Taking a daytime nap increases the risk of a stroke, according to new research. It can be an early warning sign of high blood pressure - which reduces oxygen to the brain, say scientists.
The findings add to evidence that nodding off in the chair has potentially serious implications. They are based on 360,000 Britons who were tracked for an average of around eleven years.
Corresponding author Professor E Wang, of Xiangya Hospital Central South University, said: "These results are especially interesting since millions of people might enjoy a regular, or even daily nap."
