How vital is sleep for arterial health?

Doctors can help by recommending good sleep hygiene, authors say

A good night’s sleep might be as important as exercise and diet when it comes to reducing patients’ cardiovascular disease risk, according to a landmark Spanish study.

After accounting for other risk factors, sleeping fewer than six hours increased the risk of non-coronary atherosclerosis by 27% compared with slumbering for 7-8 hours, the study of nearly 4000 bank employees found.

Fragmented sleep also increased the risk of plaque-filled non-coronary arteries by more than 34%, according to the study led by the Spanish National Center for Cardiovascular Research in Madrid.

“Overall, our findings support the potential role of healthy sleeping in protecting against atherosclerosis,”
