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.

A note on COVID The COVID pandemic is creating a range of unique and individual impacts—from food access issues, income disruptions, emotional distress, and beyond.

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.

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.

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.
