Count to 3
You may have just lowered your stroke risk.
In a study published in the journal Stroke, researchers noted that of 2,100 men, the anxious guys were three times more likely to have a fatal ischemic stroke than the more serene men. "Anxiety causes chronic overproduction of dopamine, a neurotransmitter that regulates the brain's control of circulation," says Ernest Friedman, M.D., a professor of psychiatry at Case Western Reserve University.
Counting to three—or reining in your racing mind in any other way—helps by stabilizing your levels of serotonin, the antidote to excess dopamine, says Dr. Friedman
