While cold and flu viruses circulate all year long, they tend to survive better in cooler temperatures and lower humidity, and spread more easily among people who are spending more time indoors in close contact with others. These are the two biggest reasons we see an uptick in illnesses during the winter season.
While you feel completely normal, your immune system is working every hour of every day to keep you healthy, identifying threats and fighting them off before you ever feel a thing. But your immune system needs a few things to do that job well. Fortunately, you don’t need a medicine cabinet full of supplements or a complete lifestyle overhaul to support your immune system.
Continue reading to learn practical ways to strengthen your immune system this cold and flu season, and where to find the best family doctor in East Brunswick for when you aren’t feeling your best.
Five Evidence-Based Tips for Strengthening Your Immune System During Cold and Flu Season
You don't need a complete lifestyle overhaul to stay healthy this season. Often, the simplest habits make the biggest difference. Here are a few tips from the best family doctor in East Brunswick:
1. Eat Nutrient-Dense Foods
The food on your plate does more for your immune system than most people realize. Your body needs a balanced diet rich in leafy greens, fiber, vitamins, and minerals, along with adequate protein and healthy fats, to keep immune function running properly.
- Protein gets broken down into amino acids that your body reassembles into the proteins it needs to fight infection.
- Fiber feeds the healthy bacteria in your gut, which plays a bigger role in immunity than most people expect.
- Vitamin rich foods like fruits, leafy greens, and root vegetables, along with antioxidant-packed blueberries and green tea, are among the most well-supported options for immune health.
Additionally, cutting back on foods that don’t provide any nutrition can also help. A diet heavy in processed foods significantly reduces the intake of nutrients that support the immune system, because shelf-stabilized foods lose much of their nutritional value during processing. A simple rule of thumb: the more color on your plate, the broader your nutrient coverage.
2. Prioritize Sleep
If you had to pick one habit that does the most for your immune system, sleep would win. During sleep, your body produces proteins that help fight infection and inflammation. Chronic sleep deprivation reduces these protective proteins while raising stress hormones that suppress immune function. That's a double hit: less of what helps you fight illness and more of what makes you vulnerable to it.
Research finds that people who sleep fewer than six hours a night are up to four times more likely to catch the common cold compared to those who get seven or more hours. That gap is larger than what most supplements can come close to closing.
Here are some things to try if you’ve been struggling to get a full night’s rest:
- Keep a consistent bedtime and wake time, even on weekends, so your body can settle into a reliable rhythm
- Keep your bedroom cool and as dark as possible
- Cut off caffeine by early afternoon and put screens away at least 30 minutes before bed
3. Manage Stress
When stress stays elevated for a long period, the body produces more cortisol, which can suppress the immune system and make it harder to fight infections. The problem is that most people don't notice stress building until they're already run down. The good news is that the solution doesn't have to be big. Mindfulness meditation, deep breathing, and yoga have solid research behind them as stress-reduction tools, but you don't need a practice that takes an hour a day to see results. Even a ten-minute walk outside, a phone call with someone you trust, or twenty minutes away from your screen can bring cortisol levels down in a meaningful way.
4. Stay Active
You don't need an intense fitness routine to give your immune system a boost. Regular, moderate movement is what actually helps. The connection between exercise and immune system function is especially important during cold and flu season. Most adults benefit from about 30 minutes of aerobic exercise five days a week, and maintaining that kind of active lifestyle plays an important role in effective immune regulation. That can be anything from a brisk walk, a bike ride, a dance class, or a swim.
Movement improves circulation, lowers stress hormones, and helps immune cells travel through the body more efficiently, while also providing a natural energy lift during darker, colder months when motivation tends to drop. If you're just getting started or dealing with low energy this winter, begin with 10-minute sessions and build from there.
5. Practice Good Handwashing and Illness Prevention Habits
Handwashing is one of the most efficient ways to prevent bacteria and viruses from entering the body in the first place, because hands make contact with the mouth, eyes, and nose many times throughout the day without people realizing it.
- Wash with soap and warm water, vigorous rubbing for at least 20 seconds
- Always wash your hands after being in public spaces, after using the bathroom, and before eating
- Also wash your hands after blowing your nose or sneezing to help minimize the risk of spreading germs
Beyond handwashing, disinfecting the surfaces you touch often, like your phone screen, door handles, keyboard, and steering wheel, makes a real difference during peak season.
Additionally, getting the flu vaccine remains the most effective single step for protecting against influenza. Health experts across the board recommend getting vaccinated early in the season, particularly for older adults and people with chronic health conditions.
