What "Immune Boosting" Really Means + 18 Ways To Stay Healthy

Beyond washing your hands and getting more sleep, which are incredibly important practices, here are 18 unexpected but effective activities that can help strengthen your immunity, not just supercharge it.

Drinking water "will help keep lungs moist and mucus flowing, clearing lungs of the gunk that can collect and create conditions for opportunistic infections to thrive," wrote functional medicine doctor and mbg Collective member Frank Lipman, M.D., on his website.

Certain teas, like green tea and black tea, have antioxidant polyphenols, which have been known to support the immune system by fighting free radicals2.

Eating a healthy diet, and limiting (or eliminating) inflammatory foods, like sugar, "not only helps your body recover faster—it also helps build up your immune military so it's more resilient and dynamic," Amy Shah, M.D., wrote in an mbg article.

Moday told us avoidance of drugs and alcohol is one of the most important ways to strengthen our immunity, as it affects both sleep3 and hydration. Limit your alcohol intake by swapping a cocktail for a mocktail.

Pull out a cookbook (here are some of our favorite cookbooks), or find a recipe online and commit to cooking at least one new dish each week. Not only will this break the monotony of healthy meal prep, but you'll introduce your body to new foods, which can increase the diversity of your gut microbiome4.

Reading a book before bed rather than looking at your phone, laptop, or an e-book will limit your exposure to blue light, which has been known to suppress melatonin and interfere with sleep.

Studies have proved music across all genres can induce physical and mental states conducive to sleep5.

If you have a hard time falling or staying asleep, consider taking a supplement before crawling into bed. Magnesium glycinate (or magnesium bisglycinate), for example, acts as a natural calcium channel blocker, which promotes muscle relaxation.*

According to research, warms baths can help maintain your body's natural temperature6, which supports your circadian rhythm.

Take a few whiffs of essential oils, or drop them into a diffuser before bedtime. Lavender oil, in particular, can help support quality slumber7 in healthy men and women.

According to breathwork teacher Gwen Dittmar, deep breathing helps to activate the vagus nerve, which turns on the parasympathetic nervous system and helps manage anxiousness or stress.

People who practice meditation are able to recover from physiological stress responses8 much more quickly than those who don't meditate.

Taking a hemp multi+ supplement can help manage anxious thoughts and daily stress, and the addition of vitamin D helps support healthy immune function9.*

Vitamin D deficiency has been linked to people with anxiety and depression10, so soaking up natural sunlight whenever possible can help to improve mood and overall health. Walking is an added cardiovascular bonus.

Having a social support system has been proven to help people manage feelings of anxiousness, so if you're staying inside to avoid potential exposure, calling friends and family is one way to maintain that quality social interaction.

If you're trying to avoid contact with infectious germs, going to a workout class might be out of the question for you. However, exercise can increase short-chain fatty acids, which Will Bulsiewicz, M.D., MSCI, called the "key to gut health," even if it is in the comfort of your home.

Prebiotics help nourish your gut's healthy bacteria, and probiotics help feed those good bacteria and support gut health.* Getting enough of both is helpful for immunity since, according to Lipman, "a healthy gut makes the rest of you less vulnerable to bacterial and viral invaders."

Certain spices, like clove, oregano, thyme, cinnamon, and cumin not only make your meals more interesting, but they also have antibacterial and antifungal properties11, which can help support immunity.

"You can do and take things for each of these areas," Moday said, "but there is no magic bullet for immunity." Maintaining a healthy lifestyle by implementing some of these practices can help strengthen your immunity and prepare your body for exposure to unwanted pathogens.
