Feeling Tired & Wired? How Cortisol Impacts Your Heart and Wellbeing

Are you constantly feeling tired but wired?

If you find yourself struggling to get a good night's sleep, waking up feeling unrested, or experiencing an unrelenting sense of stress—even when you're not especially busy—you aren't alone. Many people in the UK report similar symptoms, and elevated cortisol levels could be to blame.

What is cortisol and why does it matter?

Cortisol is often called the "stress hormone" because it's released in response to stress—as well as to manage your metabolism, blood pressure, and immune response. While cortisol is essential for health, when the body produces too much over long periods, it can impact your heart health, affect sleep, and even contribute to weight gain.

Common symptoms linked to high cortisol

• Persistent fatigue or trouble sleeping
• Unexplained weight gain, especially around the middle
• Worsening anxiety or mood swings
• High blood pressure
• Difficulty concentrating

Simple steps you can try today

While not all symptoms are due solely to cortisol, making lifestyle adjustments can help:

• Prioritise consistent sleep – aim for 7-8 hours a night
• Engage in regular physical activity, even just daily walks
• Explore relaxation techniques such as meditation, yoga, or deep breathing
• Maintain a balanced diet rich in whole grains and vegetables

Tip: Limit late-night caffeine and electronics before bed for better sleep quality.
