A recent study, your hair can also reveal information about your lifestyle, such as your emotional state, your stress level, and also the risk of a heart attack that you may eventually face. The study was conducted in 2008 and 2009.
Researcher Gideon Koren of the University of Western Ontario reveals that from the reading of a study by a colleague a decade ago that showed that cortisol produced by the adrenal gland is present in human hair, he decided to study the relationship Between levels of cortisol and levels of stress.
– As cortisol is a known stress biomarker and as hair grows about one centimeter in a month, I thought it could measure chronic stress over time – he says.
Koren tested his theory at the Meir Hospital in Kfar Saba, Israel, where he collected hair samples from 120 men. Research team members analyzed the 1.2 cm of hair close to the scalp, and using the cortisol level measurement, they did a “stress record” that covered the last three months. The experiment confirmed Koren’s theories: those who suffered a heart attack had significantly higher levels of cortisol in their hair.
The hair itself is made up of dead cells. The follicle, which is the region where its root is, however, is alive. The bloodstream that passes through the site carries substances such as cortisol that can leak into the follicles of the blood vessels of the scalp.
As the hair grows, the cortisol is carried to the wire. Taking into account the hair growth rate per month, you can determine the level of stress to which the individual has been subjected in recent months – reveals.
In fact, it turns out that the cortisol count in the hair is the most reliable measure of the hormone to be found by scientists to date. Previously, they had to resort to measures of cortisol in blood or urine, which store these data for only a few hours or days.
So, depending on the length of hair, a doctor can determine what is the behavior of the patient’s stress and how it oscillates over the months.
