As an author focusing on health and wellness topics, I’m always looking for ways to take better care of myself. And with cold and flu season approaching, boosting my immune system is top of mind. I wanted to share the natural tips I’ve found that help me stay healthy all season long.

Throughout this article, I’ll discuss easy, research-backed ways you can support your immune system using food, herbs, essential oils, and lifestyle habits. My goal is to summarize the most practical ideas in clear, everyday language so you can immediately put them into practice. After all, who couldn’t use an extra boost during this time of year?

1. Eat More Immune-Boosting Foods

What we eat makes a big difference for our immune system. Many studies demonstrate that nutrient-rich whole foods keep our defenses strong and resilient.

Some of the top foods to include are:

• Citrus fruits – High in immune-boosting vitamin C. Oranges, grapefruits, lemons, limes, and clementines are all great choices.
• Broccoli – Packed with vitamins A, C, and E along with antioxidants to fight infection.
• Garlic – Contains antimicrobial and antiviral properties that deactivate or destroy some viruses and bacteria.
• Ginger – Known for its anti-inflammatory effects, which help moderate immune response. Fresh ginger makes a healthy, flavorful tea.
• Yogurt – Provides probiotics or “good bacteria” that keep your gut and immune system working properly. Go for unsweetened varieties.

Try working one or more of these foods into your meals and snacks on a regular basis. For example, add lemon to your tea or water, top salads and stir fries with broccoli, or enjoyGreek yogurt with fruit for breakfast. Delicious and nutritious!

Here is an easy Citrus-Ginger Immune Booster Smoothie recipe to try:

Ingredients:
- 1 orange, peeled  
- 1/2 lemon, peeled
- 1 cup pineapple chunks
- 1 Tbsp fresh ginger, grated  
- 1 cup baby spinach
- 1 cup coconut water

Add all ingredients to a blender. Blend until smooth. Enjoy!

2. Stay Hydrated

Water supports nearly every function in our body, including immune response. Without adequate fluids, our defenses operate less efficiently and we become more prone to illness.

How much water should you drink? General guidelines recommend eight 8-ounce glasses daily as a minimum. However, your needs may vary based on body size, activity level, health issues, and climate. The easiest method is to drink water when you feel thirsty and make sure your urine is light yellow.

Plain water is best, but you can also consume fluids from fruit, vegetables, soups and teas. Limit sugary sodas and fruit juices which may provide excess sugar and calories without essential nutrients. Investing in a reusable water bottle makes drinking enough easy. Just be sure to wash it frequently!

Staying hydrated supports every body system, keeps skin clear, improves energy levels, promotes kidney function and aids in elimination of toxins. Don’t wait until you’re thirsty – sip all day long for better overall wellness.

3. Manage Stress Levels

While occasional short-term stress provides an immune boost, chronic stress weakens your defenses by raising inflammation and stress hormones like cortisol. High cortisol also impairs digestion, sleep quality and blood sugar regulation – further taxing the immune system.

Making lifestyle changes to reduce sources of stress makes a significant difference long-term. Top recommendations include:

• Set realistic daily priorities instead of overscheduling
• Build relaxing activities into each day like taking a bath, meditating or enjoying a hobby
• Spend time outdoors which is naturally restorative
• Learn basic affirmations to interrupt spiraling negative thoughts
• Maintain supportive social connections instead of isolation
• Identify and express feelings instead of internalizing them

Also beware of unhealthy coping habits like excessive alcohol, overeating sugary or processed foods, or scrolling endlessly on your phone. These provide short-term relief by raise other health issues.

Pay attention to early warning signs like irritability, changes in sleep or appetite, low energy and mood changes. Take action early on to prevent bigger issues down the road. Supporting overall mental health safeguards immunity as well.

4. Utilize Immune-Boosting Herbs and Spices

For centuries, traditional herbalists have drawn upon plants and spices to prevent illness and recover more quickly. Extensive research now backs up the wisdom of these natural healers.

Some of most widely used immune enhancers include:

• Echinacea – Shown to activate white blood cells and counteract inflammation. Often used short term to prevent or treat colds.
• Elderberry – Provides antioxidant anthocyanins along with antiviral properties. Available as syrups, gummies and capsules.
• Garlic – Contains allicin and other compounds demonstrating antibacterial and antiviral effects against some respiratory infections.
• Ginger – Has a long history of alleviating nausea, pain and inflammation in many cultures. Fresh or dried forms boost immunity.
• Reishi mushroom – An adaptogenic mushroom used in Chinese medicine to modulate immune response and increase resistance to infections. Available as supplements.
• Turmeric – The antioxidant curcumin provides anti-inflammatory, antibacterial and liver-protective benefits. Best absorbed paired with black pepper.

These herbs can be consumed as teas, used while cooking or taken as directed on supplement labels. Always check with your doctor about potential medication interactions or contraindications before using herbal products.

When using dried herbs and spices, choose organic products whenever possible to avoid pesticide residues. Store them airtight containers away from light and heat to preserve potency.

5. Get More Sleep

While it’s rarely mentioned, quality sleep has a hugely positive influence on effective immune function. During deep phases of sleep, our body produces proteins like cytokines that target infection and inflammation. Skimping on sleep reduces their activity.

How much sleep do we need? Recommendations range between 7-9 hours per night for adults. Determine your own optimal amount and stick to a consistent schedule. Here are some tips to improve sleep quality:

• Establish a relaxing pre-bed routine listening to calming music, stretching or taking a bath
• Turn off electronic devices 1-2 hours before bedtime
• Make sure your sleep environment is cool, quiet and comfortable
• Invest in supportive pillows and a comfortable mattress
• Avoid stimulants like caffeine, alcohol and heavy meals right before bed
• Consider supplements like magnesium, glycine, melatonin or CBD under your doctor’s supervision

If you regularly feel tired waking up, have difficulty falling asleep or experience frequent nighttime awakenings, discuss options with your physician. Disordered sleep interferes with immunity, metabolism, cognition and mood regulation. Making it a priority has widespread benefits.

Supporting our body’s defenses is especially vital during cold and flu season. The great news? Achieving an immune boost is much more practical than you think.
