Mothers and doctors have long noted increases in asthma symptoms at times of stress. The easiest situation to describe and understand is the asthma that occurs with crying. Crying increases the rate and depth of breathing, and the asthma that occurs in this situation is similar to asthma caused by exercise. However, asthma symptoms also increase when there are other kinds of stress, such as excitement, anger, or even laughing. The physiological reasons that asthma increases under these situations is not clearly understood.
Children learn a lot about dealing with stress by watching the adults in their lives.
So, the issue is minimizing stress and teaching your child how to deal with stressful situations when they occur. It is helpful to be consistent with expectations and discipline. Understanding expectations and knowing the limits will decrease stress. All children need love and praise for meeting expectations and not exceeding the limits. Schedule some fun but non-stressful activities for the family.
