There is new evidence that daytime naps may be associated with a lower risk of heart attack or stroke, but only if limited to several times per week.
The study, published on Monday in Heart magazine, is: based on data collected from nearly 3,500 people living in Switzerland.
"We looked at healthy adults and found that people who get accidental attacks – once or twice a week – have a lower risk of heart disease than people who haven't slept at all," said Nadine Hausler.
Hausler and her colleagues tracked the participants for five years, all between 35 and 75, basically healthy without any heart disease data, and no one was overweight. sleep deprived
Often More than half (58 percent) said they had never taken a daily siesta, while about one in every 10 said that they nodded almost daily.
About one in five people hit what hit. researchers found the sweet spot: one to two times a week.
It is this frequency of naps that is associated with a 48% reduced risk of heart attack, stroke, or heart failure.
The length of the diaper did not seem to affect the findings and included something quick, a five-minute diversion to an hour delay plus As the study was observational, it could not prove cause and effect.
"Maybe those people who sleep once to twice a week are the ones who make naps a priority because they know they don't sleep enough during the week," said Celine Wind, an assistant professor at the University of Colorado Boulder, who studies circadian rhythms and sleep disturbance.
How naps can affect heart health is unclear.
"The best guess is that daytime naps just relieve the stress of getting enough sleep," Hausler said.
A large study of healthy adults living in Greece, published in 2007, found that those who dozed at least three times a week had a lower risk of fatal heart attacks. The greatest benefits are found in working men and researchers theorize at a time when naps help reduce stress.
This does not mean that doctors need to start writing prescriptions to take a nap for optimal heart health, mainly because there is no way of knowing what "dosage" is best.
"What is the time, duration?" and the frequency of seizures? Are we taking a 5 minute nap for a nap? "writes Yue Lang, an epidemiologist studying sleep behavior at the University of California, San Francisco, in an editorial published with the new study.
" We don't really know much about naps, "Lang told NBC News." We have a lot to learn "
Hausler agreed." It is really important that other studies confirm these findings, "she said.
Much more is known about the benefits of having a good sleep.
" Every physiological function we look at – from metabolism to the immune system – it's all built into how much you sleep, "said Wind.
Lish Sleeping also increases the risk of obesity, a known risk factor for heart disease.
But when it comes to daytime sleepiness, there seems to be a fine between 19659002] A study published in February found that people who miss out on missed Sleep on weekends through weekends tend to eat more, increasing the risk of overweight gain.
In the elderly, frequent vomiting can be a sign of a major problem, such as Alzheimer's disease.
"If older adults report taking very long, prolonged sleepy days during the day, it may be an alarm for clinicians," Leng said.
Proven ways to treat heart disease risk include diet rich in fruits, vegetables and heart healthy oils, no smoking, weight and blood pressure maintenance to healthy levels and frequent exercise.
Meanwhile, the American Academy of Sleep Medicine recommends that most adults attend at least seven shuteye hours a night for various health benefits.
A good bedtime pattern can help, according to sleep specialists who recommend these tips:
- Get up at the same time every day, even on weekends or on holidays.
- Keep the room in your bedroom a comfortable, cool temperature.
- Limit exposure to bright light in the evening and avoid caffeine and alcohol at bedtime.
- Turn off electronic devices at least 30 minutes before bedtime.
- Exercise regularly and maintain a healthy diet.
