Wildfires are often large, and can sometimes lead to widespread impacts on the land, and on the well-being of the population. The main health effects of wildfires are respiratory illnesses (especially among children, the elderly, individuals suffering from pre-existing illnesses, and smokers) and poor mental health (which can range from temporary disturbances to severe depression and post-traumatic stress disorder).
Wildfire smoke can affect everyone differently. Symptoms can range from being lightheaded to difficulty breathing.
When smoke in the air becomes too much to handle, the following are some recommendations on how to lessen the effects:
- Keep doors and windows closed and seal any large gaps.
- Avoid using any exhaust fans like the ones in the kitchen, bathroom and clothes dryer.
- Turn on air conditioner to recirculate the air in the home, use ceiling fans, or portable fans rather than taking air from the outdoors.
- Avoid indoor pollutants such as tobacco smoke, heating with wood, frying or boiling foods, burning candles and using paints/adhesives.
- Keep a 5-day supply of medication available.
- Have a supply of non-perishable groceries that do not require cooking.
- Limit time spent outdoors and avoid exertion.
- If you begin to experience symptoms of wildfire smoke, evacuate to cleaner air shelter or leave area; if safe to do so.
People with heart or lung disease, the elderly, children, and pregnant woman should be aware of the effects that wildfire smoke may present. The following are activities that should be considered to protect themselves:
- Limit time spent outdoors.
- Avoid physical exertion.
- People with asthma should consult with their doctor.
- Individuals who suffer from lung or heart disease and are experiencing the following symptoms should contact their health care provider: repeated coughing, shortness of breath or difficulty breathing, wheezing, chest tightness or pain, heart palpitations, nausea, unusual fatigue or lightheadedness.
