Yes, walking fast increases heart rate. According to hcahoustonhealthcare.com, walking increases your heart rate, and walking briskly—about 3 to 4.5 mph—is considered a low-impact, moderate-intensity workout. This increase in heart rate improves blood flow and can help lower blood pressure.
In simpler terms, the faster you walk, the harder your heart has to work to pump blood throughout your body, leading to an elevated heart rate.
