A study of over 400,000 Britons revealed that people who sleep regularly and follow a healthy nighttime routine are less likely to have heart failure than those who struggle to sleep.
The discovery explains other factors such as age, genetics and the presence of conditions such as hypertension, diabetes and obesity.
Academics from Tulane University in New Orleans took the data from the British biobank and provided anonymous participants with a “sleep score” based on the data provided.
This was compared with their heart health history over a ten-year period and the data revealed a trend between the two.
The “sleep score” depends on 5 behaviors: sleep duration, insomnia and snoring, waking up early or staying up late at night, and whether daytime sleepiness occurs.
The findings add to the emerging evidence that sleep problems may play a role in the development of heart failure.
Professor Lu Qi, from Tulane University, said: “The healthy sleep score we established was based on recording these five sleep behaviors. The results highlight the importance of improving overall sleep patterns to help prevent heart failure “.

Data analysis and questionnaires were used to examine the relationship between healthy sleep patterns and heart failure.
The researchers analyzed data from 408,802 people between the ages of 37 and 73 between 2006 and 2010.
Over a 10-year period, they recorded 5,221 cases of heart failure. Touch screen questionnaires were also used to calculate sleep grade, quality and patterns.
The researchers found that people who had a better sleep pattern overall were 42 percent less likely to develop heart failure. Those who did not report daytime sleepiness were 34% less likely to have heart failure.
It has been found that people who wake up early are 8% less likely to have heart failure, and people who sleep 7 to 8 hours a night are 12% less likely.
The researchers also found that the absence of frequent insomnia was also associated with a 17% reduced risk of heart failure.
Heart failure affects more than 26 million people worldwide and the number is expected to increase among the elderly.
Getting a good night’s sleep has been linked to a number of mental and physical health benefits, including heart health and a strong immune system.
The results are published in the journal Circulation.
