So is it inevitable you’ll catch it too – as you
socialise at festive parties and rush around in the cold trying to fit
everything in before Christmas – or is it possible to defend your immune system
and avoid it?
Well, it seems some of us are more susceptible than
others, say if we are tired, run-down, or suffer from other conditions.
Dr. Nadja Auerbach, at Thriva says: “People with
some medical conditions are at increased risk of infections. For example,
people with conditions like asthma, COPD, and diabetes, or who are
immunosuppressed.”
For them, staying safe is essential, and they
should seek advice from a doctor on how to protect themselves. But, for people
without medical conditions, “lifestyle can have a big effect on your immunity”,
says Auerbach.
So, how can we avoid catching these horrible germs?
Chill out
Yes, sometimes just kicking back can help protect
our immune systems.
Being more vulnerable can come from “everyday
occurrences such as too much stress and not getting enough sleep”, she says.
So, don’t be afraid to hibernate this winter and
destress from the busy year. Spending some time on your own will also reduce
the number of people you may be exposed to.
Drink more water and less booze
If you are regularly “getting dehydrated, and binge
drinking,” you are making yourself more vulnerable, according to Auerbach. It
may be difficult when so much of the season is spent eating and drinking, but
make sure you are having a bit of balance, and drinking plenty of water too will
help lower your risk of getting sick.
“A lifestyle with healthy habits is key in
minimising your chances of getting an infection,” she says.
Eat immune-boosting foods
“The best approach is to maintain a balanced and
nutritious diet full of vitamins, minerals, and antioxidants,” says Dr. Rhianna
McClymont, GP at Livi. “All the usual suspects – lean meat, fish, grains,
pulses, and five portions of fruit and vegetables a day.
“Try to have a mix of colours on your plate. The
wider the variety of colours you eat, the more types of phytochemicals [the
chemical compound produced by plants] you consume, which are essential for
fighting inflammation in the body,” she says.
“If you don’t always have the fresh foods in, stock
up on a few portions of frozen or tinned fruit and veg. This alternative is
just as nutritious as fresh because it’s frozen so quickly after being picked.”
Try vitamin supplements or prioritise vitamin-rich
food
“To go one step further, make sure your diet includes a mix of vitamins and minerals associated with a strong immune system,” says McClymont.
She suggests: “Vitamin A – which can be found in
liver, milk and cheese, and green leafy vegetables. Also try to prioritise vitamin
C – found in oranges, tomatoes, kiwis, blackcurrants, peppers, and broccoli.
[And] vitamin D – found in oily fish, eggs, fortified breakfast cereals, and
dairy products.”
Lesser known vitamins try and include more of in
your diet including zinc, “found in meat, poultry, eggs, cheese”, she says. “As
well as root veg, nuts and seeds, and selenium which can be found in wholegrain
bread, eggs, poultry, fish and shellfish.”
Wear a mask and wash your hands
“Masks, particularly in mass use, can reduce the
risk of airborne infections,” says Dr. Sanjay Mehta, GP at The London General Practice, “which is the route of transmission of many of the infections
currently sharply rising in the UK. Regular handwashing can further reduce the
transmission risk too.”
Stay on top of vaccines and boosters
“Many viruses and other infection-causing bugs make
it through this initial barrier [of masks and hand santisation] and into the
body, so looking after your immune system is just as important, to maximise
your defence,” says Mehta. “That includes keeping up-to-date with the annual
influenza (flu) jab and covid boosters, which helps to reduce the risk of
transmission and severity of such infections.”
