If you're suffering from your second or third cold of the season wondering 'Why God Why' this keeps recurring, the answer may lie in your methods of cold prevention.

According to a study published in the Canadian Medical Association Journal, much-loved methods - which include ginseng, vapour rubs and homeopathy - prove inconclusive. And that favourite tablet of the nation - vitamin C - is utterly useless once the cold develops.

Instead, the best preventatives and methods for when you have the cold are washing your hands and taking zinc.

Do I Have The Flu?
Temperature(01 of23)

Feeling feverish or having a fever of 100°F or higher can be an indicator for the flu or H1N1 virus, though not everyone with the flu will get a fever. Fevers are unlikely with a common cold. (credit:Shutterstock)
Body Aches(02 of23)

Feeling achy all over or getting a headache is another symptom of the flu or H1N1, and not generally associated with getting a cold. This tends to show as more general aches, as opposed to those confined to one area. (credit:Shutterstock)
Nausea, Vomiting Or Diarrhea(03 of23)

Nausea is the most symptom of the flu, and less likely to occur with a cold. However, if you're vomiting continuously, this can indicate a more severe strain of the flu, and you should seek medical help. (credit:Shutterstock)

To help keep the germs at bay, use a cotton swab to apply petroleum jelly to the inside of your nostrils. Voila! You've got yourself an enhanced germ barrier. Our noses are often soft spots for bacteria and viruses and a small layer of jelly can act as a protective barrier. (credit:Shutterstock)

Kids are primary germ carriers and will inevitably fall ill this season. To prevent yourself from getting sick, make sure your children are also protected either with a flu shot or medication. (credit:Shutterstock)
Get Fresh With Garlic (17 of23)

Bacteria love warm, humid environments. If what you've got now is a bacterial infection, garlic is a powerful, all-natural antibiotic solution. Of course we're not telling you to eat a raw clove straight — instead try adding garlic to soups, salads or your favourite pasta. (credit:Shutterstock)
Reach For Probiotics (18 of23)

A happy gut means a healthy immune system. Reach for probiotic supplements or yogurt. Probiotics can boost the immune system and increase resistance to the cold and flu by producing antibiotics. (credit:Shutterstock)

Lack of sleep is proven to contribute to an unhealthy immune system. To ensure you have a congestion-free sleep, whether you're sick or not, use a nasal strip to help open your airways. (credit:Shutterstock)

Much like hand washing, this is one of the simplest ways to help prevent the spread of germs. (credit:Shutterstock)
Shower Your Nose (21 of23)

Irrigate your nasal cavity with a neti-pot. It will flush out the viruses and bacteria reducing chances of impending infections. (credit:Shutterstock)
Don't Forget The D (22 of23)

When it comes to the flu, it’s not all about Vitamin C, Vitamin D is just as important. Since we may not get as many hours of sunshine as we do in the summertime, taking vitamin D supplements during the winter can help boost immunity and protect our bodies from catching a cold.

Research suggests the use of a properly formulated Echinacea means fewer colds, reduced duration of cold symptoms, and less reliance on synthetic pain relievers. (credit:Shutterstock)

A new review by Dr Michael Allan, of the University of Alberta in Canada, and Dr Bruce Arroll, of the University of Auckland, New Zealand, based their findings from 67 trials.

They discovered that zinc supplements of 10 or 15mg a day works for children, resulting in lower rates of colds and less time off school caused by colds, and believe it would also help adults.

As for what to take once you have symptoms, paracetamol, ibuprofen and perhaps antihistamine-decongestant combinations are among best treatments.

On average, said the Mail Online, the common cold strikes 930,000 Britons, on average, on any day in winter, with more than 200 viruses to blame.

"Adults can expect to suffer between two and five colds a year, although they don’t always lead to symptoms. Symptoms such as sore throat, stuffy or runny nose, cough and malaise are usually worse for the first three days but can last up to three weeks."

Some people also mistakenly take antibiotics to cure colds, which won't work as they are viral illnesses, not bacterial.
