Do you want to gain better control over your asthma? Put it in writing! By following the examples below, you can use a journal to track day-to-day changes in your asthma. This may be something you can do with a parent's or guardian's help. If your parent or guardian has asthma, he or she can also use a journal to track his or her own symptoms, too.
Make copies of this page before you write on it so you can use it again!
Check the boxes below to show when you had symptoms.
This is a measure of how well your lungs are working. Below, write down your peak-flow numbers for the green (doing well), yellow (getting worse), and red (medical alert) zones.

Green: Your peak flow is more than _________
Yellow: Your peak flow is between _________ and ______________
