So you’ve got a cold – nothing you can do about it, right? From the truth about vitamin C to the power of your mood, here’s the latest science to help you get well soon

Cold-curing tips
Cold-curing tips

At this time of year the common cold is, er, pretty common, and we’re all in the firing line. Most of us will have at least two colds this year – snotty ordeals that turn us into sniffling zombies clutching vials of Olbas Oil and saying things like, ‘My hair hurts.’

There are 200 different types of the common cold virus. The most prevalent ones are rhinoviruses, closely followed 
by coronaviruses, adenoviruses and coxsackieviruses. ‘When these viruses get into your nose, they irritate the lining, causing it to produce mucus to try to expel the bad stuff,’ says clinical scientist Professor Peter Openshaw. ‘The virus sticks to the cells in the nose then ruptures, travelling to the airways and other parts of the upper respiratory tract, including the throat.’

So what can we do to protect ourselves? Well, as the saying goes, prevention is better than cure. ‘Alcohol-based hand sanitisers are more effective than you think,’ says Dr Adam Simon, GP and medical officer at ‘Washing your hands regularly is always a good idea but be aware that antibacterial soaps don’t kill viruses and as such won’t prevent the spread of colds.’ Office martyrdom doesn’t help, either. ‘The best way to prevent a cold outbreak is for the person who has the virus to stay at home and rest.’ But there is another way to get ahead of the game in the face of all these airborne contagions – know your facts.

Myth or truth? 
A cold is the same 
as the flu
Colds and flu are both caused by viruses, but it’s quite difficult for doctors to determine which one we are suffering from. The term ‘influenza-like illness’ or ‘ILI’ is, in medical settings, also used for colds, especially when a fever is present. Both viruses attack the cells of the adenoids at the back of your throat, spreading to cells in the rest of the upper respiratory tract (ie, the nose, throat, pharynx 
and larynx).

‘If you have more severe symptoms, a fever of 39.5 and you’re aching all over, it’s more likely 
that you have got an influenza,’ says Sebastian Johnston, professor of respiratory medicine and allergy 
at Imperial College London. ‘But influenza only really happens during annual influenza epidemics – we normally have one every year [from October to May], they vary in severity and will last six to eight weeks in more highly populated parts of the country before spreading.’

Currently, the World Health Organisation (WHO) recommends the flu jab for pregnant women, health workers, people over 65 (or under five) and those with chronic health conditions. But it is available for everyone (ask your GP) and is the only reliable protection.

Myth or truth? 
Common colds are
 spread by kissing
True, but more than that, you don’t need to kiss or even touch a stranger to pick up the germs. ‘The virus particles of the common cold are spread through the small droplets of saliva in the air when someone with the infection coughs, sneezes or even laughs or talks,’ says GP Dr Sarah Brewer.

‘The particles are propelled at an estimated speed of around 100mph and can travel for many metres [recent research* shows that a single cough would fill about three quarters of a two-litre bottle with air containing 3,000 droplets of potentially infectious saliva]. They may then enter a nearby person’s body through the eyes, nose or mouth.’ In addition, germs from their hands linger long after they’ve gone, contaminating surfaces such as door handles, escalators and keyboards on which the virus is able to survive.

Myth or truth? 
Vitamin C will help
 prevent colds
Mmm, not so much. ‘Research shows that vitamin C is only really effective in the prevention of colds when 
the human body is under significant stress – for example in soldiers or 
long-distance runners,’ says Dr 
Ashton Harper, medical advisor for pharmaceutical company Protexin. Professor Openshaw agrees. ‘The vitamin C myth really doesn’t have 
a good scientific basis,’ he says. ‘There’s no harm in it, but it is not a cure.’

In fact, much on offer at your local pharmacist will have negligible effect. ‘There’s no good evidence, for example, that cough medicine works,’ says Dr Davina Deniszczyc, medical executive director at Nuffield Health. ‘But, interestingly, in clinical studies, placebos (sugar pills) work really well.’ Indeed, research from the University of Wisconsin found that when patients received a placebo pill that they believed contained echinacea, their illnesses were substantively shorter and less severe. So whatever your medicine of choice, if it’s safe and seems to work for you, stick with it.

Myth or truth? 
The number of colds you
 get is down to genetics
Partly true. ‘We all have what we call innate immune systems, which protect us against viruses we’ve never seen before,’ says Professor Johnston. ‘We also have acquired immunity, where our bodies “learn” from infections we’ve seen previously and have immunity to them [such as mumps or chickenpox].’ The number of colds we get depends on how strong both these immune systems are. ‘People vary depending on their genetic make-up and there are at least 40 genes found to control our immune defences,’ adds Professor Openshaw. ‘So you may simply be lucky or unlucky in terms of the pattern you’ve inherited.’

Myth or truth? 
Being miserable makes 
you more susceptible 
to the sniffles

This one’s actually true. ‘Maintaining a positive mental attitude can help prevent illness,’ says Justin Jones, national physiology manager at Nuffield Health. ‘This is because we release different hormones depending on our outlook. Thinking positively has been proven to release the immune-boosting hormone DHEA, while thinking negatively releases the immune-suppressing hormone cortisol.’ So being upbeat can help you stay healthy.

Professor Openshaw agrees there’s some science behind this idea. ‘One of the last studies that was ever done at the Common Cold Research Unit in Salisbury before it closed showed that if people feel miserable and out of control in their lives then they are more likely to be infected by a standard dose of common cold virus.’ So chin up, and look on the bright side, you will be doing your nose a favour.

5 Cold remedies that actually work (according to the experts)

1 Zinc lozenges
A study by Helsinki University found zinc lozenges can shorten a cold by about four days. ‘Don’t exceed 100mg of elemental zinc per day,’ says lead author Dr Harri Hemila. Nature’s Way Zinc Lozenges (£2.93 for 60,

2 Probiotics
‘The majority of our immune system is in our gut,’ says Dr Harper. ‘Probiotics have been shown to significantly reduce the severity of cold symptoms.’ Choose a high- quality multi-strain product such as Bio-Kult Advanced Formula Probiotics (£8.99 for 30,

3 Echinacea

This one’s still up for debate, but recent research by Professor Johnston at the Royal Society of Medicine showed echinacea reduces (by about 50 per cent) recurrent respiratory tract infections. A Vogel Echinaforce Hot Drink (£9.99,

4 Paracetamol
‘Nothing can prevent a cold, so it’s a matter of symptom relief,’ says Professor Johnston. A Southampton University study found paracetamol was superior to ibuprofen when it comes to treating colds. Paracetamol (39p for 16,

5 Vitamin D
‘A lot of people are deficient in vitamin D in the UK and there’s evidence boosting it can help resistance to infection,’ says Professor Johnston. Research shows in order to activate an immune response, vitamin D must kick-start T cells in our body, which can attack and neutralise any threat. ImmiFlex (£13.39 for 30,
