The arrival of colder weather usually brings a wave of sniffles, sore throats and the familiar routine of tissues and hot drinks.
While most people simply wait for a cold to run its course, emerging evidence suggests that a basic household practice may help shorten that ordeal.
At a recent meeting of the European Respiratory Society (ERS), researchers highlighted new findings on nasal irrigation — the practice of rinsing the nasal passages with a sterile saltwater solution.
The technique is widely used to relieve congestion, but data presented by Professor Steve Cunningham of the University of Edinburgh indicates it may offer an additional benefit for young patients.

According to Cunningham, children who received a saline-based nasal treatment recovered from colds roughly two days sooner than those who were given standard care.
The research is still at an early stage, but scientists say the mechanism behind it is biologically plausible.
Cells in the nose rely on chloride, a component of common table salt, to generate substances that help block or limit viral activity. Increasing chloride in the nasal environment may, in theory, support that process and reduce the duration of symptoms.
For families considering the approach, clinicians stress that safety and technique matter.

Commercial saline sprays and pre-mixed solutions are widely available and considered safe when used as directed.
For homemade mixtures, however, using sterile or previously boiled water is essential. Public-health agencies warn that unsterilised tap water can contain organisms that pose serious risks if they enter the nasal passages.
Experts emphasise that nasal irrigation is not a cure and will not stop a cold immediately.
Still, as respiratory viruses circulate through schools, offices and public transport, it may offer a modest, low-cost way to ease discomfort and potentially recover a little faster.
