5 Ways to support immune resilience and improve immune tolerance.
Click here if you missed my previous blog about immune tolerance and immune resilience. And where we spoke about how important it is to strengthen immune tolerance (when it is low) in order to support immune resilience, which in turn promotes a healthy, well-functioning immune system.
Below are the five lifestyle strategies I mentioned in my previous blog, that we need to follow to strengthen immune system health. And to make your life and heart full again. To make you healthy and strong. Here’s to a happy, healthy life. Of course, there are other strategies you can do as well, but these are your starters.
- Good sleep
- Proper diet and nutrition
- Physical activity at appropriate levels
One of the most neglected and misunderstood strategies to improve immune function, immune resilience and to avoid infections is good sleep. Certain immune system cells (natural killer cells and T-cells) that are used to fight infection are boosted and activated when we sleep. When we sleep the body repairs itself and we are at peace. When we wake up feeling refreshed and ready to start the day, it’s a sign that we have had adequate sleep. When we are grumpy and bumpy, groggy and cranky, that’s a sure sign we didn’t get enough sleep. The day ahead will be long. Adequate sleep is fundamental to a well-working immune system and immune resilience.
Go to bed early. Try to sleep at least 7 hours a night. It is well known that people who sleep less than 7 hours are more prone to heart attack. And 90 minutes before bedtime, turn off all devices and televisions. Let your mind breath…and relax. I know it’s easy to say go to bed early when all you want to do is watch some television or stay on your computer because you feel as if your day has been all work and no play. It seems unfair. But start off by doing it a few nights a week, try reading a book in bed for ten minutes to relax and wind down. You’ll soon see that you’ll get into the habit of it, and start feeling much better.
Remember that there is not a single tissue within the human body and not one process within the brain that is not enhanced with adequate sleep (minimum 7hrs per night), or in the other case, impaired without enough sleep (less than 6hrs per night).
Proper Diet and Nutrition
What is nutrition, is it simply food that fills us up without giving us any health benefits, or is it food that is overflowing with vitamins, minerals, healthy fats, etc, that helps us grow, develop, renew, and stay healthy? You guessed it, it’s the latter.
If you look the word nutrition up in the oxford dictionary, it is the “process by which living things (including humans ) 🙂 receive the food necessary for them to grow and be healthy.” Without good nutrition we cannot possibly be healthy and we cannot possibly have a robust immune system.
This, I believe, is what most people in today’s world don’t understand. The foods we eat build us up or tear us down. They build our immune system and push hormone production – hormones, in turn, support a healthy and robust immune system and really improve our immune surveillance…killer cells at work!
So what should we do? Firstly, we need to cut out processed sugars, and concentrated sugars from your diet. That would include concentrated fruit juices, sweets, boiled sugar sweets, candy, etc. Anything that has a high amount of concentrated sugar in it needs to disappear from your diet. Plus they are empty calories that don’t provide you with any nutrition, at all!
We need to eat lots of colourful and varied fruit and vegetables which are high in flavonoid antioxidants, which really help our overall immune system strength. Another major helper is to diversify our microbiome. In other words, we want to have as many different healthy bacterial species in our gut. A healthy gut is essential for a healthy immune system. In fact, believe it or not, approximately 80% of our immune system is found in the gut. Eat multiple kinds of vegetables, but try to change the vegetable you eat. Don’t eat the same fruit and vegetable all the time…change them, this way you will really improve your immune resistance, by improving your gut microbiome.
Last but not least cut out inflammatory foods. Avoid such things as fried foods, processed foods, high floury carbohydrates (eg pasta, breads, pizzas), which cause insulin surges, make you tired (it’s the insulin surge that makes you tired), and they also deplete antioxidant reserves.
Also, avoid partially hydrogenated fats which deplete our antioxidant reserves – they usually come in packets or boxes. Read the labels on the foods you buy.
Hydration…what is hydration? Again, in the Oxford dictionary hydration means, “The process of making something/somebody take in and hold water.” Water is the key word!. Drink lots of water throughout the day…drinking tea, coffee and alcohol can actually worsen the ‘hydration situation’ as these beverages act as diuretics, so we basically become dehydrated just from that. Please drink water and avoid sugary drinks. Another key to building immune resilience is to stay hydrated all the time. Don’t let yourself get thirsty.
When we are dehydrated the immune system goes into default, and we become more prone to infections. The immune system dysregulates and, interaction and communication (yes our immune system communicates…it talks to our body 🙂 ), and immune signalling becomes compromised. In other words, when we are dehydrated the immune system becomes less efficient. Another thing, dehydration impacts blood volume and can cause miscommunication (yes our body is talking again) between the lymphatic system and the immune system.
If you have an infection or feel you are about to get one, you definitely need to stay hydrated and drink (water!) all the time, as this helps clear the infection quicker.
Of course, you need to cut down on salt intake if you want to stay hydrated. High salt intake makes you urinate more often to try and get rid of the sodium and regulate osmotic pressure.
Physical activity at appropriate levels
Although this might sound strange the immune system communicates throughout the whole body – it has to, to enable us to have optimal immune function, and optimal immune resilience. So, throughout our body and throughout the trillions of cells we have in the body, we have different types of immune cells, from macrophage to antigen-presenting cells. What these cells do is test and sample whatever is coming into the immune system…so when a pathogen, viral, bacterial or other microorganism that causes disease, comes in, they check it out by sending an immune messenger. When a pathogen is detected they (immune cells) let the immune system know that it now needs to manufacture antibodies to protect it from this pathogen. T cells now need to switch on and our natural killer cells need to attack and deal with this infection. To achieve the best immune response this message has to reach the whole body as quickly as possible.
To quicken this process movement of any kind is important…but how much movement, when and how?
Movement promotes better blood flow, circulation, and lymphatic exchange of fluids. When you increase your heart rate, the blood flow and circulation enhances and when you pump those weights, and release and contract, it helps the lymphatic system to work more efficiently, and move fluids throughout the body at a greater speed. If you want to improve, support and/or build overall immune function, it is critical that you do some kind of movement/motion. However, the question is how much?
If you are healthy and have no immune challenges, strenuous exercise is fine, and can actually help release opioids, which have an incredible impact on immune cells like T cells, natural killer cells, and B cells, which of course, will strengthen immune system function and make it much more able to respond to any type of pathogen appropriately.
Instead, if you have an infection and are fatigued it’s best to slow down. Take it easy. High, intense exercise burns up antioxidants and reserves, which will really dampen our immune system. If you are not feeling too good or getting sick a brisk walk is just as good, it’s important not to fatigue yourself. Even a slow walk will activate your lymphatics and immune system function.
So, the key thing here is…
Any kind of movement, whether it’s high intensity or a gentle walk in the park, are critical to vascular dynamics (blood flow and exchange), to help push immune messengers throughout our body. If you want to improve your immune resilience and support tolerance, exercise, movement and motion are critical factors.
Emotions (Laughing and crying)
Really? Yes, really. These emotions can greatly impact immune resilience which help us to fight off infections and be less susceptible to infections that are going around.
Laughing actually triggers a release of opioids, that is of course, why we feel so relaxed and happy after a good laugh. As mentioned previously, opioids greatly impact immune system function by activating key cells such as T cells, natural killer cells and regulatory T cells that help the immune system to be more efficient in dealing with any type of pathogen. So, remember to laugh a lot and watch comedy films rather than tragedy. Laughing can have a profound impact on the immune system. ‘Be Happy – Laugh More – Stay Healthy’.
So what about crying? Hmm! Crying, believe it or not, this also helps us release opioids. For instance, in a critical situation or a crisis many of us cry. If you think about it we feel better after we’ve cried…it seems to relieve us somehow. When we start to cry opioids are released to act as a safeguard, and help dampen stress. In short, they help protect us from dealing with the stressor, which impacts the immune system.
So even crying significantly impacts the immune system by way of opioid release. Think about this next time you want to cry…just cry…and Be Happy!
I know we are all resistant to change, and yes, old habits die hard. But it’s your health we are talking about…it’s your life and the quality of it, no one else’s. Try these changes and see how it can change your life and your health. And if it helps to motivate you…these changes may even help you lose weight.
However, remember rebuilding a strong immune system doesn’t happen overnight, it takes time. You need to be consistent…you need to stick with it. Make yourself a New Years resolution, even if it’s not New Year…who needs New Year to make a new resolution? Start now and your summer will be off to a super start. Remember, the longer you leave your immune system to breakdown the longer it will take to repair.
