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.

On this page, we talk about stress and mental health and explore how to reduce stress now and over the long term. 

Signs of stress

You may have heard of “fight or flight” – your body’s automatic response to perceived danger. It’s the reason why we feel physical things like a fast heartbeat when we’re stressed.

If you know what stress feels like, you can take action early and protect your wellbeing. Here are some common signs and symptoms of stress:

Emotional signs

  • Reduced empathy
  • Burnout
  • Isolated or lonely
  • Dependence on alcohol or other substances

Mental signs

  • Being irritable or not present when with family or friends
  • Changes in eating or sleeping patterns

Stress versus anxiety

Stress and anxiety can feel similar, but they are different things. Stress usually comes from a specific challenge or pressure, 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 university assignments, financial worries, or relationship problems.
  • Stress is usually temporary and subsides once the stressor is removed.
  • Stress is the body’s natural response to a perceived threat or demand, whether real or imagined.
  • 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 the situation causing stress 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 and mental health conditions

Too much stress, or prolonged stress, can cause poor mental health or a relapse of a previous mental health condition. If you’re experiencing anxiety, depression, PTSD or another mental health issue, stress can lead to a worsening of symptoms and your ability to cope might be reduced.
