2. Help the heart rest
From the moment you are born, your heart has had to continuously work non-stop to sustain life. How well the heart works is influenced by a variety of factors from diet to air quality.
When you lie on your left side, you are allowing gravity to help your heart pump blood. The aorta that carries blood from the heart to other parts of the body will tilt to the left at the beginning of this journey. In this position, the aorta will point down, helping the heart to work softer.
