How to Prevent Fainting
*** begin quote ***
Syncope, otherwise known as fainting, is the sudden, brief loss of consciousness caused by diminished blood flow to our brain; that occurs at least once in about one in five people, and in about one in ten may happen over and over, responsible for millions of emergency room visits and hospitalizations. Though sometimes fainting can be caused by heart problems, most often it’s triggered just by standing (because blood pools in our legs) or strong emotions, which are called vasovagal reactions. Under certain circumstances, such as blood donation, syncope has important medical and societal significance. More than 150,000 people experience fainting spells or near-fainting spells each year when they’re giving blood. So, it would be good to find a way to avoid it. But, if you think that has medical and societal significance, what about fainting when you’re driving? It goes without saying that losing consciousness while driving can pose a serious threat to the patient and society. Of a group of folks getting tested for it, 9% reported they had lost consciousness while driving.

Is there anything we can do to prevent the symptoms in the first place? Do we have to wait until we’re all dizzy, clammy, and nauseous? Well, speaking of cheap, safe, and effective, just drinking water can prevent it. So, if you know needles make you whoozy, five minutes before you get stuck, chug down two cups of water, which can dramatically bring pressures up within minutes in people who are predisposed to fainting, and has similar effects in normal healthy adults.

I’m astonished. I never knew this. While I never had any trouble donating, I’ll keep this in mind.

“So, if you know needles make you whoozy, five minutes before you get stuck, chug down two cups of water, which can dramatically bring pressures up within minutes in people who are predisposed to fainting, and has similar effects in normal healthy adults.”
Water eh? I always KNEW DHMO was deadly! Whew… I think I’ll go have a smoke instead: I believe it has a “similar effect(s) in normal healthy adults.”
Heh. actually, there’s a study out there about secondhand smoke and blood pressure in children, and the researchers and headlines went ballistic about “high blood pressure” being visited upon children as young as 8 years old that way.
Of course once you actually READ the research instead of the press release, you’ll find that not only are they only talking about brief increases of about a single blood pressure point, but they also found that the effect only held true for boys. In the girl population, the stats showed an even larger effect: supposedly REDUCING their blood pressure by about a point and a half.
The researchers’ reaction to this inconvenient fact? The main researcher noted that the girls’ pressure reductions were also “a cause for alarm!” Anyone think that if it were found that an apple a day slightly lowered kids’ blood pressure by a point or two that it would be called “a cause for alarm!”? LOL!
You’ll actually get a much stronger “heart damage measure” for blood chemistry if you let your little Johnnies ‘n Janies eat a bowl of cornflakes with milk in the morning. Seriously! Here’s what I said about it in TobakkoNacht:
“It’s clear that on the basis of the likely results, Killer Kornflakes Consumption beats out ETS Exposure by a country mile in terms of posing a deadly threat to our children. Cornflakes should not be sold to children. They should not be sold to child abusers posing as responsible parents who feed them to innocent children. They should not be displayed openly in stores. They should not be associated with brightly smiling cartoon characters and healthy sports figures. Boxes should be a drab muddy green with 80% of the remaining packaging devoted to full-color pictures of putrescent bloated corpses, fat-oozing arteries, and bloody bursting hearts! The base $4 price of a box of flakes should be slapped with a tobacco-style tax of 400% to make a carton of Tony The Tiger ring in at a nice, child-safe $20. And finally, any film portraying cornflakes or their paraphernalia (bowls, spoons, milk, etc.) should be slammed not just with an R rating but with a full-blown X.
Giannini’s research may soon bring headlines blaring the warning, “A Few Flakes of Corn May Harm Your Heart.”
Unless someone’s been lying to us about the deadly threat of casual ETS exposure.”
Ahh welll… apologies. Got sidetracked by that “Water increasing Blood Pressure” thing.
