A solid night's sleep may be as important as not smoking to prevent cardiovascular disease, a new study has found.
Researchers from the Netherlands found sleeping for seven hours or more a night may reduce the risk of cardiovascular disease (CVD) by at least 22%.
Getting enough exercise, eating well, not drinking too much and not smoking are all well-known to curb the risk of CVD, but the impact of sufficient sleep hasn't been studied at length, the study says.
"It is always important to confirm results, but the evidence is certainly growing that sleep should be added to our list of CVD risk factors," lead researcher Monique Verschuren, of the Dutch National Institute for Public Health and the Environment, said in a statement.
The study was published online Wednesday in the European Journal of Preventative Cardiology.
