The first hint of a cold is your best chance to act. UK doctors share eight science-based moves to shorten symptoms without wasting money on hype.
A scratchy throat or a sneeze can signal a cold on the way.
Most colds clear in about a week, but those first hours can still influence recovery.
Jimmy Mohamed told RTL that many over‑the‑counter cold remedies are "the scam of the century".
He says room disinfectant sprays "At best, it smells clean".
On throat syrups with alpha‑amylase, Jimmy Mohamed concludes "Your money is spent for nothing".
Faïza Bossy told Marie Claire that "It is used to strengthen collagen fibres, to reinforce the skin, bones and cartilage, to protect blood vessels, gums and ligaments. It also contains antioxidants that protect cells from oxidative stress. Finally, it plays a key role in the normal functioning of immune cells".
She cites the Medical Journal of Australia, which reported that "Doses above 1 g per day, taken as soon as symptoms appeared, did not reduce the duration or severity of the common cold in healthy adults compared with a normal intake". She says "In this context, taking 1 g of vitamin C, for example, is quickly eliminated in the urine. So it is better to spread intakes out over the day, in order to maintain more stable concentrations, notably thanks to food". She adds that "So, if you feel your immunity weakening, you can use vitamin C in food supplements, but it remains an occasional tool and does not replace a diet rich in fruit and vegetables that are high in vitamin C".
Dr Hooper told Women’s Health UK that "Getting good quality sleep, ideally at least seven hours, supports immune system function," and that "When cold viruses infect the upper airways (nose, sinuses and throat), the immune system reacts. We produce chemicals called cytokines, which trigger symptoms like a blocked or runny nose".
She says "Drinking more water and fluids helps the mucosal lining work at its best to defend against infection".
On vitamin C, she says "Taking vitamin C regularly (1 to 2g per day) may reduce the length and severity of common cold symptoms," but warns that "It works best when taken before symptoms appear".
On zinc, she notes that "Zinc lozenges taken within the first 24 hours of a cold, at a total daily dose of 75 mg, may speed recovery," yet warns that "The taste can be unpleasant, and it may cause nausea," and that "Zinc is not recommended for children, those who are pregnant or breastfeeding, people with kidney disease, or anyone with zinc sensitivity or allergy".
She notes that "It helps stop germs spreading at home or in the office".
She advises "If things aren’t progressing as expected or you’re worried, it’s better to seek medical help sooner rather than later," because "Severe symptoms such as shortness of breath, chest pain, fever that doesn’t respond to over-the-counter medicines like paracetamol or ibuprofen, or confusion may signal a more serious illness and require urgent medical attention," and reminds us that "The most common complications of a cold are sinusitis, otitis media (middle ear infection) and pneumonia".
On stress, Dr Hooper explains that "The immune system is sensitive to stress, so minimising extra pressure is sensible".
Alongside these eight steps, doctors emphasise rest, fluids and saline rinses while your immune system clears the virus over several days.
