7 Ways to Strengthen Your Immune System Now

7 ways to strengthen your immune system

Optimising your immune system has perhaps never felt as critical as it does in 2021.

In 2020, we saw the emergence of the novel pathogen SARS-CoV-2, and the spread of its resulting disease, COVID-19. 

When it comes to bolstering the immune system, a lot of people just want a quick fix or magic pill, but unfortunately, there is no such thing.  

If that’s disappointing, there’s still some good news: the most scientifically sound approaches to keeping your immune system healthy are healthy habits that don’t require you to buy pills or eat strange foods.


1. Reduce your stress

Stress weakens your immune system.  Simple adjustments such as disconnecting from news sources, social media, and reducing your screen time and information ‘intake’ in general are good ways to reduce stress.

Opting for walks or exercise in nature and open spaces, taking time to connect with your family, friends and pets is also hugely beneficial to your nervous system and general wellbeing.

Practicing mindfulness, breath work and incorporating meditation into your daily routine also helps to soothe your nervous system and reduce your stress response.

2.  Move Your Body

Exercise is a simple way of boosting your defence system.  Just 30 mins a day of walking, cycling, swimming or stretching / yoga will make a huge difference to your health and immune system.


3. Get Good Quality Sleep

Deep sleep is when our body goes into detoxification, rest and repair mode.  Sleep supports the proteins and cells of your immune system to detect and destroy any foreign invaders your body might come into contact with, like the common cold.  So a good night’s sleep helps to strengthen your immune response and it is especially important to allow yourself time to rest and recover when you are not feeling well.

Some tips for a good night’s sleep:

Turn off devices and screens a good hour before bed.  Wind down with a bath or shower, a good book and if you can, practice a few minutes of mindful breathing and meditation to soothe the nervous system into the rest and digest state.

- Some gentle stretching or ‘Yin’ Yoga also does wonders for the body and mind setting you up for a blissful night’s sleep. 

-  Allow your organs to rest and digest comfortably whilst you sleep by abstaining from eating at least 3 hours before bedtime and eating light, nutritious and easily digestible foods for your evening meal.  

- Abstaining from alcohol also provides a better night’s sleep, helping you to awaken more easily and with more energy.

- And lastly, hydrate with a glass of water or cup of soothing herbal tea before bedtime - try peppermint to help with digestion or chamomile to help soothe you into sleep mode 30 to 60 minutes before hitting the hay.

4.  Eat Natural and Whole Foods

The simple rule here is prepare your own food as much as possible!  And use ingredients that are as close to their natural state as possible.  Avoid processed, convenience and fast foods and try to have at least 5 servings of fruit and vegetables a day.


5.  Boost Key Nutrients

There is no single food, diet, supplement, natural remedy or product on the supermarket shelf that will effectively ‘boost’ your immune system.  However, certain nutrients can alter the way in which the immune system functions, and the inclusion of these nutrients is therefore very important to optimise immune health:

  • Vitamin C: found in dark green leafy vegetables, and red and orange fruits and vegetables as well as kiwifruit.
  • Vitamin E: found in nuts, seeds, oils (canola, sunflower) and avocado 
  • Vitamin A: comes in two forms: 
  1. Retinol - found in milk, cheese & butter.
  2. Carotenoids - found in carrots, capscium, kumara, pumpkin, oranges, squash, corn, lemon and in darky green leafy vegetables (spinach and broccoli)
  • Selenium:found in nuts, egg, fish, steak, seeds and lentils
  • Zinc: found in oysters, chicken, grains, chickpeas, peanuts, cheese, and milk

6.  Optimise Your Microbiome

Reducing sugar, trans fats, processed foods and increasing natural fibre by eating wholegrains, fibrous fruits and vegetables help to balance and restore a healthy microbiome.

Adding fermented foods such as sauerkraut and kimchi to your meals or taking a good probiotic are also ways to improve your healthy gut bacteria.

Gut health is a huge topic and integral to your overall health and wellbeing.  So if you want to dive in further and learn more about how to optimise your microbiome, check out Dr Libby’s suggestions on Daily habits to help keep your gut healthy’.

4 Simple Tips for Choosing Safe Cleaning Products

We all need to be using safe cleaners, however not everything on the store shelf is created equally. Many products contain corrosive, toxic chemicals that might “clean” well but they certainly don’t do much to protect the health of your family. These toxic chemicals can leave residues, especially harmful on food surfaces, and contribute to indoor air pollution – or worse.

What is Toxic Body Burden and What Can We Do About It?

Simply put, this term describes the amount of toxins in your body that you are unable to get rid of.  What is left is called “toxic burden” or “toxic overload”.   Too many toxins in your body at once will overload your system, and can lead to increased inflammation and oxidative stress if you don't reduce your exposure.
