Tight, hoarse throat; trouble swallowing Swelling of the tongue, affecting the ability to talk or breathe Weak pulse Pale or blue coloring of skin Dizziness or feeling faint Anaphylaxisa potentially life-threatening reaction that can impair breathing and send the body into shock; reactions may simultaneously affect different parts of the body for example, a stomachache accompanied by a rash Most food-related symptoms occur within two hours of ingestion; often they start within minutes. In some very rare cases, the reaction may be delayed by four to six hours or even longer. Delayed reactions are most typically seen in children who develop eczema as a symptom of food allergy and in people with a rare allergy to red meat caused by the bite of a lone star tick.

ANd it's kind of pointless, so I'd rather have it taken out. Wrong explanation is wrong explanation[ edit ] The mechanism suggested above cannot be right. It does not explain why fainting occurs within seconds after hyperventilation.

If supression of the breathing reflex was all that was happening, then the practitioner would still need to hold his breath for a couple of minutes to pass out. Isn't there an M. Yes, you are right, even 'though I wrote that, there is another step involved and I have now added it.

I have always been aware that this mechanism is much more complicated than previously stated but have never gotten around to articulating what is actually happening. The fact that it is so complicated is what makes it so dangerous, I have enough trouble communicating the shallow water blackout mechanism, I don't know if you can get this one across.

Hypocapnia changes your whole body chemistry, its behind this, behind diving accidents and high altitude disease. The actual mecahanism is self-induced hypocapnia via hyperventilation depressing CO2 levels and thus supressing the urge to breathe.

The squeeze is a schoolboy red-herring and just serves as the inducement to breath hold in a hypocapnic state. The mechanism is properly described under shallow water blackout.

It has nothing whatever to do with stopping and releasing blood. In our day the breathhold was induced by a bear hug, actually you can do it all by yourself by hyperventilating and just holding your breath. Misunderstanding the mechanism stops kids from avoiding hyperventilation to extend dive times.

The real mechanism is rather subtle and probably not understood by most teachers either so its not surprising that the blood surge idea got a hold.

I am happy to edit sometime if no major objections but it will be a big edit. I've never heard of pressing on the heart; I don't see how that would work. I don't really see a twelve-year-old kid being able to exert enough pressure on a rib cage to have any effect on the heart. I disagree about the squeeze being a red herring, though.

Maybe the bear hug is, but the method that uses carotid pressure is certainly not. You can make someone pass out by squeezing the carotid even without the hyperventilation part like in a sleeper hold.

The hyperventilation just makes it work faster. It's really not similar at all to shallow water blackout; that method doesn't even require holding your breath when pressure is exerted. I'm taking out the part explaining the method of "squeezing the heart area" because it doesn't make sense and is largely irrelevant these kids aren't dying giving each other bear hugs; they're strangling themselves, so it's obvious which method they're using.

I'm going to put a link to shallow water blackouts in the "see also" section. I think that should be sufficient. There are a number of dangerous children's games, perhaps we should handle them all under either a directory called "Dangerous children's games" of an article heading and then discuss each one seperately so the Choking game would only involve stragulation.

We also need to be careful not to end up encouraging kids to try this stuff. I disagree for two reasons. First, the adjective "dangerous" denotes a certain point of view.

Three to four deep breaths before breath-hold diving has long been generally recommended and is usually not considered as hyperventilation. As you point out, you get most of the benefit from the increased oxygen stores in the lungs from a couple of deep breaths.
