30-Minute Exercise Can Help Prevent Lethal Brain Condition

Spending at least 30 minutes for exercise each week could significantly cut the risk of having the most lethal disorder of the cerebral circulation. Subarachnoid hemorrhage (SAH) is a type of stroke that occurs due to bleeding into the space surrounding the brain. 

The risk of death is high for people diagnosed with SAH. Estimates show that half of all patients commonly die within three months after the condition occur. 

To date, a number of studies are being conducted across the world to fully understand SAH and its risks. Some research suggested that smoking and high blood pressure could potentially increase the risk of having the deadly brain condition. 

A new study, published in the journal Scientific Reports, offers a potentially effective way to avoid SAH. Through analysis of data from nearly 70,000 people in Finland, researchers found that working out 30 minutes per week could reduce the risk by nearly 5 percent. 

Longer exercise increases the chances of avoiding the condition, the researchers said. Simple activities, such as walking or cycling, could significantly help. 

"Even moderate physical exercise, such as a 30-minute walk or bike ride four days a week reduces the risk of SAH by roughly 20 percent, regardless of age and gender," Joni Lindbohm, principal author of the research article, said in a statement. "As such, the finding did not really come as a surprise, as exercise is known to work well in preventing many other cardiovascular diseases."

Exercise also cut the risk for smokers and other people with high blood pressure. These people have the highest risk of having SAH. 

The brain disorder commonly occurs due to ruptured cerebral aneurysms, which cause blood to flow from the largest cerebral arteries into the space between the membranes surrounding the brain. Aneurysms lead to higher intracranial pressure and lower cerebral circulation.

"Even with no accurate scientific evidence of the biological mechanism of action produced by exercise in terms of SAH, the reduced risk is most likely connected with a reduction in a systemic inflammatory state, which also affects the walls of cerebral arteries," researcher Miikka Korja said. 

The research team suggested quitting smoking, balancing blood pressure and exercising regularly to fully minimize the risk of SAH.
