Stress: What it is and why it matters

Stress gets talked about a lot, but most people don’t actually understand what’s happening in their body when they say, “I’m stressed.”

Stress is the body’s response to pressure or demand. That pressure can come from outside of us, work, relationships, environment or from within, like illness or ongoing health concerns. This isn’t just an opinion, it’s well-established across medical and psychological research.

According to Lifeline Australia, stress is a normal human response. In the right amounts, it can actually be useful. It helps us stay alert, meet deadlines and respond to challenges.

But the part that often gets overlooked is stress isn’t the problem. It’s how long we stay in it that starts to cause damage.

Most people I speak to aren’t dealing with one major stressor: they’re dealing with layers of it. And that’s where things start to tip over.

STress in a modern world:

Technology has made life easier in many ways, but it’s also blurred the line between work and rest. Being reachable 24/7 keeps the nervous system switched on.

Overcommitting has become normal. Saying yes when we mean no, trying to meet everyone’s expectations and pushing ourselves to keep up. It all adds up and takes a toll. This isn’t just about time management; it’s about pressure and identity.

When everything feels urgent, nothing gets done properly, and the first thing to drop is usually self-care. That’s not laziness; that’s overwhelm and overload.

We’re surrounded by noise, information and input, news, social media, conversations, notifications. The World Health Organisation recognises that environmental and psychological stressors, including noise and overstimulation, can impact mental wellbeing.

THE IMPACTS OF STRESS:

Short bursts of stress are manageable. Ongoing stress is where we see the real impact.

The Mayo Clinic outlines that chronic stress can contribute to:

• Headaches and muscle tension

• Fatigue and sleep disruption

• Increased blood pressure

• Strain on the heart

  
  

Stress also affects hormones. When stress is prolonged, the body continues to release cortisol, adrenaline and other stress hormones, which can interfere with:

• Digestion

• Immune function

• Healing and recovery

• Increased heart rate

• Raised blood pressure

• Sped up breathing

...just to name a few negative impacts. 

There’s also strong evidence from the National Institute of Mental Health that chronic stress can weaken the immune system, making people more vulnerable to illness.

For reproductive health, research shows:

• In women, stress can disrupt menstrual cycles and ovulation

• In men, it can affect testosterone levels and sperm production

  
  

It’s physiology!

Stress isn’t just about what’s happening around you. It’s also about how long your system stays activated.

how to stress less:

You can’t eliminate stress completely and you don’t need to. The goal is to come out of it regularly.

That’s the difference between coping and burning out.

Here are a few approaches that go beyond the usual “just relax” advice:

1. Create “off-duty” windows (non-negotiable)

Not just time off, but true off time. No emails, no notifications, no problem-solving. Even 30–60 minutes where your brain isn’t “on call” helps regulate your nervous system.

2. Lower the baseline, not just the spikes

Most people wait until they feel overwhelmed to act. Instead, build small daily habits that reduce your overall stress load, like walking without your phone or having quiet time before bed.

3. Audit your commitments honestly

Not everything is urgent. Not everything is yours to carry. Start asking: What actually needs to be done by me? It isn’t about productivity, it’s about pressure.

4. Reduce input, not just output

If your brain feels crowded, look at what you’re consuming. News, social media, constant noise, it all adds up. Reducing input can be just as powerful as “doing” less.

5. Schedule something that has zero outcome

No productivity, no goal, no result. Just something you enjoy. This is often the first thing people cut and the thing they need most.

Stress is part of being human.

It’s not a weakness and it’s not something you’ve “failed” at managing.

But when it becomes constant, it stops being helpful and starts impacting your body, your health and your quality of life.

Recognising it early and taking action is key, it isn’t just optional. It’s necessary.
