In a large American study, it was established that people who are sleeping seven hours at night are also 3.7 years younger than their biological age.
At the same time, those who are sleeping six or eight hours have a 4.5 year older heart than the “calendar” should be!
In addition, the biggest risk is in people who sleep five or fewer hours.
Their heart is five years older from the biological age.
Longer periods of low sleep have negative effects on multiple body systems.
That also includes cardiovascular system.
Sleeping is connected with your heart
The analysis also shows a significant link between sleep duration and heart disease risk.
Sleeping has a connection with:
– High cholesterol
– And also obesity
That was the conclusion of Dr. Quanhe Yang, Senior Scientist of the American Center for Disease Control and Prevention in Atlanta.
The definition of anticipated age of human cardiovascular system based on all risk factors is named “Heart Age”.
This definition was introduced in 2008.
“The difference between the estimated age of the heart and the biological years of a person is termed “heart rate overrun”.
In addition, when the difference is bigger, the risk of developing heart disease is greater.
For example, if a 40-year-old man, depending on his risk factors, has an estimated 44-year-old heart rate, his heart rate exceeds four years.
In addition, it means that his heart is four years older than it should be.
The concept of” heart years “serves us to simplify the risk for heart disease.
Therefore, we are more easily complicated by it,” explains Jang.
Seven hours of sleeping is an ideal time
Jang and colleagues analyzed the data of 12,755 persons between the ages of 30 and 74 in the period 2007-2014.
At the same time, they divided them into five groups by the duration of their sleep.
About 13 percent of the respondents slept for five hours or less.
24 percent slept for six hours.
31 percent slept for seven hours.
26 percent slept for eight hours.
And 5 percent slept for nine or more hours.
They made “Heart Age” calculations and they also took into account all other risk factors.
The sleeping that is too short or too long also has a connection with increased heart risk.
The smaller risks have those who are sleeping seven hours – said Dr. Quanhe Yang for “Reuters”.
