Do you ever wonder why we yawn? A new study from Nottingham University in the UK has

done research on this. Researchers found that yawning is contagious which means spreading or affecting others. It is impossible to stop this reaction. People automatically want to yawn when they see other people yawning. The researchers said people actually yawn more when they try to stop yawning. Even reading about yawning could be enough to make people yawn. You might even want to yawn right now. The researchers studied the reactions and brain activity of 36 adult volunteers. The volunteers looked at video clips o f other people yawning. They had two choices: either to stop themselves yawning or to allow themselves to do it. The volunteers were videoed as they yawned or tried not to yawn. The researchers also monitored the brain activity of the volunteers and checked how strong their feelings to want to yawn were. Understanding more about yawning will help to treat some diseases.
