June 5 (UPI) -- An afternoon snooze might seem appealing to middle-aged folks and seniors, but these naps could carry a high cost.
People with certain types of napping patterns have a greater risk of an early death, researchers are slated to report at an upcoming meeting of the American Academy of Sleep Medicine.
"People who slept longer during the day, had irregular daytime sleep patterns, or slept more around midday and early afternoon were at greater risk, even after accounting for health and lifestyle factors," lead researcher Chenlu Gao, a postdoctoral research fellow at Massachusetts General Hospital in Boston, said in a news release.
The findings call into question the whole concept of the "power nap."
