Chronic Stress Triggers Gray Hair
Stress is proven to trigger a variety of diseases like heart disease, high blood pressure, cancer, until stroke. Besides being able to cause diseases, prolonged stress (chronic) are also able to make someone’s hair turn gray.
According to some researchers from Duke University, North Carolina, United States, hair color that changes is caused by the adrenaline hormone that arises during stress. The hormone can cause damage to the body, one of which makes the hair color change.
Researchers found this after injecting adrenaline for several weeks. They want to see the effects of prolonged stress experienced by a rat. Once injected adrenaline, anti-cancer protein called p53 decreases.
Whereas p53 is known as the ‘gene keeper’ that improves the deoxyribonucleic acid (DNA) damage. DNA, a molecule essential for all living cells, storing the genetic code that determines all human traits, like skin color, eyes, hair type, and so on.
Well, this DNA damage leads to decreased production of pigment to the hair. As a result, the hair color turns gray. “This research could also answer why chronic stress triggesr a decrease in the human condition, including gray hair,” said Robert Lefkowitz, researcher from Duke University, according to the DailyMail. The results of this study had completely been written in the Nature journal.
