📌 NEW RESEARCH ALERT for Parents of Young Children
A recent randomized trial found that using hypertonic saline (about 2.6% salt-water) nasal drops in kids up to 6 years old with a common cold reduced symptom duration from ~8 days to ~6 days — that’s two fewer days of sniffles, coughing and general misery. 
📋 Key Findings:
• 407 children enrolled; 301 developed colds.
• In the treatment group: parents made & applied 3 drops per nostril, at least four times per day, until well. 
• Fewer household family members caught the cold when the child used the nasal drops (46% vs. 61% in usual-care group). 
• The mechanism: extra chloride from the salt solution helps nose & airway lining cells make more hypochlorous acid, which can suppress viral replication. 
• The intervention is cheap, simple and appears safe when done under guidance. 
✅ What this means for your family:
Consider discussing with your provider whether saline nasal drops could be a safe adjunct tool when your child catches a cold. While it’s not a cure or a substitute for other recommended care (hydration, rest, monitoring for complications), it may help your child recover a bit more quickly and reduce spread to siblings.
🚨 When to call us instead of doing home-care alone:
• Your child has difficulty breathing, high or persistent fever, signs of dehydration, or worsening after initial improvement.
• Symptoms are unusually severe or lasting much longer than a typical cold.
• You’re unsure about using nasal drops (e.g., the child has allergy, asthma, or nasal/anatomical issues).
Using hypertonic saline nasal drops can reduce the length of the common cold in children by two days, according to a study that will be presented at the European Respiratory Society (ERS) Congress in Vienna, Austria. They can also reduce the onward transmission of colds to family members.
