Could your mind be causing your sickness?

If you're someone with goals, dreams, and a drive to be productive, your energy is your currency—but what happens when your body can’t keep up?

People just aren't feeling well. All aspects of ill-health are on the rise, whether it’s not having a good day today to significant sickness or chronic illness.

Sickness is on the rise and it's increasingly debilitating. We have far more chronic illness today than we did a couple of generations ago, even just one generation ago.

For professionals with demanding careers and personal responsibilities, illness is more than an inconvenience—it disrupts productivity, impacts performance, and affects quality of life.

What’s more concerning is that chronic stress and negative thought patterns may be quietly wearing down your body from the inside out.

The real question becomes:
Could your mindset be contributing to physical burnout or illness?

The science behind thoughts and physical symptoms

(Hint - Your body listens to your thoughts)

Every thought we have—especially those tied to stress, fear, or frustration—initiates a cascade of physiological responses.

Elevated heart rate, muscle tension, disrupted digestion, and hormonal imbalances are common side effects of psychological stress.

Even short-term stress responses can compound over time, particularly for people in high-pressure environments. Think of your body as a feedback loop: your mind sends a signal, your body responds accordingly.

Here’s a real-world example: fear vs. belief

During the Christchurch earthquakes, I worked with someone who turned visibly pale every time an aftershock occurred. What caused that reaction? Not the tremor itself—but her belief: “I’m going to die.”

It wasn’t reality triggering her stress response—it was the internal stress narrative. Her body reacted to the thought, not the event.

This is a clear example of how thought-driven health issues manifest physically.

Chronic negativity and its impact on professionals

Many professionals maintain an outward image of success while privately experiencing symptoms like:

  • Constant fatigue
  • Headaches or tension
  • Sleep disruption
  • Low immune resilience
  • Anxiety or irritability

These are not random.

They're often stress-induced health issues stemming from persistent negative thoughts, unresolved tension, or perfectionist self-talk.

If your internal dialogue sounds like:

  • “I can’t afford to slow down.”
  • “I’m not doing enough.”
  • “There’s too much to manage.”

…then your body is likely paying the price.

Why mindset matters more than we think

Consider this: if you believe your job is unfulfilling, your team is underperforming, or your efforts aren’t appreciated, those thoughts shape your emotional and physiological baseline.

Over time, this leads to:

  • Increased cortisol levels
  • Suppressed immune function
  • Decreased focus and cognitive sharpness

This is how we unknowingly think ourselves into fatigue, illness, or burnout.

Thought exercises to observe the mind-body link

Get present to your emotional patterns

Try this two-step reflection:

  1. Recall a moment when you felt intense fear or anger.
  2. Identify where you felt it in your body. Was it a racing heart, shallow breath, tight jaw, or tension in your neck?

Now, ask: What thought triggered that emotion?

Chances are, it wasn’t the situation itself—it was your interpretation of the situation.

99.99 times out of 100 the thing that we're fearing isn't actually happening or it's something that we're afraid is going to happen in the future. It's not happening in that moment of time. So it's easy to see in those moments that it's only the thought of what is going on that's causing the fear.

Now let's say, for example, our thought is that life is a terrible place. Life is horrible. My job is horrible, my relationship, everything that people believe their whole life is horrible. If they're consistently sending out that thought, even if they don't know it, imagine what's happening in the body. Stress is manifested mentally and then shows up in the body.

The lemon test: when your body reacts to imagination

Picture this:

  • You're holding a freshly cut lemon.
  • It's juicy, sour, dripping with citrus.
  • You raise it to your mouth and take a big bite.

Notice any reaction? Salivating? Face tensing? That’s your body reacting to imagination—not reality.

This illustrates just how powerful the mind is in generating physical responses.

How to interrupt the negative feedback loop

1. Identify recurring stress narratives

Start by getting honest about the mental scripts playing in the background.

Common ones for high performers include:

  • “I’m falling behind.”
  • “I don’t have time to relax.”
  • “Nothing I do is ever enough.”

These aren’t just thoughts—they’re cognitive stressors that influence your health outcomes. Awareness is the first step toward changing them.

2. Reframe with intention

Try this simple reframe process:

  1. Name the stressor: “I hate my job.”
  2. Find two truths that contradict it: “It pays the bills. It helped me build my network.”
  3. Shift focus: “What would I love to create instead?”

Even small shifts from resentment to gratitude or purpose can realign your energy and support a more resilient mind-body state.

Practical strategies for busy professionals

You may not be able to fly to Fiji every time life feels overwhelming—but you can build a mindset that supports vitality.

Here’s how:

  • Schedule joy: Block out time for things that energise you.
  • Declutter your mental load: Journal, reflect, or talk to a coach.
  • Reset your stress response: Breathwork, meditation, or movement.
  • Build positive associations: Focus on what you appreciate right now, not just what's missing.

If your internal stress response is always on, your body will eventually break down. But when your thoughts support your wellbeing, your body follows suit.

What healthy high performers do differently

People who sustain success and good health don’t ignore their thoughts—they train them.

They know that vitality doesn’t come from grinding harder, but from:

  • Loving their life—not just tolerating it
  • Investing in emotional well-being
  • Aligning performance with purpose

At 57, I still feel full of energy and clarity—not because I’ve avoided stress, but because I’ve learned how to shift my mindset and support my health from within.

You can, too.
