The average adult catches two to four colds a year. Here are the best ways to ease symptoms

There’s nothing worse than feeling a cold coming on. Those familiar symptoms – sore throats,
runny noses and body aches – strike children twice as many times a year as adults, with pregnant women and older people also likely to suffer more with them.

How well we fight them off can be related to stress, sleep, diet, alcohol intake, smoking and even sex (yes, that boosts our immunity).
“A lot of the symptoms we experience when we have a cold are due to our immune response, and not the virus itself,” explains Dr Lindsay Broadbent, a lecturer in virology at the University of Surrey. “For most common cold-type viruses you just have to let them run their course, but by easing symptoms you’ll feel better and possibly shorten how long you suffer for.”
Here is our guide to staving off a cold – or helping your sniffly child through one at home.
The best thing you can do for your cold-ridden body is absolutely free and will be welcome news: get into bed.
“Our circadian rhythm (internal clock) and sleep are linked to our immune system, and not getting enough sleep is associated with a higher risk of getting respiratory infections,” says Dr Broadbent. “A study found subjects who slept for seven hours or more were almost three times more likely to develop a cold than those who had eight or more hours shut-eye.” Fundamentally, our bodies need rest to recover.
Dr Chris Smith is a consultant who specialises in clinical microbiology and virology at the University of Cambridge. He says that a lack of sleep also makes us less efficient at responding to preventative vaccines, like a flu jab. But the main reason sleep helps is more simple. “Essentially, how much you’re suffering with a cold is about how you perceive the symptoms, and while you’re asleep you won’t notice them,” says Dr Smith. “Hence why we use the phrase ‘sleeping it off’. You will likely feel tired when your body is busy fighting infection, so give in to it.”
If you can’t sleep because of your blocked nose, using pillows to prop yourself up may help and make sure any over-the-counter drugs taken at nighttime don’t contain caffeine.
We’ve all had doctors instruct us to “drink plenty of fluids” when we’re suffering from a viral infection. Although there’s limited evidence as to why this may be effective, it’s thought hydration levels may promote the action of immune cells.
You don’t need to gulp down litres of water – tea and coffee also work. “Any fluid is better than nothing, and tea and coffee are mostly water anyway,” Dr Smith says. “Drink when you’re thirsty, there’s no need to force gallons down.” Caffeine might also pep you up if you’re feeling sluggish.
He does advise steering clear of alcohol (step away from that whisky hot toddy) which will suppress your immune system further. But even sugary sweet drinks get the green light. “If someone is running a fever and a fizzy drink is the one thing they crave, that’s fine, the extra calories won’t hurt especially if you’re feeling less like eating.”
Recently, scientists have found that saline nasal drops can reliably shorten a child’s cold by two days, in addition to reducing the risk that they’ll pass the bug on to their parents or other family members.
A recent study has found that giving children a solution made of just salt and water can cut the duration of a cold by two days. “We found that children using salt water [saline] nose drops had cold symptoms for an average of six days where those with usual care had symptoms for eight days,” said Prof Steve Cunningham of the University of Edinburgh, who worked on the randomised controlled trial.
“The children receiving salt water nose drops also needed fewer medicines during their illness.”
A solution with the salt concentration used in the study – of 2.6 per cent – can’t be bought over the counter, but is easily made at home.
Simply mix three teaspoons of iodine-free salt with one teaspoon of baking soda, and store it in an airtight tub.
When you want to put a solution together, combine a teaspoon of that mixture with around 200ml of boiled water, then wait until it’s lukewarm before using. If it burns or stings your child’s nose then water the solution down.
Julie Macken, a medical herbalist who founded the natural skincare company Neve’s Bees, suggests drinking water sweetened with elderberry syrup. “Elderberry has been found to shorten the length of time from illness caused by both influenza A and B viruses, and can also be used prophylactically (preventatively) during the winter months.”
You can make your own by simmering 2.5kg of fresh ripe elderberries in a saucepan (no water needed), then when soft, mash and strain through a sieve, adding 500g sugar to the strained juice and gently simmer for 20 minutes. Once thickened to the consistency of runny honey, pour into sterilised bottles. The berries can be foraged in the autumn, but freeze-dried ones are sold in all whole food stores and online.
“As well as the berries, elderflowers are also very helpful and encourage sweating to break a fever,” adds Macken. “Use one heaped teaspoon of dried flowers per cupful of boiling water and allow to infuse for five minutes.”
A warm drink made with honey is the first thing Dr Broadbent personally reaches for when she feels a cold coming. “Honey has antimicrobial properties, it soothes my sore throat and tastes pretty good,” she explains. It’s the syrupy qualities of honey that calm a raging throat. Studies on children with symptoms ranging from a runny nose to fever found that a single night-time dose of honey may have a small influence on their cough and aid sleep.
Garlic, meanwhile, has long been in medicinal use. “Chinese herbalists were documented as using it as far back as 2700 BC,” observes Macken. “It has antimicrobial and expectorant activities, which helps you to loosen up phlegm.”
Macken suggests making this “honey garlic” concoction: crush 3-4 peeled garlic cloves in a pestle and mortar, cover with 3-4 teaspoons of good quality honey and leave for 24 hours. Start by eating one teaspoon, but it will keep for many months. “It might not sound appealing but for respiratory infections and chesty coughs it works wonders,” says Macken.
Similarly, ginger is a natural ingredient often hailed as a cold-buster. “Very strong flavours producing that warming sensation in ginger does act as a strong distraction from, say, your runny nose,” says Dr Smith. “So some of these remedies work in placebo ways, i.e. the fiery sensation in your mouth stops you dwelling on your blocked up nose.”
Many of us stock up on tubes of tablets that fizz in water hoping they will offer some protection, or reach for orange juice.
“One review of published studies suggests that vitamin C may have more of a noticeable effect when someone is suffering from more severe symptoms,” says Dr Broadbent. One study she cites found that taking 1-2mg of vitamin C daily cut the duration of colds by 8% for adults and 14% for children, as well as reducing the severity of symptoms.
But there are caveats. “One of the biggest misconceptions is that you can fend off a cold by loading up on vitamin C in isolation, which will likely just result in very expensive vitamin C-rich urine,” Dr Smith explains.
“If you are well nourished from eating well, you will be better defended against a virus,” he adds. “The only thing that cures a cold is your immune system, so you need to get that working as efficiently as possible overall.”
Dr Smith doesn’t recommend wasting money on any supplements, with the one exception of vitamin D, which he takes himself. “We don’t get enough sunshine in the winter in the UK to make it the natural way,” he says. “Vitamin D affects the tone of your immune response, so this is worth topping up on.
“During Covid, some studies associated a deficiency in vitamin D with more severe disease,” adds Dr Broadbent.
The mineral zinc is also often thought to help reduce the length and severity of a cold if you take it early. “Zinc helps boost the neutrophils (type of white blood cell) that act as your immune system’s first line of defence,” says Macken. Zinc-rich foods include cacao powder and cashews as well as other nuts, seeds and beans. Studies have suggested that combining zinc with vitamin C could provide even quicker symptom relief.
Echinacea – a group of flowering plants in the daisy family – has long enjoyed a reputation as a dietary supplement to ward off colds. “The use of it is based on the idea that it might stimulate the immune system to more effectively fight infection,” explains Macken. “Both the roots and the flowers and it’s often taken as an infusion in a drink or as a tincture in alcohol.”
While studies show taking echinacea might slightly reduce your chances of catching a cold, it won’t shorten the length of a cold and most virologists wouldn’t promote it.
Head to your high street chemist and you’ll be faced with a dizzying array of cold-busting products, but you needn’t spend a fortune.
Simple paracetamol and ibuprofen are the winners for Dr Chris. “They won’t clear an infection but they will help lower temperatures and relieve headaches. Both things should be used as symptom relievers so you can take it easy and recover, rather than taking pills so you can keep on working at full pelt.”
For tackling sore throats he suggests gargling aspirin. “This takes the drug directly onto the tissue that’s inflamed, making it excellent symptomatic relief. Gargling salty water – making sure to spit it out afterwards – also works.”
“Some nasal sprays may change the environment in your nose,” says Dr Broadbent. “Which means that any viruses released from your infected cells have a hard time infecting other cells in your airways.”
Dr Simon Clarke, an associate professor in cellular microbiology at Reading University, recommends using Vicks First Defence when you first notice cold symptoms. “It snares the virus in your upper airways and nasal cavity and stops it spreading,” he explains, adding that if you catch it early he finds it works “about 80% of the time”.
Night Nurse is the best-known brand in the UK and some chemists have their own version which generally contain paracetamol (to ease aches), promethazine (sedating antihistamine) and dextromethorphan (cough suppressant). Many people find this combination can aid sleep, which is crucial for feeling better.
“What these types of drugs can do is unclog your airways,” explains Dr Smith.
“Everyone assumes a blocked up nose means massive amounts of snot clogging it up. While you might have slightly more, the real issue is that the hole the snot has to get through (your nasal passage) has shrunk because the inflammation has caused the airway tissues to double in size. It’s this constriction of space in the nose that makes you feel blocked up.
“So first these drugs reduce secretions, and secondly they constrict blood vessels, reducing inflammation in the airways. Bluntly put, the amount of space that you’ve got available for the snot to fit through becomes bigger so it’s easier to breathe.”
“Menthol or eucalyptus rubs and gels can help us feel like we are breathing clearer even though, in reality, the reason we can’t breath through our nose is due to inflammation in the lining of the airways,” says Dr Broadbent.
Using a dollop of Vicks vapour rub in a bowl of hot water and allowing the steam to clear your airways (covering your head with a towel) is an old trick for clearing congestion. “Peppermint has excellent decongestant properties and helps clear thick catarrh, whether from the sinuses, ear or lungs,” Macken explains.
