We may have learned a one or two urban legends about health but what’s wrong is that we choose to believe they’re true. Here are some of the health rumors we’ve learned about our ancestors and the truth.
1. It’s okay to observe the five-second rule with food
There shouldn’t be any five-second rule. “Eating dropped food poses a risk for ingestion of bacteria and subsequent gastrointestinal disease, and the time the food sits on the floor does not change the risk,” said Roy M. Gulick, M.D. , chief of the division of infectious diseases at Weill Cornell Medical College. It’s true that if bacteria is present, it will cling to the food immediately on contact. But still, it’s safer to toss it in the trash.
2. People only use 10 percent of their brain.
We are using 100 percent of our brain. Why? Because studies suggests that damaging just a part of our brain can cause huge damage.
3. Plucking gray hair will double the growth.
If you have an errant hair, it’s fine to tweeze it. Having gray hair has something to do mostly with genetics. When there is hair fall, it usually takes 6 months for it to grow back. As part of the aging process, you will automatically see more gray hair.
4. Breast cancer is largely genetic.
Only 5 to 10 percent of women diagnosed with breast cancer are due to genes. Even if you have a family history, it still is not due to specific genes mutations. The American Cancer society says that cancer is a combination of lifestyle factors and genetic susceptibility.
5. Catch a cold from being outside too long.
Going outside with our without a wet head is the best way for you to prevent catching a cold. Generally, colds are caused when you stay more often indoors, especially when you’re in close contact with everyone. Thus, spending time outdoors will actually help you less likely to catch a cold.
6. Cats steal air from a baby’s mouth.
It’s anatomically impossible for a cat or other animal to suffocate a baby by sealing the infant’s mouth with its own. There’s no problem with keeping a pet while the baby is here.
Still, it’s a good idea to supervise pets around babies and small children — for the kitty’s safety just as much as the child’s.
7. Antiperspirant deodorants cause breast cancer.
Even if you opt for natural products, it doesn’t guarantee that you will not get breast cancer. Antiperspirants have aluminium, which is often a false positive finding in a mammogram. Before breast screening, you should skip the white part. According to the National Cancer Institute, there are no links that it causes breast cancer.
8. Cracking your knuckles causes arthritis.
Contrary to what most people believe, cracking your knuckles won’t do any harm for your joints. Studies suggest that there’s no significant difference between people who crack their knuckles and those who didn’t. However, people who do often have weaker grips.
9. Drinking cold water after meals can lead to cancer.
Drinking water is a healthy practice may it be hot or cold. The theory is that cold water helps solidify oily fats from your meal into a “sludge” that lines the intestines and can lead to cancer. Still, there’s zero evidence from medical literature to support this theory.
10. Chewing gum takes seven years to pass through your digestive tract.
The body can’t digest chewing gum but it doesn’t just sit on your stomach. You eliminate it when you go to the bathroom just like other food you haven’t digested.
