What is a common sign of an asthma attack?

Rapid, shallow breathing is indeed a common sign of an asthma attack. When a person experiences an asthma attack, their airways become inflamed and constricted, making it difficult to breathe. As a result, individuals may instinctively breathe faster and more shallowly in an attempt to get more air into their lungs. This rapid breathing is a typical response to the feeling of breathlessness.

Persistent coughing can occur during an asthma attack as well; however, it is not as overtly visible as the rapid, shallow breathing that indicates immediate respiratory distress. Excessive sweating might be present due to stress or fear associated with the attack but is not a primary sign of asthma itself. Difficulty with vision is usually unrelated to asthma attacks and may indicate other medical issues. Therefore, rapid, shallow breathing is the most characteristic sign that points directly to an asthma attack.
