10 True Old Wives’ Tales: Take 2

Turns out, we have a lot of wannabe detectives in our midst! Our last post on which old wives’ tales were in fact true got such a great response we figured we’d give you 10 more to add to your repertoire!

Read on to learn 10 more true old wives’ tales:

1. The Tale: Hot Tubs Lower Sperm Count

Turns out, taking a dip in a hot tub (or just taking a hot bath) can actually lower sperm count. In a three-year study conducted by researchers at the University of San Francisco, it was found that men who had previously wallowed in hot water for an hour or more experienced a 491% increase in sperm counts after switching to showers for three- to six-months. The science behind all of this? Guys’ little swimmers need cooler climes to develop, a fun fact that mother nature took into account when she designed the male anatomy the way she did!

2. The Tale: Feed a Cold, Starve a Fever

Like many old wives’ tales, there is an absolute ton of conflicting research, especially when it comes to matters regarding cold care. However, when it comes to the old adage “feed a cold, starve a fever,” you’re grandmother might actually be on to something! According to a study conducted by researchers at the Academic Medical Center in Amsterdam, test subjects who fasted overnight and were then given only water the next day demonstrated elevated levels of a compound known to fight infections linked to fevers. A control group who were given meals, meanwhile, experienced higher amounts of a compound thought to tackle viral infections such as colds. However, since the study was incredibly small – involving only six volunteers – we’d recommend that since both fevers and colds can cause fluid loss, drink plenty of liquids to prevent dehydration. And, if you’re up to eating, dig in!

3. The Tale: I Can Feel It in My Bones

If we had a dime for every time we’d heard an old person lament that they could feel the onset of snow/rain/a light drizzle in their bones, we’d…well, we’d be wealthy enough to have retired long ago! But, turns out, granny might have the chops for a post-retirement career as a meteorologist. In a study of 130 patients with osteoarthritis and rheumatoid arthritis conducted by researchers at the Instituto Poal de Reumatologia in Barcelona, it was determined that arthritic patients did actually experience increased joint pain when there was a drop in atmospheric pressure (which, in the weather forecasting community, is generally recognized as a sign of future precipitation.) Our verdict? Next time great uncle Eddy complains his knee is acting up, throw an umbrella in your bag!

4. The Tale: Fish is Good for Your Brain

Want to keep your brain as fit as the rest of your body? Then you’d better up your fish consumption, because a 2006 study by researchers at Tufts University in Boston found that people with the highest blood concentration of DHA (a fatty acid found in many varieties of fish) had a 50% reduction in their risk of developing dementia or Alzheimer’s disease. If you’re a lost cause but you’d like your children to be braniacs, take heed of a recent study by folks at the National Institute of Health that suggests that children born to mothers who ate more fish and other seafood while pregnant were smarter and had better developmental skills than their peers born to mothers who ate less or none. As such, current American Heart Association guidelines recommend two servings of fish per week for optimum health. For best results, opt for low-mercury varieties – which is particularly important for pregnant women as surplus mercury can harm the developing fetus – such as shrimp, wild salmon or catfish and/or add a high-quality fish oil supplement.

5. The Tale: Cranberry Juice Prevents Urinary Tract Infections

When a UTI hits, most people would drink (or do) just about anything to get rid of the pain. And now, there’s proof that cranberry juice might actually work. According to a study by Israeli researchers, cranberry juice (and blueberry juice too!) inhibits a type of bacteria commonly associated with infections by clinging to the walls of the bladder and creating a teflon-like coating that is inpenetrable to UTI-causing bacteria. A follow-up study published in the Canadian Journal of Urology in 2002, meanwhile, showed that those who drank three cups of cranberry juice daily for one year experienced one fewer UTI than their peers in the placebo group.

6. The Tale: Long Labor Means a Boy

Of all the old wives’ tales, those surrounding pregnancy are perhaps the most popular (and perhaps the most widely disputed!). However, according to a study conducted at Dublin’s National Maternity Hospital of 8,075 births, the gem about a long labor being a sign of a baby boy just might be true! According to the study, births of male infants were significantly more likely to require oxytocin augmentation, fetal blood sampling (an indication of fetal distress), forceps delivery or Caesarean section. While the researchers acknowledge that male infants typically have larger head circumferences than their female counterparts, they note that this factor “would not fully explain the sex difference.” Commenting on the study findings, the researchers note that “when we say ‘it must be a boy’ as a humorous explanation of complications of labor and delivery we are scientifically more correct than previously supposed.”

7. The Tale: Wrap Up Warm to Stave Off a Cold

Again, another old wives’ tale that is founded on some pretty contradictory research. Until recently, it was widely believed that your mothers’ assertions that wrapping up warm would stave off a cold were actually – scientifically proven to be – incorrect. However, a 2005 study conducted by researchers at the University of Cardiff in Wales found that participants who had their feet dunked in a bucket of cold water were twice as likely to catch a cold as those who were not dunked. Reflecting on these findings, the researchers speculate that the cold temperatures may have restricted circulation, which in turn decreases germ-fighting immune cells, leaving you more susceptible to a cold. It should be noted, however, that even the researchers who conducted this study felt that more research was necessary to prove the theory!

8. The Tale: Swimming Within an Hour of Eating Will Give You Cramps

According to the Winnipeg Regional Health Authority, this one might actually be true. You see, after a meal, blood is diverted to the digestive tract to help assist with the digestive process. Exercise, on the other hand, also causes blood diversions. So, it makes sense that if you’re digesting food while exercising vigorously, not as much blood would be available for the muscles, resulting in cramps. How to gage whether you’re swim ready? If you can honestly say that after eating that meal, you’d be comfortable going for a light jog around the neighborhood, you will most likely be fine in the pool!

9. The Tale: Shaving Your Legs Makes the Hair Grow in Thicker and Coarser

A favorite saying of mothers desperate to prevent their young daughters from taking a razor to their legs, this one might actually be true (on a technicality). According to dermatologists, natural hair tapers at the end, whereas hair that is cut with a razor is cut across its midshaft, giving it a thicker appearance and courser texture. Is the hair actually thicker? Well no, but if you continue to always cut the hair at its midshaft, the stubble will always appear coarser and will also contrast more against the color of the skin.

And finally, just for fun:

10. Holding a Knife or Axe During an Eclipse Will Result in Injury

Uhh…duh. It seems entirely plausible that a person wielding a sharp implement in pitch darkness could hurt themselves (or, as various slasher flicks would lead us to believe) someone else!

  1. Ah, the old, “warm bathtub” wives tale. I remember when I was little and my old Nana used to give me a bath, and she always said, “Little Jayson, if you stay in that tub too long, you’ll lower your sperm count!” Nana was full of these crazy tales from the old country, I never believed her.

  2. I was always told that I would not be able to gain a full erection and I would have a low sperm count if I were to be in hot tubs. I was also told that hot tubs are really, really dirty.

  3. I was also told that hot tubs are really, really dirty.

    This can be absolutely true for communal hot tubs if the people responsible for keeping it clean don’t keep up with it. My wife has worked at a fitness center for many years, and she used to be the one responsible for cleaning tubs in both locker rooms. She was happy when they finally got rid of the one in the men’s locker room because she said we (meaning us guys) were hard to clean up after.

  4. Vitamin pills ‘increase risk of early death’

    Have your say Read comments

    Popular vitamin supplements taken by millions of people in the hope of improving their health may do no good and could increase the risk of a premature death, researchers report today.

    Vitamin pills are no substitute for healthy diet
    Have your say: Do we rely on vitamins too much
    They warn healthy people who take antioxidant supplements, including vitamins A and E, to try to keep diseases such as cancer at bay that they are interfering with their natural body defences and may be increasing their risk of an early death by up to 16 per cent.

    Antioxidants, including vitamins A, E, and C are said to mop up free radicals, which cause disease

    Researchers at Copenhagen University carried out a review of 67 studies on 230,000 healthy people and found “no convincing evidence” that any of the antioxidants helped to prolong life expectancy. But some “increased mortality”.

    About 12 million Britons supplement their diets with vitamins and the industry is worth £330 million. But little research has been done on the long-term health implications.

    The Department of Health said yesterday that people should try to get the vitamins they need by eating a balanced diet and advised care in taking large doses of supplements.

    A spokesman said: “There is a need to exercise caution in the use of high doses of purified supplements of vitamins, including antioxidant vitamins, and minerals. Their impact on long-term health may not have been fully established and they cannot be assumed to be without risk.

    advertisement”Anyone concerned about their diet should speak to their doctor or dietitian.”

    Antioxidants, including vitamins A, E, C and beta-carotene and selenium, are said to mop up compounds, called free radicals, which cause disease. It is this action that researchers believe may cause problems with the defence system.

    The Danish research, released by the influential Cochrane Library, applied only to synthetic supplements and not to vitamins that occur naturally in vegetables and fruit.

    It found that vitamin A supplements increased the risk of death in healthy people by 16 per cent. Taking beta-carotene was linked to a 7 per cent increased risk, while regular users of vitamin E supplements increased the risk of an early death by four per cent.

    Although the review found no significant detrimental effect caused by vitamin C, it found no evidence that it helped ward off disease. Millions take it in the hope of avoiding a common cold.

    Goran Bjelakovic, who led the review, said: “We could find no evidence to support taking antioxidant supplements to reduce the risk of dying earlier in healthy people or patients with various diseases.

    “If anything, people in trial groups given the antioxidants beta-carotene, vitamin A, and vitamin E showed increased rates of mortality.”

    But Patrick Holford, a nutritionist who has formulated supplements for the company Biocare, said: “Antioxidants are not meant to be magic bullets and should not be expected to undo a lifetime of unhealthy habits.

    “When used properly, in combination with a healthy diet full of fruit and vegetables, getting plenty of exercise and not smoking, antioxidant supplements can play an important role in maintaining and promoting overall health.”

    A spokesman for the Health Supplements Information Service said: “People should get all the vitamins and minerals they need from their diet, but for the millions who are not able to do that, vitamins can be a useful supplement and they should not stop taking them.”

    However, Catherine Collins, of the British Dietetic Association, said: “This study is deeply worrying and shows that there should be more regulation for vitamins and minerals.

    “The public can buy vitamins as easily as sweets. They should be treated in the same way as paracetamol with maximum limits on the dosage.”

  5. I knew it about the feed a cold/starve a fever thing!! My body just naturally does that anyhow. When I just have a head cold, I’m still hungry. But throw in a fever and I don’t even want to think about food. Funny how smart our bodies are!

    And long labor = boy? News to me! Did they say what they were comparing it to though? Were they comparing first-time mothers? Were they comparing the mothers’ reports of previous pregnancies? Interesting.

    PS> I’m going to stop shaving my legs now. When my husband complains – I’m sending him your way;)
