Fighting off germs is busy work for our immune systems, but we can make it easier on ourselves. Discover how small lifestyle choices can keep our immune systems ready for action—and make a big difference in our long-term health.
According to Lisa Osborne, an assistant microbiology and immunology professor, there are simple things we can do to keep our immune systems strong. They come down to listening to what your mother told you growing up: “Activity, healthy diet, sunlight when you can get it. We know these are critical factors for mental health as well as physical health and supporting immune function,” she says.
1. Eat well
Healthy immunity starts on your plate. Focus on whole grains, fresh produce in an array of colors, and healthy proteins such as nuts and seeds to help your body produce infection-fighting white blood cells.
2. Get moving
Regular, moderate physical activity bolsters the immune system and its ability to fight off illnesses, including cold and flu viruses. According to the World Health Organization, adults should aim for 150 to 300 minutes of moderate-intensity aerobic exercise, or 75 to 150 minutes of vigorous aerobic exercise each week, with two sessions of strength training for best overall health.
3. Get some sleep
A good rule of thumb is to aim for at least seven hours of sleep each night. If you’re having trouble sleeping, set a consistent schedule, and avoid screens, alcohol, caffeine, and large meals before bed. If worry is keeping you awake, keep a notebook beside your bed to clear your head. Meditation practice may also help prepare your mind and body for bed.
4. Tackle stress
Too much stress can disturb your immune response and lower your protection against infectious illnesses. To help lighten the load try meditation, yoga, or any form of movement. Any silly dancing or a round of very hearty laughter, the from-your-gut kind, can help alleviate stress.
5. Prioritize your social life
Perceived social isolation has been linked to impaired immunity and a whole host of other health issues. To combat loneliness, create and maintain meaningful social connections, stay in touch with loved ones, say yes to activities you enjoy, volunteer, or participate in book clubs or community groups. Find a church where you and your family can feel at home and cared for.
6. Consider supplements
Check with your health care practitioner before taking a new supplement. Best practice is to separate supplements and medications by two to four hours depending on what your health care practitioner advises. Since supplements may interfere with your absorption of a medication (giving you too much or too little of the drug, including OTC medication), knowing supplement and medication interactions is very important. For example, many supplements also thin blood and may be contraindicated for those taking blood-thinning medications like warfarin.
