Revitalized Focus on Immune Health
In the wake of COVID-19, the topic of health has surged to the forefront of public concern. This novel coronavirus presents a formidable challenge, capable of affecting even those who are typically robust. Regardless of the pandemic’s presence, fortifying our immune system remains essential to our overall health.
According to naturopathic doctor Brian Davies, who founded Westcoast Integrative Health Inc., current medical definitions of health encompass a complete state of physical, mental, and social well-being, rather than merely the absence of diseases and ailments.
“Achieving health is a continuous journey,” he emphasizes, “and should not be taken for granted. This definition underscores the significance of harmonizing our physical, mental, and social-emotional wellness.”
Understanding the Immune System
To effectively nurture our immune defenses, it’s crucial to comprehend their workings. Primarily, the immune system operates to shield us from harmful microorganisms, comprising two key components.
- Innate immunity is our body’s first line of defense, which includes physical barriers like skin and immune cells that swiftly combat invading pathogens, often resulting in responses such as fever.
- Adaptive immunity develops over time, learning to recognize and respond to new germs. Upon first exposure to a pathogen, our immune system may react by causing illness, but it subsequently remembers the invader for a quicker defense in future encounters.
A well-functioning immune system does not guarantee immunity from illness. Contrary to common belief, the presence of illness may indicate that our immune defenses are actively responding to threats, as we’ve seen with the SARS-CoV-2 virus responsible for COVID-19.
Symptoms as Signs of Immune Activity
“Experiencing symptoms such as fever, cough, muscle aches, and headaches signifies that your immune system is actively combating infection, rather than indicating a mere presence of illness,” explains Ashley Stapleton, naturopathic doctor at Edgemont Naturopathic in North Vancouver.
“Being healthy doesn’t mean an absence of illness; it means that if you do fall ill, you can swiftly and effectively counter the pathogenic threat,” Stapleton adds. “Certain viruses, like HIV or herpes, can bypass even the healthiest immune responses.”
Nonetheless, the worldwide health crisis has fostered an increased recognition of the need for self-care, serving as a valuable reminder.
Boosting Immune System Health
Regardless of external circumstances, prioritizing immune system health is essential. But what does this entail? The approach will vary according to an individual’s unique biochemistry, genetics, and experiences.
“Fundamentally, a healthy lifestyle is vital for maintaining immune health,” notes Davies. “Here are some groups of people who should consider lifestyle adjustments to bolster their immune systems:
- those who consume a lot of processed foods
- individuals with poor sleep habits
- people experiencing high levels of emotional or physical stress from various sources
- heavy alcohol consumers
- smokers
These elements contribute to excessive stress on the body, potentially hindering innate immunity and disrupting our adaptive immune responses.
“Maintaining a healthy blend of moderate exercise, balanced nutrition centered on whole-food proteins, beneficial fats, colorful vegetables, and fruits; sufficient sleep; and mindfulness practices are crucial components to optimal health,” emphasizes Davies.
Age and Immune Function
As individuals grow older, natural immunity typically declines, and biochemical efficiency diminishes. However, it is essential to consider not only chronological age but also biological age.
“Biological age can now be objectively assessed to gauge how our bodies age on a biochemical level,” explains Davies. “When biological aging markers are identified as suboptimal, such as poor immune-cell activation, targeted nutritional and lifestyle interventions can be implemented to address those specific challenges.”
“Ultimately, it circles back to lifestyle choices and dietary habits,” he adds. “The more commitment we show towards our health, the greater the benefits we reap.”
