Anyone who suffers from hayfever will be as qualified as possible to attest to having a healthy and robust immune system. If you’ve got a seasonal allergy to the pollen of plants and grass, you’ll be well aware of your immune system going to work. Of course it’s not pleasant as you sneeze heartily and repeatedly and your eyes water incessantly, but it’s still good to know what your body is guarded against invaders and will dispatch histamines at a moment’s notice when a transgressor is detected.
Rather a shame that those pollen particles are a false alarm, but the immune system’s taking no chances!
For the rest of us, you’re probably not going to be aware every time you’ve got neutrophils on the march taking on bacteria, viruses, and the like but they go into action pretty darn often. Having a healthy immune system is very important for every human, and there’s natural ways you can improve the function of your immune system. Let’s have a look at them.
While there are no scientifically proven direct links between lifestyle and enhanced immune function, there’s plenty of evidence suggesting that making the following diet / lifestyle choices can help you have improved immunity, with the diet changes being particularly highly recommended by Sherri Danrin, a naturopathic doctor specializing in immunology and a regular contributor at YesWellness.
1. Eat A Diet High In Fruits, Vegetables, and Whole Grains, Plus Low In Saturated Fat
A very telling fact is that scientists have long determined that people who live in poverty and are malnourished as a result are more vulnerable to infectious diseases. This increased susceptibility is a result of micronutrient deficiencies, and in particular not getting enough zinc, selenium, iron, copper, folic acid, and vitamins A, C, B6, and Vitamin E. If you have reason to believe you’re deficient in any of these vitamins (click here for an easy quick-reference chart for vitamin deficiency syndromes) you can address them via dietary sources or quality supplements.
2. Exercise Regularly
Getting regular vigorous exercise – which means getting your heart rate up and breaking a sweat – is so beneficial for improving cardiovascular health, lowering blood pressure, controlling body weight AND supercharging your immune system to defend against viruses and disease. A large part of this is due to the fact that it promotes improved blood circulation, which allows cells and the different substance components of the immune system to move through the body freely and complete their job with maximum efficiency.
Important note; do not push yourself too hard when aiming to exercise vigorously. Know your limits of exertion, and if you need to take a break then take one. If you ever feel faint or can’t handle the strain, stop immediately.
3. Maintain A Healthy Body Weight
This point is added here immediately following exercise because one promotes the other, and they’re both helpful ways to improve your immune system naturally. And yes, that’s in large part because your circulation will be much improved when your hearts’ not working nearly as hard to pump blood throughout your body as it was before you lost body weight.
4. Control Blood Pressure
The important thing to understand here is that there is a relationship between prolonged stress and high blood pressure (hypertension), which in turn limits your immune system’s ability to product T-cells, which it uses to fight infections. Maintaining a low blood pressure will prevent your adrenal glands from being hyper stimulated and producing too much adrenaline and noradrenaline, which leads to a rather vicious cycle where the weakened immune system promotes more stress, which promotes more hypertension, which promotes further weakening of the immune system.
You get the idea, keeping your blood pressure at healthy levels and regulated is highly advisable here.
5. Get Sufficient Quality Sleep
By getting sufficient AND quality sleep, we mean a) getting enough of it (most people need 7 hours a night) and b), making sure you go through all of the 4 stages of sleep. As regards the second point there, the importance of getting through all of these stages is important as the N3 (3rd) stage is where you get your deepest and most restorative sleep and cellular energy is provided to the different systems of the body, including the immune system.
In order to establish a good circadian rhythm and get the best and most thorough sleep, try to establish consistency with the time you go to bed and wake up each day. Sleeping in on the weekends or days off may be appealing, but it’s best not to.
6. Drink Alcohol In Moderation and Don’t Smoke
This one will likely be fairly self-explanatory for you. Drinking alcohol heavily damages your liver, and the liver works to filter contaminants out of the body. When that’s not occurring effectively, the buildup of toxins and the like affects your immune system. And most of the many harmful chemical in cigarette smoke work similarly.
There’s a thousand reasons why you shouldn’t drink excessively or smoke, and this is just one more very valid one like all the other ones.
7. Be Proactive in Preventing Infections
This involves being smart and wary of know ways that viruses and pathogens are commonly transmitted to people. Wash your hands frequently, cook meats thoroughly, etc. Being very cleanly will keep you in good stead and boasting a nice tip-top immune system.
8. Be Wary of ‘Quick Fix’ Supplements
Many products on store shelves state that they will boost or support immunity, but in reality there really are not ‘quick fixes’ for boosting your immune system via under-the-counter supplements. Further, boosting the number of cells in your body — immune cells or otherwise — isn’t necessarily advisable. To put that in perspective, consider this; athletes who pump blood into their systems to boost their number of blood cells and enhance their performance run the risk of suffering a stroke. There’s no concrete definition of how many cells or what mix of them allows the immune system to function at its best.
No one likes to have their weekend wasted by the flu, being laid up for a month by mono, or anything of the sort. Your immune system is the last line of defense against all of these misfortunes, so make sure you do all that you can to ensure yours is primed to combat at full force all the time.
