Despite the health benefits of napping, researchers have found a nap should not be too long, reports CBC.
For older adults, naps over 90 minutes are not good — it’s excessive napping, says Dr. Atul Khullar, medical director of the Northern Alberta Sleep Clinic. He says a short nap can be useful, but longer ones can be disruptive.
“Excessive naps of 90 minutes, or a couple of hours, almost is a biological emergency. The body is not supposed to be doing that.”
