Globe and Mail - Saliva may hold key to predicting burnout

Go ahead: Spit if you feel frustrated about your job. What your saliva reveals could alert doctors to whether you’re at risk of burnout at work, according to new Canadian research.

And testing saliva could also help people with symptoms of burnout avoid being put on medication that might actually make the condition worse, said Robert-Paul Juster, a doctoral student at McGill University in Montreal who helped design the research.

A clue that someone is suffering burnout is lowered levels of cortisol, often referred to as the “stress hormone” because it is secreted when we feel anxious or agitated. But if we are under continual stress, our bodies can shut down production of the hormone rather than try to keep up with the constant demand.
