Stress increases risk of heart attacks and strokes by nearly 60 per cent
Scientists spent years giving almost 300 adults regular brain scans to expose the peril
THE risk of heart attacks and strokes soars by more than half if people are stressed out, major new research reveals.
They are almost 60 per cent more likely to fall victim compared to folk who chill out.
Scientists spent years giving almost 300 adults regular brain scans to expose the peril.
The pioneering study also monitored their arteries, which suffered when the amygdala — the part of the brain associated with anxious feelings — experienced increased activity.
The researchers suspect a chain reaction caused by the amygdala alerting the rest of the body.
