Walking at a brisk pace might do more than just help you stay fit—it could protect your heart.

A recent study published in Heart found that faster walkers had a significantly lower risk of developing heart rhythm disorders such as atrial fibrillation, bradyarrhythmias, and ventricular arrhythmias.

Researchers analyzed data from the UK Biobank, where participants self-reported their walking pace. Those who walked briskly had a 43% lower risk of developing rhythm issues, while average-speed walkers had a 35% lower risk compared to slow walkers. Benefits were especially strong in people under 60, particularly women.

Even walking just 5–15 minutes a day at a moderate pace (3–4 mph) made a noticeable difference. According to Dr. Jill Pell, the study’s lead author, “Walking is free and easy—it’s better to prevent problems before they start.”

In contrast, energy drinks like Red Bull may increase the risk of cardiovascular problems, including stroke and heart attack. Studies show Red Bull thickens the blood and stresses the heart. Its high levels of caffeine, sugar, and additives like aspartame can be harmful—especially when mixed with alcohol.

Choosing a brisk walk over a sugary energy drink might be a simple yet powerful step toward a healthier heart.
