A study of nearly 1,300 women in Mexico and Iceland found that the top quintile who experienced stress had nearly a quarter of the concentration of cortisol in their hair compared to those in the bottom quintile.

How are you tense? Scientists may soon be able to find out by looking at your hair

  • The study suggests that the concentration of cortisol in the hair can indicate how stressed you are
  • Researchers studied hair levels in nearly 1,300 women in Mexico and Iceland
  • The top five stressed women had nearly a quarter of their cortisol concentration

Feeling stressed can tear your hair.

But scientists may now be able to find out how much stress you’re really under by examining the locks themselves.

Researchers have found that they can accurately detect the levels of cortisol – the body’s main stress hormone – in your hair.

So far, scientists have only been able to detect the stress hormone in blood, urine or saliva.

The team said the findings suggest that measuring the hormone in the hair could be a good way to identify chronic stress.

This condition can, over time, cause anxiety, insomnia, high blood pressure, and even a weakened immune system.

A study of nearly 1,300 women in Mexico and Iceland found that the top quintile who experienced stress had nearly a quarter of the concentration of cortisol in their hair compared to those in the bottom quintile.

What is the stress hormone cortisol?

Cortisol is a built-in alarm system in nature.

Although stress is not the only reason for its production, it has been called the “stress hormone” because it is released when the body is in a “fight or flight” mode.

It is produced in the kidneys which is excreted into the bloodstream.

Normally, the body produces higher levels in the morning and lower at night.

But if levels remain too high for too long, it can cause a host of health problems, including anxiety, depression, heart disease, and difficulty sleeping.

It can also cause a condition called Cushing’s syndrome that causes rapid weight gain, bruising easily, muscle weakness and diabetes.

The study, published in PLOS Global Public Health, analyzed hair samples from 881 women in Mexico and 398 women in Iceland.

The researchers took the hair from the roots and analyzed the 3cm section closest to the scalp in a machine.

Hair grows 1 cm per month, so the area represented the last 3 months.

Then the same women were given a 10-item questionnaire asking them how stressed they were.

The questions asked them to what extent they “found their lives unpredictable, uncontrollable and overloaded”.

They answered on a five-point scale and the researchers divided the respondents into five groups based on their total score, indicating how stressed they were.

The results showed that women who scored in the top quintile for stress levels had 24.3 percent higher cortisol levels than those in the bottom quintile.

Study author Dr Rebecca Lynch, from Reykjavik University, said the study suggests that measuring cortisol in hair could hold promise in diagnosing chronic stress.

The researchers wrote: ‘An association between perceived stress and [hair cortisol concentration] It is found in a sample of women from diverse geographic and cultural backgrounds.

“[It supports] hypothesis that [hair cortisol concentration] It is a viable biomarker in studies of chronic psychological stress.
