How To Naturally Boost Your Immune System
With the cold winter months coming before us, it is now a good time to start thinking about how best to protect and reinforce our immune system for this winter, and to prevent any unnecessary sicknesses in the times of this pandemic.
As you will see, our immunity largely depends on external factors such as food, exercise, and lifestyle habits, meaning that it is well within our control to promote and maintain a healthy and strong immune system.
If you are interested in finding out how to take care of your immune system and how to prepare it for the colder months ahead of us, then read on.

ESSENTIAL MICRONUTRIENTS FOR IMMUNITY
VITAMIN A:
This vitamin has been linked with lower levels of inflammation in our body, which is directly linked with a healthier and stronger immune system. Not only that, but scientists believe that it has a role in the way our immune system responds to pathogens and how our white blood cells
Sources: Eggs, cod liver oil, orange and yellow colored vegetables and fruits, broccoli, spinach
VITAMIN C
It enhances white blood cell functioning and is needed for initializing cell death of old and unuseful cells. Apart from that it also protects against oxidative stress as it functions as an antioxidant, where lower levels of oxidative stress have been linked to lower incidences of chronic diseases.
Sources: Red bell pepper, citrus fruits, kiwis, broccoli, brussel sprouts, cabbage, spinach, green peas
VITAMIN D
Enhance the ability of white blood cells in our blood to fight pathogens and prevent our immune system from becoming too sensitive to the environment around us.
Sources: Salmon, sardines, egg yolks, mushrooms, sunshine (outside)
VITAMIN E:
Vitamin E is also an antioxidant and a crucial substance that plays a part in almost 200 biochemical reactions inside your body. It is well recognized as a contributing factor in the development and healthiness of your immune cells.
Sources: Sunflower seeds, almonds, sunflower oil, hazelnuts, olive oil, pine nuts, avocado, brazil nuts
ZINC:
Zinc is required for the development of white blood cells as well as the communication between your immune cells in combating inflammation inside your body.
Sources: Oysters, beef, seafood, legumes, pumpkin seeds, natural yogurt
SELENIUM:
A rather understated mineral, but selenium has more recently been shown to have a role in regulating inflammation and overall immunity in our body, where sufficient levels of this mineral have been linked with resulting in a less over-reactive immune systems and being able to treat chronic inflammation
Sources: Brazil nuts, seafood, and organ meats
5 PILLARS OF A STRONG & HEALTHY IMMUNE SYSTEM
NUTRITION
ADEQUATE SLEEP
MODERATE EXERCISE
HEALTHY LIFESTYLE HABITS
STRESS MANAGEMENT
1. NUTRITION
EATING WELL
Perhaps food is not the first factor you expected to see on how to maintain a healthy immune system, but it is a crucial and often an understated factor. Food has been used for millennia as not only a source of energy and time for socializing but as a way to treat, regress, and prevent diseases and sicknesses. Back then, medicine as we know it today was not available, so they had to take care of illnesses with what they had around, which was most of the time food in some shape or form.
The food we eat plays a crucial role in our health and consequently also our immune system, as whatever we input into our bodies, we absorb and use, so we have to be mindful of what we eat.
In terms of food that has been scientifically shown to have a positive effect on our immune system, you will see foods in their whole food (unprocessed) form, many of which are rich in micronutrients such as vitamin C and zinc, as well as foods naturally rich in antioxidants and probiotics. Here are some of the best foods you can eat to maintain a healthy immune system:
Red bell peppers
Spinach
Citrus fruits
Ginger
Natural yogurt
Almonds
Turmeric
Broccoli
Seafood and shellfish
Kiwi
Green tea
DRINKING ENOUGH WATER
Unsurprisingly, drinking water also affects our immune system just like at large it affects our overall health. Water plays many vital roles in our body, which is why it is so important to keep hydrated throughout the day. You can read more about the importance of water and why it is relevant to our health in this blog post: Why Drink Water
In short, water plays a few key roles in terms of our immunity. Firstly, keeping hydrated makes us less susceptible to germs and harmful bacteria as when our body is well hydrated it functions better all together, meaning that our immune system can fight off pathogens and viruses much more effectively.
Secondly, water is needed to allow our body to naturally detoxify itself and remove any unneeded metabolic waste products out of our system.
Thirdly, drinking enough water also makes sure to keep our blood healthy as our blood is predominantly made out of water so that our blood can effectively transport the needed nutrients and micronutrients to our body’s cells whenever they are needed. Linking with the previous point on food, if we want to be consuming foods with a high vitamin C content, it is additionally advised to drink water during your meal or your day, as vitamin C is a water-soluble vitamin, meaning that without water, our body will not be able to absorb it and thus make use of it.
CONSIDER SUPPLEMENTATION
Although I am a strong advocate for getting your nutrients straight from their raw source - food - as that brings along with it the most health benefits, it may also be worth considering supplementation in the case that you fall short of the recommended daily dosage of any of the important micronutrients for your immune system.
Supplements can come in the form of tablets that you take with a glass of water or tablets which you dissolve in water, but do your own research in terms of which nutrient you may be lacking and what dosage do you have to take, to cover your needs.
Regardless of whether it is our diet, our lifestyle our the weather outside (Vitamin D), we have to make sure that we are doing our best job of getting sufficient amounts of these micronutrients every day. Always try to first source your nutrients from food and then resort to supplements in the case that you may be deficient in any nutrient, especially if that nutrient is important for your immunity.
2. ADEQUATE SLEEP
More and more research is coming out reporting a strong link between poor sleep quality and a weaker immune system. The main reason behind this is that during sleep our body both produces and releases special immune proteins called cytokines, which are heavily responsible for controlling and fighting both inflation and infection in our body.
If we sleep less than what we should be or if our sleep is of poor quality, our body produces less of these cytokines, leading to a weaker immune system. Furthermore, sleep plays an important role in regulating our internal environment, where it also affects the efficacy of other immune cells.
In addition to this, sleep in general is very important for our health, as it performs a variety of different functions in our body. Inadequate sleep has also been correlated to a greater incidence of developing chronic diseases as well as greatly impacting our mental well being.

3. MODERATE EXERCISE
It has been found that doing moderate exercise every day not only improves our cardiovascular health, lowers blood pressure, and reduces our chances of developing chronic diseases, but it also positively contributes to the well being of our immune system. The reason behind this is still being researched since there are a lot of factors to take into consideration here.
One idea may be that doing exercise improves our blood circulation, which may help in expelling unwanted toxins and inflammatory molecules from our bodies. Better circulation also delivers more oxygen to our cells, which can directly impact their functioning as our cells need oxygen for respiration and for staying alive.
Since our breathing rate is faster during exercise, exercise may actually help clear up our lungs and airways, by flushing out harmful bacteria through having to breathe faster.
Lastly, since exercise has been effectively shown to decrease levels of stress in our body, that has also been linked with better immunity, as you will see below, stress has a direct impact on our immune system
4. HEALTHY LIFESTYLE HABITS
QUIT SMOKING
Smoking has been for a long time now labeled as a hazard for our health, including our immune system. Smoking and inhaling smoke has been linked with our body being less effective at fighting disease and inflammation, making us more susceptible to falling ill.
Furthermore, smoking distorts the balance of our immune system where it increases the chances of us developing autoimmune diseases (Diseases where our body will attack its own healthy tissues and cells). Overall smoking is not a healthy practice as it impacts a myriad of other aspects of our health and acts as a major carcinogen for our body. Abstaining from this practice is one of the best things you can do for your health.
KEEP ALCOHOL CONSUMPTION MODERATE
Excessive alcohol consumption has more recently been linked with a poorer immune system, whereby immunologists have observed that drinking too much alcohol, destroys different types of cells throughout our body, such as those in our respiratory pathways that are responsible for clearing up our airways of trapped dust particles and bacteria.
Furthermore, alcohol has also been shown to kill healthy normal gut bacteria, that otherwise have a positive impact on our health, but due to excessive alcohol consumption, their functioning is inhibited.
Apart from that, alcohol also interferes with our sleep where it has been shown that it impacts the REM part of our sleep cycle, and as we have seen previously, whatever impacts our sleep also impacts our immune system.
HYGIENIC PRACTICES
Keeping a good level of hygiene is important for general well being and preventing seriously harmful pathogens from entering our body.
This however does not mean that our environment should be excessively sterilized and sanitized, as our body needs to be exposed to a certain degree of uncleanliness for our immune system to stay active and also for it to not become over-reactive.
Generally, try and keep yourself clean and avoid having your hands in contact with your face, as our hands usually carry the most bacteria, but however do not go overboard with your sanitation practices, as that can also have an adverse effect.
5. STRESS MANAGEMENT
You might be surprised to hear this, but high levels of stress have been associated with a weaker immune system, which might be making you more susceptible to infections and illness.
A reason for why this may be happening is that when we are stressed, our body produces different stress hormones such as cortisol and corticosteroids, which have been shown to suppress the effectiveness of our immune system.
Stress impacts our body in more ways than you may initially think, ranging from slower digestion, headaches, higher blood pressure, raised heart rate, and raise blood cholesterol levels. All of these individual factors do not only contribute to a higher incidence of developing chronic disease, but also resulting in a weaker immune system.
Apart from this, people also use different coping methods to handling stress, such as excessive alcohol drinking, poor diet choices, sleeping less, or not taking time to exercise, all of which additionally add on top of the stress and worsen our immune system even more.
