In order to predict serious diseases, we need to learn how to recognize the signals our body sends – every change in the body means something, and this includes even a simple change in the hair.
If your hair contains high levels of the hormone cortisol, it may be a sign of an impending heart attack! A team of Canadian scientists has recently been examining how work, marital or financial problems affect the risk of cardiovascular diseases. They discovered that there is a biological marker which can predict a heart attack months before it occurs.
Cortisol is conventionally measured through blood, urine and saliva tests. However, the hair is different – it grows about a centimeter a month, so a strand long 6 inches can show a long period of increased stress levels. As professors Stan Van Mind and Gideon Koran from the University of Western Ontario found out, high levels of cortisol were present in the blood, urine and saliva of the subjects for days and hours before the analysis.
The study was based on analysis of hair samples from 56 subjects who had a heart attack and the results were compared to analysis of hair samples from men who haven’t had a heart attack, but were suffering from other diseases.
