CORAL SPRINGS, FL -- Fire officials encouraged Coral Springs and Parkland residents with respiratory problems to stay indoors on Tuesday as a result of lingering fires in the Everglades.

Coral Springs-Parkland Fire Department confirmed with Florida Forest Service that there is sugar cane burning in the Everglades.

The fires don’t pose a threat to Coral Springs and Parkland, fire officials said.

But for those with chronic heart and lung diseases, persistent smoke from a fire can cause headaches, sore throat, a runny nose, and tiredness, according to the Centers for Disease Control and Prevention. The biggest health threat from smoke is from microscopic particles, which can penetrate deep into your lungs.
