Most studies show that dietary supplements are only useful if you have a deficiency in a nutrient. Taking supplements on top of a healthy diet does not add much to your immune system. Note that most supplements are not superior to the nutrients you can get from food.

Studies show the immune system is very responsive to exercise. Exercise and immune regulation are interrelated and affect each other. Exercise changes immune regulation by affecting cells and has anti-inflammatory effects. Sleep loss reduces natural killer cell activity, which increases the risk for cancer and viral infections; generates production of inflammatory cytokines, which increases the risk for cardiovascular and metabolic disorders; and reduces production of antibodies, which increases the risk for infections.

Stress of all sorts—psychological and physical—directly weakens parts of your immune system, increasing risk for infections or reactivation of viruses inside you. Shingles, a painful rash that arises from the reactivated chickenpox virus, often flares up when people are experiencing chronic stress.

Stress can also cause "patrols" in your immune system—certain cells that tell the immune system to wind down an attack—to fail. When this happens, too much inflammation can occur.

Studies display that getting enough vitamin C along with zinc in your diet may help reduce the symptoms of respiratory infections and shorten the duration of illnesses like the common cold and bronchitis. The best vitamin C foods to add for a strong immune system include:. Beta-carotene has powerful antioxidant activity, allowing it to help reduce inflammation and fight oxidative stress. Instead of taking beta-carotene supplements, researchers propose that beta-carotene can promote health when taken at dietary levels by eating foods rich in the carotenoid. The richest sources of beta-carotene are yellow, orange and red fruits and veggies, along with leafy greens. Adding the following foods to your diet can help promote a strong immune system:. Probiotics are good bacteria that help you digest nutrients that boost the detoxification of your colon and support your immune system. Research published in Critical Reviews in Food Science and Nutrition suggests that probiotic organisms may induce different cytokine responses. Supplementation of probiotics in infancy could help prevent immune-mediated diseases in childhood by improving the gut mucosal immune system and increasing the number of immunoglobulin cells and cytokine-producing cells in the intestines. Vitamin D can modulate the innate and adaptive immune responses, and a vitamin D deficiency is associated with increased autoimmunity as well as an increased susceptibility to infection. Research proves that vitamin D works to maintain tolerance and promote protective immunity. There have been multiple cross-sectional studies that associate lower levels of vitamin D with increased infection. One study conducted at Massachusetts General Hospital included 19, participants, and it showed that individuals with lower vitamin D levels were more likely to report a recent upper respiratory tract infection than those with sufficient levels, even after adjusting for variables such as season, age, gender, body mass and race. Zinc supplements are often used as an over-the-counter remedy for fighting colds and other illnesses. This mineral may help reduce cold-related symptoms and shorten the duration of the common cold. Research evaluating the efficacy of zinc shows that it can interfere with a molecular process that causes bacteria buildup in the nasal passages. Myrrh is a resin, or sap-like substance, that is one of the most widely used essential oils in the world. Historically, myrrh was used to treat hay fever, clean and heal wounds, and stop bleeding. Studies conclude that myrrh strengthens the immune system with its antiseptic, antibacterial and antifungal properties. Researchers expressed that myrrh oil has anti-infective properties and can help boost your immune system. Oregano essential oil is known for its healing and immune-boosting properties. It fights infections naturally due to its antifungal, antibacterial, antiviral and anti-parasite compounds. A study published in Critical Reviews in Food Science and Nutrition found that the main compounds in oregano that are responsible for its antimicrobial activity include carvacrol and thymol. Several scientific studies have shown that oregano oil exhibited antibacterial activity against a number of bacterial isolates and species, including B. laterosporus and S. Incorporating physical activity into your daily and weekly regimen is extremely important to strengthen your immune system. A human study published in Aging Cell revealed that high levels of physical activity and exercise improve the immunosenescence gradual deterioration of the immune system in older adults aged 55 through 79 compared to those in the same age group who were physically inactive. Studies prove that chronic stress can suppress protective immune responses and exacerbate pathological immune responses. In order to promote health and healing, you need to minimize your stress levels. In fact, research analyzing the vulnerability of sleep-deprived adults found that those who slept less than six hours a night were more than four times likely to get a cold than adults who slept more than seven hours. To reduce your chances of catching colds and the flu, make sure you get at least seven hours of sleep every night. Consuming too much alcohol can certainly impact immune function, which is why you need to cut back on alcohol to fight infections and promote immune system health. Alcohol negatively impacts gut health, decreasing immune function and making you more susceptible to harmful pathogens. Stick to one or two alcohol drinks a week or less to boost your immune system.

15 Foods That Boost the Immune System: Citrus, Bell Peppers & More	A study conducted at the University of Wisconsin Medical School found that echinacea demonstrates significant immunomodulatory activities. After reviewing several dozen human experiments, including a number of blind, randomized trials, researchers indicated that echinacea has several benefits, including immunostimulation, especially in the treatment of acute upper respiratory infection. The berries and flowers of the elder plant have been used as medicine for thousands of years. He used elderberry because of its wide array of health benefits, including its ability to fight colds, the flu, allergies and inflammation. Several studies indicate that elderberry has the power to boost the immune system, especially because it has proven to help treat the symptoms of the common cold and flu. A study published in the Journal of International Medical Research showed that when elderberry was used within the first 48 hours of onset of symptoms, the extract reduced the duration of the flu, with symptoms relieved on an average of four days earlier. Plus, the use of rescue medication was significantly less in those receiving elderberry extract compared with placebo. Astragalus is a plant within the bean and legumes family that has a very long history as an immune system booster and disease fighter. Its root has been used as an adaptogen in Traditional Chinese Medicine for thousands of years. Although astragalus is one of the least studied immune-boosting herbs, there are some preclinical trials that show intriguing immune activity. A recent review published in the American Journal of Chinese Medicine found that astragalus-based treatments have demonstrated significant improvement of the toxicity induced by drugs, such as immunosuppressants and cancer chemotherapeutics. Researchers concluded that astragalus extract has a beneficial effect on the immune system, and it protects the body from gastrointestinal inflammation and cancers. The ginseng plant, belonging to the Panax genus, can help you boost your immune system and fight infections. The roots, stems and leaves of ginseng have been used for maintaining immune homeostasis and enhancing resistance to illness or infection. Ginseng improves the performance of your immune system by regulating each type of immune cell, including macrophages, natural killer cells, dendritic cells, T cells and B cells. It has also proved to possess antimicrobial compounds that work as a defense mechanism against bacterial and viral infections. Antibodies bind to antigens, such as toxins or viruses, and keep them from contacting and harming normal cells of the body. Bone broth supports immune function by promoting the health of your gut and reducing inflammation caused by leaky gut syndrome. The collagen and amino acids proline, glutamine and arginine found in bone broth help seal openings in the gut lining and support its integrity. We know that gut health plays a major role in immune function, so consuming bone broth works as an excellent immune system booster food. Ginger root and ginger essential oil can treat a wide range of diseases with its immunonutrition and anti-inflammatory responses. Research shows that ginger has antimicrobial potential , which helps in treating infectious diseases. Studies evaluating the efficacy of green tea show that it contains antioxidant and immunomodulatory properties. It works as an antifungal and antivirus agent and may be helpful for immunocompromised patients. Strengthen your immune system by drinking a high-quality green tea daily. The antioxidants and amino acids present in this tea help your body fight germs and get well.

In the quest for how to boost your immune system, proceed with some caution. If you are using these immune-boosting herbs, supplements and essential oils, remember that the products are extremely potent and should not be taken for more than two weeks at a time.

Giving yourself a break in between long doses is important. Also, if you are pregnant, be cautious when using essential oils, and reach out to your health care provider before doing so. Popular Posts All Time This Week {position} Detox Your Liver: A 6-Step Liver Cleanse.

More Health Dr. Axe on Facebook Dr. Axe on Twitter 70 Dr. Axe on Instagram Dr. Axe on Google Plus Dr. With that in mind, Health reached out to healthcare providers to find the top immune-boosting habits they recommend.

Some of those habits can help block the initial infection. And others fire up your system, so you can get better quickly if you come down with something. All in all, here are simple and easy habits to incorporate into your day-to-day routine to keep your immune system strong.

Research has found that the following foods have some immune-boosting effects:. Focus on dark green, red, and yellow veggies and fruits to help fortify your system with phytochemicals, Lisa Ballehr, DO , a functional medicine practitioner based in Mesa, Ariz.

Some evidence suggests that phytochemicals act like antioxidants, helping fight viruses. Aim for nine to 10 servings a day, said Dr.

To boost your immunity, stock up on foods that have anti-inflammatory effects on the body. Many foods have both antioxidant and anti-inflammatory properties.

A good place to look for anti-inflammatory properties is foods high in omega-3 fatty acids, such as oily fish like salmon, mackerel, tuna, and sardines. Research has found that foods with omega-3 fatty acids are known to help hinder processes in the body that promote inflammation.

Other anti-inflammatory food options include:. The bacteria in your gut may affect your body's ability to fend off infections. So, eating foods that contain "good" bacteria, organisms that are beneficial for gut health, Timothy Mainardi, MD , an allergist and immunologist based in New York, told Health.

Fermented foods and beverages—think kombucha and kimchi—are chock-full of "good" bacteria, also known as probiotics. You could also consider a probiotic supplement. However, research has found that some probiotic foods and supplements may be unsafe for people with weakened immune systems—including those with chronic health conditions or undergoing chemotherapy.

If you have concerns, check with a healthcare provider before taking probiotics. The body needs zinc to support the immune system, said Dr. Additionally, zinc helps with wound healing. The recommended amount of zinc is 13 milligrams for adult men and 9.

Typically, you can get enough zinc from foods like:. Still, it may help to consider taking a zinc supplement after talking to a healthcare provider, suggested Dr. A healthcare provider may test your blood to see if you aren't getting enough zinc from your diet.

Hydration is key to a healthy body and immune system. Water serves several essential functions in the body, including:. It's also important to drink plenty of fluids when you're ill. Water replenishes the fluid you're losing through your lungs every time you cough and from losses due to sweating.

Moderate alcohol consumption doesn't appear to positively affect your immune system. And some evidence suggests that binge drinking, or more than four drinks in two hours for women and five for men, impairs immunity. And while there does not seem to be any good data measuring white blood cell levels for smaller amounts of alcohol, it is assumed that even one or two drinks can blunt your immune system response.

As for heavy drinking, a study published in in Alcohol Research: Current Reviews found a link between alcohol use disorder and a possible susceptibility to pneumonia.

So, if you're working hard to stay healthy, it's best to avoid or limit alcohol. One study published in in the Journal of Sports and Health Science described the following benefits of moderate to vigorous exercise:.

In contrast, research has found that people with sedentary lifestyles are more likely to get colds or other infectious illnesses. The Centers for Disease Control and Prevention CDC recommends minutes of moderate-intensity aerobic activity weekly. Or, if you prefer vigorous exercise, the CDC recommends 75 minutes at that intensity.

A to minute at-home workout , jump rope or jog-in-place session, or a brisk walk around the neighborhood several times a week are good ways to work some sweat into your schedule.

For example, in one study published in in Nature and Science of Sleep , researchers found disrupted sleep caused serious health ramifications, including:.

Also, don't assume you can just catch up on sleep after a night or two of staying up late or tossing and turning. Remember, your body is busy at rest, and it's designed to sleep when the sun goes down. According to the National Sleep Foundation, adults between 18—64 need seven to nine hours of sleep per night.

Also, older adults need seven to eight hours, and children and adolescents require even more sleep. Aim for the right amount for your age group, and be as consistent as possible. Turning in and waking up at roughly the same time every day is healthier than an all-over-the-place sleep schedule.

Unchecked stress, anxiety, worry, and panic pack have many negative health effects. And suppressing the immune system is one of them, said Dr. Prolonged stress also drives up levels of the hormones cortisol and adrenaline.

Eventually, too much of those hormones can inflict damage on the body. The idea of boosting your immune system is appealing, but is it even possible to build up your immune system so that you rarely get sick?

Suzanne Cassel , an immunologist at Cedars-Sinai , says that the concept of boosting your immune system is inaccurate. There's also widely held confusion about how your immune system functions and how your body is designed to combat diseases and infections.

Your immune system works to recognize and identify an infection or injury in the body. This causes an immune response, with the goal of restoring normal function. Cassel says many people think that when they get sick, their symptoms are a sign that they have a virus or an infection.

However, your symptoms are actually a sign that your body is fighting back against the infection or virus, triggering an immune response. Cassel says. Why doesn't my immune system work? Cassel says another common misconception is having a "strong" immune system is what's best for your body.

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.
