Bushfire Smoke Causing Health Hazards Across Australia
Bushfires are an annual occurrence in Australia, but the recent ones have been particularly bad. Bushfire smoke is a mixture of tiny particles and gases generated during combustion. It contains fine particulate matter, nitrogen oxides, carbon monoxide, and other pollutants. The presence of these pollutants in the air poses severe health hazards to those exposed to it for an extended time.
Effects of Bushfire Smoke
Bushfire smoke affects people in different ways, depending on their age, overall health, and the length of exposure. The primary health effects of bushfire smoke include:
1. Respiratory problems: Breathing in bushfire smoke can cause respiratory issues, such as wheezing, shortness of breath, coughing, and tightness in the chest. The smoke also affects people with pre-existing respiratory conditions such as asthma, chronic obstructive pulmonary disease (COPD), and emphysema.
2. Eye and nose irritation: The presence of fine particles in the smoke can irritate your nose, throat, and eyes leading to dryness, itchiness, and redness.
3. Cardiovascular problems: The smoke can also cause heart and cardiovascular problems. Fine particles in the smoke can easily penetrate the lungs and enter the bloodstream, causing inflammation in the vessels, increasing the risk of heart diseases.
4. Mental health issues: The smoke can cause stress, anxiety, and depression in people who have been exposed to it for an extended period. It has been found that people who were exposed to bushfire smoke had a significantly higher risk of developing anxiety and depression.
Who is at Risk?
Children, the elderly, pregnant women, and people with pre-existing medical conditions such as respiratory problems and heart diseases are at an increased risk of having serious health effects from the bushfire smoke. People who work outdoors, such as farmers and firefighters, are also exposed to the smoke and are at a higher risk.
What Can Be Done to Stay Safe?
1. Stay indoors: When the bushfire smoke is heavy, stay indoors and keep your windows and doors closed. Use air conditioning to keep the inside of your house cool and comfortable.
2. Wear a mask: Wear an N95 mask if you need to be outside. The mask will filter out the hazardous pollutants present in the smoke and protect you from breathing them.
3. Keep hydrated: Drink plenty of water to stay hydrated. The smoke can cause dehydration, and drinking water can help in removing the toxins from your body.
4. Avoid outdoor activities: Avoid outdoor activities such as jogging, cycling, and sports when the smoke is heavy.
5. Seek medical help: If you experience any health issues, such as breathing difficulties, coughing, and chest tightness, seek medical help immediately.
