Our world is full of viruses and bacteria. The only way to avoid them entirely is to live in a sterile bubble. But who wants to do that? A better and more realistic solution: Boost your immune system, so your body can protect itself against germs that could make you sick.

The best way to boost your immunity is to get recommended vaccines. That includes flu and COVID-19 shots as well as the pneumonia vaccine.* Beyond that, it’s all about focusing on everyday things that can help keep your immune system thriving.

With cold and flu season here, now is the perfect time to make sure your daily habits are keeping you healthy and strong. Our fun five-step immune-boost challenge can help.

Here’s how it works. Below are five simple habits proven to help protect you against illness. Pick a day to begin the challenge. On day 1, try a new tip, like taking time to decompress. On day 2, add a second tip to your daily routine. Then keep going until you hit day 5.

At the end of the challenge, you’ll have five new habits that can help keep you healthy this fall, winter and beyond. Plus, they’ll support your immune system’s healing powers if you do catch a bug. Let’s begin.

Need a nurse?

1: Wash your hands the right way

This is really your first line of defense. Washing your hands regularly and thoroughly lowers the number of germs your body must fight off. Here’s when it’s most important to scrub up:

• Before and after preparing food or eating.
• Before and after being in a public place or touching things that lots of other people have touched (think: shopping carts, anddoor handles, and gas pumps and the like).
• After using the bathroom, caring for someone who’s sick, or blowing your nose, or coughing or handling garbage.

But don’t rush the process of washing your hands or you won’t do much good. The best way to wash your hands free of the most germs is to:

• First, wet them with clean running water.
• Then, lather them with soap by rubbing them together for at least 20 seconds. Be sure to lather with soap for at least 20 seconds.
• Rinse your hands well under clean water. 
• Dry them with a clean towel.

You also should keep a small supply of alcohol-based hand sanitizer close by.

A registered nurse is just a phone call away. Call our 24/7 Nurse Line at 1-855-493-7019 (TTY: 711) to speak with a nurse, 24 hours a day, 7 days a week. If it’s an emergency, dial 911.

2: Eat different fruits and veggies

The more colorful the fruits and vegetables you eat, the greater variety of nutrients you get. For example, you’ll get plenty of vitamin A in cantaloupe, sweet potatoes, spinach and red peppers. Vitamin A plays a key role in the growth and function of immune cells that fight off viruses.* And vitamin C — found in oranges, strawberries, broccoli and bell peppers — helps heal wounds and repair tissues all over the body. It may also help shorten the length of a cold by up to 1½ days, according to research.*

To get a jump on having brightly colored produce at every meal, try this for breakfast. Have a smoothie made with a frozen banana, blueberries, strawberries, spinach and almond milk.

3: Take a walk

Exercise can boost your immunity. Try to regularly get up to 45 minutes of moderate-intensity exercise to strengthen your body’s natural defenses. But don’t push your body too hard. That’s especially true for older adults and people who have a chronic condition such as diabetes or heart disease.*

So what is moderate exercise? Here are some things to try:*

• Brisk walking
• Biking
• Swimming laps
• Doing water aerobics
• Walking stairs
• Washing your car
• Gardening
• Raking leaves
• Dancing

4: Make sleep a priority

Too often, sleep takes a back seat to everything else in life that we need to do. And sometimes, worrying about those to-dos keeps us up at night. But, lost sleep takes a toll on the immune system. Too little sleep can increase your risk of infection and of developing conditions like heart disease.*

For today’s immune-boosting challenge, focus on putting sleep first. Ditch the late-night emails and chores. Turn off electronic devices such as your TV and smartphone at least an hour before bedtime. (The light from screens can keep you up.) And go to bed at a reasonable hour — a time that lets you get between seven and nine hours of sleep.

5: Take time to decompress

A little stress is normal. In fact, it can even ramp up your immune system and get it ready for a fight. But stress that goes on without relief can weaken your immune system. So try to find a little time every day to lower your stress levels.

Looking for some new ways to ease stress? Studies show mind-body therapies such as meditation, yoga, tai chi or qi gong can help improve coping, quality of life and well-being. Doing mind-body therapies regularly can even lower chronic inflammation. You can start by doing an online yoga video — there are options for all levels. Or download a meditation app on your smartphone.
