Is yawning contagious?You can not stop yawning?  

I yawn when I have a headache. I mean I will yawn every 5 minutes. My grandma says that it's because it brings oxygen to the brain and the reason I have a headache may be not enough oxygen. I also yawn when others do. I think everyone does. It's something psychological. Same with hiccups. Only the first hiccup is real. The rest are just your brain repeating it's self.

It's really weird, and something I would like to know an explanation to, why yawning is so contagious

I yawn in all kinds of situations, like when I am bored or when I am tired. Even reading this discussion has given me the urge to yawn

This is so true with me and yawning. I hate to have someone around me yawning. I can't stop and I get all tire and sleepy. I even get mad if it is one of my friend who is doing it. I don't like to constantly yawn till tears are coming out of my eyes.

Hi, icesmile. I have yawned when others would yawn too. It would make me feel very sleepy. I think it has an effect on someone that is tired that does not look tired. When I am very sleepy, my eyes do tend to water some. It has been like this for many years for me. I usually yawn when I am tired and sleepy. I never yawn just to be yawning.

I really do think that yawning is contagious. I find that the times I yawn is when I am bored with something or someone. The other times I would just be tired from not having enough sleep the night before. I think I remember seeing on the news that if someone else yawns you are more likely to yawn too. I know it does sound kinda weird.

Hello ice,
I have heard once from my friend that yawning is contagious.So I observed if it is really contagious.And I notice that it really is.Everytime I saw someone yawning, it make me yawn as well.I am not sure why was that.It makes me sleepy too if I see someone yawning.

Hi, is contagious,and is unvoluntary too. I know that a yawn is a reflex of inhalation and exhalation that draws more oxygen into the bloodstream.
the doctors say that is our body needs to have more oxygen , so is a sign that blood, and in special brain need more oxygen.
But yawning is associated with boredom and sleeping from people.

Yawning is always contagious or so it is for me, Every time I see, hear, or even think of someone yawning I will end up yawning just like I am right now..twice since starting to respond..lol Funny how that happens..I yawn more when tired or bored then any other time..

Hi there Ice Smile. There have been studies last years about yawning and about the fact that there are about 78% chances of another person yawning when he sees one doing so. I personally believe that there is a chance of over 90% of yawning when you see a person doing so, especially in the morning when you are in the subway and people look like they would rather be at home sleeping than here.

Yawning is explained medically as a reason for leveling the pressure in the head (if i remember correctly) so it is perfectly fine to do so.

Reading the word yawn made me yawn. It is very contagious. If someone in a group of people start yawning, you can watch how it spreads in high speed. Tears come out when I yawn. Yawning starts when I'm bored and sleepy too.
