How to Naturally Boost Your Immune System

Recently, we’ve all become a little more aware of our immune systems, with concerns as to how well our bodies would be able to fight off a virus, should we be exposed to it.

The good news is that, although you can’t guarantee how your body will react to any virus and only good hygiene and social distancing can protect you from developing COVID-19, you can give your body a fighting chance by ensuring your immune system is in tip-top condition at all times. Read on for some easy-to-implement tips as to how to boost your immune system, naturally.

It goes without saying that what you put in your body is crucial to the way it functions. A poor diet and sedentary lifestyle will leave your body struggling to defend itself, but by focusing on making small but significant dietary and lifestyle tweaks, you can strengthen its natural defences.

Whole foods

Reducing processed foods in your diet is a good place to start. By replacing ‘junk’ food with whole foods, you can strengthen the healthy bacteria in your gut, increase your antioxidant levels and elevate your intake of nutrients such as vitamin C. All these factors help your body work harder. This can feel daunting, so take small steps; perhaps swapping one meal a day for a more wholesome alternative.


Adequate sleep reduces the risk of contracting viruses such as the common cold because it strengthens your immune system. If you have difficulty sleeping, try limiting screen time and sticking to a rigid bedtime routine.

Limit sugar

Research has discovered that sugar contributes to obesity, and obesity increases the risk of of chronic health conditions, such as diabetes and heart disease which, in turn, weaken your immune system. Try reducing sugar a little at a time by halving the amount you have in drinks and on cereals and eating fresh fruit as an alternative to a sugar-laden snack.

Moderate exercise

Exercise may feel like a daunting prospect, but even a little will help. Moderate exercise, such as walking briskly or swimming is best for boosting your immune system, but, as with any lifestyle change, it’s more sustainable to start small. The good news is that research shows that spending time with trees increases immune function, so take a walk to your local park or woods to reap the benefits!
