How Does Hot Yoga Affect Your Heart?

Hot yoga provides a significant and unique challenge to the cardiovascular system, effectively providing a moderate-intensity aerobic workout even while you are performing seemingly static postures. The heat is the key factor that elevates the cardiovascular demand. When you practice in a room heated to 95-105°F, your body's core temperature begins to rise. To counteract this, your brain signals your heart to pump more blood to the skin. This process, called vasodilation, allows heat to be released from the blood through the skin's surface. This requires the heart to beat faster and pump more forcefully, increasing your heart rate and cardiac output to a level comparable to a brisk walk or a light jog. With a consistent and regular practice, this cardiovascular conditioning can lead to numerous health benefits. Studies have shown that hot yoga can help to lower resting heart rate, improve blood pressure regulation, and enhance overall circulatory function. It strengthens the heart muscle over time, just like other forms of cardio exercise. However, because of this increased demand, individuals with pre-existing heart conditions or high blood pressure must consult their doctor before beginning a hot yoga practice.
