Asthma is a disease that causes inflammation of the airways of the lungs and results in narrowing of the airways. Wheezing and coughing, chest tightness, and shortness of breath are some symptoms of those suffering from asthma or Allergies. Both conditions have a genetic component and children with at least one biological parent with a history of asthma or allergies are more likely to have a diagnosis of either one or both of these conditions. The three preventative measures below may prevent or delay one or both conditions.Dust MitesPreventing asthma or allergies begin with removing airborne substances and dust mites. This is especially true for infants and children already suffering with asthma or allergies. Protect bedding and pillows by using zippered allergen impermeable covers. Additionally, wash all bedding linen at least once a week in hot water. Improve air quality by keeping humidity below 50%, and installing a household humidifier with thermostat control helps to maintain comfortable moisture levels. Lastly, keep upholstered furniture and carpeting out of an infant's bedroom.PetsCats and dogs are cuddly; however, they can trigger an asthma attack or make allergies worse in children. According to the American Academy of Allergy Asthma and Immunology, there is conflicting research whether pet exposure strengthens or weakens the immune system. Make sure pets are free of excess hair to keep pet dander at a minimum. Use a bagless vacuum cleaner or one with a HEPA filter to remove dander from carpets.Tobacco UseAs a precaution, do not expose children to smoke before or after birth especially during pregnancy. Smoking while pregnant, significantly increases wheezing and coughing during infancy. After smoking, wash hands before picking up a child. Confined spaces like car cabins are another place to avoid exposing children to secondhand smoke, and do not allow passengers to smoke. Maintain healthy air quality by not smoking indoors.Whether a child is asthmatic or suffers from allergies, make sure to schedule regular visits to a pediatrician. If necessary, follow up with an asthma specialist.
