More Dangerous Than Drinking and Driving


Article Source: Health And Fitness Journal

Epidemiological studies of auto accidents have suggested that cell phone usage quadruples the risk of getting involved in a crash. Up might think that all conversations should be equally distracting, but this isn’t the case — passengers may actually improve the performance of the people driving them about. A new study examines the reasons for this.

There are at least three aspects of driving that appear to be negatively impacted by cell phone use. First, drivers on cell phones have a pronounced tendency to drift out of their lane. Second, it becomes more difficult to adjust to the cars around you on the road. Finally, drivers engaged in cell phone conversations are bad at strategic or task-focused processes, such as actually getting to their intended destination.

The new study used a highly sophisticated driving system called PatrolSim that’s designed for training police officers. The tests were run on a simulated freeway, where the participants had to exit to a rest area. For live conversation, the authors recruited pairs of friends and asked them to discuss a “close call” situation, where one of them narrowly averted a life-threatening situation.

The study’s authors noted that compared to having a passenger, cell phone use made drivers’ lane discipline worse, and doubled the rate at which drivers missed the intended exit. When the authors examined the conversation videos, some reasons for this difference became clear. Passengers frequently turned the conversation towards a discussion of traffic conditions and often noted when the relevant exit sign appeared. When a passenger was present, the pace of conversation also dropped as traffic increased, and participants often started using less complex language.

10 Dangerous Everyday Things in Your Home


Article Source: Health And Fitness Journal

Household consumer products injure 33.1 million people in the United States every year. These incidents cost $800 billion in related expenses from death, injury or property damages. And many scientists are starting to believe that, in particular, the chemicals found in a wide variety of the goods you use every day may be more toxic than previously thought. Here are 10 of the most common products that may be hazardous to your health:

10. Mothballs

Since moths chew holes through clothing and other textiles, people pack away these stinky repellents to kill them. But studies on one active ingredient in some repellents, paradichlorobenzene, found that it can cause cancer in animals. Other types of moth balls use naphthalene, which after prolonged exposure can damage or destroy red blood cells, and which can also stimulate nausea, vomiting and diarrhea.

9. Pesticides

Ninety percent of households in the United States use some form of pesticide, a broad term that encompasses a variety of chemical formulas that kill everything from tiny microorganisms up to rodents. In 2006, the American Association of Poison Control Centers received nearly 46,000 calls regarding children under 5 years old who had been exposed to potentially toxic levels of pesticides.

8. Pressed Wood Products

This faux wood takes bits and pieces of logs and wood leftovers and combines them together. Pressed wood products include paneling, particle board, fiberboard and insulation, all of which were particularly popular for home construction in the 1970’s. However, the glue that holds the wood particles in place may use urea-formaldehyde as a resin. The U.S. EPA estimates that this is the largest source of formaldehyde emissions indoors. Formaldehyde exposure can set off watery eyes, burning eyes and throat, difficulty breathing and asthma attacks. Scientists also know that it can cause cancer in animals. The risk is greater with older pressed wood products, since newer ones are better regulated.

7. Chemicals in Carpets

­Indoor carpeting has recently come under greater scrutiny because of the volatile organic compounds (VOCs) associated with new carpet installation. The glue and dyes used with carpeting are known to emit VOCs, which can be harmful to your health in high concentrations. However, the initial VOC emissions will often subside after the first few days following.

6. Laser Printers Chemicals

­­A 2007 study found that some laser printers give off ultra fine particles that can cause serious health problems. Another study confirmed that laser and ink-jet printers can release volatile organic compounds (VOCs) and ozone particulates. All of these have been linked with heart and lung disease.

5. Lead Paint

­In 1991, the U.S. government declared lead to be the greatest environmental threat to children. Even low concentrations can cause problems with your central nervous system, brain, blood cells and kidneys. It’s particularly threatening for fetuses, babies and children, because of potential developmental disorders. Many houses built before 1978 contain lead paint. Once the paint begins to peel away will, it release the harmful lead particles that you can inhale.

4. Air Fresheners and Cleaning Solutions

­Air fresheners and cleaning solutions, when used excessively or in a small, unventilated area, can release toxic levels of pollutants. This comes from two main chemicals called ethylene-based glycol ethers and terpenes. While the EPA regards the ethers as toxic by themselves, the non-toxic terpenes can react with ozone in the air to form a poisonous combination. Air fresheners in particular are linked to many volatile organic compounds, such as nitrogen dioxide, and some fresheners also contain paradichlorobenzene, the same chemical emitted by mothballs.

3. Baby Bottles and BPA

Canada has taken the first steps to outlaw the sale of baby bottles made from polycarbonate plastics, which are the most common type on the market. It has done so because the plastics are made with a chemical called bisphenol-a (BPA). BPA has a structure very similar to estrogen and for that reason is referred to as a “hormone disruptor.” Hormone disruptors can interfere with the natural human hormones, especially for young children.

2. Flame Retardants

Commonly used in mattresses, upholstery, television and computer casings and circuit boards, flame retardants use polybrominated diphenyl ethers, or PBDEs for short. Two forms of PBDEs were phased out of use in manufacturing in the United States in 2004 because of related health threats, but the products containing them linger on. Studies have linked PBDEs to learning and memory problems, lowered sperm counts and poor thyroid functioning in rats and mice. Other animal studies have indicated that PBDEs could be carcinogenic in humans, although that has not yet been confirmed.

1. Cosmetic Phthalates

Phthalates, also called plasticizers, go into many products including hair spray, shampoos, fragrances, and deodorants. Phthalates bind the color and fragrance in cosmetic products, and are also used to increase the durability and flexibility of plastics. Like BPA, these hormone-like chemicals are linked to reproductive and developmental problems in animals. Because of these findings, California and Washington state have banned the use of phthalates in toys for younger children.

Healthy Baby Dies After MMR Vaccination


Article Source: Health And Fitness Journal

George Fisher, aged 18 months, was a healthy and robust baby, but he died just ten days after being given an injection of MMR vaccine. He had earlier suffered a fever fit which can be aggravated by the vaccine.

The infant was discovered dead in his cot in Cheltenham, Gloucestershire by his mother Sarah Fisher just hours after he was heard “chatting away on the baby monitor”, a coroner was told.

Mrs. Fisher and her husband Christopher believe the vaccine is “implicated” in their son’s death. The temperature-raising effects of the drug on children who have suffered febrile convulsions were not explained to them.

Two doctors confirmed that giving MMR to children like George, who contracted the fever four months earlier, was permitted under patient guidelines.
