The leaves are turning, the mornings are crisp, and you are starting to hear coughs and sneezes in the checkout line. Cold and flu season is right around the corner. Now is the perfect time to boost your immune system.
Your immune system is your strongest ally this time of year. It works hard to keep germs out and to help you recover faster when they get in. A few simple habits can help it do that job well.
One honest note first. No single food, pill, or powder makes you immune to illness. Talk to your healthcare provider for advice that fits you. Then make these habits normal in your household.
Eat Foods That Support Immune Health
Food is the foundation. Experts recommend a varied diet built around fruits, vegetables, nuts, seeds, whole grains, and healthy fats like olive oil. Your body needs a steady supply of vitamins, minerals, and protein to build and repair immune cells.
Eat the rainbow. Colorful produce is packed with vitamins and plant compounds. fruits, vegetables, nuts, seeds, whole grains, Aim for several colors on your plate each day.
Look for polyphenols. These plant compounds help protect your body at the cellular level. Two well-known types are resveratrol and flavonoids. Research suggests they support the immune system. They may also benefit your brain, skin, gut, and heart.
You can find polyphenols in many tasty foods:
- Green tea and black tea
- Grapes and red grapes especially
- Berries, apples, and citrus fruits
- Dark chocolate and cocoa
- Onions, garlic, and leafy greens
- Extra virgin olive oil, nuts, and seeds
Don’t forget protein and zinc. Your body uses protein to make antibodies. Eggs, beans, lentils, fish, and poultry are good sources. Zinc also plays a role in immune cell function. Look for it in pumpkin seeds, chickpeas, and lean meats.
Feed your gut. Much of your immune activity happens in your digestive tract. Plain yogurt, kefir, and sauerkraut may support healthy gut bacteria. Fiber from whole grains and beans feeds those good bacteria.
Go easy on sugar and processed foods. They can crowd out the nutrient-rich foods your body needs.
Get Regular Exercise
Exercise is like a wonder drug. It can improve nearly every part of your health. Movement increases blood flow and may reduce long-term inflammation. It also helps immune cells travel through your body to guard against invaders. Some experts believe it may even help flush bacteria from your lungs and airways.
Plan on at least 150 minutes of moderate exercise each week. That is about thirty minutes, five days a week. A bike ride, a brisk walk, a yoga class, or an on-demand video workout all count. Very hard training without enough rest can leave you run down, so listen to your body.
Stay Hydrated
Water does more than quench your thirst. It helps your lymphatic system work well. This system carries the white blood cells that fight germs. Lymph fluid is mostly water, so staying hydrated helps keep it moving.
Water also keeps the membranes in your nose and mouth moist. Those membranes are a first line of defense. They trap germs before they travel deeper into your body. Dry membranes make that job harder and may raise your risk of infection.
Keep a water bottle within reach all day. Warm herbal tea and broth count too. If plain water bores you, add lemon, cucumber, or a few berries.
Practice Good Germ Hygiene
To stay healthy during peak season, go back to the advice your parents drilled into you. It still works.
- Wash your hands often with warm water and soap.
- Avoid touching your face when you are out and about.
- Keep your distance from people who have symptoms.
- Disinfect doorknobs and other shared surfaces when someone at home or work is sick.
If you feel sick, stay home when you can. You will recover faster, and you won’t share your germs.
Sleep More, Stress Less
Sleep is when your body repairs itself and keeps your immune response in balance. Chronic stress works against it. Most adults need seven to nine hours each night.
Don’t stress about the sleep you aren’t getting. Easy changes can help with both. Build your evening routine around calming activities instead of screens. Try yoga, meditation, or reading a good book. Even ten quiet minutes helps. Keep your bedroom cool and dark, and keep a regular bedtime.
Talk to Your Doctor About Vaccines and Vitamin D
Vaccination is one of the best ways to prepare for flu season. Ask your doctor or pharmacist which shots are right for you. Autumn is a common time to get them.
Many people also get less sunlight in fall and winter. Ask your doctor about a vitamin D blood test before you start a supplement. More is not always better.
Your Simple Pre-Season Checklist
- Fill your plate with colorful, whole foods.
- Move your body for 150 minutes a week.
- Drink water throughout the day.
- Wash your hands and skip the face touching.
- Wind down with a book instead of a screen.
- Ask your doctor about vaccines and vitamin D.
The Bottom Line
You can’t control every germ you meet. But you can give your body its best chance to fight back. Start with one or two habits this week. By the time cold and flu season arrives, your household will be ready.
