The heat is affecting everyone but especially the millions of Americans living with the chronic lung condition, asthma.
Doctors say there are steps asthmatics can take to manage their condition.
- You should stay indoors with the windows shut -- to avoid pollutants like smoke, dirt and gasses.
- Stay in air conditioning -- because fans can actually blow allergens.
- And when possible, avoid outdoor activity.
- If you do go outdoors -- like for work- take breaks.
But experts say the best advice is to take medications regularly and have rescue medication on hand.
