October is Mental Health Month in Australia, and I’d like to talk about it. In fact, I feel we need to talk about it more than ever.

Mental health and mental ill-health are complex, multifactorial, and more than anything, individualised and person-specific. While many people may experience the same mental illness, their personal causes and psychosocial reasonings may never be the same, and may never be experienced in the same way.

How one person experiences depression for example, and their subsequent choice of treatment, could be completely different to the next person. And as we know, it is not uncommon for treatment of mental health conditions to be started with pharmacological and/or psychological interventions, without a broader review that considers lifestyle factors.

I’d like to raise the question: do we feel, relative to modern day treatment opportunities, that pharmacological treatment and psychotherapy are enough for those with mental health conditions as a whole?

And more broadly speaking, are the current management strategies of mental health conditions consistently 1) preventing more conditions from occurring, 2) preventing someone’s systemic health from becoming any worse, or 3) the most economically cost-effective for mental healthcare consumers, and for our healthcare system?

The World Health Organisation (WHO) defines mental health as “a state of mental well-being that enables people to cope with the stresses of life, realize their abilities, learn and work well, and contribute to their community” (World Health Organization, 2026).

Mental health spans across a continuum, from being mentally healthy or ‘fit’ to mentally ill. We can ebb and flow among the differing characteristics from varying categories on the daily. This continuum details varying biopsychosocial factors that influence mental wellness vs mental illness, but please note it is not an exhaustive list.

Chart of the mental health continuum, from Thriving to Healthy, Reacting, Struggling and Unwell, with typical signs for mood, thinking, sleep and energy, connection, daily life and coping at each stage. Thriving to Reacting: look after the basics. Struggling and Unwell: reach out to your GP or a mental health professional, or in a crisis call Lifeline 13 11 14 or 000.
Adapted from the Mental Health Continuum Model (Department of National Defence, 2025).

On the right end of the continuum, we see traits commonly seen in those experiencing mental illness. Australia’s National Mental Health Plan 2003-2008 defined mental illness as ‘a clinically diagnosable disorder that significantly interferes with an individual’s cognitive, emotional or social abilities’ (as cited in Senate Select Committee on Mental Health, 2006).

What I am pleased to advise is that research is progressively and repeatedly demonstrating that exercise is a viable and clinically meaningful strategy of managing or improving mental health, mental illness and severe mental illness (Firth et al., 2015; Singh et al., 2023). Could this in fact be the most ideal combination: physical therapy, pharmacology, psychology?

If you take medicine for your mental health, keep taking it as prescribed. Talk to your GP before you change anything.

Here’s what we know:

Regarding physical health of people living with mental illness (Australian Bureau of Statistics, 2015; Australian Institute of Health and Welfare, 2026):

  • People living with mental illness are more likely to experience poorer physical health than the general population
  • People living with mental illness, and in particular severe mental illness (SMI), are more likely to experience comorbidity of physical conditions, more likely to be hospitalised for potentially preventable reasons, and tend to die earlier than the general population
  • There are an estimated 1.7 million Australians aged 16 to 85 experiencing both a mental illness and a long-term physical health condition
  • Almost 80% of premature deaths of people with mental illness are due to potentially preventable physical health conditions
  • In 2014-15, among people aged 18 years and over with co-existing mental and behavioural and physical health conditions, almost three-quarters (72.8%) reported no or low levels of exercise
  • People with co-existing mental and behavioural and physical health conditions were more likely to be overweight or obese (65.2%), compared with people with one mental and behavioural condition only (46.8%).
