How to Support Your Immune System When It's Running Low
Posted: August 12, 2022
Here’s how to look after your immune system as flu season approaches…
Editor's Note: Is it just because we're getting older, or is time really go by faster. It's hard to believe that Labor Day is just around the corner and with it the traditional end of summer and not far behind the beginning of flu and cold season. Here with some advice on preparing for that transition is a piece from Stylist by Chloe Gray that we found on Pocket. Following is an excerpt (with more details indicated by ". . . "), with a link to the full article at the bottom of the page.
When the mornings get darker, the days become colder, and coats and boots slowly starting to re-appear in our wardrobes and shops, it’s probably time we start preparing ourselves for our winter colds, too.
We are naturally more susceptible to colds during the winter, but there are ways to fight back. While “boosting your immune system” is an inaccurate phrase, looking after your immunity is still important. According to Dr Sarah Brewer, a GP and the medical director of vitamin and supplement brand Healthspan, a strong immune system is the key to staying healthy no matter what the elements throw our way. The immune system “protects against disease by recognising and attacking infections,” she explains.
It functions in two ways: ‘innate’ immunity (protections that are programmed into all of us as general defences against disease) and ‘acquired’ immunity (specific measures in the body aimed against a particular infection once we have encountered it for long-term immunity – how vaccines work).
What are the signs of a low immune system?
A ‘low’ immune system simply means that you are more likely to experience symptoms when exposed to a common cold virus or bacteria. So, the most common sign that your immunity is low is that you have frequent or prolonged colds (pre-Covid, the average was around one cold a year, lasting seven to 10 days).
Why is my immune system low?
There are many reasons why someone might have lower than usual immunity. Dr Brewer says that “one theory is, as people get older, they develop more vitamin and mineral deficiencies that contribute to reduced immunity with higher levels of inflammation”. She points to a recent study from Oregon State University which found that people aged 55 and over who took a daily multivitamin and mineral supplement for 12 weeks were able to fight off infections twice as fast as those taking a placebo.
But it’s about more than just nutrition. Have you ever noticed that you get wiped out with a cold just before a job interview or big event? That’s because stress has a huge impact on our immunity, says Dr Brewer: “Numerous studies have demonstrated that long term stress has the ability to reduce the functionality of key components of the immune system which can, in turn, leave you open to infection.” . . .
Post-Covid cold’s are also expected to soar. That’s because, for the first time in a long time, we’re all inside again. Whether it’s offices or restaurants, being around each other for the first time in a long time does mean that infections will spread.
How can I support my immune system?
Getting in the right nutrients is essential for optimum functioning of the body – including the immune system. Vitamin D and vitamin C are what to focus on. . . (See the full article for links to several research reports on vitamins D and C)/p>
While the NHS recommends taking a vitamin D supplement, especially during the winter months, we should also try to focus on “eating a Mediterranean style diet with plenty of fruit and vegetables, onions, garlic, oily fish and wholegrains” to ensure that we are giving our immune systems the nutrients it needs to function, says Dr Brewer.
Other lifestyle tweaks you can make to support your immunity include exercise, . . .
And get some sleep! . . .
Then there are natural supplements you can take. . . .
And, at risk of sounding like Boris Johnson, washing your hands is essential, as is wiping down keyboards, doorknobs and phones. Be alert to the key symptoms of coronavirus, and take lateral flow tests regularly to ensure that your sickness isn’t the virus. Dr Brewer also urges everyone to talk to their doctor about getting an annual flu vaccination.
