Hair may signal pending heart attack
In the not too distant future, your family doctor may pluck a hair from your head to see if you’re in imminent danger of a heart attack.
That’s because your hair contains an accurate record of your body’s production of cortisol – a hormone that surges through your body when you’re under stress. And stress can be the trigger for a potentially deadly cardiac event.
Researchers at the University of Western Ontario say they have developed a test to measure cortisol levels in hair. What’s more, they have used the test to show that the stress hormone can be exceedingly high in the months preceding a heart attack.
