Job stress has been known to trigger heart problems in people who already have cardiovascular disease. Obesity, high blood pressure, lack of exercise and smoking contribute to heart disease. Study indicates that job stress also plays an important role. Workers who had the highest jab-related stress levels were more than twice as likely to die of heart disease, according to the study published in the British Medical Journal. Work stress involves too much work as well as a lack of satisfaction and feeling undervalued and unappreciated. Many people work long hours but if the effort is rewarding the stress is minimized. Job pressure is damaging when being overworked is combined with little of no control, unfair supervision and few career opportunities. The British Heart Foundation said the results support earlier research showing that people in jobs with low control, such as manual workers, could be at greater risk of heart disease than other employees. 'It is advisable for people to try to minimize levels of stress at work and for employers to allow people to have more control at work and to be rewarded for their success,' the foundation said in a statement. Which of the following will NOT possibly lead to heart disease?
A.
High blood pressure.
B.
Oversleeping.
C.
Smoking and being overweight.
