If snuggling up on your side is the most comfortable, experts recommend lying on your left side. “Sleeping on your right pushes on blood vessels, preventing maximum circulation,” says Breus. Because of this added pressure on your veins, your body moves more frequently through the night to accommodate the lack of circulation, resulting in all that fitful sleep your Fitbit is tracking. The left side, however, allows for cardiovascular return, says Dr. Christopher Winter, medical director at Charlottesville Neurology and Sleep Medicine. “Meaning your heart can easily pump blood throughout your body when there’s less pressure on that region.”
