Introduction to yawning
Yawning is a universal phenomenon that occurs in humans and many other animals. It is a reflexive action characterized by opening one's mouth wide and inhaling deeply, often followed by a subsequent exhalation. Yawning is commonly associated with feelings of tiredness, boredom, or drowsiness. However, the science behind yawning is much more complex than simply indicating a need for sleep.
