New Delhi, November 13, 2025 – The e-Paper edition of The Hindu tackles a common phenomenon: contagious yawning. In today’s “Question Corner,” the publication explores the science behind why seeing someone yawn, even in a picture, can trigger the same reaction in others.
The article highlights two leading theories. The first posits that yawning is a form of social mirroring. Our brains, attuned to mimic others, activate similar muscle groups when we see or hear a yawn. This might have evolved to synchronize arousal and alertness within groups.
The second theory suggests a physiological role. Yawning may help cool the brain by boosting blood and air flow through the sinuses. This would explain why susceptibility to yawning is influenced by factors like temperature, tiredness, and mental alertness.
The article further notes that people who pay less attention to social cues, such as young children and some autistic individuals, are less prone to contagious yawning. Likewise, those in cooler environments or actively engaging their jaws through talking or chewing may suppress the urge.
The Hindu’s “Question Corner” continues its mission of exploring everyday phenomena through the lens of science, engaging readers with accessible and informative content. The Hindu e-paper offers a variety of topics, including “The View From India”, “First Day First Show”, “Today’s Cache”, “Science For All”, “Data Point”, “Health Matters”, and “The Hindu on Books.”
