. A half-hour daily walk was associated with reduced probability of premature death from stroke and less dangerous consequences of such hemorrhages, according to a paper published in the journal Neurology.

«We find more and more evidence that physical activity protects the brain from disease and damage, and our work is no exception in this regard. We need a more long-term observations and experiments to understand why the level of physical activity affects the severity of the consequences of stroke,» notes Catherine Sunnerhagen (Katharina Sunnerhagen) from the University of Gothenburg’s (Sweden).

Cells of the human body and other living things need a constant influx of nutrients and oxygen for normal life. Many of them can live a long time without oxygen, a few tens of minutes or even hours, but eventually the lack of it will lead to the destruction of mitochondria, the cellular «power plants» and other violations in the cells, causing their mass death.

The most vulnerable cells of the brain – the onset of oxygen starvation after a few minutes, causing very serious consequences, which usually cannot be reversed. Such changes can occur both during the «big» stroke, and less serious problems with the working of the blood vessels of the brain.

Sunnerhagen, and her colleagues have found a simple way to protect yourself from the dangerous effects of stroke, by studying the data that was collected by the University hospital during the treatment of patients affected by the stroke.

In total, during recent years there were approximately 2300 patients who recently had a stroke and undergoing rehabilitation therapy. The doctors, in addition to restoring the functioning of the brain and limbs of their patients, systematically studied their diet, lifestyle and other factors potentially associated with development of problems in the blood vessels of the brain.

As it turned out, a major risk factor in the development of the most severe forms of stroke and all similar attacks in General was the lack of physical activity and a sedentary lifestyle. On average they are 1.2 times more likely to suffer from hemorrhages in the brain than their peers who regularly engaged in exercise.

According to doctors, the most unpleasant consequences of strokes could be avoided, spending approximately four hours per week, or about half hour a day, exercise, and light exercise.

As pointed out, Sunnerhagen while their findings do not say that walking and charging was the main or even the only reasons why active people are less likely to suffer from severe forms of stroke. In the near future, scientists plan to check whether it is actually observing a wider group of people.
