What I want to know

Why do I yawn when I see someone else yawn?

Re:What I want to know

[Bonker]

A doctor once told me that most yawns (not all) were a sign that you had high levels of C02 building up in your bloodstream. (Thus, it happens more often when you're sleepy and not moving around much) Yawning slowly expels most the gas from your lungs and causes you to deeply inhale, hopefully getting more oxygen than carbon dioxide in the mix.

Seeing another person yawn triggers the desire in you to yawn for the very real purpose of getting rid of your excess C02 as well. This may be because we know that if one of us is getting sleepy or deprived of oxygen we all are, or if one of us is in a location that is prone to oxygen depletion-- the bottom of a cave or burrow, for example-- then we need to move to an area that is more open to moving air.

Humans have a lot of responses like this. When one of us gets sick and vomits, anyone else who sees it also feels sick and tries to vomit. The implication being that if one of us has eaten bad, possibly toxic food, the rest of us should try to purge our stomachs before it affects us.

Try this the next time you're at home with your dog or cat. Yawn widely and deeply in front of your pet. Chances are, you can make your pet yawn. This is an old, *old* mechanism.

I know I'm yawning just thinking about it.

Babies

[dmorin]

My baby was hiccuping the day she was born. The doctor said that hiccups in babies are very common and not the same frustrating thing they are in adults. On the contrary it's the cutest darned thing since the little darling never stops staring at you all the while hiccuping like a crazy person. (As a new parent you learn to distinguish the cute harmless hiccups from the ..ahem...juicier sounding ones that signify you'd better get yourself a burp cloth in a hurry.)

The doctor also said that they have no clue why it happens, and that at least one study had shown that if you bring a baby out into bright light they will often start hiccuping. I keep pointing my daughter at the sun, but so far, nuthin. :)

This has only failed me once in the last ten years. YMMV.

1. Get a glass of water.
2. Take a deep breath and let it out, but don't push it out. Don't worry if you hiccup during that breath.
3. Without taking another breath, start taking *tiny* sips of the water; try to take at least one per second. Swallow each one. Keep your epiglottis closed as much as you can, in case you hiccup in the middle of doing this.
4. After 10-15 sips, the muscles in your mouth and throat will start to get tired, making it more difficult to do this. Keep going.
5. After a few more sips you won't care about the tired muscles, because you'll really REALLY want to breathe. Force yourself to take a couple more sips, then stop drinking and take that breath.

You should have no more hiccups after this. If you keep hiccuping wait a few minutes and try again. If it doesn't work on the second try, you're screwed. Also, this will not work if the hiccups are from being drunk and it may not work if they're a side-effect of medication.

Photopic sneeze

[LondonLawyer]

There's a problem for fighter pilots called photopic sneeze which affects them when they are suddenly hit in the eyes with bright sunlight and can cause loss of control at high speeds. Interesting that some guy here mentions a drinking buddy who used to both sneeze and hiccough when out drinking. Wonder how closely these two spasmodic reflexes are linked.
