Ozone pollution, which is invisible, can irritate the respiratory system, reduce lung function, inflame and damage the lining of the lungs and the cilia, and cause structural damage of the lungs. Ozone pollution can also reduce the number and functioning ability of bacteria-destroying white blood cells. Ozone pollution can aggravate asthma and increase people’s susceptibility to respiratory illnesses like pneumonia and bronchitis. Symptoms to watch for when ozone is in the air include coughing, pain when taking a deep breath, and breathing difficulties, especially when active or exercising outdoors. But ozone damage can also occur without any noticeable signs.
