- Each participant gave a daily urine sample when they first arrived at work and then four times throughout the day. 

- Self-reports of mood, alertness and nicotine + caffiene consumption were given.

Baseline measurements were also taken at home of:

- Aldrenaline levels in urine.

- Body temperature

- Self-rating of words such as sleepiness, efficiency etc from a scale of 0 to maximal.

- Caffiene and nicotine consumption.

5 of 7


1) In the first urine samples of the day, the high-risk group had aldrenaline levels twice as high as their baseline and this continued to increase throughout the day.

2) The control group had aldrenaline levels 1.5 times higher then the baseline and this decreased.

3) The high-risk group also reported feeling more irritated and rushed, having a low well-being.

The repetitive work which required attention to detail and was high paced and mechanised caused the most stress in the high risk group.

Even those with less stressful jobs were more stressed at work than home - so all jobs cause some stress.
