People whose job is classed as 'high strain' have more than double the risk – a 122 percent increase – of developing mental illness in their middle age.

Mental illness the leading cause of time off work
Professor Harvey added: 'Mental illness is the leading cause of sickness absence and long-term work incapacity in Australia, equating to billion lost to Australian businesses each year.

'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.'
Past research shows stress linked to physical illness
Previous research has also shown that high levels of stress at work can increase the risk of heart attacks, and make people more likely to eat unhealthily and sleep and exercise less.
Stress can make people physically ill because it can stimulate white blood cells to react in the same way that illness does and cause the body to react as though it is fighting an infection when it is not.
