The study warned that those who like to take naps may later face heart disease. Sun reported.

Regular sleep has been linked to high blood pressurewhich contributes to strokes and heart attacks.

And strokes are also more common in daytime people.

Researchers at Xiangya Hospital Central South University examined 360,000 people in the UK aged 40 to 69.

Between 2006 and 2019, participants provided information about their sleep habits, among other lifestyle factors.

Each was followed for an average of 11 years.

Participants were divided into groups based on the nature of their sleep: never/rarely, sometimes, or usually.

The key finding was that people who “usually” sleep had a 12% higher risk of developing high blood pressure than those who never slept.

They had a 24% higher risk of stroke.

The pattern of sleep and daytime sleep of most people remained unchanged throughout the study.

But some people have changed — and those who saw their daytime sleep increase from one category to another had a 40 percent higher risk of being diagnosed with high blood pressure.

A high percentage of people who fell into the “normal” daytime nap pattern were men, people with lower levels of education and income, cigarette smokers, and daily drinkers.

They were also typical night owls, suffering from insomnia or snoring (which could be a symptom of sleep apnea).

Co-author of the study, Dr. E. Wang, said that “taking a nap in itself is not harmful.”

However, it could be a sign that someone is not sleeping well at night, which itself is associated with poor health.

“These results are particularly interesting as millions of people can enjoy regular or even daily sleep,” Dr. Wang said.

Bad sleep from time to time – and subsequent sleep – will not kill you.

However, evidence suggests that chronically poor sleepers are more likely to develop diseases such as type 2 diabetes and heart disease.

Research also shows that they are more likely to see an early grave.

Dr. Michael A. Grandner, a sleep expert and associate professor of psychiatry at the University of Arizona at Tucson, said daytime naps are “not enough” to offset the harms of sleep deprivation.

“This study echoes other findings, which generally show that longer naps seem to reflect an increased risk of heart health and other issues,” added Dr. Grandner, who was not involved in the study.

Limitations of the study are that daytime naps are self-reported and results cannot be generalized as only middle-aged Europeans were included in the study.
