(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.
