*OMG, if you’re anything like me, you’re still pissed that all those carrots you eat do absolutely nothing to help your failing eyesight. And the next time you see some kid cracking his or her knuckles, just let ’em be, if they do get arthritis (or girls end up having hands that look like a boys’) it probably won’t be because of anything they did – besides, hopefully, live to grow old. But all is not lost, (and I’m sure our parents didn’t intentionally lie to us) because at least six of the old urban legends actually turn out to be legit.
Aren’t you excited?
By now many of us have had plenty of experience testing the things our relatives said would happen if we did this or didn’t do that. The abundant opportunities we have encountered in our daily lives over the years have either helped us to dispelled the myths immediately, or give it a fair run – only to realize it was as far from truth as anything could possibly get.
Channeling that experience now, would you agree that these 6 urban myths really are true?
Here’s the first according to MSN,
1. Yawning is contagious.
Research in monkeys, dogs, and humans has proved if one person yawns, so do those around him, says Steven Scharf, M.D., PhD., director of the University of Maryland Sleep Disorders Center. But the reason is as mysterious as the phenomenon. One possibility: Yawning increases alertness, so some speculate it’s contagious to help synchronize members of a group to be alert to the possibility of threats, Dr. Scharf says.
2. Want to get rid of those hiccups? Have someone scare you.
Hiccups happen when your diaphragm muscles and controlling nerves get stuck in a “reflex arc,” where the nerves keep signaling the diaphragm to contract suddenly—causing your hiccup—and then triggering it to repeat itself, says Rachel Vreeman, M.D., M.S., coauthor of Don’t Cross Your Eyes … They’ll Get Stuck That Way! And 75 Other Health Myths Debunked. This reflex usually ends on its own, but something that interrupts the loop—like being startled enough to gasp—can sometimes make the hiccups stop sooner, she adds.
And this one was down right disconcerting for some, I’ll bet.
3. A cold shower can shake your urge for sex.
Not only will the shock of cold water provide an effective distraction, but the temperature also helps lower your heart rate, says Men’s Health urology advisor Larry Lipshultz, M.D. The cold causes your blood vessels to narrow—known as vasoconstriction—which in turn, restricts the flow of blood to all extremities, including the penis.
