Study finds saline nasal care reduces upper respiratory infections in children: Here’s how it works

Saline nasal care: In Indian households, this is a well-known solution to the common cold and nasal issues. Saline nasal care uses a saltwater (saline) solution, and it is generally used to flush, moisturize, and clear nasal passages.

However, a growing body of research is pointing to saline nasal care as a simple trick that helps kids bounce back faster from colds and other upper respiratory infections.


Here’s the thing: Cold hits babies and young kids all the time, and when it does, parents look for simple home remedies that could help with the cold and its consequences. Now, a big clinical study found that basic salt-water nose drops can shave two days off a child’s cold. Even better, these drops can help keep the virus from spreading to the rest of the family.

What the research says

One of the biggest studies on saline for kids, the ELVIS-Kids trial, presented at a European respiratory health congress, looked at 407 children under the age of six years old. For this study, some parents used homemade saltwater drops for their child’s cold, while others just stuck to the usual care. The kids with saline got better within a week — in about six days. Whereas the other kids took closer to eight days to get better.

Now, that’s a real difference. And that’s not all.

What’s more, families who used saline noticed fewer siblings or parents getting sick, suggesting that nasal saline might help limit the spread of viruses within households. Parents reported that their kids perked up faster and needed fewer extra medicines, too.

How does saline nasal care actually help

The idea is simple: you flush out your child’s nose with salt water, either as drops or a gentle spray. Here’s what that does:

• It helps clear out mucus, dust, and germs.
• It eases stuffy noses, so your child can breathe more easily.
• Salt also seems to help the lining of the nose fight off viruses and reduce swelling.

You can buy saline drops at the store, but you can also make them at home (just be sure to use safe water and the right recipe).

More than just a shorter cold

Saline care isn’t just about getting over colds quicker. Studies show that it helps with stuffiness, runny noses, and makes breathing through the nose easier. Kids using saline had less need for other decongestants, and some research even says they sleep better when their noses aren’t so blocked up.

Is it safe for kids?

For most kids, saline nasal drops or sprays are totally safe — as long as you use clean, sterile, or properly boiled (then cooled) water. Side effects are rare and usually just a little nose irritation or mild burning that goes away quickly. That’s why pediatricians often recommend saline as a first thing to try for little ones with stuffy noses — it’s low-risk, and you can use it as often as needed.

What we still don’t know

Not every study on saline is perfect. Many have been pretty small, and they don’t always agree on how much it helps with every symptom. Different methods and age groups can affect results. Researchers say we need bigger, better trials to know exactly how much saline helps stop the spread of colds or prevent worse problems. Still, the evidence so far says saline is a solid, safe add-on to the usual cold care, especially for mild infections.

A few tips for parents

Thinking about trying saline for your child?

Here’s what helps:

• Always use boiled (and cooled) or sterile water to mix with salt — never tap water.
• Talk to your child’s doctor about the right kind of saline and how to use it for your child’s age.
• Be gentle and take it slow, so your child stays calm and comfortable.

With these simple, homely hacks, you should see some improvement in a few days. If things get worse or don’t clear up, check with your doctor.
