Table of Contents
Up to 80% of the immune system is in the gut, making it key for health and fighting off sickness1. Boosting your immunity might seem hard, but making simple changes in diet and lifestyle can help. This article will show you 10 ways to naturally strengthen your immune system and lower your risk of getting sick.
Key Takeaways
- The immune system is heavily dependent on gut health, with up to 80% located in the digestive tract.
- Vitamin C, vitamin E, zinc, and other nutrients play crucial roles in supporting immune function.
- Prioritizing sleep, exercise, and stress management can significantly enhance the body’s natural defenses.
- Limiting added sugars and following a balanced, whole-food-based diet support a robust immune system.
- Incorporating fermented foods, staying hydrated, and practicing good hygiene are also effective immune-boosting strategies.
Prioritize Sleep
Getting enough sleep is key to a strong immune system. Research shows that not enough sleep makes you more likely to get sick. On the other hand, enough rest boosts your body’s defenses2. Health care workers often struggle with sleep because their jobs are so demanding2.
Experts say you should aim for 7 hours of sleep each day. Some people need 8 hours or more to feel rested2. Kids in school should sleep for 9 hours or more, and teens need 8 to 10 hours3.
If you’re having trouble sleeping, make your bedroom dark, quiet, and cool2. Also, avoid drinking alcohol 3 hours before bedtime to keep your sleep quality good2.
To keep your body’s natural rhythm, spend time outside during the day. Try to sleep up to 10 hours on your days off2. Using caffeine and naps wisely can help you stay alert, especially during long work hours2. Bright light during night shifts can also help you stay awake2.
By focusing on quality sleep and healthy habits, you can boost your immune system and health.
“Sleep and immunity are closely linked. Inadequate sleep can increase your susceptibility to illnesses, while getting enough rest can strengthen your natural defenses.”
Eat More Whole Plant Foods
Eating more whole plant foods can boost your immune system naturally. Fruits, vegetables, nuts, seeds, and legumes are full of nutrients and antioxidants. These help strengthen your body against harmful pathogens4.
Antioxidants in these foods fight free radicals, which cause inflammation4. Chronic inflammation can lead to heart disease, Alzheimer’s, and some cancers.
Fiber in plant foods feeds the good bacteria in your gut. This is key for immune function4. A healthy gut microbiome keeps harmful microorganisms out, boosting your immunity4.
- Fruits and vegetables are rich in antioxidants that can help reduce inflammation and support immune health4.
- Nuts and seeds provide healthy fats, fiber, and vitamins and minerals for a strong immune system4.
- Legumes, like beans, lentils, and chickpeas, are great for plant-based protein, fiber, and complex carbs for immune fuel4.
“A diet rich in whole plant-based foods can be a powerful ally in supporting a healthy immune system.”
By adding more diverse whole plant foods to your diet, you give your body what it needs. This helps it fight off health threats45.
Increase Healthy Fats
Adding healthy fats to your diet can boost your immune system. Foods like olive oil and omega-3s are anti-inflammatory. They help your body fight off infections and diseases6.
Olive oil is full of monounsaturated fats. These fats lower the risk of heart disease and type 2 diabetes6. They also help your immune system fight off harmful germs and viruses7.
The Benefits of Omega-3s
Omega-3s, found in salmon, chia seeds, and walnuts, support your immune system6. Eating two or more servings of fatty fish a week can prevent heart disease in high-risk people7.
- Omega-3s are essential fats our bodies can’t make, so we need to eat them6.
- They reduce inflammation and improve blood cholesterol, boosting immune function7.
- Good sources include salmon, sardines, walnuts, flaxseeds, and chia seeds6.
Incorporate Fermented Foods
Fermented foods like yogurt, sauerkraut, and kefir are full of probiotics. These good bacteria help keep our gut and immune system healthy8. Eating a few servings of these foods each day can help kids digest better, fight constipation, and boost their immune system8.
Starting kids early with fermented foods can make them like less sweet foods later8. Kids often enjoy foods like ketchup, pickles, yogurt, kefir, cheese, tempeh, buttermilk, miso, and tofu8.
The Science Behind Fermented Foods
Fermented foods are a great source of live bacteria, like lactic acid bacteria. These bacteria help our gut and keep us healthy9. They also help our immune system fight off bad cells8.
These foods also have special compounds that are good for us9. The bacteria in fermentation make these compounds even better for our health9.
Many studies have shown the health benefits of fermented foods9. Scientists have looked into how these foods affect our gut and immune system. They’ve also studied how the bacteria in these foods work10.
Adding more fermented foods to your diet can help your family’s health. From yogurt to sauerkraut, these foods are tasty and full of good bacteria8.
Limit Added Sugars
Reducing your intake of added sugars and refined carbs can boost your immune system and health11. The 2015-2020 Dietary Guidelines suggest no more than 10% of daily calories from added sugars. This is about 200 calories or 12 teaspoons for a 2,000 calorie diet11. Yet, Americans average 270 calories of added sugars daily, which is about 17 teaspoons11.
Research shows that too much sugar and refined carbs can lead to obesity, harming your immune system1112. Studies found that obese people were twice as likely to get the flu after getting vaccinated compared to non-obese individuals11. Cutting down on added sugars can reduce inflammation and aid in weight management. This lowers the risk of chronic diseases like type 2 diabetes and heart disease, which weaken the immune system11.
To cut down on added sugars, watch out for hidden sources in processed foods, drinks, and condiments12. Almost half of America’s added sugars come from drinks like sodas and fruit juices11. A 20-ounce sports drink has 122 calories from added sugars11. A 12-ounce can of soda has 126 calories of added sugars11. Choosing water or unsweetened tea over sugary drinks can greatly reduce your sugar intake and support your immune system.
Limiting added sugars and refined carbs is key to a healthy lifestyle that boosts your immune system1112. By doing this, you can fight inflammation, keep a healthy weight, and strengthen your body’s defenses against illness and disease1112.

Stay Hydrated
Keeping your body hydrated is key to a strong immune system. Our bodies are made up of about two-thirds water16. Water helps control our body temperature, aids digestion, and supports many functions that help us fight off sickness.
Experts say we should drink about 9 cups of fluids a day if we’re women, and 13 cups if we’re men16. But, how much water you need can change based on your age, how active you are, and your health. Some diseases and medicines can also make you need more water16.
Dehydration can cause serious problems like confusion, fainting, and a fast heartbeat16. In extreme cases, it can even be dangerous and need medical help16. To avoid dehydration, drink water all day, not just when you’re thirsty17.
Water is the best drink for staying hydrated because it’s free of calories and doesn’t have added sugars or harmful ingredients17. Sports drinks with electrolytes are good for people who do intense exercise, especially in hot weather17.
Keeping your body hydrated is vital for your health and immune system. By drinking enough water all day, you help your body stay ready to fight off infections and sickness.
“Drink water, stay hydrated, and keep your immune system strong.” – Unknown
Manage Stress
Chronic stress can weaken your immune system, making it harder for your body to fight off infections18. It’s vital to find ways to reduce stress and anxiety. These can harm your health and well-being.
Exercise is a great way to manage stress18. It can help you sleep better, which is important for your body’s recovery18. People who exercise often feel less anxious and more positive about themselves18. Exercise also releases hormones that can block pain and make you feel good18.
What you eat also affects how you handle stress18. Eating well can boost your immune system and improve your mood18. Foods rich in antioxidants, like fruits and vegetables, can protect your cells from stress damage18. A balanced diet is key to fighting stress’s effects on your body and mind18.
Stress-Relieving Practices
There are more ways to manage stress and support your immune system. Yoga and meditation, which focus on slow movements and deep breathing, can reduce anxiety and stress18. Meditation has been shown to lower stress and improve sleep and mood18. Deep breathing can also help calm your nervous system18.
Talking to people face-to-face can release hormones that reduce stress19. Positive self-talk can lead to a longer life, less depression, and better health18. Laughing can boost your immune system and mood18. Cognitive behavioral therapy can help change negative thoughts and manage stress over time19.
By using these stress-relieving practices, you can support your immune system and stay healthy181920.

“Stress is the trash of modern life – we all generate it, but if you don’t dispose of it properly, it will pile up and overtake your life.” – Danzae Pace
Consider Supplements
While it might be tempting to take supplements, especially when we’re worried about our health, we should be careful21. Over half of Americans take dietary supplements every day or sometimes21. The most common ones are multivitamins, calcium, and vitamins B, C, and D21. But, there’s no scientific proof that they can fight or prevent COVID-1921.
Some supplements might boost your immune system22. Studies show that vitamin C, vitamin D, zinc, elderberry, and echinacea could help22. But, always talk to your doctor before starting any supplements. They can affect your medicines or cause side effects21.
The FDA doesn’t check the quality or effects of supplements21. But, groups like USP and NSF test them and give approval21. Also, some herbal products might have harmful drugs, so be careful21.
To make smart choices about supplements, check out the NIH’s resources21. They have fact sheets, a database, and an app called My Dietary Supplements (MyDS) to track what you take21. The best thing is to talk to your doctor about what supplements might be right for you21.
Exercise Moderately
Intense exercise can weaken your immune system, but moderate exercise boosts it23. Research shows that one session of moderate exercise can make vaccines work better in people with weak immune systems23. It also helps reduce inflammation and helps your immune cells grow back23.
Adults should aim for 150 minutes of moderate exercise each week23. This can be brisk walking, cycling, jogging, swimming, or light hiking23. The goal is to keep your heart rate up without getting too tired.
Calculating Your Target Heart Rate
To exercise at the right intensity, use the Karvonen formula23. It considers your maximum heart rate, resting heart rate, and how hard you want to work23. Aim for a heart rate between 50-70% of your maximum during moderate exercise24.
Another way to check your intensity is the “talk test”23. You should be able to talk without struggling to breathe during moderate exercise23.
Adding strength training 2-3 times a week also helps your immune system24. It improves joint flexibility, builds muscle, and strengthens bones24.
Regular, moderate exercise can greatly strengthen your immune system2324. It prepares your body to fight off sicknesses better2324.
Quit Unhealthy Habits
Keeping your immune system strong is key to good health. Smoking and drinking too much alcohol can hurt your immune system2526. About 70% of smokers want to quit25. Drug and alcohol users also struggle to stop25.
It’s tough to stop bad habits. Behaviors like overeating or too much social media can make your brain crave them25. But, with effort and the right plan, you can beat these habits and boost your immune system.
- Regular exercise of self-control can help strengthen willpower25.
- Starting new healthy habits, like exercise, can replace bad ones2527.
- Visualization and support from friends and family can help break bad habits25.
Quitting smoking and drinking less can really help your immune system26. Also, avoiding secondhand smoke and managing stress are important for a healthy immune response26.
By quitting bad habits, you can greatly improve your immune system and health. With determination and the right plan, you can overcome these habits and enjoy a stronger immune system.
| Habit | Impact on Immune System | Strategies for Quitting |
|---|---|---|
| Smoking | Weakens immune function, increases risk of respiratory infections26 | Seek support, use nicotine replacement therapy, identify triggers25 |
| Excessive Alcohol Consumption | Impairs immune cell function, increases susceptibility to infections26 | Limit alcohol intake, replace with healthy activities, seek professional help if needed25 |
| Overeating | Can lead to weight gain and other health issues that compromise immune function26 | Practice mindful eating, increase physical activity, seek support from friends and family2527 |
“The greatest weapon against stress is our ability to choose one thought over another.” – William James
Choosing to quit bad habits is a big step towards a stronger immune system and better health. Remember, staying consistent and persistent is crucial. With the right strategies, you can overcome these habits252627.
Stay Socially Connected
Keeping meaningful social connections is good for our health and immune system. It makes us feel loved and valued, which helps our mental health. This can lower stress levels28. Studies show strong social bonds help us live longer and healthier lives28.
Being part of a community can make us feel more connected. It builds trust and a sense of belonging28. Safe public spaces help us meet others and feel less isolated28.
Good social connections can also improve our eating habits and physical activity. They help us sleep better, which is key for a strong immune system28. When times get tough, friends and family offer emotional support and help with daily tasks28.
Research finds people with strong social bonds live up to 50% longer than those without29. They are less likely to get serious illnesses like heart disease and depression. They also tend to eat better, exercise more, and sleep better29.
Staying connected is a powerful way to boost your immune system and health.
“Nurturing our social connections is not just a nicety – it’s a necessity for our health and well-being.”
Practice Good Hygiene
Good hygiene is key to keeping your immune system strong and stopping diseases from spreading. Washing your hands often with soap and water is a top way to stay clean30. Sadly, 2 billion people lack basic hygiene services like handwashing facilities30. Washing your hands for 20 seconds before eating and after being in public can really help31.
Good personal hygiene also helps your immune system and keeps germs away. This includes showering with soap, trimming nails, and brushing and flossing your teeth31. It’s also important to wash your genital area gently with soap and water32.
Using hand sanitizer with at least 60% alcohol is good when you can’t wash your hands31. Washing your hands after touching dirty surfaces and before eating is key to stopping germs32.
By making hygiene a part of your daily life, you can keep your immune system strong and avoid getting sick32. Good hygiene is a big part of staying healthy32.
Good hygiene is more than just staying clean; it’s about stopping germs and keeping your immune system strong. By focusing on hygiene, you’re taking a big step to protect your health and others around you32.
“Proper hygiene is the first line of defense against infectious diseases. It’s a simple yet powerful way to safeguard your health and the health of your community.” – Dr. Jane Doe, epidemiologist
