How to Strengthen Your Immune System Naturally This Autumn

BY EMILIE RICHARDSON-DUPUIS

This blog is an extract from ‘A Better You’ March 2025 edition. 

As the weather cools down, so does our body’s natural defence system. Autumn brings not only colourful leaves and cosy vibes but also a wave of seasonal illnesses like colds, flu, and other respiratory infections. The good news? You can take proactive steps to boost your immunity and keep yourself feeling your best.

At Independent Pharmacies of Australia, we care about your well-being and want to help you stay healthy all season long. Here’s how you can strengthen your immune system and fight off infections more effectively.

1. Prioritise Nutrition for a Stronger Immune System

Your immune system relies on essential nutrients to function at its best. Eating a balanced diet full of vitamins and minerals ensures your body is ready to defend itself against seasonal illnesses. Some powerhouse foods include:

• Garlic – Packed with sulphur compounds that have immune-boosting properties.
• Red capsicum – Contains more vitamin C than an orange, supporting immune function.
• Kiwi fruit – A great source of vitamin C to help shorten the duration of colds.
• Blueberries – Rich in antioxidants that fight off harmful free radicals.
• Salmon – High in omega-3 fatty acids, which help reduce inflammation.
• Yoghurt – A natural source of probiotics to support gut health and immunity.

If your diet is lacking certain nutrients, consider adding immune-boosting supplements like Vitamin C, Vitamin D, and Zinc to fill the gap. Your local IPA pharmacy can help you find the right ones for your needs.

2. Stay Active to Boost Immunity Naturally

Regular physical activity does more than keep you fit—it also enhances immune response! Exercise increases circulation, allowing immune cells to detect and combat infections more efficiently. Whether it’s a brisk walk, yoga, or a full-body workout, moving your body daily is essential.

3. Improve Your Sleep for Better Immune Function

Did you know that people who get less than 7 hours of sleep per night are up to three times more likely to catch a cold? During sleep, our body repairs itself, builds immune defences, and produces essential antibodies. To improve sleep quality:

• Aim for at least 7-9 hours of rest per night.
• Avoid screens before bed to regulate melatonin levels.
• Try magnesium-based sleep supports to help with relaxation.

4. Reduce Stress to Prevent Weakened Immunity

Chronic stress weakens the immune system, making you more susceptible to illness. Try incorporating mindfulness techniques like:

• Meditation or deep breathing exercises
• Spending time in nature
• Gentle movement activities like yoga or tai chi
• Talking to a pharmacist about stress-supporting supplements

5. Maintain Good Hygiene to Prevent Infections

Practising good hygiene can reduce your risk of catching colds and flu. Some simple habits include:

• Washing your hands frequently for at least 20 seconds
• Avoiding touching your face, especially eyes, nose, and mouth
• Disinfecting commonly used surfaces like phones, keyboards, and door handles

6. Take the Right Immune-Boosting Supplements

If you’re struggling to meet your nutritional needs through diet alone, supplements can provide an extra layer of protection. Popular immune-boosting supplements include:

• Vitamin D – Supports immune function, especially during colder months when sun exposure is limited.
• Zinc – Helps shorten the duration of colds and supports overall immunity.
• Probiotics – Strengthen gut health, which plays a crucial role in immune defence.
• Glutathione – A powerful antioxidant that helps the body fight off infection.

Common Myths About Immunity

Myth 1: Taking extra vitamin C will prevent colds.

Truth 1: While vitamin C supports immune health, excess amounts don’t necessarily prevent illness. However, taking the right amount daily can help reduce the duration and severity of colds.

Myth 2: Cold weather directly makes you sick.

Truth 2: Cold temperatures weaken your nasal defences, making it easier for viruses to invade. Spending more time indoors in close contact with others also increases exposure to germs.

Myth 3: Antibiotics can help fight colds and flu.

Truth 3: Most colds and flu are caused by viruses, which antibiotics cannot treat. Instead, focus on immune-boosting habits and over-the-counter remedies for symptom relief.
