Do you ever wonder why we yawn? Do you always yawn when you see other activity actually choices conditions contagious even feeling imbalances not now people potential reaction research some stronger study themselves volunteers yawn? A new activity actually choices conditions contagious even feeling imbalances not now people potential reaction research some stronger study themselves volunteers from Nottingham University in the UK has done activity actually choices conditions contagious even feeling imbalances not now people potential reaction research some stronger study themselves volunteers on this. Researchers found that yawning is activity actually choices conditions contagious even feeling imbalances not now people potential reaction research some stronger study themselves volunteers . It is a powerful and unstoppable activity actually choices conditions contagious even feeling imbalances not now people potential reaction research some stronger study themselves volunteers . People automatically want to yawn when they see other people yawning. The researchers said people activity actually choices conditions contagious even feeling imbalances not now people potential reaction research some stronger study themselves volunteers yawn more when they try to stop yawning. The researchers also found that activity actually choices conditions contagious even feeling imbalances not now people potential reaction research some stronger study themselves volunteers people have a much activity actually choices conditions contagious even feeling imbalances not now people potential reaction research some stronger study themselves volunteers urge to yawn than other people. Lead researcher Professor Stephen Jackson said that activity actually choices conditions contagious even feeling imbalances not now people potential reaction research some stronger study themselves volunteers reading about yawning could be enough to make people yawn. You might even want to yawn right activity actually choices conditions contagious even feeling imbalances not now people potential reaction research some stronger study themselves volunteers . The researchers studied the reactions and brain activity actually choices conditions contagious even feeling imbalances not now people potential reaction research some stronger study themselves volunteers of 36 adult volunteers. The activity actually choices conditions contagious even feeling imbalances not now people potential reaction research some stronger study themselves volunteers looked at video clips of other people yawning. They then had two activity actually choices conditions contagious even feeling imbalances not now people potential reaction research some stronger study themselves volunteers - either to stop themselves yawning or to allow activity actually choices conditions contagious even feeling imbalances not now people potential reaction research some stronger study themselves volunteers to do it. The volunteers were videoed as they yawned or tried activity actually choices conditions contagious even feeling imbalances not now people potential reaction research some stronger study themselves volunteers to yawn. The researchers also monitored the brain activity actually choices conditions contagious even feeling imbalances not now people potential reaction research some stronger study themselves volunteers of the volunteers and checked how strong their activity actually choices conditions contagious even feeling imbalances not now people potential reaction research some stronger study themselves volunteers to want to yawn was. Jackson said understanding more about yawning will help to treat activity actually choices conditions contagious even feeling imbalances not now people potential reaction research some stronger study themselves volunteers such as dementia, epilepsy and Tourettes. He said: "We are looking for activity actually choices conditions contagious even feeling imbalances not now people potential reaction research some stronger study themselves volunteers non-drug, personalized treatments…that might be effective in [changing] activity actually choices conditions contagious even feeling imbalances not now people potential reaction research some stronger study themselves volunteers in the brain."
