Strong Immune System:
Four Essential Habits

Catching a simple cold can have a major impact on your everyday activities

Revised May 11,,2025

It usually starts quietly, a faint scratch in your throat or a mild stuffiness in your nose. At first, you might shrug it off as dust or a passing allergy, intent on pushing through your day. But as the hours go by, that discomfort grows. By the next morning, you wake up feeling as if you’ve been blindsided: your head is heavy, your body aches, and it’s clear you’re sick.

This abrupt shift from feeling fine to being unwell is always inconvenient, and never more so than in recent times, when even a mild cold can derail your plans and routines. For many, especially men juggling work and family, the goal is to minimize these disruptions as much as possible.

View your immune system as a vital defence mechanism, akin to a castle gate, that requires constant care and reinforcement to function optimally.

There’s no magic bullet to guarantee you’ll never get sick. Instead, it makes sense to treat your immune system as you would any essential piece of equipment: it needs regular attention and maintenance to do its job well.

Supporting your immunity isn’t complicated, but it does require consistency. Regular physical activity, a diet rich in nutrients, enough sleep, and effective stress management all help keep your body’s defences in good shape. Simple habits-like washing your hands often and steering clear of people who are ill-can also cut down your risk of catching something.

Just as important is knowing when to slow down. If you notice the early signs of illness, don’t ignore them. Giving yourself time to rest at the first warning can keep a minor issue from becoming something more serious. Taking care of your health is about staying effective, resilient, and able to handle whatever comes your way.

Doctors often recommend diet and exercise as a panacea for all your bodily troubles. They aren’t wrong. Multiple studies show in clear terms that exercise helps support a healthy immune system.

4 best practices for supporting a healthy immune system

1. Move Your Body Regularly
Consistent physical activity is one of the most effective ways to keep your immune system in top shape. Exercise helps regulate inflammation, supports circulation, and improves overall health of which contributes to your body’s ability to fend off illness. Whether it’s a brisk walk, cycling, or your favourite sport, aim for some form of movement most days of the week.

2. Eat for Immunity
A balanced, nutrient-rich diet is fundamental for immune health. Focus on whole foods like colourful fruits and vegetables, lean proteins, whole grains, and healthy fats. These foods provide essential vitamins and minerals-such as vitamin C, vitamin D, zinc, and iron-that help your body maintain strong defences. Including fermented foods and fibre-rich options can also support a healthy gut, which plays a key role in immunity.

3. Add Functional Foods
Incorporating functional foods into your routine can offer extra support. Chaga mushroom, for example, is packed with antioxidants and nutrients that help your body’s natural defences. Try adding Chaga powder to your morning coffee or tea for an easy boost. While it’s not a cure-all, it’s a simple way to give your immune system a little extra help.

4. Moderate Alcohol and Manage Stress
Too much alcohol can weaken your immune response, so it’s wise to keep consumption in check. Equally important is managing stress, as chronic tension can make you more susceptible to getting sick. Take time to unwind, practice deep breathing, or enjoy activities that help you relax. These simple habits can make a big difference in how your body handles everyday challenges.

While you can’t guarantee you’ll never get sick, these four practices can help strengthen your body’s natural defences and keep you feeling your best.
