LESS THAN SIX HOURS OF SLEEP

LINKED TO HARD­ENED AR­TER­IES

The Gulf Today - Panorama - - HAVE YOU HEARD? -

Sleep­ing less than six hours or wak­ing up sev­eral times in the night is associated with an in­creased risk of asymp­to­matic ath­er­o­scle­ro­sis, which silently hard­ens and nar­rows ar­ter­ies, warns a study.

“Fail­ure to get enough sleep and rest­less­ness dur­ing the night should be con­sid­ered risk fac­tors for block­ing or nar­row­ing of the ar­ter­ies,” said study au­thor Fernando Dominguez of the Span­ish Na­tional Cen­tre for Car­dio­vas­cu­lar Re­search (CNIC) in Madrid. The study, pre­sented at the Euro­pean So­ci­ety of Car­di­ol­ogy (ESC) Congress 2018 in Mu­nich, Ger­many, in­volved nearly 4,000 healthy mid­dle-aged adults who wore a waist­band ac­tiv­ity mon­i­tor for seven days to record sleep qual­ity and quan­tity. They were di­vided into ive groups ac­cord­ing to the pro­por­tion of frag­mented sleep, and four groups des­ig­nat­ing av­er­age hours slept a night — less than six (very short), six to seven (short), seven to eight (the ref­er­ence), and more than eight (long). The re­searchers found that those in the high­est quin­tile of frag­mented sleep were more likely to have mul­ti­ple sec­tions of ar­ter­ies with ath­er­o­scle­ro­sis com­pared to those in the low­est quin­tile.
