Saliva reveals stress levels, says Granada University
By thinkSPAIN Team Sat, Nov 10, 2012
By taking a sample of spit, the cortisone levels in the body are revealed during difficult or anxious times.
The higher the cortisone level, the more stressed the person is.
People who have trouble making decisions are usually the ones who cope less well with anxiety and turbulence in their lives, medics say.
The tests were carried out on a group of 40 women, all of whom were otherwise healthy.
They were exposed to a 'stressful' situation and their cortisone levels measured through their saliva.
Cortisone, the 'stress hormone', is secreted from the outer 'crust' of the kidneys.
It affects various bodily functions, including the musculo-skeletal system, the immune system and the metabolism.
Good decision-makers tend to produce less of this hormone, say investigators.
The results of the analysis have been published in the specialist magazine, Psychoneuroendocrinology.
