If I Yawn, Does That Mean I Am Tired?
Yawning is a common occurrence and a typical symptom of fatigue. However yawning could also point to a serious health problem.
Key takeaways:
· Yawning is contagious and there will be involuntary imitations once you see someone else yawn.
· Yawning flexes the walls of the sinus cavity and helps to regulate brain temperature.
· Excessive yawning may indicate the presence of a disease such as Parkinson’s or multiple sclerosis or an impending epileptic fit.
Because it is linked to actions such as muscle stretching, joint movement, and an increased heart rate (think early morning waking), yawning may be part of the body’s way of gearing up for activity.
