If you’ve just had a screaming match with someone – be careful for the next 2 hours. Because your heart attack risk will be over 8 times higher than normal. That’s due to the stress hormones flooding your body – and the rise in blood pressure and heart rate. So the next time you get riled up by a fight – or you get angry at traffic – ask yourself if it’s worth a medical emergency. Then, take slow, deep breaths. That’ll help relax your blood vessels and slow your heart rate, so you can get out of the anger-induced danger zone.
