What health condition can be aggravated by ground-level ozone?

Ground-level ozone is a harmful air pollutant that can significantly affect respiratory health. It is known to aggravate existing lung conditions, particularly asthma. When someone with asthma is exposed to ground-level ozone, they may experience heightened symptoms such as shortness of breath, wheezing, and coughing. The ozone can cause inflammation and irritation in the airways, making it more difficult for individuals with asthma to breathe and manage their condition effectively.

Although allergies, hypertension, and diabetes are important health concerns, they do not have a direct association with ground-level ozone in the same way that asthma does. Allergies might be influenced by pollutants, but ground-level ozone is specifically known for worsening asthma symptoms, which is why it is the most accurate answer.
