At certain times of the year, it seems that every other person you see is sniffling, coughing or sneezing and that catching a cold is almost unavoidable. But is there anything that you can do to reduce the chances of catching a cold, or knock it on the head if you're unfortunate enough to catch one? We take a look at the foods that might help.
How to avoid getting sick
In today's society, it's nearly impossible to avoid making contact with people infected with a cold. However, you can try to equip your body to fight viruses and if caught, minimise their duration and symptoms.
Ultimately, it is clear that good mental and physical health are key components for reducing the risk of catching a cold and its duration. Here are a few of the best choices you can make:
Although this can often be difficult in the environment we live in, reducing the stresses we expose ourselves to can reduce our susceptibility to catching a cold. If you are living in a stressful environment, try taking time out to do the things that you enjoy, or regularly listen to mindfulness apps such as Headspace, as this can help to minimise the stress in the body.
Make sleep a priority
When you sleep, your body gets a chance to repair and rebuild your defences. But if you don't get enough shuteye, the chance of poor health can increase, including your susceptibility to catching a cold.
If you struggle to get to sleep, try ensuring you allow yourself some time to unwind before bed. For example, reading a book or doing something else you find calming that does not involve a screen.
Make up for the lack of sun
It is becoming more and more apparent that vitamin D is a key ingredient for keeping many bodily functions healthy, including your immune system. So, getting enough of it throughout the year is crucial for keeping colds at bay.
The best way for us to get vitamin D is from the sun. However, during the months of October through to April, the body is unable to do this due to the angle of sun. This means that a large proportion of the UK becomes vitamin D-deficient through the winter and this corresponds with when most of us get colds.
During the colder months of the year we can make up to some extent for the lack of sun-induced vitamin D by eating certain oily fish, including salmon, mackerel and tuna and products (such as some cereals) which are fortified with it. But you should be taking a supplement too.
And even though we can get more vitamin D in the summer months, the new recommendation for the UK is that adults and children should take 10 micrograms of vitamin D3 per day throughout the year, but especially during the months of and between October and April.
Eat your five a day
Vitamin C is also important for supporting immune function and can be found in many fruits and vegetables. A healthy, balanced diet which includes five portions of fruit and vegetables a day will provide sufficient amounts of this vitamin for the average person.
For the general population, there is little evidence to show that consuming an additional vitamin C supplement will make any significant difference to the risk of catching a cold. However, if you are an athlete training for some sort of physical event, your body is being put through an above-average level of physical stress and in this case there is evidence to show that taking vitamin C supplements may reduce the risk of catching a cold as such stress can compromise immunity.
You have a cold. Now what?
The sad truth is that there is no cure for the common cold. This is because it is caused by a virus and so it won't respond to medications such as antibiotics. As such, you are left only with one option: treat the symptoms.
Chicken soup - the go-to meal if you have a cold - does actually have some scientific backing. When the body is fighting a cold, it goes into an inflamed state. Research has shown that chicken soup reduces inflammation and therefore helps to protect against some of the annoying symptoms of a cold. Note though that it is worth making your own or buying a better quality soup in order to ensure that you get the most benefits possible.
One of the worst things about having a cold is the inability to breathe through your nose. It makes everyday activities feel much more strenuous. However, hot drinks can help!
A study in 2008 found that consuming a hot drink significantly and instantly improved the airflow of those suffering from a cold. There was also a marked improvement in other symptoms like a runny nose and a cough. However, before you go running to buy the expensive sachet drinks with painkillers in them, please note that you can get the same benefits by consuming tablet form painkillers alongside any hot drink, herbal or otherwise. This may be a reason why chicken soup aids cold symptoms too!
Although, for the general population, it is not thought to reduce the risk of developing a cold in the first place, there is some backing for vitamin C's use as a way of reducing a cold's duration and symptoms. The best way to do this would be through eating foods rich in vitamin C such as broccoli, strawberries and kale. Even more reason to ensure you are getting your five a day!
'Starve a fever, feed a cold'
There is mixed evidence on whether this common statement is true. It is believed that both methods (starving and feeding) create a different immune response in the body. Some studies conclude that the response to starving increases immune cells that are best at tackling bacterial infections that cause symptoms such as a fever (often found with a flu), whereas feeding seems to increase the cells which fight off viral infections (like a cold).
