As average temperatures rise, ozone levels will worsen. Heat waves and higher average temperatures may occur more frequently as the climate changes due to global warming. Current temperatures, heat waves and increased ozone air pollution are exactly the conditions that are likely to become more common as greenhouse gases build up in the atmosphere. We often become desensitized to the effects of ozone because they are so common and can slip up on us so quietly. Or we mistake them for allergies, asthma, or other maladies.
Awareness is key.
Sensitive individuals may wish to reduce or modify their outdoor activities, perhaps by doing them early in the morning before ozone builds up or in the evening when it dissipates. Ozone levels have become unhealthy for most people. People with respiratory problems or other risks should avoid prolonged outdoor exertion. Sensitive individuals should avoid outdoor activity entirely. Half of the healthy people who engage in moderate exercise will experience moderately reduced lung capacity and 10-15 percent will experience moderate to severe respiratory problems.
