Smoke is made up of a complex mixture of gases and fine particles produced when wood and other organic matter burn. These particles can cause burning eyes, runny nose, coughing, a scratchy throat, irritated sinuses and headaches.
Use common sense. If it looks smoky outside, it's probably not a good time to mow the lawn or go for a run. It's probably also not a good time for children to play outside. When smoke is heavy, avoid prolonged or heavy exertion. Remain indoors. Keeps windows and doors closed, temperature permitting. Keep your indoor air as clean as possible. Avoid using gas stoves or candles indoors. Dust masks are ineffective against smoke. If you have asthma, lung or heart disease and your symptoms worsen, call your doctor.
