Ancient Egyptian mummies reveal the evidence for air pollution

In the recent researches made scientist have found the evidence deposit of some particulates in the lungs. The particulates are related much with lung disease, heart disease, lung cancer, lung ailments. They are tiny microscopic particles which cause high disturbance to the lungs. These particulates play as an evidence to prove that the mummies may […]

7 Thoughts That Are Bad For You

Our personalities do more for us than determine our social circles. Temperament can impact a person’s physical health.

“The idea that behavior or personality traits can influence health is one that’s been around for a long time. We’re just now getting a handle on to what extent they do,” said Stephen Boyle of Duke University Medical Center in North Carolina.

From those with a chill demeanor to the completely frazzled types, mental factors are ultimately tied to physical health. And while a highly neurotic person might deteriorate more quickly than others, not every character trait will kill you. Some might even boost lifetimes.

1 Cynicism

Cynics who tend to be suspicious and mistrustful of others, a character trait that scientists refer to as hostility, may have an increased likelihood of developing heart disease. “These aren’t necessarily hot-headed people, but people who are more likely to read into people’s behavior as some hostile motive,” Stephen Boyle said during a telephone interview.

In a study of more than 300 Vietnam veterans who were healthy at the study start, Boyle found that those who scored high on measures of hostility were about 25 percent more likely to develop heart disease.

Boyle and his colleagues think that hostile individuals might experience more stress, which can cause spikes in an immune-system protein called C3 that has been linked with various diseases, including diabetes. In fact, the participants with higher scores on hostility showed an increase in these proteins while the non-hostile men showed no such increase.

2 Lack of Meaning

If you lack a sense of purpose, your stay on Earth could be truncated. A study involving more than 1,200 elderly participants who didn’t have dementia at the study’s start found that those who indicated having a high purpose in life were about half as likely to die over the study period, which lasted up to five years. The results, published in the June 15 issue of the journal Psychosomatic Medicine, held regardless of a person’s age, sex, education and race, along with level of depression and neuroticism.

“Persons with high purpose readily derive meaning from and make sense of the events of their lives, and likely engage in behaviors and activities that they deem important,” said study researcher Patricia Boyle of the Rush Alzheimer’s Disease Center in Chicago.

Some other research has suggested that people with a higher sense of purpose may have different levels of stress hormones, better heart health or improved immune systems, though more research is needed to firm up any of these biological mechanisms, she said.

The opposite also holds: “The findings from our study suggested that people who no longer set and work actively toward goals or enjoy their day-to-day activities (how they spend their time) are those with greater mortality risk,” Boyle told.

3 Fretting

People who are highly neurotic — constantly worried and anxious, and prone to depression — die sooner on average than their chill counterparts. And a recently reported study of nearly 1,800 men followed over a 30-year period suggests that’s partly because neurotics are also more likely to smoke. Perhaps having a cigarette eases anxiety, said study researcher Daniel Mroczek of Purdue University in Indiana, adding that such a short-term payoff might not be worth it if it kills you down the line.

4 Lack of Self-control

Late for appointments? Can’t keep your desk organized? No self-control? These seemingly benign qualities could take a toll on your health.

A review of more than 20 studies and nearly 9,000 participants revealed people who are conscientious — organized and self-disciplined, as opposed to impulsive — live two to four years longer than others. Study researcher Howard S. Friedman of the University of California, Riverside, suspects the boost in lifetime can be attributed partly to the fact that highly conscientious individuals are less likely to smoke or drink to excess, and live more stable and less stressful lives. The study is detailed in a 2008 issue of the journal Health Psychology.

The jitters can put a strain on your noggin, research suggests. Compared with the highly frazzled, individuals with a mellow demeanor who are outgoing may be less likely to develop dementia, which can be caused by Alzheimer’s disease and other illnesses. The claim is based on a study that followed more than 500 elderly individuals for five years. Among the outgoing extroverts, dementia risk was 50 percent lower for participants who were calm compared with those who were prone to distress.

6 Gloom and Doom

The gloomy, inhibited person is not just at a disadvantage socially, but also physically.

A preliminary study of more than 180 patients suffering from peripheral arterial disease (plaque buildup in the arteries) showed participants with so-called type D, or distressed, personality, had an increased odds of dying sooner than other people. Type-D people are more likely to experience negative emotions while at the same time hold in their feelings.

The researchers, who detail their work in the August issue of the journal Archives of Surgery, suggest the personality type is linked with the body’s immune system as well as stress response system.

7 Stre
ss

Whatever you do, don’t let this list worry you! Research is showing that prolonged stress can be deadly, and if it doesn’t do you in, workplace stress can increase your chances of heart disease, flu virus, metabolic syndrome and having high blood pressure.

A study of nearly 700 Israeli workers found that those who experienced job burnout (when work stress becomes unmanageable) were nearly twice as likely as others to develop type 2 diabetes, in which a person’s body becomes resistant to the sugar-regulating hormone called insulin.

And while a job promotion might boost your income, it also stresses you out. British researchers recently found that when people get promoted, they suffer on average about 10 percent more mental strain and are less likely to find time to go to the doctor.

High cholesterol? Try a splash of rapeseed oil on your salad

Adding rapeseed oil to the diet may lower the cholesterol and blood fat levels of patients who have had high cholesterol from birth.

The metabolic condition, known as familial hypercholesterolemia, affects around 60,000 Britons. It can lead to an increased risk of developing atherosclerosis or furring up of the arteries, and heart disease.

The oil can cut levels of bad cholesterol and triglycerides – blood fat levels – by up to 29 per cent after just five months.

In an Austrian trial, children aged six to 18 with the condition ate a classic low-fat, lowcholesterol diet enriched with the oil. In the first two months they took an average of 15g a day, going up to 22g a day for the last three months.

Rapeseed oil contains half the saturated fat of oils such as olive oil.

It is also high in unsaturated fats, which helps reduce cholesterol levels.

• Drinking at least three cups of tea every day could improve the life expectancy of people with heart disease.

In a study at Harvard University, researchers found that drinking two or more cups of tea a day was linked to a 44 per cent lower risk of premature death in patients who’d suffered a heart attack.

It’s thought that tea – specifically compounds called polyphenols – has a beneficial effect on the lining of the arteries. In a new trial, researchers will use MRI scans of tea drinkers and non-tea drinkers to assess any changes in the state of their arteries.

Drinking milk 'cuts risk of dying from heart disease and stroke by one fifth'

Drinking milk could cut your chances of dying from heart disease and stroke, say scientists. 

Contrary to reports that milk harms health, they claim consumption could reduce the risk of succumbing to chronic illness by as much as a fifth. 

Scientists at Reading and Cardiff universities reviewed 324 studies on the effects of milk consumption. 
 

Healthy stuff: Drinking just a third of a pint of milk daily can benefit health

They found milk protects against developing most diseases, apart from prostate cancer, and can cut deaths from illnesses by 15 to 20 per cent. 

Reading University’s Professor Ian Givens said milk had more to offer than just building strong bones and helping growth. 

‘Our review made it possible to assess whether increased milk consumption provides a survival advantage or not,’ he said. ‘We believe it does. 

‘When the numbers of deaths from coronary heart disease, stroke and colo-rectal cancer were taken into account, there is strong evidence of an overall reduction in the risk of dying. 

‘We found no evidence milk might increase the risk of developing conditions, with the exception of prostate cancer. ‘

The White Stuff: Milk doesn’t just build healthy bones

The reviewers say that encouraging greater milk consumption might eventually reduce NHS treatment costs because of lower levels of chronic disease.

‘There is an urgent need to understand the mechanisms involved and for focused studies to confirm the epidemiological evidence since this topic has major implications for the agri-food industry’ said Professor Givens. 

Study Finds Sunny Side of Eggs


From Live Science:

When it comes to public consumption of nutrition studies, an old adage applies: Everything in moderation.

The latest study looking at what you should eat involves eggs. Despite decades of advice that the cholesterol in eggs is bad for you, researchers in Canada now report evidence that eggs might reduce another heart disease risk factor — high blood pressure.

The scientists found egg proteins that, in laboratory simulations of the human digestive process, seem to act like a popular group of prescription medications in lowering blood pressure. The findings are detailed in the Feb. 11 issue of the American Chemical Society’s Journal of Agricultural and Food Chemistry.

From Science Daily:

ScienceDaily (Feb. 26, 2009) — A new study published in the March 2009 American Journal of Clinical Nutrition by Marek Naruszewicz and colleagues from Poland suggests that acrylamide from foods may increase the risk of heart disease. Acrylamide has been linked previously to nervous system disorders and possibly to cancer.

After ingesting large amounts of potato chips providing about 157 micrograms of acrylamide daily for four weeks, the participants had adverse changes in oxidized LDL, inflammatory markers and antioxidants that help the body eliminate acrylamide—all of which may increase the risk of heart disease.

Harvard Team Unlocks Clues to Genes that Control Longevity


From The Daily Galaxy:

Harvard Medical School Researchers have used a single compound to increase the lifespan of obese mice, and found that the drug reversed nearly all of the changes in gene expression patterns found in mice on high calorie diets–some of which are associated with diabetes, heart disease, and other significant diseases related to obesity.

The research, led by investigators at Harvard Medical School and the National Institute on Aging, is the first time that the small molecule resveratrol has been shown to offer survival benefits in a mammal.

“Mice are much closer evolutionarily to humans than any previous model organism treated by this molecule, which offers hope that similar impacts might be seen in humans without negative side-effects,” says co-senior author David Sinclair, HMS associate professor of pathology, and co-director of the Paul F. Glenn Labs for the Biological Mechanisms of Aging.

Scientists Discover 21st Century Black Plague That Spreads From Rats To Humans

Black Death: A brown rat, common in the UK, has been found carrying a new strain of bacteria called Bartonella rochalimae, which is deadly to humans

From The Daily Mail:

A new plague which jumps from rats to humans has been discovered by scientists.

Fears are growing that increasing numbers of brown rats – the most common kind in Europe – are carrying a strain of bacteria that can cause serious illness in humans from heart disease to infection of the spleen and nervous system.

The new strain of bacteria called Bartonella rochalimae is spread between rats by fleas, Taiwanese researchers have said.

It was first discovered in an American woman with an enlarged spleen who had recently travelled to Peru.

‘This event raised concern that it could be a newly emerged zoonotic pathogen,’ said Professor Chao-Chin Chang from the National Chung Hsing University in Taiwan.

New Longevity Drugs Poised to Tackle Diseases of Aging

From Wired News:

Cancer, diabetes, Alzheimer’s, Parkinson’s, heart disease: All have stubbornly resisted billions of dollars of research conducted by the world’s finest minds. But they all may finally be defied by a single new class of drugs, a virtual cure for the diseases of aging.

In labs across the country, researchers are developing several new drugs that target the cellular engines called mitochondria. The first, resveratrol, is already in clinical trials for diabetes. It could be on the market in four years and used off-label as an all-purpose longevity enhancer. Other drugs promise to be more potent and refined. They might even be cheap.
