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.

Re­cent re­search ex­am­ined data on 116,000 peo­ple aged be­tween 35 and 70 from 21 dif­fer­ent coun­tries.

Af­ter an av­er­age fol­low-up pe­riod of nearly eight years, re­searchers recorded 4,381 deaths and 4,365 “ma­jor car­dio­vas­cu­lar events.” Com­pared to peo­ple who slept six to eight hours, those who slept a to­tal of eight to nine hours a day had a 5 per cent in­creased risk.

Those sleep­ing be­tween nine and 10 hours a day had an in­creased risk of 17 per cent — and those sleep­ing more than 10 hours a day car­ried a 41 per cent in­creased risk of car­dio­vas­cu­lar disease or death. The re­searchers also found a 9 per cent in­creased risk for peo­ple who slept a to­tal of six or fewer hours. Lead au­thor Chuang­shi

Wang, a PHD stu­dent at Mcmaster and Pek­ing Union Med­i­cal Col­lege, said: “Our study shows that the op­ti­mal du­ra­tion of es­ti­mated sleep is six to eight hours per day for adults.”
