Recently, we published evidence that cells use the chloride from salt to fight viral infections. Also, nasal irrigation with salt water helped reduce the cold in adults. Hence, we are now testing if salt water nose drops helps children fight the cold.
If you have a child under 7 years of age, you may be able to join the fight.
The Children’s Hospital in Edinburgh are doing a study of salt water nose drops to see if it helps get rid of the cold faster.
Your child does not need to have a cold right now to take part!
You can join right now by calling/texting 07973657457 for an appointment to sign up and to be taught what to do the next time your child has a cold.
Your child does not need to attend.
Families completing the study will receive travel expenses and a £30 voucher to compensate for any inconvenience.
