What is stress?

 

Feeling stressed? You’re not alone. Stress is a natural response that everyone experiences when under pressure. It’s not always bad. It can even be healthy. But when the stress is too much, lasts for too long or affects your daily life, it can impact your mental health and wellbeing.

If for the last two weeks or so you’ve found it hard to relax, or felt overwhelmed, panicky or anxious, your mental health may be at risk. On this page, we talk about stress and mental health, as well as how to reduce stress through various stress management techniques.

Signs & Symptoms of Stress

You may have heard of ‘fight or flight: your body’s automatic response to perceived danger. It prepares you to either confront a threat or escape it quickly. That’s why we notice changes, like a fast heartbeat, when we’re stressed – it’s our body reacting as if it's in danger, even if it's not life-threatening.

Being aware of signs and symptoms can help you notice when stress is building. Identifying its effects can also help you take action early and protect your wellbeing.

Stress versus anxiety

Unsure if stress is the same as anxiety? Both can feel similar, but they’re different. Stress usually comes from a specific challenge, while anxiety can linger, often showing up as constant worry or fear.

Stress

Stress is the body’s natural response to a perceived threat or demand, whether real or imagined.

  • Stress is often triggered by external events or situations, like a demanding job, challenging school or uni assignments, financial worries, or relationship problems.

  • Stress is usually temporary and subsides once the stressor is removed.

  • A stressor could be working to a tight deadline, having a fight with a loved one, or experiencing a chronic illness.

  • Stress may make you feel more emotionally reactive to everyday situations.

Anxiety

Anxiety is a feeling of unease, worry or dread that can happen either as a result of stress or without any obvious trigger.

  • Anxiety can arise from certain events or situations – but it can also build from within or have no clear cause at all.

  • Anxiety can persist even after a stressor has passed, and it can become a chronic condition.

  • It can show up as persistent worry about everyday situations, panic attacks, or intense fears about social situations, places or objects.

  • Anxiety may lead to your feelings snowballing into immense fear about things that are unlikely to happen.

Stress management technique

When life feels overwhelming, there are simple things you can do to feel steadier. You don’t need to fix everything at once – just start with what’s in your control, take small steps, and give yourself moments to rest and reset.

Stress and mental health conditions

Stress and mental health can be closely linked. Too much stress, or prolonged stress, can cause poor mental health or a relapse of a previous mental health condition.

Anxiety and stress

Anxiety can impact your ability to manage stress in daily life. It also causes many of the same physical symptoms as stress.

Post-traumatic stress disorder (PTSD)

Post-traumatic stress disorder can happen after you experience a distressing event. Symptoms can include difficulty relaxing, upsetting dreams or flashbacks of the event, and avoidance of anything related to the event.

Depression and stress

If you’re experiencing depression, stress can lead to a worsening of symptoms. You might become more easily overwhelmed by stressful situations or events. And your ability to cope might be reduced.
