Could Squeezing Your Arms and Legs Help Prevent Strokes?

▼  A simple squeeze to your arms and legs might benefit your brain — turns out, the added pressure may improve the regulation of blood flow to your brain as well as levels of stroke-protective molecules, a new study suggests.
The study found that people who wore an inflated blood pressure cuff on one arm and leg for minutes at a time experienced more controlled blood flow to their brains. This method also increased molecules in the blood previously suggested to play a protective role in the brain, such as in preventing stroke, a group of researchers reported today (May 29) in the journal Neurology.
Previous research has suggested that "training" organs by restricting blood flow — and therefore oxygen — to them through periodically compressing the arms and legs may make them more resilient when problems arise.
For example, a trained heart may be more resistant to changes in blood flow during a heart attack. And such training may allow the brain to better regulate that organ's blood flow despite changes in blood pressure, a process called "cerebral autoregulation," the authors said.
"It is generally believed that impairment of cerebral autoregulation may increase the risk of brain injury, especially stroke," said study senior author Dr. Yi Yang, a neurologist at the First Hospital of Jilin University in China. "And there is currently no report on how to improve cerebral autoregulation in order to reduce the risk."
The researchers are optimistic that these simple compressions to the arms and legs may help reduce the risk of stroke, but much more research will be needed before any conclusions about stroke prevention can be drawn.
