A daytime sleep could have cardiovascular benefits according to new research by Ryan Brindle and Sarah Conklin, PhD, from Allegheny College in Pennsylvania in the US.

Simply taking more steps every day not only helps ward off obesity but also reduces the risk of diabetes, finds a study published on the British Medical Journal website.
