Too much sleep ‘bad for your heart’

Manchester Evening News - - NEWS -

GET­TING too much sleep may be bad for your heart, a new study has found.

Re­search, pub­lished in the Euro­pean Heart Jour­nal, con­cluded that the amount of time a per­son sleeps is linked to their risk of car­dio­vas­cu­lar dis­ease and pre­ma­ture death.

It found sleep­ing too much – more than six to eight hours a day – raises the risk of se­ri­ous health prob­lems and fa­tal­ity.

The study ex­am­ined data on 116,000 peo­ple aged be­tween 35 and 70 from 21 dif­fer­ent coun­tries. It an­a­lysed par­tic­i­pants and re­turned to them about eight years later.

Re­searchers recorded 4,381 deaths and 4,365 ‘ma­jor car­dio­vas­cu­lar events’.

They found peo­ple who slept longer than eight hours had a higher risk of dy­ing or de­vel­op­ing dis­eases of the heart or blood ves­sels in the brain com­pared to those who slept for be­tween six and eight hours. “Sleep is es­sen­tial to hu­man health, and peo­ple spend about a third of their hours sleep­ing. It is in­creas­ingly re­garded as an im­por­tant life­style be­hav­iour that can af­fect car­dio­vas­cu­lar dis­ease (CVD) and death,” the team of in­ter­na­tional re­searchers wrote. Com­pared to peo­ple who slept six to eight hours, those who slept a to­tal of eight to nine hours a day had a five per cent in­creased risk.
