If you’re planning to watch the Malaysia Open this year, your heart may be working harder than you realise, even if you’re seated in the stands.

Research in sports cardiology describes a phenomenon called spectator stress. During intense matches, the body releases catecholamines, adrenaline-related chemicals that are also released during light physical activity such as jogging.

Although the body is still, the nervous system reacts to tension, close rallies, and last-minute points as if you are actively involved. This can cause a temporary rise in heart rate and blood pressure.

For most people, this response is normal and short-lived. It may feel like palpitations, a warm flush, or a sudden surge of energy, especially during high-stakes moments.

For individuals with known heart concerns, simple strategies such as taking short breaks, staying well hydrated, and allowing excitement to ebb and flow can help maintain comfort throughout the event.
