that for people over age 65, the vaccine is less effective compared to healthy children over age 2.
But despite the reduction in efficacy, vaccinations for influenza and S. pneumoniae have significantly lowered the rates of sickness and death in older people when compared with no vaccination. There appears to be a connection between nutrition and immunity in the elderly.
A form of malnutrition that is surprisingly common even in affluent countries is known as "micronutrient malnutrition. Older people tend to eat less and often have less variety in their diets.
One important question is whether dietary supplements may help older people maintain a healthier immune system. Older people should discuss this question with their doctor. Like any fighting force, the immune system army marches on its stomach. Healthy immune system warriors need good, regular nourishment.
Scientists have long recognized that people who live in poverty and are malnourished are more vulnerable to infectious diseases. For example, researchers don't know whether any particular dietary factors, such as processed foods or high simple sugar intake, will have adversely affect immune function.
There are still relatively few studies of the effects of nutrition on the immune system of humans. There is some evidence that various micronutrient deficiencies — for example, deficiencies of zinc, selenium, iron, copper, folic acid, and vitamins A, B6, C, and E — alter immune responses in animals, as measured in the test tube.
However, the impact of these immune system changes on the health of animals is less clear, and the effect of similar deficiencies on the human immune response has yet to be assessed. So, what can you do? If you suspect your diet is not providing you with all your micronutrient needs — maybe, for instance, you don't like vegetables — taking a daily multivitamin and mineral supplement may bring other health benefits, beyond any possibly beneficial effects on the immune system.

In a living animal, and especially in a human being, that kind of control is just not possible, since there are so many other things happening to the animal or person at the time that measurements are being taken.
And those roots run deep. The immune system is a powerful biological force—a liquid organ that permeates our bodies. Diverse immune cells are constantly on patrol, hunting for miscreants to roust: bacteria, viruses, tumors, cellular trash.
The immune system keeps us safe in a hostile world. But not every immune component is poised to attack. Some cells control the response, keeping it from running amok and attacking our own systems.
These checks and balances are critical to healthy immunity. If the response is too weak, a pathogen or cancer can take hold. As the NOMIS Center celebrates its 10th anniversary this year, its researchers are answering many questions to illuminate immune function.
How do different types of T cells respond to their environment, form memory and regulate immunity? Which mechanisms go awry in autoimmune diseases? Can we control infectious diseases without killing microbes? Multidisciplinary researchers Susan Kaech , Björn Lillemeier , Ye Zheng , Janelle Ayres , Greg Lemke and others are investigating new ways to prime the immune system to attack disease or bring overactive cells under control.
The goal? Restore balance. Immune cells are segregated into two major types: innate and adaptive. Innate cells are the first responders.
They recognize a threat, mount an attack and call for help. Soon, the adaptive response kicks in. These cells are custom-designed to meet specific threats.
Even better, the adaptive response remembers pathogens from years before, the mechanism that powers vaccines. While accurate, that description vastly oversimplifies immunity.
Scientists are still delineating the many signals that kick the immune system into high gear or keep it from overreacting. Even the number and types of immune cells are being questioned. That can dictate the types that form. Understanding this diversity is crucial on many levels. The immune response often weakens with age.
Does this reflect fewer immune cells, a loss of diversity or other factors? Similar questions come up with cancer. On a broader scale, Kaech and colleagues are exploring how different immune and non-immune cells communicate.
Immune cells alert other immune cells to potential danger. Normal tissue tells the immune system it is not dangerous. Tumors and pathogens try to fool immune cells into not responding at all.
Understanding these various inputs could offer new tools to control immunity. For example, like people, immune cells may not function optimally when they are hungry. How might the metabolic state of particular non-immune cell types affect nutrient availability for the immune cells, and how does that in turn affect their metabolic state and functionality?
This could be especially important in tumor microenvironments, which can be nutritional deserts. Kaech wants to understand, and ultimately control, these mechanisms to boost the immune response against cancer. DECODING INTERNAL CHIT CHAT. Immune research has been focused on external factors—the pathogens and molecular signals that kick the immune response into high gear.
But what about internal signaling? Mega-dosing specific nutrients, herbs, or botanicals may be useless at best and harmful at worst. And there are no magical quick fixes to reverse the detriments of a nutrition approach filled with highly processed fat and refined grains that are common with frequent takeout orders, fast food, and refined snack foods.
Start with high-quality proteins such as fish, meat and poultry , ample amounts of colorful fruits and vegetables, some healthy fats such as nuts, seeds, and olive oil , and nutrient-dense carbohydrate choices such as lentils or sweet potato.
Then, consider a reasonable, supportive, general supplement regimen. Many of us are overfed from a caloric standpoint and undernourished from a nutrient standpoint. Yes, we need to take reasonable measures to reduce our risk of exposure, such as handwashing regularly and good hygiene practices.
But we also need to remember the importance of sleep and the value of fitness and nutrition on our immune function. Conversely, poor nutrition creates an environment in which the immune system cannot respond well. While there are no guarantees when it comes to health, there is power in risk management.
We each are personally responsible for our nutrition and lifestyle choices and their effects on our health. Leave a comment, ask a question, or see what others are talking about in the Life Time Training Facebook group. Samantha McKinney has been a dietitian, trainer and coach for over 10 years.
