Napping regularly linked to higher risks for high blood pressure and stroke

Caveat: The study only includes a partial age demographic: "participants were between the ages of 40 and 69 and lived in the United Kingdom between 2006 and 2010".

Key point, as this is a co-relation and not a causation:

> “This may be because, although taking a nap itself is not harmful, many people who take naps may do so because of poor sleep at night. Poor sleep at night is associated with poorer health, and naps are not enough to make up for that”
