The Science and Benefits of Yawning
Yawning is not just a sign of sleepiness it is also linked to brain function and social behavior. Studies show that contagious yawning may be related to empathy, as humans and some animals, like dogs and primates, yawn more when they see others yawn. Yawning can also help stretch the jaw muscles and increase blood flow to the brain, temporarily improving focus and alertness. While yawning is a common and harmless activity, excessive yawning may indicate fatigue, stress, or underlying health conditions. Regardless of its exact purpose, yawning remains an intriguing and universal human behavior. Shutdown123
