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.
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.
No direct links have been identified between lifestyle and enhanced immune response, but researchers have investigated the effect of factors, such as exercise, diet, and stress on the response of the immune system.
The best thing you can do to maintain your immune system is to adopt healthy living strategies that will benefit the entire body, including your immune system. These strategies might include:. Consuming a balanced diet and eating the recommended amounts of nutrients will help maintain normal immune function.
Vitamins A, C, and D, and minerals — including zinc — play a role in the functioning of the immune system.
If you eat a balanced diet, you will have no need to take supplements of these vitamins and minerals and taking extra will not particularly help your immune system.
Populations that are malnourished are known to be more susceptible to infection, and there is some evidence that deficiencies in certain micronutrients alter immune responses.
For example, zinc deficiency — which may contribute to chronic diseases — has been demonstrated to negatively impact how the immune system responds to inflammation in older adults.
Vitamin D supplementation has been linked with alterations in the behavior of the immune system. Taking vitamin D supplements during pregnancy — a period where the immune system is in continual flux — may modify the immune system of the newborn in such a way that protects against respiratory infections and asthma.
Research suggests that vitamin D activates T cells that can identify and attack cancer cells and protect against colorectal cancer in some people. In older adults, vitamin D has also been shown to reduce respiratory infections.
Soluble fiber switches immune cells from pro-inflammatory to anti-inflammatory, which helps us to heal faster from infection. Pterostilbene and resveratrol, found in blueberries and red grapes, respectively, help raise the expression of the human cathelicidin antimicrobial peptide CAMP gene, which is involved in immune function.
The CAMP gene plays a vital role in the innate immune system. Probiotics may help counteract the adverse effects of broad-spectrum antibiotics by keeping the immune system ready to respond to new infections.
Fish oil rich in DHA has been found to enhance B cell activity, which could be promising for those with compromised immune systems. Prolonged fasting has been linked with stem cell regeneration of older and damaged immune cells. High fat and high-calorie diets trigger a response from the immune system similar to a bacterial infection.
Just like eating a healthy diet, regular physical activity contributes to overall good health and, therefore, a healthy immune system. Exercise promotes efficient blood circulation, which keeps the cells of the immune system moving so that they can effectively do their job.
One study revealed that just 20 minutes of moderate exercise stimulated the immune system, which, in turn, produced an anti-inflammatory cellular response. The investigators noted that their finding has encouraging implications for people with chronic diseases — including arthritis and fibromyalgia — and obesity.
Other research discovered that the best way to avoid adverse immune system changes and help the body to recover after intense exercise was to consume carbohydrates during or after.
The authors of the paper suggest that between 30 and 60 grams of carbs every hour during physical activity can help maintain normal immune function.
In addition to a balanced diet and regular exercise, scientists have found evidence of other factors that may affect the response of the immune system. Getting outside in the sunlight may benefit the immune system. Researchers discovered that sunlight energizes infection-fighting T cells that play a key part in immunity.
A study uncovered that anticipating a happy or funny event increased levels of endorphins and other hormones that induce a state of relaxation. Chronic stress can suppress the response of the immune system and its ability to fight disease; therefore, reducing stress may help to prevent infections and other disorders.
Singing in a choir for 1 hour was reported to reduce stress, improve mood, and increase the levels of immune proteins in individuals with cancer and their caregivers.
The study findings demonstrate that something as simple as singing can help reduce the stress-related suppression of the immune system. Research indicated that individuals who were lonely produced higher levels of proteins related to inflammation in response to stress than those who felt they were socially connected.
Although many questions remain about the function of the immune system, it is clear that consuming a healthy diet, regularly exercising, getting adequate sleep, and reducing stress will go a long way to ensuring your immunity is maintained.

Emerging research suggests that added sugars and refined carbs may contribute disproportionately to overweight and obesity 16 According to an observational study in around 1, people, people with obesity who were administered the flu vaccine were twice as likely to still get the flu than individuals without obesity who received the vaccine Curbing your sugar intake can decrease inflammation and aid weight loss, thus reducing your risk of chronic health conditions like type 2 diabetes and heart disease 19 Given that obesity, type 2 diabetes, and heart disease can all weaken your immune system, limiting added sugars is an important part of an immune-boosting diet 1821 This equals about 2 tablespoons 25 grams of sugar for someone on a 2,calorie diet.
Added sugars contribute significantly to obesity, type 2 diabetes, and heart disease, all of which can suppress your immune system. Lowering your sugar intake may decrease inflammation and your risk of these conditions. Although prolonged intense exercise can suppress your immune system, moderate exercise can give it a boost.
Studies indicate that even a single session of moderate exercise can boost the effectiveness of vaccines in people with compromised immune systems Examples of moderate exercise include brisk walkingsteady bicycling, jogging, swimming, and light hiking.
Most people should aim for at least minutes of moderate exercise per week Moderate exercise can reduce inflammation and promote the healthy turnover of immune cells. Jogging, biking, walking, swimming, and hiking are great options. Dehydration can cause headaches and hinder your physical performance, focus, mood, digestion, and heart and kidney function.
These complications can increase your susceptibility to illness To prevent dehydration, you should drink enough fluid daily to make your urine pale yellow. You may need more fluids if you exercise intensely, work outside, or live in a hot climate Older adults need to drink regularly even if they do not feel thirsty.
Relieving stress and anxiety is key to immune health. Long-term stress promotes inflammation, as well as imbalances in immune cell function 79. In particular, prolonged psychological stress can suppress the immune response in children Activities that may help you manage your stress include meditationexercise, journaling, yoga, and other mindfulness practices.
You may also benefit from seeing a licensed counselor or therapist, whether virtually or in person. Lowering your stress levels through meditation, yoga, exercise, and other practices can help keep your immune system functioning properly.
Thus, you should only purchase supplements that have been independently tested by third-party organizations like United States Pharmacopeia USPNSF International, and ConsumerLab.

According to a review , various studies have shown that regular consumption of kefir can help with:. The majority of the research that supports this was carried out on animals or in a laboratory. Researchers need to perform additional studies to understand how kefir may prevent disease in humans. Sunflower seeds can make a tasty addition to salads or breakfast bowls. They are a rich source of vitamin E , an antioxidant. In the same way as other antioxidants, vitamin E improves immune function. It does this by fighting off free radicals, which can damage cells. Almonds are another excellent source of vitamin E. They also contain manganese, magnesium , and fiber. A small handful or a quarter of a cup of almonds is a healthful snack that may benefit the immune system. Oranges and kiwis are an excellent source of vitamin C, which is the vitamin that many people turn to when they feel a cold developing. While scientists are still not sure exactly how it helps, vitamin C may reduce the duration of common cold symptoms and improve the function of the human immune system. For people trying to avoid the sugar in fruit, red bell peppers are an excellent alternative source of vitamin C. Stir-frying and roasting both preserve the nutrient content of red bell peppers better than steaming or boiling, according to a study on cooking methods. That said, it is important to remember that the immune system is complex. Eating a healthful, balanced diet is just one way to support immune health. It is also essential to be mindful of the other lifestyle factors that may affect immune system health, such as exercising and not smoking.

| How to boost your immune system - Harvard Health | We find out. The immune system is a network of special cells, tissues, proteins, and organs that work together to protect the body from potentially damaging foreign invaders and disease. When our immune system functions properly it detects threats, such as bacteria, parasites, and viruses, and it triggers an immune response to destroy them. Our immune system can broadly be divided into two parts: innate and adaptive. Innate immunity is the natural protection that we are born with and our first line of defense to combat infection. Upon detecting an infection, our innate response acts quickly to try and flush out the invader by producing extra mucus or cranking up the thermostat to blast it with a fever. Adaptive immunity is protection that we gain throughout life as we are exposed to diseases or protected against them from vaccinations. The adaptive system spots an enemy and produces the specific weapons — or antibodies — that are required to destroy and eliminate the invader from the body. The adaptive system can take between 5 and 10 days to identify the antibodies that are needed and produce them in the numbers required to attack an invader successfully. In that time, the innate system keeps the pathogen at bay and prevents it from multiplying. If the innate response were stimulated, you would feel constantly unwell with a runny nose, fever, lethargy, and depression. The efficiency of the adaptive response can be sped up with vaccinations. A vaccine contains a harmless version of the germ from which you need protection. The adaptive system remembers the invader so that the next time it comes into contact with the germ, it can act quickly to launch an attack. While many products claim to boost immunity, the concept makes little sense scientifically. Attempting to boost cells of any kind is not necessarily a good thing and may result in serious side effects. The immune system, in particular, contains several different types of cells that respond to various microbes in many ways. Which cells would you boost and to how many? This is a question to which scientists currently do not know the answer. What researchers do know is that the body continuously makes immune cells that are called white blood cells, or leukocytes, and it generates far more cells of the adaptive system — known as lymphocytes — that mature into B cells and T cells than are needed. The excess cells destroy themselves through a process of natural cell death, called apoptosis. It is unknown what is the best mix of cells or optimum number for the immune system to work at its best. For many people, the immune system works well to regulate itself and does not need any help. However, in some people, medications or immune system disorders cause overactivity or low activity of the immune system. Disorders of the immune system are treated with specific medications that tackle the symptoms and associated infections. The primary components of the immune system include the lymph nodes, tonsils, spleen, bone marrow , and thymus. There remains much to learn about the interconnectedness and intricacies of the immune response, however. To function well, the whole system requires harmony and balance. The immune system is not a single entity or force field that needs patching up to work properly. No direct links have been identified between lifestyle and enhanced immune response, but researchers have investigated the effect of factors, such as exercise, diet, and stress on the response of the immune system. The best thing you can do to maintain your immune system is to adopt healthy living strategies that will benefit the entire body, including your immune system. These strategies might include:. Consuming a balanced diet and eating the recommended amounts of nutrients will help maintain normal immune function. Vitamins A, C, and D, and minerals — including zinc — play a role in the functioning of the immune system. If you eat a balanced diet, you will have no need to take supplements of these vitamins and minerals and taking extra will not particularly help your immune system.
