Exercise may speed up stroke recovery, Edinburgh scientist says

Regular exercise can speed recovery for stroke survivors and may reduce their risk of having another stroke, according to an Edinburgh scientist.

Professor Gillian Mead's findings contrast with commonly held fears that exercise may trigger a further stroke.

She has looked at how exercise benefits stroke recovery for 10 years.

People who have been active before their stroke are more likely to make a recovery but less is known how exercise can affect recovery after a stroke.

The Edinburgh University expert will be speaking about her research at a public event this week as part of the Edinburgh International Science Festival.

Her findings reveal that a structured physical training plan - including aerobic, strength and balance training - can help stroke survivors to become more mobile, improve their balance and reducing their disability.

Exercise programmes

Professor Mead is currently investigating whether breaking up long periods of sitting or lying with short periods of movement might help to bring down the risk of having another stroke.

One in six people in Scotland will have a stroke in their lifetime and survivors can be left with varying degrees of disability.

More than half of all people who survive a stroke require support to live independently.

Professor Mead said: "We're working with fitness experts to determine the best exercise prescription for stroke survivors.

"It's also important that we understand more about the factors that put patients off from taking part in exercise programs, and how we can motivate them to take advantage of the benefits."

Avoid Flu by doing Vigorous Exercise

By doing a minimum of two and a half  hours of vigorous exercise a week can help you prevent from having a flu.

A total of 4800 participants took the survey online conducted by  the London School of Hygiene and Tropical Medicine.

A moderate exercise will  not help prevent the flu and flu rates have been down this year's winter.

There health status are monitored weekly and  are then required to log in each week and note how they are feeling, and whether or not they have any flu-like signs.

The study shows that 100 cases of flu per 1,000 people can be avoided just  by doing vigorous exercise. 


This data is also the lowest for the past five years the survey was conducted. During the winter season only 4.7 percent catch flu for this year compared to 6 percent last year and 5 percent of the children reported flu symptoms compared to a 7.9 percent last year.

According to Dr Alma Adler, of the London School of Hygiene and Tropical Medicine that results should be taken with cautions but results prove the benefits of exercising. A fine weather is a chance to exercise and increase your immunity during spring time.

Flu Survey helps government in their health programs, and can be access into Public Health England's national flu surveillance programmes and is released at the beginning of National Science & Engineering Week.

Smoking and Breast Cancer

Young women who smoke have a higher risk of common types of breast cancer based on the latest study.

This study showed that women between 20 and 44 who smoked a pack of cigarette per day for at least 10 years is 60 percent more likely than those who smoke less to have estrogen receptor-positive breast cancer.

According to Dr. Christopher Li that there is a increase proof that breast cancer is another cause of smoking.

Prior researched showed evidence between smoking and cancer. This older studies have a different results for younger women who smoke.

Many unanswered questions were raised if smoking increased the risk of some forms of breasts cancers but not others. 

According to Li, a  senior author from the Fred Hutchinson Cancer Research Center in Seattle that there are  sub types of breast cancer and they have examine how smoking affects its sub-type.This data came from Seattle who were diagnosed with breast cancer between 2004-2010.

Base on the data from National Cancer Institute, there is one in every eight women that can develop breast cancer but the risk is lower for younger ones.

Young women who smoked were 30 percent to more likely develop breast cancer compared to those who never smoked.

The findings showed that women who smoked for at least 15 years were 50 percent more likely to have estrogen receptor positive breast cancer than smoker for a few years.

Excessive Sugar in your diet can lead to heart disease

Eating foods loaded with lots sugar can help increase the risk of premature death from heart disease that is why citizens are urging Canadian and U.S. governments to offer dietary limits on sugar.

For an individual taking 2000 calories a day that is equivalent to drinking a bottle of soft drink in vending machines would reach the new level of the latest U.S. study that suggests the risk of death from cardiovascular disease (CVD).

According to the U.S. Centers of Disease Control and Prevention in Atlanta "A higher percentage of calories from added sugar is associated with significantly increased risk of CVD mortality,"

This finding was based on the national health and diet surveys between 1988 and 2010 of more than 30,000 Americans with an average age of 44. The results suggest that a fatal heart risk is increased once added sugar intake goes beyond 15 per cent of total calories.

"Too much sugar does not just make us fat; it can also make us sick," said Laura Schmidt, a health policy specialist at the University of California, San Francisco.

The American Heart Association suggest not more than 25 grams a day or six teaspoons of sugar for women (five per cent of a 2,000-calorie a day diet) and 38 grams or nine teaspoons a day for men (7.5 per cent of daily calories).

In 2005, a team of experts at the Institute of Medicine, suggest that the Canadian and U.S. governments, should limit sugar consumption to less than 25 per cent of total calories. The World Health Organization (WHO) suggests less than 10 per cent of the total daily consumption.

According to the study there were 831 people who have died from heart ailment in the span of the 15 year study. The study also included other factors that causes heart disease such as smoking, inactivity and excess weight into account.
