Looking at the data, the researchers split jobs into four categories: passive, low stress, high stress and active jobs.

The study classified certain jobs as "high stress" based on how physically and psychologically demanding they were, plus how much control workers had over their jobs.

The study found that waiting tables includes working long hours and physically demanding tasks. There are also elements that are out of an employee's controll, like unhappy customers.

Being a waiter was ranked higher in  stress than being a doctor, according to the study.

The study concludes that because of the high level of stress, being a waiter can have a detrimental effect on the individual's health.

"Having a lot of job stress has been linked to heart disease, but studies on job stress and stroke have shown inconsistent results," said Dr. Dingli Xu of Southern Medical University. "It's possible that high-stress jobs lead to more unhealthy behaviors, such as poor eating habits, smoking and a lack of exercise."
