Emotional stress, panic and anxiety also may trigger an attack in certain individuals. Responses to emotional situations, such as laughing, crying or yelling, involve deep, rapid breathing that can trigger an attack. Deep, rapid breathing during exercise also can trigger an asthma attack. Though breathing may become difficult and uncomfortable, exercise still benefits an asthmatic's overall health. By taking proper steps to avoid an attack, most asthmatics can fully participate in physical activities.
Studies show that breathing cold air can lead to the swelling of airways.
Other weather conditions, such as wind and rain, also create problems. Wind distributes pollen and other allergens into the air and rain can increase pollen and mold levels. Asthma is a reversible pulmonary disease, in that the airway constriction is a result of exposure to an allergen. Bronchitis is also a pulmonary disease but is not reversible. Over time, it results in progressive tissue damage and airway constriction.
