New research shows little risk of infection from prostate biopsies. Discrimination at work is linked to high blood pressure. Icy fingers and toes: Poor circulation or Raynaud's phenomenon? How can you improve your immune system? On the whole, your immune system does a remarkable job of defending you against disease-causing microorganisms.

But sometimes it fails: A germ invades successfully and makes you sick. Is it possible to intervene in this process and boost your immune system?

What if you improve your diet? Take certain vitamins or herbal preparations? Make other lifestyle changes in the hope of producing a near-perfect immune response?

The idea of boosting your immunity is enticing, but the ability to do so has proved elusive for several reasons. The immune system is precisely that — a system, not a single entity. To function well, it requires balance and harmony. There is still much that researchers don't know about the intricacies and interconnectedness of the immune response.

For now, there are no scientifically proven direct links between lifestyle and enhanced immune function. But that doesn't mean the effects of lifestyle on the immune system aren't intriguing and shouldn't be studied. Researchers are exploring the effects of diet, exercise, age, psychological stress, and other factors on the immune response, both in animals and in humans.

In the meantime, general healthy-living strategies make sense since they likely help immune function and they come with other proven health benefits. Immunity in action. A healthy immune system can defeat invading pathogens as shown above, where two bacteria that cause gonorrhea are no match for the large phagocyte, called a neutrophil, that engulfs and kills them see arrows.

Your first line of defense is to choose a healthy lifestyle. Following general good-health guidelines is the single best step you can take toward naturally keeping your immune system working properly.

Every part of your body, including your immune system, functions better when protected from environmental assaults and bolstered by healthy-living strategies such as these:. Many products on store shelves claim to boost or support immunity.

But the concept of boosting immunity actually makes little sense scientifically. In fact, boosting the number of cells in your body — immune cells or others — is not necessarily a good thing. 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. Spinach may boost the immune system, as it contains many essential nutrients and antioxidants, including :.

Vitamins C and E can help support the immune system. Research also indicates that flavonoids may help to prevent the common cold in otherwise healthy people. People use ginger in a variety of dishes and desserts, as well as in teas. According to a review, ginger has anti-inflammatory and antioxidative properties and is likely to offer health benefits.

However, more research is necessary to confirm whether or not it can effectively prevent illness. One review looked at whether taking garlic supplements containing allicin reduced the risk of getting a cold. The group of participants taking a placebo had more than double the number of colds between them than those taking the garlic supplements.

However, the researchers concluded that more research is necessary to determine whether or not garlic can help to prevent colds. Green tea contains only a small amount of caffeine, so people can enjoy it as an alternative to black tea or coffee.

Drinking it may also strengthen the immune system. As with blueberries, green tea contains flavonoids, which may reduce the risk of a cold. Kefir is a fermented drink that contains live cultures of bacteria that are beneficial for health. Initial research suggests that drinking kefir may boost the immune system.

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. Anyone who gets frequent colds or other illnesses and is concerned about their immune system should speak to a doctor.

Stress reduction: Chronic stress can negatively alter immune system responses, making you more likely to get sick. Identify your personal stress reduction strategies and practice them regularly. Sleep: Sleep has a big influence on immune function, so it is essential to get plenty of sleep.

Practice good sleep hygiene and maintain consistent sleep hours—turn off screens, ensure the room is cool, quiet, and dark, and set a reminder to help yourself go to bed on time.

Check out our recorded Sleep workshop here! Exercise: Moderate, regular physical activity helps to boost immune system function by raising levels of infection-fighting white blood cells and antibodies, increasing circulation, and decreasing stress hormones.

Establish and follow an exercise program to not only help prevent respiratory infections but also to improve cognitive and physical resilience. Eat plenty of fruits and vegetables—aim for 10 servings per week.

Include fermented vegetables or other probiotic-containing foods. There are several nutrients, plant-based botanicals, and supplements that can boost immune function and provide symptom relief during illness and may help to shorten the duration of illness.

For preventing and treating viral upper respiratory infections, consider some of the following:. Vitamin C: Vitamin C may help to prevent infections, including those caused by bacteria and viruses.

Regularly administered vitamin C has been shown to shorten the duration of colds, and higher doses of vitamin C during an illness can also act as a natural antihistamine and anti-inflammatory. Vitamin D : Vitamin D, known as the "sunshine vitamin," is one of the most important and powerful nutrients for supporting the immune system.

Numerous studies have shown that it helps reduce the risk of colds and flu. Unfortunately, a high percentage of the population is deficient, so daily supplementation ideally in the form of vitamin D3 offers the best protection.

Vitamin A: For short-term use and particularly for those with moderate vitamin A deficiency, supplementation can be extremely helpful in supporting the body's ability to fight infections, particularly with regard to respiratory infections. Zinc: Zinc plays a significant role in boosting immunity.

Often available as lozenges, zinc can help to reduce the frequency of infections as well as the duration and severity of the common cold when taken within 24 hours of onset. Selenium: Selenium, a key nutrient for immune function, is also an antioxidant that helps boosts the body's defenses against bacteria, viruses, and cancer cells.

Top Immune System Boosters Your immune system is a process of checks and balances that helps fight and protect the body from disease and illness. Foods can certainly boost the immune system. Specifically, try to eat a variety of fruits, vegetables, whole grains, dairy products and lean protein.

Also, fit in foods with omega-3 fatty acids, like eggs, salmon and avocados, as well. All these foods will not only build up parts of your immune system, but can help you maintain a healthy weight.

Drinking plenty of water. Water intake can have many positive benefits for your immune system, including but not limited to aiding in digestion and preventing possible pathogens like a virus or bacteria from getting into the eyes, nose and mouth. Prioritizing exercise. Moderate-intensity exercise can help maintain a healthy immune system.

Getting enough sleep. If you get enough sleep, it will help your body fight off sickness and help succeed at the tips mentioned above. Adults should get between hours of sleep each night.

Increasing vitamin intake. Vitamins B6, C and E are all known for their immune-boosting properties. It also contains amino acids that may aid in the production of germ-fighting compounds in your T-cells, which reduces inflammation in the body and helps fight infection.

Green tea can be consumed hot, cold or as matcha powder. Vitamin D can be found in salmon, canned tuna, egg yolks, and mushrooms.

Your body can also synthesize vitamin D with just minutes of sunshine three times a week. Yogurt, Kombucha, Sauerkraut, Kimchi, Pickles, Tempeh Fermented Soybeans , and certain types of cheese contain live cultures, also known as probiotics, which are thought to help stimulate the immune system to fight off disease.

The microbiome helps you process the nutrients described throughout the rest of this article, while also acting as an extra barrier for fighting off harmful bacteria and fungi.

Garlic contains compounds that help the immune system fight germs in a variety of ways by stimulating cells important to fighting disease and helping to regulate the immune system. It helps boost the production of virus-fighting T-cells and can reduce the amount of stress hormones your body produces which can help keep your immune system functioning at full strength.

Vitamin B-6 is essential in the formation of new and healthy red blood cells, and aids in maintaining the lymphatic system. Chicken, turkey, cold-water fish salmon and tuna , chickpeas traditional hummus , bananas, fortified breakfast cereal, and nutritional yeast are great options for consuming vitamin B Water helps produce lymph which carries white blood cells and other immune system cells through the body.

There are many foods with high water content such as cucumbers, watermelon, and celery. If you have a hard time drinking plain water, try a cup of green tea with lemon, watermelon, cucumber or mint-infused water for an immune system powerhouse beverage.

Think of proper hydration as a way to make it easier for immune-boosting nutrients to get to where they need to go cells in your body. Immune system cells need zinc to function as they are intended. Zinc is a mineral that our body does not store or produce.

While oysters have the highest food content of zinc, there are several other options such as shellfish crab, clams, lobster, and mussels , poultry chicken or turkey , red meat and beans. Zinc is also found in fortified cereals and some breads, but the best absorption comes from animal-based foods.

As you take stock of this information, consider layering the practice of mindful eating to your plan. Mindful eating is a way to be present, focused and tuned in to the pleasure of eating.

This practice can also help decrease stress which can adversely affect your immune system. As you sit down to enjoy your meals, possibly with friends or family members, take time to consider where your food came from, the journey the food took to get to your plate, its taste, texture, and aroma.

The practice of mindful eating helps us slow down, stay in the moment and reconnect to the food that fuels our bodies. Bon appetit!

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.

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. As a service to our readers, Harvard Health Publishing provides access to our library of archived content.
