Taking a nap of more than 30 minutes can be harmful.

Napping is a habit associated with the Spanish traditionbut which extends to many other countries and cultures. The debate about its convenience or not for health comes from afar and there are opinions in both directions.

Now add one new scientific evidence. A large study conducted by Chinese researchers, using data from over half a million participantsand that warns of the possible cardiovascular health risks.

if you take a nap you will have the highest blood pressure

The research has analyzed the data from a usual source, the macro-study of the british health servicewhere information is collected from people between 40 and 69 years old UK residents.

People who nap have a 24% higher risk of having a stroke

The most outstanding results of the study are:

  • People who nap have a 12% more risk arrest high pressure.
  • They also have a 24% more risk suffering a stroke or cerebral infarction.
  • Study Participants under 60 years they had a higher risk high voltage (twenty%) than those older than this age (10%), both compared to those who do not take a nap.
  • As long as you have a most assiduous habit of nappingincreases the risk of blood pressure rising.

The study, carried out by professors from the South Central University in the city of Xiangya and has been featured in the Hypertension magazine of the American Heart Association

don’t take a long nap

The conclusion should not be that it is napping that increases the risk of stroke and hypertension“, says the Dr. Carlos Egea, President of the Spanish Federation of Sleep Medicine Societies.

There is evidence that frequent naps of more than 30 minutes They are associated with some diseases, including cardiovascular diseases. Nevertheless, “those naps are most likely a reflection of a insufficient night sleep or poor quality”, points out Dr. Egea.

Long naps were previously associated with increased risk of disease, but those of less than 30 minutes were not

In fact, the Chinese study finds that there is a demographic bias in your data. Most of the respondents who take a nap are mens, with a low economic and educational level. There is also a higher proportion of smokers, consumers of alcohol and with insomnia and snoring problems than among those who do not take a nap.

It is quite possible that the increased risk is because of what happens at nightand that the effect of naps is not enough to counteract it”, concludes Dr. Egea.

Does napping affect sleep at night?

Therefore, the study has important limitations They have to be considered before creating a lack feeling that napping is not healthy. To begin with, the researchers make no distinction in the kind of napas the duration Of the same. So we do not know how this factor can influence.

In any case, what this study could establish is that “excessive naps should serve as warning sign of insufficient night’s sleep”, adds Dr. Egea, speaking to the Science Media Centre.

The study excluded from the investigation to those people who had other pathologies that could mean a higher risk: people with diabetesprevious high blood pressure problems, cholesterol or with insomnia. However, it may not be enough.

With the information available, it is not clear if the higher frequency of stroke and high blood pressure among the napping participants could be because they had more sleep apnea”, points out the Milagros Merino, president of the Spanish Sleep Society.

how long should the nap last

Napping can be a way to help people who haven’t been able to get a good night’s rest. balance nighttime sleep deprivation.

there is even another studiowith data opposite to the one in question, and that indicate the cardiovascular benefit of taking a short nap.

take a short nap of less than 20-30 minutes is restorativeas opposed to long naps”, insists Dr. Merino. In any case “Nap paper should be individualized for each patient to assess its impact on nighttime sleep”.
