This study was conducted by Tom Jackson, Gillian Ragsdell, and Laura Marulande-Carter from Loughborough University. They observed the effect of emails on workers in a government institution of English.
They measured the blood pressure, heartbeat, cortisol level, and dairy of 30 workers in responsibility of reading and replaying emails.
And, the result was 83 percent of the workers got stressed when sending and replying correspondence emails. Their blood pressure, heartbeat, and cortisol level increased as a result of adrenal gland secretion in time of responding emails.
However, it depended on the kinds of emails to reply. The workers showed positive attitude toward the on-time information. This helped reduce their workload and made them pleased to reply. In time of having emails with irrelevant information, they needed to put more attention. Their negative response led to their condition of anger.
Then, why could emails cause the participants to be stressed? The reasons were misinterpretation, expectation, and alienation.
Perhaps, it was due to the language of emails. According to a study of a software company, contractually, negative emails send a response faster than positive ones. In addition, the unpleased persons tend to response emails within 24 hours when compared to their pleased colleague.
“Our brain can only deal with eight up to twelve duties in one time. And, if you cannot complete those duties, you will be overloaded and get tired,” said Jackson, a chief of the project.
An email is only one of the stressing events a worker experiences during the workday. Though stress is a natural response of our body to protect against the threats such as predators and aggressors, too much stress may lead into a serious healthy risk.
Overexposure to the stress-causing hormone may lead into heart attack, sleeping and digestive problems, depression, obesity, memory disorder, and skin sickness like eczema.
During the stressing condition, cortisol controls many functions in our body such as bodily immunity, digestion, and reproduction system. Cocktail hormones spread throughout our body during the stress, affecting an area in our brain from which our mood, motivation, and fear are controlled. Thus, one’s mood easily changes when s/he is getting stressed.
American Psychological Association (APA) explains some of the reasons the workers are getting stressed in their workplace. The recent decline in economy has caused uncertainty of work, becoming a concern from millions of people. Stress due to workload comes from the hopelessness, dissatisfaction, in job description, unrelated job with their competence, and job management.
