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. Vaccines, also called immunizations, teach the immune system to make antibodies that fight off infections before they make you sick.

Taking zinc supplements at the beginning of a respiratory infection can reduce the severity and duration of symptoms. Ask your doctor to recommend brands and appropriate dose for you. Joshua Milner, MD , is director of the Division of Pediatric Allergy, Immunology, and Rheumatology and professor of pediatrics at Columbia University Vagelos College of Physicians and Surgeons.

He is a leader in the field of discovery and immunopathogenesis of genetic diseases that lead to allergic symptoms. What You Really Need to Do to Boost Your Immunity. October 20, Share this page Share on Facebook Share on X formerly Twitter Share on LinkedIn Share by email.

Weak immune systems It is almost never the case that your immune system is completely weak, says Milner. How to know if your immune system is weak or strong Unfortunately, most people find out that one part of their immune system is weak when they get an infection.

How to boost your immune system Scientists are studying direct connections between lifestyle choices and strong immune systems. How to keep your immune system strong Milner recommends: Eat as many fresh fruits and vegetables as you can, every day.

Stay physically active with walks and exercise. Certain helpful microbes break down fibers into short chain fatty acids, which have been shown to stimulate immune cell activity.

These fibers are sometimes called prebiotics because they feed microbes. Therefore, a diet containing probiotic and prebiotic foods may be beneficial. Probiotic foods contain live helpful bacteria, and prebiotic foods contain fiber and oligosaccharides that feed and maintain healthy colonies of those bacteria.

Animal studies have found that deficiencies in zinc , selenium , iron , copper, folic acid , and vitamins A , B6 , C , D , and E can alter immune responses.

Epidemiological studies find that those who are poorly nourished are at greater risk of bacterial, viral, and other infections. Eating a good quality diet, as depicted by the Healthy Eating Plate, can prevent deficiencies in these nutrients.

However, there are certain populations and situations in which one cannot always eat a variety of nutritious foods, or who have increased nutrient needs. In these cases a vitamin and mineral supplement may help to fill nutritional gaps. Studies have shown that vitamin supplementation can improve immune responses in these groups.

The elderly are a particularly high-risk group. The immune response generally declines with increasing age as the number and quality of immune cells decreases. This causes a higher risk of poorer outcomes if the elderly develop chronic or acute diseases.

In addition, about one-third of elderly in industrialized countries have nutrient deficiencies. Diet variety may also be limited due to budget constraints or lower interest in cooking for one person; poor dentition; mental impairment; or lack of transportation and community resources to obtain healthy food.

Megadose supplements many times the RDA do not appear justified, and can sometimes be harmful or even suppress the immune system e.

What Is Our Immune System? These barriers include: Skin that keeps out the majority of pathogens Mucus that traps pathogens Stomach acid that destroys pathogens Enzymes in our sweat and tears that help create anti-bacterial compounds Immune system cells that attack all foreign cells entering the body Adaptive or acquired immunity is a system that learns to recognize a pathogen.

Other conditions that trigger an immune response Antigens are substances that the body labels as foreign and harmful, which triggers immune cell activity.

What factors can depress our immune system? Older age: As we age, our internal organs may become less efficient; immune-related organs like the thymus or bone marrow produce less immune cells needed to fight off infections. Aging is sometimes associated with micronutrient deficiencies, which may worsen a declining immune function.

Environmental toxins smoke and other particles contributing to air pollution, excessive alcohol : These substances can impair or suppress the normal activity of immune cells. Excess weight: Obesity is associated with low-grade chronic inflammation.

Fat tissue produces adipocytokines that can promote inflammatory processes. Chronic diseases: Autoimmune and immunodeficiency disorders attack and potentially disable immune cells. Chronic mental stress: Stress releases hormones like cortisol that suppresses inflammation inflammation is initially needed to activate immune cells and the action of white blood cells.

Lack of sleep and rest: Sleep is a time of restoration for the body , during which a type of cytokine is released that fights infection; too little sleep lowers the amount of these cytokines and other immune cells. Does an Immune-Boosting Diet Exist?

Probiotic foods include kefir, yogurt with live active cultures, fermented vegetables, sauerkraut, tempeh, kombucha tea, kimchi, and miso.

Prebiotic foods include garlic, onions, leeks, asparagus, Jerusalem artichokes, dandelion greens, bananas , and seaweed. However, a more general rule is to eat a variety of fruits, vegetables , beans , and whole grains for dietary prebiotics.

Chicken soup as medicine? Is there scientific evidence that it aids in healing? But when breaking down its ingredients, it does appear a worthwhile remedy to try. Second, it provides fluids and electrolytes to prevent dehydration, which can easily occur with a fever. Lastly, a traditional chicken soup recipe supplies various nutrients involved in the immune system: protein and zinc from the chicken, vitamin A from carrots, vitamin C from celery and onions, and antioxidants in the onions and herbs.
