Research: 6 to 7 hours of night sleep may be more beneficial for heart health


Research by a group of scientists has revealed that 6 to 7 hours of night sleep may be more beneficial for heart health.

A study presented at the scientific session of the American College of Cardiology found that individuals who slept 6-7 hours a night had the lowest risk of having a heart attack or stroke compared with those who slept less or more.

Analyzing the information of 14,79 middle-aged people who participated in the National Health and Nutrition Examination Survey conducted in the USA between 2005 and 2010, the researchers divided the participants into three categories according to the duration of their night sleep.

Later, the researchers, who examined the participants’ risk of heart disease related to atherosclerosis, determined a significant link between sleep duration and heart health as a result of the study.

Stating that sleep is generally overlooked when factors that trigger heart disease are taken into account, Henry Ford Hospital doctor Kartik Gupta, leader of the research team, noted that participants who slept less than 6 hours or more than 7 hours had a higher risk of death from heart disease-related causes.

Gupta also highlighted that not only the amount of sleep is important, but also the quality and depth of sleep.

The researchers also pointed out that individuals are in control of their sleep patterns, such as dietary habits and addictive substance use, compared to unchangeable conditions that directly affect heart disease, such as age and genetic characteristics.
