(HealthDay News) -- Everyone yawns.

But yawning too much could signal a larger medical issue.

To help your doctor pinpoint why you yawn so much, the University of Maryland Medical Center says you should track the following factors in a log:

• When you first noticed that you were yawning, and how often you yawn.
• The time of day that you yawn a lot, including after certain activities (such as eating or exercising).
• Any locations that seem to trigger your yawning.
• What seems to increase your yawning, such as insufficient sleep, changes in activity, medications or boredom.
• Anything that helps your yawning improve.
• Any other symptoms that accompany yawning.
