“Optimal functioning of the immune system, it turns out, is dependent upon feeling good.”
Your immune system is your body’s natural defense against illness, and it also kicks in to lead charge over the healing process when you become injured. While we are born with many natural tools that support immune function, we can also strengthen it with tactics such as strategic lifestyle habits.
As the team which has pioneered the medical specialty of age management medicine, Cenegenics is committed to helping patients do everything they can to stay protected against serious illness. For this reason, we take a highly scientific approach to perfectly tuning the body at the cellular level, optimizing overall functioning, including the immune system. Find out more about how your immune system works below and what you can do to make it even stronger.
The core role of the immune system is to prevent against or control infections. It can differentiate among healthy cells and those that pose a threat with the ability to recognize danger-associated molecular patterns (DAMPs). These cells may be dangerous due to infection or other types of damage, such as cancer. Infections, including viruses, also release signals called pathogen-associated molecular patterns (PAMPs), which the immune system recognizes as well.
At the first sign of these issues, the immune system responds to combat the illness or other damage-causing agents. If it can’t activate properly, issues like infection occur. Yet, issues also develop if the immune system is activated when it shouldn’t be, as seen in conditions such as autoimmune disorders and allergies. The immune system must therefore function optimally to maintain health. 
The immune system is complex and far-reaching, encompassing many different cell types which each have a specific role. With that being said, every immune cell originates from precursors in bone marrow and ultimately develops into a mature cell through changes which take place throughout the body. Here are the key players in the body’s immunity:
In certain individuals, the immune system doesn’t work properly due to an immune system disorder. There are several factors that can impact immune system functionality, including:
Under normal circumstances, the immune system responds to issues like injuries and illness through acute inflammation. The blood vessels dilate, resulting in redness and swelling, so that white blood cells can swarm the affected area and promote healing. The damaged tissue releases cytokines, or emergency signals, which recruit immune cells, hormones, and nutrients to address the issue. As healing takes place, the acute inflammation fades.
Yet, if inflammation lasts too long or occurs when it’s not needed, chronic inflammation ensues. Also known as persistent, low-grade inflammation, chronic inflammation may have long-term effects throughout the whole body. It results in a consistent, low levels of inflammation which are detected by increases in system markers in the blood. Systemic inflammation has been linked to heart disease, stroke, and autoimmune conditions such as lupus. 
Aside from medical issues that prevent the immune system from working as it should, there are several other factors that impact immune system functionality and potentially trigger chronic inflammation, such as:
Fortunately, just as there are many lifestyle factors that can impede immunity, there are also ways you can adjust your habits to boost your immune system.
While your body already has lines of defense in place to ward off illness, you can still strengthen the immune system with the following simple practices.
Optimal immune function is critically important to keeping you protected against everything from the common cold to serious illness. Cenegenics patients have the unique advantages of working closely with their physician and clinical teams to improve biomarkers that influence immunity, including those related to chronic inflammation, insulin sensitivity, cardiovascular and pulmonary function, and more.
By improving these metrics, incorporating the lifestyle factors mentioned above, and utilizing nutraceuticals that include, but are not limited to, Vitamin D3, Vitamin E, Vitamin B6, zinc, and Vitamin C, Cenegenics strengthens patients’ immune function to prepare them for seasonal and other illnesses.
Within just 30 to 60 days on our program, patients begin to feel dramatically better. Their biological age is rebalanced to where it was in their 20s and 30s, and they become better equipped to fight off illness both now and into the future. In fact, so many people trust our ability to optimize their wellness that a quarter of our patient base is made up of doctors and their family members. One of our doctors has even written the textbook on age management which other physicians now study.
