Working for a difficult boss can come with stress, long
hours and a poor office atmosphere.
But new research has found it can also be bad for your
health.
The stress of working for a bad boss over a long period of
time can cause serious harm to employees, the study found.
The researchers found that chronic stress causes changes in
the gene activity in immune cells.
These changes cause the cells to be primed to fight an
infection that doesn't exist.
This leads to inflammation in the body which is associated
with many health problems, including heart disease and diabetes.
Scientists at Ohio State University, in the U.S., made this
discovery while studying mice.
Their colleagues at other institutions also tested blood
samples from people living in poor areas and found that similarly primed immune
cells were present in these chronically stressed people.
‘The cells share many of the same characteristics in terms of
their response to stress,’ said Dr John Sheridan, associate director of Ohio
State University's Institute for Behavioural Medicine Research, and co-lead
author of the study.
‘There is a stress-induced alteration in the bone marrow in
both our mouse model and in chronically stressed humans that selects for a cell
that's going to be pro-inflammatory.
‘So what this suggests is that if you're working for a
really bad boss over a long period of time, that experience may play out at the
level of gene expression in your immune system.’
The findings suggest
drugs acting on the central nervous system to treat mood disorders might be
supplemented with medications targeting other parts of the body to protect
against chronic stress.
The mind-body connection is well established, and research
has confirmed stress is associated with health problems.
However, exactly how stress can harm health is still under
investigation.
Dr Sheridan has been studying mice for a decade to reveal
how chronic stress changes the brain and body in ways that affect behaviour and
health.
Working for a difficult boss causes chronic stress which can
lead to inflammation in the body - this is associated with long term health
problems such as diabetes and heart disease. Chronic stress can lead to inflammation in the body - this
is associated with long term health problems such as diabetes and heart disease
To study this he repeatedly subjects the mice to stress and
then tests their response.
He gives male mice living together time to establish a
hierarchy, and then an aggressive male is added to the group for two hours at a
time.
This elicits a ‘fight or flight’ response in the resident
mice as they are repeatedly defeated by the intruder.
‘These mice are chronically in that state, so our research
question is, “What happens when you stimulate the sympathetic nervous system
over and over and over, or continuously?” We see deleterious consequences to
that,’ Dr Sheridan said.
The research is published in the journal Proceedings of the
National Academy of Sciences.
