How to Boost Your Immune System and Beat Sickness Bugs


Yearly, illness bugs sweep throughout nations like locusts, piercing our physique’s pure defenses and leaving us with runny noses, sore throats, fevers, and lots of different debilitating signs.

And whereas everybody hates getting sick, it’s particularly aggravating for us health people. It not solely knocks us out of our routines for days and even weeks, as soon as we’re higher, it takes nearly as lengthy to get again to the place we left off when it comes to efficiency.

That’s why I make the most of the varied methods given on this article to spice up my immune system and beat illness bugs, and whereas I nonetheless get a chilly a couple of times per 12 months, they’re very delicate and final only some days.

So, let’s begin with discussing what the immune system is and the way it works, after which we’ll get to learn how to strengthen it and stop and shortly overcome illness.

How the Immune System Works

The immune system is an amazingly complicated community of cells, tissues, and organs that defend the physique towards “assaults” by exterior invaders. Most of those invaders are tiny organisms like micro organism, parasites, and infection-causing fungi, and viruses, all of that are capable of flourish within the human physique.

The varieties of invaders on the market quantity within the tens of millions, and the immune system’s job is to acknowledge and maintain them out. Some inevitably sneak by the physique’s defenses, although, and the immune system hunts them down and wipes them out with particular varieties of fluids and cells.

For instance, check out the next picture:


Within the picture on the left, you possibly can see two giant micro organism that trigger gonorrhea, aspect by aspect. Within the picture on the precise, you possibly can see these micro organism “swallowed up” by a big immune cell generally known as a neutrophil, which engulfs and kills the invading micro organism.

The more healthy your immune system is, the sooner and extra powerfully it will possibly defeat invaders, thus stopping illness in lots of instances, and lowering severity and length in others. 

Train and the Immune System

Contemplating the truth that common train improves nearly each side of our well being, it’s no shock that it directly improves immune function.

It’s, nonetheless, doable to have an excessive amount of of a superb factor: too much exercise can actually impair the immune system, which is likely one of the symptoms of overtraining. Finally what’s “an excessive amount of train” varies from physique to physique, however my expertise working with hundreds of individuals has taught me this:

It’s tougher to overwhelm the immune system with train than you would possibly suppose. And that’s very true once you’re consuming loads of healthy foods and getting sufficient rest and recovery. That mentioned, I usually suggest that individuals restrict their complete weekly train to eight hours or much less, and that they embody sooner or later of no train in any respect every week.

Exercising When Sick

I completely perceive the need to train when sick. When you’ve established a superb train routine, you actually don’t like messing with it.

The truth is intense train is simply going to make the illness worse, although. Why? As a result of intense train temporarily depresses immune function, which provides the invaders extra time to wreak havoc in your physique.

That mentioned, animal research has proven that gentle train (20 to 30 minutes of sunshine jogging on a treadmill) carried out whereas contaminated with the influenza virus boosts immune perform and speeds restoration.

Comparable results have been seen in human studies as properly, which is why I like to recommend not more than Three periods of 20 to 30 minutes of sunshine cardio when sick (it is best to by no means get too winded to talk).

Smoking and the Immune System

Smoking is up there with alcoholism as one of the vital unhealthy habits you possibly can develop, and amongst its many liabilities is the suppression of the immune system.

Analysis has proven that smokers generally get sick more often than non-smokers and that people who smoke are much more likely to contract respiratory diseases than non-smokers. Moreover, cold and flu viruses make smokers sicker than non-smokers.

The reply, after all, is to give up smoking, and whereas I’ve by no means smoked, I might undoubtedly use this book to give up if I did–it’s a time-proven, extremely successfully instrument for quitting simply and completely.

Physique Weight and the Immune System

There are larger issues with being obese or overweight than the way you look: it’s extremely unhealthy, increasing the risk for all kinds of disease together with sort 2 diabetes, most cancers, reproductive issues, coronary heart illness, and extra.

Research has proven that one of many causes for that is the persistent systemic irritation that comes with being obese or overweight, which impairs immune perform, thus increasing the likelihood of infection and the duration of sickness.

The answer is clear, and whereas many individuals are made to consider that losing fat and building muscle is extremely arduous or sophisticated, it’s not. It doesn’t require that you simply reside within the fitness center…. It doesn’t require that you simply observe unusual, overly restrictive diets… and it doesn’t require that starve your self and even battle with starvation.

All wholesome weight reduction requires is wise meal planning that features loads of tasty, nutritious meals, and a proper exercise program that makes use of average quantities of weightlifting and cardiovascular train to burn energy, construct muscle, and keep well being.

Diet and the Immune System

The meals you eat have a significant affect on the competence of your immune system. Micronutrients similar to zinc, selenium, iron, copper, beta-carotene, nutritional vitamins A, D, C, and E all play important roles in keeping your immune system strong.









The much less wholesome, micronutrient-dense meals you eat, the extra seemingly you’re to develop deficiencies within the many vitamins and minerals your physique wants to keep up optimum well being and immune perform. This, in flip, impairs immune function.

Ideally, we’d get all the nutritional vitamins and minerals we want from the meals we eat, however that is simpler mentioned than completed.

Personally, I favor an easier strategy. I make sure that the vast majority of my energy come from nutrient-dense meals, like the next:

  • Avocados
  • Greens (chard, collard greens, kale, mustard greens, spinach)
  • Bell peppers
  • Brussels sprouts
  • Mushrooms
  • Baked potatoes
  • Candy potatoes
  • Berries
  • Low-fat yogurt
  • Eggs
  • Seeds (flax, pumpkin, sesame, and sunflower)
  • Beans (garbanzo, kidney, navy, pinto)
  • Lentils, peas
  • Almonds, cashews, peanuts
  • Barley, oats, quinoa, brown rice
  • Salmon, halibut, cod, scallops, shrimp, tuna
  • Lean beef, lamb, venison
  • Rooster, turkey

And I take a high-quality multivitamin complement day by day to make sure I don’t turn out to be poor in something necessary. Right here’s what I’m at present utilizing and liking:



Way of life and the Immune System

Whereas train falls below the banner of way of life, it deserved its personal part. On this part, I wish to talk about a number of different lifestyle-related components of immunity.

Persistent Stress Will increase Danger of Illness

Research has proven that whereas acute stress enhances immune perform (the great previous “struggle or flight” mechanism working for us), persistent stress suppresses it.

So, attempt to not sweat the little annoyances a lot, steer clear of unfavorable folks that attempt to maintain you down, keep away from overtraining within the fitness center, take a while for your self daily to relax out, and keep away from conflicts by making an attempt to deal with others the way in which you’d prefer to be handled, and also you’ll not solely be happier in life, however you’ll get sick much less usually.

Insufficient Sleep Will increase Danger of Illness

For generations, moms have been telling their youngsters to get sufficient sleep or they’ll get sick…and it turns on the market’s some reality in it.







Analysis has demonstrated that acute sleep deprivation acutely suppresses immune function, and the longer sleep is restricted, the more likely you are to get sick. And never solely chilly and flu sick, however coronary heart illness and diabetes sick as properly.

The underside line is, like smoking and over-consumption of alcohol, usually not getting sufficient sleep is extremely unhealthy and, over time, can contribute to every kind of illness and dysfunction. What’s enough sleep varies from individual to individual, although. Try my article on how to sleep better for extra data.

Have Extra Intercourse to Increase Your Immune System

You most likely don’t want a lot convincing to have extra intercourse, however right here’s one more reason:

Analysis has proven that regular sex boosts immune function, and thus helps your physique struggle off illness bugs just like the flu and different micro organism and viruses.

Particularly, the examine discovered that college-aged folks having intercourse a couple of times per week had larger ranges of immunoglobulin A (IgA), the physique’s first line of protection towards chilly viruses, than folks having intercourse much less or extra (bummer) steadily. Moreover, the examine additionally discovered that larger ranges of satisfaction and length in relationships had been related to larger ranges of IgA.

So, have extra intercourse, get pleasure from your relationship, and keep wholesome.

Dietary supplements That Increase the Immune System

Vitamin C

Vitamin C is present in excessive concentrations in immune cells and is shortly consumed throughout infections.

Research has proven that common consumption of vitamin C as much as about 1 gram per day helps scale back signs and shorten the length of respiratory tract infections just like the widespread chilly. Supplementation with vitamin C additionally helps reduce systemic inflammation and cortisol levels, which might additional enhance immune power.

This is the reason I complement with 1 gram per day, and right here’s the product I take:


Fish Oil

Because of its excessive quantities of omega-3 fatty acids, fish oil has a long list of health benefits, and a recently published study has uncovered one more:









Fish oil, which was as soon as believed to suppressed immune perform, really enhances it by bettering the perform of B cells, a kind of cell very important to the immune system’s defenses.

Not all fish oils are equal, nonetheless. The cheaper choices include an inferior, processed type of the oil (ethyl ester), which is much more resistant to the enzymatic process by which the physique breaks the oil down to be used. Not solely that, however the cheaper oils even have low ranges of omega-Three fatty acids, requiring that you simply take a number of handful of capsules daily to succeed in the recommended 3.5 to 4.5 grams of omega-3 fatty acids per day.

As an alternative, you need the pure trigclyeride type of fish oil, which is better absorbed by the body, and which has larger concentrations of omega-Three fatty acids. And that’s why I purchase and use this product:

Nordic Naturals Ultimate Omega fish oil.

Nordic Naturals is likely one of the most revered manufacturers of fish oil available on the market, and this particular product is a “double power” EPA/DHA system, with 650mg of EPA and 450 mg of DHA in every serving. Most different fish oils include half of that per serving.

Vitamin D

Vitamin D deficiency has been related to an elevated threat of creating all kinds of ailments, similar to osteoporosisheart diseasestrokesome cancerstype 1 diabetes, and multiple sclerosistuberculosis and even the flu.

Moreover, in accordance with research published by the Center for Disease Control in 2011, 8% of Individuals are vitamin D poor, and 25% are thought-about “in danger” of a deficiency. Different research published in 2010 confirmed that just about 70% of breast-fed infants had been vitamin D poor at one month, which might be significantly dangerous contemplating how necessary this vitamin is in general well being and improvement.

And whereas we will get vitamin D by going within the solar for about 15 to 25 minutes per day, few are capable of usually do this. As an alternative, we will simply take a day by day complement. How a lot ought to we be taking, although?

A committee of the U.S. Endocrine Society not too long ago convened to review the evidence, and concluded that 600-1,000 IU per day is enough for ages 1-18, and 1,500-2,000 IU per day is enough for ages 19+.

Right here’s the product I take advantage of:

Now Foods vitamin D-3.


Echinacea is a kind of flowering plant within the daisy household, and it has lengthy been used as an natural product to assist struggle colds and different widespread sicknesses.

Echinacea’s use as an immune booster has been controversial in scientific circles. There’s research showing it to be effective in each lowering the probability of getting sick and the length of illness, and there’s research demonstrating no such benefits. That mentioned, a number of medical trials which have didn’t show immune advantages have been criticized for utilizing inferior types of echinacea extracts and for utilizing dosages too small to do something.

Whereas I don’t take echinacea year-round, I do take about Three grams per day if I’m sick or in shut contact with sick folks (workplace or household). Right here’s what I take:



Zinc is a vital mineral that performs an important position in many various features of mobile metabolism, including immune function.

As zinc is crucial to the formation of cells used by the immune system to fight off invaders, making certain your consumption is enough is a vital a part of holding your immune system robust.

  3. Chorus from consuming or smoking for an hour, after which take a sip of it (5 – 10 ml) and swirl it round in your mouth for 10 seconds.
  4. Assess your zinc ranges as follows:
    1. Very Poor: If it tastes like plain water for all 10 seconds, you’re severely poor and may complement with about 150 mg of zinc per day to right, and retest after per week.
    2. Fairly Poor: If it first tastes like water after which, inside the ten seconds of the check, it tastes dry or metallic, this means a average deficiency. Complement with about 100 mg of zinc per day to right, and retest after per week.

    4. Ample: If the dry, metallic style is fast, robust, and unsightly, this means no deficiency is current. It’s seemingly that your eating regimen is offering adequate zinc. You possibly can retest each couple of weeks to make sure you haven’t developed a deficiency.

Should you do the above check and uncover you’re poor in zinc, I like to recommend you choose up some zinc gluconate and complement accordingly.


Should you discover and deal with a deficiency, you possibly can stop it from recurring by getting wherever from 15 – 150 mg of zinc per day, primarily based in your physique’s wants. You possibly can get hold of this by means of food or supplementation.

Aged garlic extract is especially efficient: research has proven that it reduces the severity and quantity of signs skilled whereas sick with a chilly or the flu.

Like echinacea, I don’t take aged garlic extract until I’m sick or round sick folks, and once I do, I take about 1 gram per day. Right here’s what I take advantage of:

It’s generally recommended that you simply take ginseng dietary supplements for lower than Three months at a time, so I embody it in my supplementation routine once I’m sick or round sick folks, and once I do, I take about 2 grams per day. You need the Asian (panax) type, and right here’s what I take:



Probiotics are good micro organism in your digestive tract, and analysis has proven that sure sorts not solely assist in digesting your meals, they also build up the immune system.

There’s an issue, although, as reported by the American Academy of Microbiology: lots of the probiotic merchandise available on the market are crap. In lots of instances, the micro organism are lifeless, and thus the merchandise are nugatory. That is very true within the case of merchandise that embody probiotics as a “bonus” (the processing of such merchandise kills the micro organism), in addition to low-cost merchandise that don’t should be refrigerated.

That’s why I follow NOW Meals, a extremely revered model that has undergone fairly a little bit of scrutiny through the years in the way in which of third get together testing and are available out unscathed. Right here’s the product I take advantage of, and I take one capsule per day throughout flu season or once I’m sick or round sick folks:
