Stress and Your Body: The Biomarkers You Need to Check.

April is Stress Awareness Month, a time to recognise how stress impacts the body and daily life. In today’s fast paced world, stress is everywhere – long work hours, financial pressures, and the endless juggle of responsibilities. But while some stress is normal, too much can take a toll on your physical and mental health.

The Reality of Stress in the UK

  • 76% of adults say they have felt overwhelmed by stress in the past year. ¹
  • Work-related stress, depression, and anxiety accounted for nearly half of all work-related ill health cases in 2022/23, leading to 17.1 million lost working days. ²
  • Job pressure, financial worries, and lack of work-life balance are some of the biggest stress triggers. ³

If stress is part of your daily life, you’re not alone. But small changes can make a big difference.


What Is Cortisol, and Why Does It Matter?

You’ve probably heard of cortisol, often called the “stress hormone”.  It’s essential for survival – helping you stay alert, energised, and ready to tackle life’s challenges.  But when stress becomes chronic, cortisol levels stay high, which can lead to:

  • Fatigue and low energy
  • Weight gain
  • Trouble sleeping or feeling restless at night
  • Weakened immune system
  • Higher risk of anxiety or burnout

By understanding how stress affects your body, you can take proactive steps to manage it.


How Stress Impacts Your Body – Key Biomarkers to Watch

Stress doesn’t just affect how you feel – it leaves measurable signs in your body. By looking at certain biomarkers, you can get deeper insights into how stress is affecting your health.

C-Reactive Protein (CRP) – Inflammation Marker

CRP is a protein linked to inflammation in the body.  Chronic stress can increase inflammation, which raises your risk of:

• Heart disease and high blood pressure
• Joint pain and muscle fatigue
• Weakened immune system

Blood Sugar & Insulin Levels

Stress can cause spikes in blood sugar, leading to:

• Higher risk of insulin resistance and type 2 diabetes
• Energy crashes and mood swings

Cholesterol & Blood Pressure

Stress hormones can raise bad (LDL) cholesterol and blood pressure, increasing the risk of heart disease.


Tips to Reduce Stress and Regain Balance

  1. Identify Your Stress Triggers
    • Keep a stress journal to recognise patterns in your daily routine.
    • Recognise what causes tension- work, finances, lack of downtime – and make small changes.
  2. Set Boundaries at Work
    •Avoid checking emails after hours.
    • Take regular breaks to prevent burnout.
    • Speak up if you’re overwhelmed.
  3. Try Simple Stress-Busting Habits
    • Deep breathing: Try the 4-7-8 method.
    • Meditation: Helps improve focus and emotional resilience.
    • Exercise: Even a short walk can reset your mind and boost mood.
  4. Prioritise Sleep
    • Stick to a regular sleep schedule.
    • Limit caffeine and screen time before bed.
    • Create a relaxing bedtime routine (dim lights, read, stretch).
  5. Get a Health Check
    • Chronic stress affects more than just mood – it can impact heart health, digestion and immune function.
    • A cortisol test can reveal if stress is putting extra strain on your body.
