Maintaining the Right Amount of Sleep can Lower the Risk of Heart Disease

What is your daily sleep duration? While some people sleep for only 3 to 4 hours per night, others manage to get 6 to 7 hours of sleep. Studies reveal that the latter group demonstrates better cardiovascular health indicators.

Detroit, MI (ADH News) – It is imperative not to underestimate the importance of sleep. According to a study by Henry Ford Hospital in the United States, sleeping too long or too short may increase the risk of heart disease. Researchers have found that sleep can play a role in cardiovascular risk in the same way as diet, smoking, or exercise. It is recommended that a suitable sleep time is 6 to 7 hours.

Researcher Kartik Gupta and his team analyzed the data of participants in the National Health and Nutrition Examination Survey from 2005 to 2010, a total of 14,079 people. The average age of these participants was 46, and 10% of them had a history of heart disease and related complications.

“Sleep is often overlooked, but it may play a role in cardiovascular disease, which may be one of the most cost-effective ways to reduce the risk of cardiovascular disease.” Dr. Kartik Gupta said.

Participants were divided into three groups for observation. They were followed for an average of 7.5 years to observe their deaths from heart disease, heart failure, or stroke. The researchers compared the participants’ Atherosclerotic cardiovascular disease (ASCVD) and C-reactive protein (CRP) from the participants’ sleep and related data.

“Participants with insufficient sleep or too long sleep have higher CRP indicators, which increased inflammation measured by CRP may cause. Those who show insufficient sleep or too much sleep have a higher risk of inflammation.” Dr. Kartik Gupta explained.

Researchers also found that people who sleep 6 to 7 hours a night have the lowest chance of dying from a heart attack or stroke. However, people who sleep 6 to 7 hours a night have the same ASCVD as those who sleep more than 7 hours, indicating that ASCVD may not fully reflect the risk of heart disease.

Since everyone needs to pay different labors at work, and the sleeping environment and quality are also different, will these lead to differences in research results? The research team emphasized that the current study suggests that sleep for 6 to 7 hours can reduce the risk of heart disease, but sleep includes conditions such as depth and quality, so the results need to be further verified.
