Stress is a normal part of life, but when it becomes chronic, it can have serious consequences for your heart health. Many Australians juggle demanding jobs, family responsibilities, and financial pressures, which can contribute to ongoing stress. Understanding how stress affects your heart and what you can do about it is important for long-term cardiovascular wellbeing.
When you experience stress, your body releases hormones like adrenaline and cortisol, triggering the ‘fight or flight’ response. This causes your heart rate and blood pressure to increase temporarily. While this reaction is helpful in acute situations, repeated or prolonged activation can damage blood vessels, raise blood pressure persistently, and increase inflammation—all risk factors for heart disease.
Scientific studies have shown that chronic stress is linked to higher rates of coronary artery disease, arrhythmias, and even sudden cardiac events. Stress can also indirectly harm your heart by encouraging unhealthy behaviours such as smoking, poor diet, physical inactivity, and poor sleep. People under stress may skip medications or medical appointments, further increasing risk.
Certain types of stress—such as work-related pressure, social isolation, grief, or anxiety disorders—are particularly associated with adverse heart outcomes. Additionally, women may experience unique effects, including increased risk of stress cardiomyopathy (also known as “broken heart syndrome”), a temporary but serious weakening of the heart muscle triggered by emotional distress.
The good news is that stress management techniques can make a significant difference. Regular physical activity, mindfulness meditation, adequate sleep, social connection, and professional counselling can help reduce the impact of stress. Your cardiologist can also work with you to address any underlying heart risk factors worsened by stress, such as high blood pressure or arrhythmias.
