Dutch researchers found that levels of the stress hormone - cortisol, can be determined by analysis of hair. This way you can find out how much a person is under stress.
Experts believe that hair is a valuable source of information about human health. Identify the level of cortisol in the body is best for your hair and not on a routine blood test.
The scientists found that at high levels of the stress hormone in humans there is an increased risk of developing cardiovascular diseases. It turns out that exceeded the level of this hormone may also be a risk factor for heart disease.
The researchers managed to make a picture of the changes in cortisol levels during the three months the hair samples analyzed 283 elderly volunteers. The indicator of the stress hormone, as it turned out, was above average in people who are more likely to suffer from cardiovascular disease, stroke, diabetes, peripheral artery disease.
Hair, as the scientists reported significantly longer than the blood contain data about how over time there are changes in the level of cortisol, so the analysis of hair is probably the best method to accurately estimate the probability of developing the disease.
