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. Sleep for at least seven hours a night. When the body does not get enough sleep, the immune system is negatively affected.

Minimize stress. 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.

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. You can take small steps to help chill and unwind, including:.

Excessive social media usage might increase your stress and anxiety. Still, screen time watching a movie you love or a binge session of your favorite TV show can help take your mind off things. When it comes to keeping your immune system strong, proper handwashing is one of the most important things.

But if you can't get to soap and water, hand sanitizer is the next best thing. Plain old soap and water are all you need. It's important to scrub up for at least 20 seconds—the length of singing "Happy Birthday" twice.

Per the CDC, that's the minimum time needed to significantly reduce the number of microorganisms on your skin. But no matter how good your handwashing skills are, they won't help prevent infection unless you know when to scrub up.

In other words, that includes after using the restroom, sneezing, or coughing. Also, wash your hands before you prepare food, after caring for a sick loved one, treating a wound, or touching any publicly used door handles, knobs, switches, or surfaces, added Dr.

And if your hands are prone to dry skin, the right moisturizer can help. If you don't have access to soap and water, hand sanitizer can help kill most microorganisms. Just be sure to take a peek at the alcohol percentage first.

Alcohol is the active ingredient working to kill viruses and bacteria. You may be unable to avoid viruses and bacteria that spread the common cold and flu entirely. But you can avoid them as best you can by strengthening your immune system.

Focusing on nutrition, hygiene, and other health habits is the key to doing so. These simple immune-boosting habits can help you steer clear of some infections.

Others can supercharge your immune system, so you can get better quickly if you get sick. Dietary supplements are minimally regulated by the FDA and may or may not be suitable for you. The effects of supplements vary from person to person and depend on many variables, including type, dosage, frequency of use, and interactions with current medications.

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.

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. 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.
