Health is a state of complete physical, mental and social well-being, and not merely the absence of disease or infirmity.
World Health Organization, 1948
When we talk about mental health and mental well-being, we are referring to a person’s ability to realize their own potential, cope with the normal stresses of life, work productively and fruitfully, and contribute to their community.
Definitions of mental illness have changed over time. Broadly, mental illness refers to changes in patterns of thinking, feeling or acting that continue over time. It may interfere with daily functioning in social, work, and family contexts. Causes of mental illness may be biological, psychological, social, or any combination of these.
Mental health and physical health are deeply linked. Physical illness or injury can have a negative impact on mental health. Conversely, mental illness can be accompanied by a broad range of chronic physical conditions.
Signs of a possible mental health issue
There are a number of signs and symptoms that you may notice in yourself, a co-worker or a member that can indicate a possible mental health issue. Noticing signs is a key first step in determining your approach to a situation.
Watch out for:
Changes in eating/sleeping habits
Withdrawal/isolation
Alcohol or drug use
Changes in personal appearance
Changes in energy/sociability/physical health/behaviour
Loss of focus/productivity
Frequent absences
Errors or accidents on the job
Talking about strange ideas
If you notice signs of possible mental health issues, avoid making a diagnosis. Only a doctor can do that. Many of the signs and symptoms of one mental illness could also be an indication of another, or of other circumstances that are affecting someone’s mental health. Avoid passing judgement or making assumptions about someone’s behaviour. This can unintentionally cause serious damage.
