Job strain at age 45 predicted mental health problems five years later.

Toxic jobs that have high demands along with low levels of control increase the risk of mental illness, research finds.

The study’s authors estimate that reducing job strain could prevent 14% of new mental health cases from occurring.

Job strain includes two factors:

• High demand: can come from a high work pace, conflicting demands, difficult co-workers, high intensity etc..
• Low levels of control: having little control over how the work is done. An inability to make decisions relevant to the work.

The study analysed 6,870 people in the UK at ages 45 and 50.

They found that job strain at age 45 predicted mental health problems five years later.

Dr Samuel Harvey, the study’s lead author, said:

“The results indicate that if we were able to eliminate job strain situations in the workplace, up to 14 percent of cases of common mental illness could be avoided.

Workplaces can adopt a range of measures to reduce job strain, and finding ways to increase workers’ perceived control of their work is often a good practical first step.

This can be achieved through initiatives that involve workers in as many decisions as possible.”

People need discretion in how they do their jobs along with control over the pace of work and how to deal with conflicting demands — or it can make them ill.

Dr Harvey said:

“These findings serve as a wake-up call for the role workplace initiatives should play in our efforts to curb the rising costs of mental disorders.

It’s important to remember that for most people, being in work is a good thing for their mental health.

But this research provides strong evidence that organisations can improve employee wellbeing by modifying their workplaces to make them more mentally healthy.”

The study was published in the journal The Lancet Psychiatry (Harvey et al., 2018).

Around 3% of people are thought to hear voices when there is no one talking.

People who drink a lot of caffeine — over 7 instant cups of coffee a day — have triple the risk of hallucinating, research finds.

Hallucinations can include hearing voices when no one is talking and seeing things that are not there.

Those who had high caffeine intake were three times more likely to report these experiences, along with sensing the presence of dead people.

The reason could be that caffeine boosts the production of the ‘stress hormone’ cortisol.

Too much cortisol may cause people to hallucinate.

Dr Simon Jones, the study’s first author, said:

“This is a first step towards looking at the wider factors associated with hallucinations.

Previous research has highlighted a number of important factors, such as childhood trauma, which may lead to clinically relevant hallucinations.”

The study asked 200 people about any hallucinatory experiences and their caffeine intake from products like energy drinks, chocolate bars, tea and coffee.

Dr Charles Fernyhough, who co-authored the study, said:

“Our study shows an association between caffeine intake and hallucination-proneness in students.

However, one interpretation may be that those students who were more prone to hallucinations used caffeine to help cope with their experiences.”

Dr Jones said:

“Hallucinations are not necessarily a sign of mental illness.

Most people will have had brief experiences of hearing voices when there is no one there, and around three per cent of people regularly hear such voices.

Many of these people cope well with this and live normal lives.

There are, however, a number of organisations, such as the Hearing Voices Network, who can offer support and advice to those distressed by these experiences.”

The study was published in the journal Personality and Individual Differences (Jones & Fernyhough, 2008).
