First established in 2000 by the World Heart Federation, World Heart Day is the world’s largest cardiovascular awareness campaign. Held annually on 29th September. What began as a day of awareness has grown into a global movement, encouraging millions to take charge of their heart health through education, lifestyle change, and community action.
In 2025, the campaign theme
— “Love Your Heart, Live Your Life” —
reminds us that heart health is not just a medical concern; it’s a personal, social, and public health priority.

How does heart rhythm factor into overall heart health, and why is it significant on World Heart Day?
Heart rhythm—the electrical activity that keeps your heart beating steadily—is fundamental to cardiovascular health. Irregular heart rhythms, or arrhythmias, can increase the risk of complications like stroke or heart failure. World Heart Day is a perfect reminder to pay attention not just to heart attacks and cholesterol, but also to heart rhythm health. Simple lifestyle measures and early detection through screening can help manage arrhythmias effectively and protect your heart’s natural beat.
What simple lifestyle changes can people make to improve their heart health?
There are five foundational habits that anyone can adopt for a healthier heart:
1. Manage stress and prioritise sleep: Chronic stress and poor sleep elevate inflammation and can disrupt your heart rhythm. Daily mindfulness, restful sleep, and unplugging from screens help your heart recharge.
2. Eat for vitality: Follow a Mediterranean-style diet rich in vegetables, legumes, whole grains, fish, nuts, olive oil, and fruits, while limiting processed foods, sugary drinks, and salt.
3. Move your body: Aim for at least 150 minutes of moderate exercise each week—whether that’s brisk walking, swimming, cycling, or even dancing. Movement boosts circulation and lowers blood pressure.
4. Quit smoking and avoid second-hand smoke: Smoking doubles your heart attack risk, but the good news is benefits start within hours of quitting and last for decades.
5. Monitor your vital numbers: Keep track of your blood pressure, cholesterol, blood sugar, and waist size—these silent markers predict your future cardiovascular risk.
I’ve heard our body clock affects heart health. Can you explain?
Absolutely. Our circadian rhythm—our internal 24-hour body clock—plays a crucial role in cardiovascular function. Disruptions like poor sleep, late-night eating, and irregular daily routines can increase the risk of high blood pressure, metabolic problems, and heart rhythm issues. Prioritising consistent sleep schedules, getting morning sunlight, and eating earlier in the day helps synchronise your heart with its natural rhythm.
What final message would you like to share for World Heart Day 2025?
The heart beats around 100,000 times a day—often unnoticed, but never unimportant. This 29th September, let’s pause and listen. Heart disease is not just a disease of ageing. It affects people of all ages, including women, young adults, and children. And while advanced treatments have improved survival, prevention remains the most powerful tool.

Remember, a healthy rhythm is the key to a healthy life. Let’s take it to heart!
