Researchers began analyzing health and sleep data in 2009 from 3,642 randomly selected participants ages 35 to 75 in Lausanne, Switzerland, who were recruited through the Swiss national health survey CoLaus. Scientists first asked about their previous weekly nap frequency and continued monitoring them for an average of five years per participant.
Most — 58 percent — did not nap regularly. About one in five people (19 percent) said they took one to two naps in a week, and about one in 10 (12 percent) took to three to five naps weekly, with about the same share (11 percent) taking near-daily naps.
Those who did not nap at all had a 48 percent higher likelihood of experiencing a stroke, heart attack or failure compared to those who napped once or twice a week. This result held up against age, nighttime sleep duration and daytime sleepiness, blood pressure and other cardiovascular disease risk factors and depression. Only those with severe sleep apnea or age 65 and up were excluded from the benefits.
However, those who napped between three and seven times a week had a 67 percent increased risk of heart-related risks, and also typically the worst health profiles — often older men, sleep apnea sufferers, smokers and overweight people. They also slept longer hours overnight, and still reported more daytime sleepiness. However, that risk was all but eliminated when those risk factors were removed. No link between nap duration and cardiovascular events was found.
