Today in unsettling news : Results published in a recent issue of the American Journal of Epidemiology suggest a correlativity between daylight napping and increase mortality risk .
The study , direct by University of Cambridge epidemiologist Yue Leng , reckon at the affiliation between day napping and mortality in a view of over 16,000 British man and woman . Their findings suggest that daytime nappers are closely a third more likely to die before they plough 65 ( even after they accounted for thing like sex , social class , smoke condition , and more ) . Here ’s the abstract :
Among the 16,374 man and women who answered query on catnap habits between 1998 and 2000 , a total of 3,251 die during the 13 - year follow - up . Daytime napping was assort with an increased jeopardy of all - cause mortality rate ( for napping less than 1 minute per day on average , hazard proportion = 1.14 , 95 % confidence separation : 1.02 , 1.27 ; for napping 1 hour or longer per daylight on ordinary , luck proportion = 1.32 , 95 % confidence separation : 1.04 , 1.68 ) , independent of age , sex , social class , educational point , married status , employment status , dead body mickle index , forcible activity level , smoking status , alcohol intake , depression , ego - reported worldwide health , use of hypnotic drugs or other medicine , time spent in bed at night , and presence of preexisting wellness conditions . This association was more marked for death from respiratory diseases ( for napping less than 1 hour , luck ratio = 1.40 , 95 % confidence interval : 0.95 , 2.05 ; for nap 1 minute or more , hazard proportion = 2.56 , 95 % confidence separation : 1.34 , 4.86 ) and in person 65 years of age or young . Excessive day napping might be a utile mark of underlying wellness risk , peculiarly of respiratory trouble , peculiarly among those 65 old age of age or untried .
It birth cite that we ’re talking about correlation here , not causing , so say that“taking a nap will criticise years off your life”is a bit dishonest , to say the least . Still , if you find yourself systematically drowse off in the day , there ’s reason to believe it could be linked to an underlying health issue . Leng and the other author of the present study line that “ the exact mechanism of these association continue unknown , ” but previous investigations into the link between napping and increased deathrate have founddaytime sleepinessto be associated with poorsleep hygiene , which itself is link up toa whole slew of other problem cardiovascular , respiratory and metabolic in nature .
The full outcome of the present field of study can be accessed in their entirety , spare of charge , at theAmerican Journal of Epidemiology .
