This form of asthma happens during physical activity when you breathe in air that’s drier than what’s in your body, and your airways narrow. It can affect people who don’t have asthma, too. You’ll notice symptoms within a few minutes after you start to exercise, and they might last...
Asthma induced by cold air and its relation to nonspecific bronchial responsiveness to methacholine. We compared bronchial responsiveness to isocapnic hyperventilation of cold dry air at -18 degrees C and 0% humidity with bronchial responsiveness to inhale... PM O'Byrne,G Ryan,M Morris,... - ...
Asthma is a very common respiratory condition. It is caused by inflammation in the lungs, particularly in the smaller airways (bronchioles) and air sacs (alveoli). While asthma is a chronic (long-term) condition, symptoms generally come and go, often varying in severity over time. What are ...
An asthma attack is a sudden worsening ofasthma symptomscaused by the tightening of muscles around your airways. This tightening is called a bronchospasm. During the asthma attack, the lining of the airways also becomes swollen or inflamed and thicker mucus -- more than normal -- is produced....
sensitivity of asthmatics to cold air has further been suggested by clinical provocation studies applyinghyperventilationand cold dry air[21], during exercise tests in cold weather[25]or when cold exposure has been combined with high altitude[26]. Wheezing, shortness of breath, cough and phlegm ...

Symptoms of asthma can be caused by triggers. Common asthma triggers include: tobacco smoke, dust mites,air pollution, pollen, mold, respiratory infections, physical activity, cold air and allergic reactions to some foods. Asthma diagnosis
Cold air challenge (CACh) has been shown to discriminate between children with asthma and healthy young children. Hyperventilation with dry room-temperature air is a simplified alternative. We compared responsiveness in young children with asthma between two standardized, single-step protocols: dry air...
and if these triggers can be identified and avoided, the likelihood of an attack decreases. Triggers can include: pollution, smoking, dust, animal hair, stress, pollen, exercise and cold air. These triggers are personal to each individual sufferer, so if you have asthma, make sure you know...
