Colds and flu season doesn’t have to knock you off your feet. While over-the-counter meds might offer quick relief, building a strong immune system is your best long-term defence. The good news? You don’t need to rely on harsh chemicals or complicated routines. By making a few simple, natural changes to your daily habits, you can give your body the tools it needs to fight off bugs before they take hold. Let’s explore how you can strengthen your immunity the natural way, so you stay healthier, longer.
Why do we get colds and flu during winter?
- We spend more time indoors.
When it’s cold, people stay inside where it’s warm. That means we’re closer to others, making it easier for viruses to spread from person to person.
- The air is drier.
Cold winter air (and indoor heaters) dry out your nose and throat. This makes it harder for your body to trap and fight off viruses.
- Less sunlight = less vitamin D.
We get less sun in winter, which can lower our vitamin D levels. Vitamin D helps keep the immune system strong, so lower levels can mean you’re more likely to get sick.
- Viruses survive better in the cold.
Cold, dry conditions help viruses like the flu stay active and infectious for longer.
What is the immune system?
Your immune system is your body’s natural defense team. It’s made up of cells, tissues, and organs that work together to protect you from germs like viruses, bacteria, and other harmful invaders.
How It Helps You Stay Healthy
When a virus or germ enters your body (like the flu), your immune system:
- Recognizes the invader as something that doesn’t belong.
- Attacks it using special cells (like white blood cells) to destroy it.
- Remembers it, so next time, it can respond faster and stronger.
A strong immune system doesn’t just help prevent you from getting sick, it can also lessen the severity and shorten the duration of illness if you do catch something.
Habits That Weaken Your Immune System
Sometimes, it’s not just about what you’re not doing—it’s also about what you are doing that could be harming your body’s natural defences. Here are a few common habits that can weaken your immune system:
- Poor diet: Eating lots of processed foods, sugar, and unhealthy fats can lead to inflammation and poor nutrient absorption.
- Chronic stress: Ongoing stress increases cortisol, which suppresses immune function over time.
- Lack of sleep: When you don’t rest enough, your body doesn’t get time to repair and restore immune cells.
- Inactive lifestyle: Not moving enough can slow down circulation, making it harder for immune cells to do their job.
- Smoking and excess alcohol: Both impair immune responses and damage the cells that protect you.
- Ignoring gut health: A poor diet or overuse of antibiotics can disturb the gut microbiome, which plays a big role in immunity.
By becoming aware of these habits, you can start replacing them with healthier choices—giving your immune system the best chance to protect you all year round.
How can I strengthen my immune system naturally?
- Eat Immune-Boosting Foods: The food you eat directly affects how well your immune system works. Just like a car needs the right fuel to run properly, your body needs the right nutrients to build and support strong immune defenses.
- Fruits & Veggies: Rich in vitamins C and A (e.g. citrus, berries, spinach, sweet potato).
- Garlic & Onion: Natural antimicrobials that help fight viruses.
- Ginger & Turmeric: Anti-inflammatory and antioxidant.
- Probiotics: Found in yogurt, kefir, sauerkraut – support gut health, which is key to immune function.
- Get Enough Vitamin D: Vitamin D plays a key role in keeping your immune system strong and balanced. It helps activate immune cells that fight off viruses and bacteria, and also helps control inflammation so your body doesn’t overreact.
- Spend time in the sun (15–30 mins a day).
- Supplement if needed, many people are deficient, especially in winter.
- Prioritize Quality Sleep: Sleep is when your body does most of its repair and recovery—including your immune system. While you sleep, your body produces and releases infection-fighting cells and proteins (like cytokines) that help detect and destroy viruses and bacteria.
- Aim for 7–9 hours of deep, restful sleep.
- Your body uses sleep to repair and strengthen your immune response.
- Reduce Stress: Chronic stress weakens the immune system by increasing cortisol, which lowers your body’s ability to fight off infections.
- Chronic stress weakens your immune system.
- Practice deep breathing, meditation, or even short nature walks to lower stress hormones.
- Stay Active: Regular movement boosts circulation, helping immune cells travel through the body more efficiently to detect and fight infections.
- Moderate, regular exercise improves circulation and immune cell activity.
- Avoid overtraining, which can have the opposite effect.
- Cut Back on Sugar and Alcohol: Too much sugar and alcohol can weaken immune cells and reduce your body’s ability to fight off germs.
- Excess sugar suppresses white blood cell function.
- Alcohol impairs sleep and depletes nutrients your body needs to fight infections.
- Stay Hydrated:
- Water helps your body flush out toxins and keeps mucous membranes moist (your first line of defense).
- Consider Natural Supplements: Certain natural supplements can provide extra support by strengthening immune function and filling in nutritional gaps.

Ingredients in Manna Immune Support
If you look at the ingredients below, you can see why this product is formulated for ultimate enhancement of the Immune system. We only use 3 ingredients in the product to get the highest effect from each individual ingredient…
Eucalyptus Extract (Flavonoids and Polyphenols)(1)
The Anti-Oxidant properties (ORAC Value) in the Flavonoids and Polyphenols from this natural Eucalyptus extract are even higher than grape seed extract.
The Anti-Viral and Anti-Inflammatory properties are also very high, assisting in the relief and fighting of inflammation and immune response diseases.
Cancer Bush (Sutherlandia frutescens)(2)
Sutherlandia is one of South Africa’s most potent immune boosters. It has been used for centuries to treat ‘flu and chronic wasting diseases such as tuberculosis and cancer (and, lately, anecdotes abound of its beneficial effect in HIV/AIDS infection). This herb should not be seen as curative, but as an additional support to the person suffering from disease.
Spirulina(3)
This superfood is something that no one can go without. The Spirulina in this product has been harvested from 100% pure natural fountain water from the Franschhoek valley – the purest form of Spirulina in the world.
Health benefits of Spirulina to boost the Immune System:
- High in Vitamin B-12 and B Complex
- Strengthens the immune system
Scientists discovered it not only stimulates the immune system, it actually enhances the body’s ability to generate new blood cells. Important parts of the immune system, bone marrow stem cells, macrophages, T-cells and natural killer cells, spleen and thymus glands – all show enhanced activity. Scientists observe it causes macrophages to increase in number, become activated and more effective in killing germs.
“This is the second winter in a row that I did not get a cold or flu due to using the Manna Immune Support. I start in March before the winter and use it until August by taking two tablets in the morning and two after supper. Previously I use to get a cold at least twice every year. I strongly recommend this product to boost your immune system during winters. “
