The elevated ozone levels pose significant health risks, particularly for sensitive groups, including young children, older adults, and individuals with asthma, bronchitis, or other respiratory and heart conditions. Exposure to high ozone concentrations can lead to throat irritation, chest pain, and inflammation of the lungs. Long-term exposure may reduce lung function. Residents in the Eastern Zone, South Central Bay, and Santa Clara Valley are advised to avoid strenuous outdoor activities during the afternoon and early evening when ozone levels are highest.
