This rumor on gray hair was just proven to be true, a new study says

DespiteWhat your parents may have said, Sit too close to the television is probably not going to make you blind. Crack your joints is notwill cause arthritis. And drink coffee do not break your growth when you are a teenager. But with regard to health adagues, a new study showed that the old rumor about why your hair goes gray is especially true.

A new study showed that it was true that high stress levels can transform your gray hair.
If you are afraid to keep your color natural, you may want to find time to relax. A new study published on June 22 in the journalelife Hair samples collected from 14 volunteers from an average age of 35 and a split of seven men and women among the group. The study participants were then invited to create stress newspapers based on their schedules and weekly schedules.
The research team used a new method to capture very detailed images of tiny human hair slices to quantify theExtent of pigment loss, allowing them to see up to about twenty millimeter that represents an hour of hair growth. After comparing changes to each participant's log entries, the results showed that higher stress levels corresponded to hair pigment changes.

Hair that have already grown can not become gray suddenly because of stress.
While the results of the study are the first timeHair ranging gray and stress Have been quantitatively linked, you should not expect you to wake up with a brutal week at work on suddenly snowy white locks. "When the hairs are still under the skin in the form of follicles, they are subject to the influence of stress hormones and other things that happen in our mind and body", principal authorMartin Picard, PhD, Associate Professor of Behavioral Medicine in Psychiatry and Neurology of Columbia University, Viterelos College of Physicians University and surgeons, said in a statement. "Once the hairs grow scalp, they harden and crystallize these exposures permanently in a stable form."
Instead, researchers say that the changes made by stress were much more progressive. "If you use your eyes to look at the hair, it seems that it is the same color throughout the major transition. Under a high resolution scanner, you see small subtle color variations, and that's what we are measured, "explained Picard.

The results also found that stress gray was not a permanent change.
Fortunately, be put through your boss's mail does not necessarily mean that yourThe color of the hair disappears permanently. The researchers found that once the stress levels decreased, the hair follicles returned to produce more normal pigment levels in each strand - in some cases, almost immediately. "There was a person who went on vacation and five hairs on the head of this person returned to the dark during the holidays, synchronized over time," said Picard.
The authors of the study also emphasized limitations as to those who could see changes in their hair color. "We do not think that the reduction in stress in a 70-year-old child that has been gray for years darkened their hair or increasing stress in a 10-year-old child will suffice to rock their hair on the gray threshold", has explained Picard.
The conclusions could help shed light on the human aging process and help scientists "reverse".
Researchers finally concluded that their results showed that their external factors could play an important role in the changes that the body undergoes as we get older, which means that there could be major consequences for the understanding of the process. aging. "Just like rings in a tree trunk contain information about decades spent in the life of a tree, our hair contains information about our organic history," said Picard. "Understanding the mechanisms for" old "gray hair to return to their" young "pigmented states could give new clues to the malleability of human aging in general and the way it is influenced by stress".
Picard concluded: "Our data adds to a growing corpus of evidence that human aging is not a fixed biological process, but may, at least in part, be stopped or even reversed temporarily."
