Good sleep helps in lowering risk of heart failure

New York – A new study shows those who have healthy sleep pattern have 42 per cent lower risk of heart failure regardless of other risk factors compared to those who have poor sleep patterns.

Researchers say in a study published in the journal Circulation that healthy sleep patterns are getting up early in the morning, sleeping seven to eight hours a day and no excessive daytime sleepiness.

“Our findings highlight the importance of improving the overall sleep patterns to help prevent heart failure,” said study author Lu Qi from the Tulane University in the US.

This observational study examined the relationship between healthy sleep patterns and heart failure and included data on 408,802 UK Biobank participants, ages 37 to 73 at the time of recruitment (2006-2010).

Incidence of heart failure was collected until April 1, 2019. Researchers recorded 5,221 cases of heart failure during a median follow-up of 10 years.

Researchers analysed sleep quality as well as overall sleep patterns.

The measures of sleep quality included sleep duration, insomnia and snoring and other sleep-related features, such as whether the participant was an early bird or night owl and if they had any daytime sleepiness.

“The healthy sleep score we created was based on the scoring of these five sleep behaviors,” Qi said.

Sleep behaviors were collected through touchscreen questionnaires.

Sleep duration was defined into three groups: short, or less than seven hours a day; recommended, or even to eight hours a day; and prolonged, or 9 hours or more a day.

The findings showed that participants with the healthiest sleep pattern had a 42 per cent reduction in the risk of heart failure compared to people with an unhealthy sleep pattern.
