Yawning is a contagious behaviour that occurs when we see someone else yawning, although the exact source is unknown.
Mirror neurons, which fire when we perform or see others, may be involved in contagious yawning, enabling us to mimic their actions.
Additionally, contagious yawning can improve social relationships by indicating group participation and mutual concern for one another.
Yawning can serve as a type of empathy, subtly conveying feelings of weariness or boredom and allowing us to share their perspective.
To prevent contagious yawning, avoid gazing at others and cover your mouth to limit airflow and the possibility of others yawning.
