6 Health Myths Busted !

“Sitting Too Close to the Screen Will Ruin Your Eyes”
When TVs first became popular in the 1950s, they emitted 100,000 times more radiation than they do today, so parents may have been smart to keep their kids away from the tube back then. But sitting too close to a modern set or computer screen won’t do any permanent damage to your eyes. The fuzzy vision and headaches that follow a long day at the office are symptoms of eyestrain—a temporary condition no different from the soreness you feel after a workout. Relieve the aching with light massage around your eyes.

“Vitamin C Prevents Colds”

It’s true that if you don’t have enough C, you’ll get sick—but with scurvy, not a runny nose. if C could prevent one illness, the logic likely went, perhaps it could prevent others, too. But dozens of studies have found no difference in the number or duration of colds suffered by people who take C and those who don’t. What is the best way to stay cold-free? “Nothing beats hand washing,” .

“Jet Hand Dryers are More Sanitary Than Paper Towels”

Dryer or paper towel? It’s a confounding daily dilemma. Molecular biologist Keith Redway, of the University of Westminster, has done a series of experiments to put an end to the debate.

(You’d probably have to eat seven of them However, if a hot-milk nightcap seems to help you catch z‘s, drink up. A little placebo effect never hurt anyone.

“Hydrogen Peroxide is Good For Cleaning Wounds”

You know the fizzing that happens when the liquid touches your wound? It’s the sound of the chemical attacking germs, yes, and also your own cells.

The authors recommend washing your cuts gently with soap and water, then dabbing on a topical antibiotic.

“If Your Mucus Turns Green, Your Infection is Bacterial—and You Need Antibiotics”

Congratulations, nose-blowing sleuths! This adage is partially true: When you have an infection, your body sends white blood cells called neutrophils to fight the germs, and when an enzyme in the neutrophils mixes with the healthy cells in your nose, your mucus changes color.
