Sydney’s recent heat waves are alerting people with respiratory conditions to take caution.

According to the NSW Office of Environment and Heritage, Sydney has experienced poor air quality due to high ozone levels. 

Combination of heat waves, car exhaust and industrial fumes worsen the ozone pollution. 

“Ozone levels are higher outdoors than indoors, so parents should limit the time their children with asthma play outside as they are more susceptible to the effects of ozone pollution,” the Director of Environmental Health Branch Dr Ben Scalley said. 

The direct link between high temperatures and ozone pollution reveal that ozone levels are the lowest in the morning. Sydneysiders are urged to plan outdoor play in the morning, when the temperature is lower. 

Asthmatic people are also recommended to carry their reliever at all times, as the air quality worsens. 

“Asthma sufferers need to follow their Asthma Action Plan and take their relieving medication when necessary. If symptoms get worse, asthma sufferers need to seek medical advice,” Dr Scalley added. 
People can receive air quality alerts and hourly air quality updates via SMS or email. They can also visit the Office of Environment and Heritage website and subscribe to Air Quality Index daily forecasts.
