Why do we tend to yawn so much when working with a computer?

By gildalit

Opening our mouths in a wide yawn while staring at the computer screen. Does that sound familiar to you? Don’t be ashamed, you’re in good company. This is a phenomenon almost each and everyone of us experiences. It’s a bit uncomfortable when others at work, and worse even, our boss, stares at us yawning. So, What causes yawning and how can we prevent it?
There are many theories that try to explain why do we yawn, for example:
Yawning is related to boredom, fatigue, discomfort, crowded areas, lack of fresh air etc.
Yawning is intended to increase oxygen delivery to the brain.
Yawn is designed to cool the brain and make us stay awake.
But the yawning phenomenon is actually related to a bunch of other reasons, such as: poor sleeping quality, sleep deprivation (lack of sleeping hours), nutrition, lighting, ventilation, air conditioning etc.
I would like to introduce another, mostly unknown, reason – those pertaining to ergonomics – namely, not implementing the right ergonomic rules.

As an ergonomic consultant I run into a lot of computer users, who simply cannot stop yawning. I’m certain that a study looking into the relation of yawn frequency to work productivity level will uncover some interesting findings.
One of the most important goals of an ergonomic consultant is to make employees feel more comfortable in their working station. Correct work station arrangement and spacing plus stretching exercises can certainly improve employees feeling, reducing yawns and improving productivity.
So, dear employers, if you’re looking to increase the work productivity you are getting from your employees, you should invest in ergonomic consulting, make sure you have spacious work stations, consult with your ergonomics specialist on lighting and air conditioning.
The benefit you would reap will offset immensely any cost you pay.

The Ergonomics of Computer Gaming

More and more doctors recommend that you use the Wii gaming console as a tool for physical exercise  and up keep of a healthy lifestyle.
Does this idea have merits? I’m not so sure.
In many homes today, computers and televisions are used as the parents babysitter and lifesaver. When kids get bored, it is just too easy to tell them to go watch TV or play on the computer.
On the other hand, many parents are becoming aware of the physical deterioration caused by prolonged sitting in front of a computer or television and their conscience is working overtime!
However, recently it seemed a solution to this quandary has been found. Parents talk about it enthusiastically  – “I bought the kids a Wii console and we are really pleased, it’s a win win situation – the kids are absorbed into this new activity and are busy and quiet, plus they’re actually physically active in a way even doctors recommend”.
I, for one, did not buy my children the Wii, and surprisingly, they’ve never asked me to do so.
The truth to be told is that my children love real life activity, like riding a bike outside, playing tennis on a real tennis court, they enjoy basketball and soccer, playing catch with their friends… generally, they prefer being outside rather than inside the house.
In my opinion, children playing Wii get too used to the convenience of home, to the sweetened drinks and sweets accompanying play time. They lose the ability to orient themselves in space, they lose range of motion, physical interaction and physical contact gained in playing with other children. They miss out on learning and improving the different timing perception of ball delivery, kick, and body balance acquired when playing outside, and suffer a loss of the sensory capability acquired outside the home. Yes, even the ability of dealing with the elements and some inclement weather is lost to them.
I agree that there are some health benefits to playing Wii but they can not be at all compared favorably to games held in the open, fresh air outside. In fact, the most dangerous thing is that those games become a permanent substitute for real life active games and supply us parents with the illusion that we can, in good conscience, allow our children to sit at the computer again.
