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. 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.

Vitamin D supplements have a bit more evidence for their potential benefits. A systematic review of randomized controlled trials published in the British Medical Journal in found that daily intake of vitamin D supplements protected against acute respiratory infections.

Yet, there are many proven ways to strengthen your immune system outside of supplements like vitamin C and vitamin D, Ben-Aderet says. And if you really want to try vitamin C or vitamin D supplements, Ben-Aderet says: "The jury's still mostly out [on their effectiveness], and vitamin supplementation is cheap and mostly harmless.

If you decide to take vitamin C supplements, you should make sure you don't exceed 2, milligrams of vitamin C in a day, Mafi notes. Too much vitamin C can cause stomach issues like nausea and vomiting and kidney stones, according to Mayo Clinic.

Harvard T. Chan's School of Public Health's hub for nutrition information, The Nutrition Source , recommends a dietary allowance for adults 19 years and older of 90 milligrams for men and 75 milligrams for women.

To get vitamin C, you can eat citrus fruits like oranges, grapefruit and lemons, he notes. Certain greens like kale and broccoli also have great amounts of vitamin C. Taking "roughly to international units IUs of vitamin D per day," is a way to safely address a deficiency, Dr.

Jad Sfeir , a Mayo Clinic endocrinologist, told CNBC Make It in August of It's best to find ways to get the vitamin in your diet from foods, Sfeir said, including fortified milk, orange juice or fatty fish like salmon or mackerel.

Having more than 4, IUs per day can increase your risk of toxicity, by greatly elevating the amount of calcium in your bloodstream and urine, Sfeir noted. 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. Over time, excessive alcohol use can weaken the immune system.
