Can You Get An STD From A Toilet Seat?

Public toilets are not exactly paragons of cleanliness, but they're not as 'dirty' as you might suspect!

OK, here's the deal: You can get cooties, and THAT'S about it. The idea that you could get an STD from a toilet seat "sounds believable," but is highly unlikely. Hard surfaces such as toilet seats are NOT conducive to STDs. Sexually transmitted diseases are spread via sexual intercourse with an infected person. Most are spread more easily from men to their partners. The diseases vary in how infectious they are, but NONE are spread on toilet seats....well, assuming you're using the toilet seat for what it was intended...Many of the organisms that cause STDs can't survive outside the human body for long, and need a particular environment in which to thrive. Viruses start to die immediately once they leave the skin of an infected person. Incidentally, there's a rumor that the toilet seat myth got started by men who wanted their wives to think a public restroom, not their mates' adulterous ways, had given them an STD.More »

Do men really think about sex every 7 seconds? Watch this video to get the truth behind this sexy story.

Men think about sex every 7 seconds, right? Mmmm, not quite. By most accounts, the extent of men's lustful imaginings is more humdrum. Assuming the average male is awake for 16 hours a day, this would mean that a man thinks about sex more than 57,600 times a day. Someone thinking about sex THAT often would simply be incapable of performing any other tasks at all, and would likely drive himself insane. The origin of the 7-second statistic, a favorite of glossy magazines, is a mystery. The Kinsey Institute suggests that 54% of men think about sex AT LEAST every day, 43% think about it a few times a week, and 4% once a month or less. All men are different though; some WILL think about sex many times daily. And sexually experienced men are reported to fantasize more, perhaps because they have a richer repertoire of material from which to pluck their scenarios.More »

How clean is your dog's mouth? Cleaner than yours? Find out what kind and how many germs are finding their way to your dog's mouth.

Here is the myth that makes dogs sound like a dental miracle: despite all the leftover tuna sandwiches, coffee-ground strewn garbage and rancid chicken bones they chew, our canine friends STILL maintain better oral hygiene than humans do, despite how carefully we floss and brush our teeth. Could this really be true? In a word, NO. The myth that a dog's mouth is clean most likely stems from their practice of licking their wounds. What that tongue is actually doing is ridding the wound of dead tissue. A dog's mouth is besieged by its own legions of germs, roughly as huge in population as those living in the human mouth. And, as we all know, dogs aren't particularly fussy about where they put their tongues. "A dog's mouth contains a lot of bacteria," confirms veterinarian Dr. Gary "Ask the Vet" Clemons. "Remember, a dog's tongue is not only his wash cloth but also his toilet paper."More »

People have believed that we use only 10% of our brains for more than 100 years. Unfortunately, all that means is that people have been wrong for MORE than 100 years. This is probably one of the most oft-repeated factoids about the brain, in part because it's been endlessly publicized in the media. Here's the thing, though; it's NOT true. Brain scans show that the vast majority of the brain does NOT lie fallow. For any given activity, like eating, walking, kissing, or reading naughty novels, you use a few specific parts of your brain. So where did the myth come from? Many sources point to an American psychologist from the early1900s, named William James, who said: "the average person rarely achieves but a small portion of his or her potential. "Many sources point to an American psychologist from the early1900s, named William James, who said: "the average person rarely achieves but a small portion of his or her potential."

No, knuckle cracking and arthritis are not related. But that does not mean it's safe to crack your knuckles, as it could lead to other problems. Find out more in this video.

Crack. Pop. Click. These sounds jump from the joints of those in the habit of cracking their knuckles. Depending on your point of view, knuckle-popping sounds disgusting or cool. But there's NO evidence that it inflames the joints or leads to arthritis. Located between two bones, the knuckles are bathed in synovial fluid, which lubricates the joints. Sometimes, a bubble of gas forms in this fluid, and when the knuckles are cracked, it breaks the adhesive seal in the joint, and we hear: Pop! The arthritis connection may be an old wives' tale, but cracking your knuckles CAN hurt your hand in other ways, and there's NO benefit to it. Instead, try bending and stretching your fingers a few times to relieve tightness. And keep in mind, that while cracking your knuckles may seem like an innocent, mindless habit, for the person next to you, it may be just as irritating as the sound of fingernails on a chalkboard.More »

How likely is it that you'll catch a cold directly from cold weather? We've all heard that this is possible, but is it really? Watch this video for more information.

No. Being cold does not directly give you a cold, but it CAN weaken your immune system. Also, when it's cold OUTSIDE, people tend to stay INSIDE, where air circulation is sub-optimal. You come into closer contact with the people aound you-which CAN increase the likelihood that you will catch a cold. Colds are caused by viruses, and you can get the virus through inhaling infected air droplets sneezed or coughed by an infected person, or by touching something that an infected person has touched and then transferring the germs to your mouth or nose. With over 200 different types of cold viruses in any given season, you can potentially catch many different variants of the cold. BUT, you don''t get it from cold air, slush, wind, or other wintry conditions. So what's the best way to ward off this miserable virus? Wash your hands often.More »

Like surface-to-air missiles, antibacterial soap just SOUNDS more destructive than old-fashioned soap. Thing is, the germs don't know the difference. Consumer-grade antibacterial soaps are no better at removing more bacteria or preventing infection symptoms-like coughing, sneezing, diarrhea-than plain soap. And the trouble is, it can also breed "super bugs" that our bodies-and antibiotics-can't fight. Furthermore, the soaps, most of which contain the antimicrobial triclosan, produced worrisome antibiotic cross-resistance among different species of bacteria, according to a study published recently in Clinical Infectious Diseases. The conclusion? Stick to plain, old soap and water. If you want to commit germicide with regular soap, take your TIME. The CDC recommends scrubbing for AT LEAST 15 seconds. And pay particular attention to the area under and around your fingernails as this is where most bacteria tend to reside. So heed the call, and lather, rinse, repeat, to get YOUR hands as bacteria-free as possible!More »

Midnight snacks are fun, but do they make you gain weight? Watch this video to learn if eating at night makes you fat.

While eating late at night has been associated with obesity, midnight munching does not CAUSE obesity. A potbelly is the result of too many calories OVERALL, not just the results of late-night snacks. "The time of day a person eats is not as important for overall weight gain as the amount of calories eaten during the day," says a spokesperson for the American Dietetic Association. Late-night eating CAN lead to extra poundage. But it's NOT because of the time of day, it's because eating late at night is likely to involve ALCOHOL and SOCIALIZING...two factors that often lead us to over-eat. And eating in this state tends to be MINDLESS munching, of calorie-rich foods. Whether or not you gain weight is simple: if you take more calories in than you expend, then weight you will gain. It's about how MUCH you eat, not so much about WHEN you eat. Weight gain and eating late...busted!More »

If you wait after eating to go swimming, are you less likely to drown. Probably not. Check out this video to find out why.

No one has ever drowned because they went swimming with a full tummy. While it MIGHT make you uncomfortable, it WON'T cause you to drown. While there's theoretical cause for concern, since the body diverts circulation of blood to the gut-and away from the muscles-which COULD cause a cramp, it's not a real threat. And even if you did get a cramp, in most cases, you could easily exit the water before any real damage is done. alcohol use, lack of safety gear on boats, and lack of protective fencing and covers for pools. Taking some time to digest makes sense, but FAILING to do so is NOT the enormous danger about which we're often warned. However, ALWAYS listen to signals from YOUR body-if you experience pain, severe fatigue or cramping when swimming, go park yourself on your towel, and wait till you feel better, before jumping back in.More »

If you've recently stopped working out regulary, you might worry that your muscle can turn to fat. But is this true? Find out the truth in this video.

Maybe this myth was started by the marketing department of a health club chain. People often worry that once they stop regularly working out, their muscle will become fat. But muscle CANNOT turn into fat, because they're made of two very different types of cells. People get fat when they stop working out, because they continue to eat the same amount of food, but burn off fewer calories. As a result, their unused muscles grow soft while they simultaneously gain excess body fat. If you stop exercising, you'll still have the same NUMBER of muscle cells-but each will get thinner. If you continue to eat the same amount of food, *the fat cells, which were already there, will expand. This is the basic weight gain equation: if your "calories in" are greater than your "calories out," then your fat cells will begin to bloat and gloat. But under no circumstances will your muscle cells morph to fat cells.More »

Coffee Stunts Children's Growth: Myth or Fact? Get the truth about how coffee does and doesn't effect children in this health video.

Besides the jitteriness and the insomnia, children have another reason not to drink coffee: it stunts their growth. Or so was once thought, according to an old wives' tale. But after decades of research on the physiological results of coffee consumption, there's no evidence that it has ANY effect on height. The genesis of this myth is unclear. Caffeine consumption was thought to be a factor in osteoporosis, which stemmed from early studies associating high intake of caffeinated beverages with reduced bone mass. Much of the research, however, that linked caffeine and osteoporosis, was conducted in populations that ALSO had low calcium intakes, a DEFINITE culprit of reduced bone health. The minor effect that caffeine MAY have on calcium absorption is easily mitigated by adding a few tablespoons of milk into your coffee. If coffee doesn't stunt children's growth, should you still limit their consumption? Perhaps, if you don't want caffeine-induced mania driving you mildly insane!More »

Sometimes people stay away from medical care because they fear what they might find. And a lump in the breast can be a scary thing indeed, but guess what: 8 out of 10 breast lumps are BENIGN! Sometimes lumps are caused by cysts, nipple discharges and calcifications, which can result from hormonal changes, infection, injury or bruising. This percentage tends to fluctuate with age. For young women, more than 80% of breast lumps are benign, as women age, the risk for breast cancer increases, which means that the percentage of benign breast lumps in older women may be much lower than in younger women. Take charge of your health by performing routine breast self-exams, establishing ongoing communication with your doctor, and scheduling regular mammograms. If YOU discover a persistent lump in your breast or any changes in breast tissue, it's VERY IMPORTANT that you see a doctor immediately, because catching cancer early SIGNIFICANTLY increases the chances of recovery.More »

Having healthy levels of Vitamin D is vital to your overall health. But is spending time outdoors the best ways to absorb vitamin D? Check out this video for more information on Vitamin D and the outdoors.

Vitamin D, often referred to as the 'sunshine" vitamin-since sunlight is the best source-is key to sustaining long-term health. Prevailing wisdom has been that we get sufficient amounts of Vitamin D from our everyday exposure to sun, but recent research has found that this is NOT the case. Basically, your body cannot make Vitamin D, but you CAN get it from food and sunlight. Unfortunately, you cannot rely on diet alone to supply enough vitamin D. Exposure to sunlight is the key to producing ample amounts of this essential vitamin. But don't take this as license to bake yourself to a crisp in the sun. Generally, your body will produce adequate amounts of vitamin D with 20-30 minutes of sun exposure on your hands, arms and face everyday-but here's the rub, sunscreen dramatically inhibits UV ray penetration, which is necessary for Vitamin D production, so go out with some of your skin sunscreen-free, and then apply after 20-30 minutes have passed.More »
