Yawn to stay alert!

 

 

Time has brought about a lot of changes and one of them will be seeing teachers in classes encouraging children to yawn, while in the class! This would be driven by the belief of psychologists that yawning makes the brain more alert to its surroundings, as it causes the rush of blood into the brain, which creates a cooling effect. As yawning is contagious, its spread literally works as a helping of refreshments! So a good amount of yawning in class, make for a bunch of very attentive kids!
