Mental health is how we think, feel (emotionally) and behave. Anxiety and depression are the most common mental health problems and can be brought about or made worse by work.
Stress is the harmful reaction people have to excessive pressure and, if intense and prolonged, it can lead to both mental and physical ill health. In some individuals that have an existing mental health problem, it can be more difficult to manage and control work-related stress, leading to the worsening of symptoms. In others, it may cause a mental health problem to arise.
There is often some confusion about the differences between pressure and stress. Pressure can motivate us to perform at our best, but when we experience too much of it we might feel unable to cope and this results in stress, which can then cause ill health.
