6. Gives Your Heart a Break
From the very moment of its existence, the heart must beat without pause in order to sustain life. That’s a big job, and it can be impacted by a host of factors from diet to environmental air quality. It’s no wonder that heart disease is the leading killer of adults worldwide. To minimize your risk, make your heart’s job easier by sleeping on your left side.
It sounds like such a little thing, but when you sleep on your left side, you let gravity help the heart move blood. Your aorta carries blood from the heart to the rest of your body, and it arches to the left as it begins its route. When you lay so that it is pointed down, the heart has less work to get that blood moving.
