Children are more susceptible to airborne particles, such as pollens and dust, than adults. Kids have smaller airways and breathe faster than adults, allowing them to process air more rapidly. Kids are also more prone to allergies that aren't as common in adults, such as food allergies.
Repeated exposure to allergens and airborne chemicals can cause a child's lungs to develop more slowly than normal and can sometimes limit lung growth, making the child prone to chronic lung diseases throughout life.
For children with asthma, allergies can make life even more miserable. Consult your physician or the Allergy and Asthma Center at Hasbro Children's Hospital for more information about helping your child live with allergies, asthma or both.
