- Balance your immune system, don't just boost it
- Gut health is central to immune function
- Daily habits beat quick-fix solutions
There is, quite understandably, a strong focus on immunity for all of us. It's not surprising therefore, to read and hear about the importance of 'boosting' our immune systems with various quick-fix solutions.
To have robust immune defence mechanisms is something we should all strive for (it's vital for longevity). To have a keen interest in supporting the immune system offers some security towards remaining fit and healthy and reducing the likelihood of becoming more susceptible to complications from infections.
Rethinking the 'Boost' Approach
However, I'd argue that boosting is a red herring, and that we're possibly focusing on the wrong thing. Instead, it might be more beneficial to consider how we optimise an appropriate immune response to infection, or just ensure we're resilient.
The fact is that the immune system's response to an infection may well require a degree of 'boosting' as part of its initial response, but careful management of this is needed, and ultimately, resolution is what's required following a cycle of important processes. I prefer to talk about 'balancing' the immune system, rather than boosting it, because in understanding this subtle difference there is more opportunity to make ongoing, positive actions each day to stay well.
Understanding the Immune Response Cycle
The different steps required for optimal immune function involve the production of certain inflammatory and anti-inflammatory chemicals, which are often hallmarked by signs and symptoms of illness, for example, a temperature.
A temperature is a good example of an important stage in an immune response, and it should – ideally – be left to manage itself in its own time without too much intervention (obviously this isn't advised if a temperature goes very high). A moderate temperature that is left to 'do its thing' is a very useful immune balancing strategy to adopt, where possible. Its rise, then fall, helps with the important, final 'signing off' that resolution brings. It starts with boosting, but you don't want the boosting to perpetually cycle upward.
The Gut's Role in Immune Function
Our gut plays a pivotal role in the communication cycle of an immune response, from activation through to resolution. Researchers are beginning to understand just how important microbes are in both educating our immune cells to work effectively, but also in signalling the all important 'sign-off' needed to prevent ongoing, chronic inflammation that may come with lingering symptoms.
Ultimately, to help give our immune systems the best chance of being balanced and well equipped to deal with infections in a timely fashion with minimal issues, we can implement simple tools and techniques into our daily lives to help us be more resilient when it comes to infection.
Tips for Immune Balancing to Support Resilience
Eat a Mediterranean Diet
This approach to eating, which focuses on enjoying a wide array of local, seasonal foods, rich in vegetables, fruits, fish, meat, nuts, olive oil, herbs and spices has been demonstrated as having a positive effect on balancing inflammatory processes. This is good news for the immune system as a whole.
Make Gut Health a Priority
The diet described above supports a diverse and immunity-friendly gut ecology, but targeting the gut with beneficial bacteria from probiotic foods and supplements may also be beneficial.
Manage Stress
Do this by adopting healthy lifestyle practices, such as regular, sensible exercise or meditation, helps keep levels of the hormone cortisol at appropriate levels. Too much cortisol, which we produce more of under stress, has been shown to interfere with the crucial resolution phase of an immune response.
Prioritise Sleep
This is incredibly helpful for supporting a balanced immune system, most notably because of its impact on melatonin production; an important immune modulator.
The Path Forward
Rather than chasing the latest immune-boosting trend, the most effective approach is to focus on consistent, daily habits that support your body's natural ability to respond to and recover from infection. By prioritising whole foods, gut health, stress management and quality sleep, you're not just preparing your immune system for occasional challenges, you're building lasting resilience that serves your overall health and longevity. These aren't quick fixes, but they are the foundations of genuine, sustainable wellness.
