Understanding mental health

Mental health is an essential part of your wellbeing. Even though you can’t see it in the same way as physical wellness, your mental health is just as real and important.

Mental health is made up of how you feel, think, behave and what you believe about yourself. It can affect your thoughts, emotions, focus, relationships, sleep, work and even cause physical symptoms.

For this reason, mental health and physical health are interconnected, as one can easily affect the other.

Who is affected

Everyone has mental health – that includes you and every person who has ever lived! Mental health is part of being human and it is likely to fluctuate at different times in your life, or even throughout different parts of each day. Therefore, mental health is best thought of as being on a continuum. The figure below shows the spectrum of thoughts and behaviour generally associated with feeling mentally well, all the way through to feeling mentally unwell.

It is normal to move up and down this continuum depending on life stressors and circumstances. Whilst we’d like to be operating at our best all the time, this isn’t necessarily realistic. Being human means going through hard times and feeling unpleasant emotions.

Spending short times in the ‘reactive’ or ‘injured' parts is an indicator that we need to look after ourselves. If you notice you are becoming stuck there, unable to bounce back, or you are sliding down the continuum and unable to recover from the deeper red zones, it may be an indictor your mental health needs some attention.

Common mental disorders

Anxiety 

Anxiety disorders are one of the most common mental disorders in Australia, with 17% of the population, or one out of six people, experiencing symptoms of an anxiety disorder in the last 12-months.

We all get anxious from time to time. This is a normal response to stressful events and usually passes when the stressor, for example public speaking, is over.

If anxiety increases to the point of getting in the way of life’s activities or is prolonged or excessive, it may be impacting your life enough to be considered an anxiety disorder.

Signs and symptoms of anxiety

The neuroscience of anxiety


Neuroscience is helping to shed light on what’s happening in the brain when people experience anxiety disorders.

Parts of the brain that are affected include:

 

 

 

 

 

 

Neuroscience research is showing us that changes in these important regions occur when people experience stress and anxiety disorders. For example, neuronal dendrites (the ‘branches’ of brain cells) whither in the PFC (reducing our capacity for logical reasoning and emotional regulation) and strengthen in the amygdala (enhancing our fear response). Evidence also points to dysregulation of the HPA axis in anxiety and stress disorders, making you more prone to seeking threats in the environment and responding to these.

Depression

Depression is a disorder that affects how we think, feel and act in unhelpful ways. Around 8% of Australians are considered clinically depressed.

While we all feel sad, moody or low from time to time, some people experience these feelings intensely, for long periods of time (weeks, months or even years) and sometimes without any apparent reason. Depression is more than just a low mood – it's a serious condition that affects your physical and mental health. 

Findings from neuroscience

Physical activity is associated with less anxiety, depression and burnout.

Regular exercise is linked to better blood flow to the brain and production of new cells in the hippocampus, a part of the brain which has shown a tendency for shrinkage in people with depression

Sleep deprivation is associated with a higher risk of developing depression.

About PTSD

Post traumatic stress disorder (PTSD) is a range of symptoms and reactions that someone can have as a result of going through a traumatic event. Not everyone who experiences a trauma develops PTSD, about 5-10% of Australians will struggle with PTSD at some time in their life.

PTSD is considered one of the stress related disorders, and if someone thinks they may have it, it is important to be formally assessed by a mental health professional.

Signs and symptoms of PTSD

Please note that this list may not cover all signs and symptoms.

Exposure to actual or threatened death, serious injury, sexual violence

Could be any of:

  • You have directly experienced the traumatic event
  • You may have witnessed this occur to someone else
  • You may have learnt this occurred to a close friend member or close friend, where it was violent in nature
  • Repeated exposure or extreme exposure to aversive details of a traumatic event (exposure through media does not apply)
Re-experiencing symptoms

Could be any of:

  • Flashbacks - strong memories that can make you feel as if the traumatic event is happening again, and you are in it 
  • Unwanted and vivid memories - the memories are strong and clear, but you know you are not experiencing the disaster again 
  • Nightmares- these upsetting dreams may have themes that relate to the disaster in some way (e.g. perhaps not being able to escape) 
  • Experiencing intense or prolonged distress at a cue that resembles something about the traumatic event
Hyper-arousal symptoms

This is when your flight/ fight/ freeze response is turned on and your body is looking out for danger. You may feel:

  • On edge  
  • Unable to relax  
  • Having rouble sleeping 
  • Having ifficulty focusing and concentrating 
  • Easily irritated  
  • Easier to startle 
  • Engaging in risky or destructive behaviours
Negative changes to emotions and beliefs
  • Feelings of anxiety, depression, anger, horror, guilt or shame  
  • Unable to persistently experience pleasant/positive emotions  
  • Feeling distant or cut off from others 
  • Loss of interest in activities you would normally enjoy 
  • Blocking out uncomfortable feelings or thoughts  
  • You may start to think differently about yourself, others or the world around you, e.g., ‘world is a dangerous place’, ‘I can’t trust others’, ‘I can’t cope anymore’, ‘I am broken’.
  • Unable to remember an important aspect of the event
Avoidance
  • Not wanting to see people or go to places or events that remind you of the traumatic experience 
  • Not wanting to talk about what happened or avoidance of memories, thoughts, emotions or physical sensations associated with the event
Duration of symptoms
  • Experiencing the symptoms for more than a month
Impact
  • The symptoms are causing significant distress or impairing ability to engage in everyday tasks - working, socialising, day-to-day activities

Risk factors for mental disorders

There is still much we need to learn and discover about mental health. Much of our research at the Thompson Institute is about better understanding of how the brain changes when we feel mentally unwell – and what we can do help that.

Some people develop a mental illness completely out of the blue. For others, there are some factors that increase the risk of mental health disorders, such as: 

Reflection activity

Protective factors 

Early intervention is also very powerful. Taking action when you first notice that your mental health is slipping supports the road to recovery. It’s also never too late to ask for help! 

There are also a variety of lifestyle factors that can protect our mental health: 

  • Sleep
  • Routine
  • Exercise
  • Nutrition
  • Mindfulness
  • Social connection 
  • And, a sense of purpose/meaning

Take a look at the Wheel of Wellbeing pictured opposite and identify a few of the protective lifestyle factors that resonate most with you. See if you can integrate more of these activities into your daily life.

 

Practical Tips

Finding support

Supporting others 

Sometimes, you may get the feeling that someone you know is struggling with their mental health. Often, we don’t know how to ask if they’re okay and are scared of appearing nosey.

However, you won’t ‘make someone worse’ or seem rude if you ask from a place of genuine care and respect. It is in fact very helpful to look out for others and start a caring conversation if you think they may be having a hard time. Here’s how: 

  • Look Out – for changes in your friends, family, colleagues (behaviour, appearance, mood) 
  • Speak Up – and start a caring conversation. Ask direct, non-judgemental questions that show you care. Use specific examples of what you’re noticing, ‘I’ve noticed you’ve seemed a bit down lately. Are you okay?”  
  • Listen – Acknowledge what the person is sharing and validate how they’re feeling. Don’t try to fix the problem.
  • Encourage help seeking – Support the person in accessing help (see support options below) 
  • Check in – as regularly as you can. Call, message, cuppa, catch up. “Did you end up chatting to the GP?” 
Accessing support

There are many options for people to access help and further assistance for mental health. A good general starting point is often to speak with a GP, who can help to assemble a care plan and connect in with other services. Be honest about the troubles you’re having and express your need for further support.

You could also consider:  

  • Employee Assistance Program (EAP) (any information you share is confidential and will not be shared with your workplace)  
  • Psychologists/ counsellors 
  • Community groups  
  • Family and friends 
  • Complementary therapists 
  • Specialist services (psychiatrist, drug and alcohol treatment services)
