Lifestyle changes are necessary to combat the 

cardiovascular diseases.

This was stated by the experts at the World Heart 

Day organised at the Aga Khan University Hospital.

The experts maintained that even more alarming is 

the fact that over a third of all deaths in Pakistan

 are caused by CVD which has emerged as the leading

 non-communicable disease in the country.

Cardiovascular diseases are a group of disorders of

 the heart and blood vessels. Heart attacks and 

strokes are usually acute events and are mainly 

caused by a blockage that prevents blood from 

flowing to the heart or brain.

In Pakistan‚ prevalence of hypertension has been found to be nineteen per cent in population

 over fifteen years of age.

Perhaps even more worrisome is that up to 25 per cent of the children in Pakistan are either

 overweight or at risk of being overweight.

This year the global theme `Take the road to a healthy heart' focused on lifestyle changes in

 order to prevent and control cardiovascular disease with a special focus on women and children.

An orange a day can keep cancer away: researchers

An orange a day can keep cancer away: researchers

Despite its potential toxicity (if taken in excess)‚ orange juice has many

 potential positive effects when it comes to cancer.

Orange could prove to be crucial in the prevention of cancer.

In a forthcoming review article from Nutrition and Cancer: 

researchers reviewed available evidence that links orange

 juice with cancer chemoprevention.

Despite its potential toxicity (if taken in excess)‚ orange

 juice has many potential positive effects when it comes 

to cancer‚ particularly because it is high in anti-oxidants.

Evidence from previous studies has indicated that orange 

juice can reduce the risk of leukemia in children‚ as well 

as aid in chemoprevention against mammary‚ hepatic‚ 

and colon cancers.

Sitting straight 'bad for backs'

Sitting straight 'bad for backs'

Scottish and Canadian researchers used a new form of magnetic 

resonance imaging (MRI) to show that sitting straight places an 

unnecessary strain on the back.

Sitting up straight is not the best position for 

office workers‚ a study suggests.

Scottish and Canadian researchers used a new

 form of magnetic resonance imaging (MRI) to show

 that sitting straight places an unnecessary strain

 on the back‚ BBC health reported.

They told that the best position in which to sit at

 your desk is leaning back‚ at about 135 degrees. 

Experts said sitting was known to contribute to 

lower back pain. 

Stay positive for a healthy heart

Stay positive for a healthy heart

Having a positive attitude encourages heart disease patients to 

exercise more which in turn increases longevity‚ says a study.

Researchers found the 

most positive patients 

exercised more and had a
42 per cent less chance of

 dying for any reason during

 the follow-up period.
Deaths were less than 

10 per cent.
Among patients with less 

positive attitudes‚ 50 deaths

 occurred 

(16.5 per cent). Positive mood

 and exercise also cut the risk

 of heart-related hospitalisations‚

 reports Science Daily.
Coronary artery disease is 

caused by narrowed arteries 

that don't provide enough blood and oxygen to the heart.
"We should focus not only on increasing positive attitude in cardiac
rehabilitation‚ but also make sure that patients perform exercise on a regular basis‚ as exercise is 

associated with both increased levels of optimism and better health‚" said Susanne S. Pedersen‚ 

one of the study authors and professor of cardiac psychology‚ the Department of Medical and

 Clinical Psychology‚ Tilburg University‚ the Netherlands‚ and adjunct professor of cardiac 

psychology‚ the University of Southern Denmark and Odense University Hospital‚ Denmark.
The new research has been published in the American Heart Association
journal Circulation: Cardiovascular Quality and Outcomes.

Sleep loss can make you fat: Study

Sleep loss can make you fat: Study

Researchers have long pointed to a correlation between a 

steep rise in obesity in industrialized nations and a decline in 

sleep duration.

Scientists had found evidence

 that a lack of sleep causes 

changes in brain activity that 

lead to people feeling hungrier

 and craving more fattening

 foods.

Researchers have long pointed

 to a correlation between a

 steep rise in obesity in

 industrialized nations and a

 decline in sleep duration.

A causal link was suspected‚

 but science has not been able to explain the mechanism‚ until now.

A team from the University of California said they used MRI (magnetic resonance imaging)

 scans to spot changes in the brain activity of sleep-deprived test subjects.

Researchers said these findings provide an explanatory brain mechanism by which

 insufficient sleep may lead to the development/maintenance of obesity.

Fewer teeth linked to poor memory: New study

Fewer teeth linked to poor memory: New study

Looking at 273 people ages 55 and older‚ the researchers found

 a modest but significant relationship between a person's number

 of natural teeth.

According to a new study‚ people who have fewer

 natural teeth perform poorly on memory tests.

Looking at 273 people ages 55 and older‚ the

 researchers found a modest but significant 

relationship between a person's number of natural 

teeth and his or her performance on memory tests.

In other words‚ it wasn't simply that both teeth and

 memory abilities tend to disappear with age.
