Acting Director Mid North Coast Local Health District Greg Bell said the region's air quality had deteriorated in recent weeks due to the prevalence of bushfires and prevailing weather conditions.
He said that while this doesn't necessarily result in increased hospital presentations, it can exacerbate symptoms of people in higher risk groups - particularly in areas where smoke has been present for several months or where bushfires are still burning.
"We very strongly advise people who are more sensitive to smoke, including those with chronic respiratory or cardiac conditions, pregnant women and very young children, to take active steps to protect their health," Mr Bell said.
"Residents are advised to stay indoors in air conditioned buildings until the air clears and avoid strenuous exercise or heavy outdoor work, where possible.
"Symptoms can occur for several days after smoke is inhaled, so people with chronic respiratory and cardiac conditions need to be vigilant with their own medication or treatment programs. If symptoms do not settle, contact your doctor."
Fine smoke particles affect the human respiratory system and can aggravate existing chronic health conditions by penetrating deep into the lungs and entering the blood system.
"Smoke exposure can lead people with lung disease or chronic bronchitis to develop shortness of breath, coughing or wheezing, many days after smoke is inhaled," he said.
"We recommend these people closely monitor their symptoms and follow their asthma or Chronic Obstructive Pulmonary Disease (COPD) action plan."
In the event of an emergency, always remember to dial Triple Zero (000).
Healthy adults may also feel the effects of fine particles that can irritate the lungs. They may need to adjust intensity and time of exercise but generally any symptoms will clear after the smoke disappears.

* In answer to another question about air quality monitoring, or lack thereof, in the region, the Guardian News was told NSW Health is not responsible for this and that it falls under the jurisdiction of the Department of Planning, Industry and Environment (DPIE).
DPIE is reportedly considering establishing an air quality monitoring station on the North Coast given the significant population growth of the region.
The Guardian News will confirm this as soon as it has a response.
