Can Stress Harm Your Heart? The Cortisol Connection Explained

Does stress really impact your heart?

Are you dealing with daily pressures from work, family, or finances? Many adults in the UK struggle to unwind, often experiencing tension, racing heartbeats, or spikes in blood pressure. If this sounds familiar, you may wonder how stress is affecting your long-term heart health.

What's the science behind stress and heart disease?

When you feel stressed, your body releases cortisol. This hormone is vital in the short term (helping you respond to challenges), but when elevated for weeks or months, it can:

• Increase your heart rate and blood pressure
• Cause your blood vessels to narrow
• Raise blood sugar and cholesterol levels

Over time, these effects may contribute to heart disease, especially for those at risk due to age, genetics, or other conditions.

How can you protect your cardiovascular health?

• Exercise regularly – even brisk walking can lower cortisol
• Practice mindful activities like yoga or deep breathing
• Prioritise a balanced UK diet (Mediterranean-style is excellent)
• Make time for rest and social activities

"Managing chronic stress is a vital step in supporting both physical and emotional wellbeing."
