Big Yawn

Does my yawn make you want to yawn too? 

Why do we yawn? 

Usually, it happens when we are sleepy or tired.

It can also happen when we are bored. 

I read about some experiments that showed people and animals yawn more in cooler weather than in hot weather. Do you yawn more in cold weather than in hot weather?
