Is sleep the most amazing thing

medicine Healthy sleep lowers the risk of heart failure

Sleep is the best medicine. Not only all grandmothers and the vernacular know this, researchers also regularly use their results to prove the healing properties of sleep. As US researchers have now found, adults with healthy sleeping habits have a 42 percent lower risk of heart failure than adults with unhealthy sleeping habits. According to the study, seven to eight hours of sleep per day as well as sleep without snoring and sleep problems are considered healthy. The results of the study were published in the American Heart Association's journal "Circulation".

Heart failure affects 26 million people worldwide

Heart failure - or heart failure - affects more than 26 million people worldwide. Because the heart is too weak, it can no longer pump enough blood into the body. This leads to long-term damage up to cardiac death. Heart failure, like strokes and heart attacks, is one of the cardiovascular diseases that are the number 1 cause of death in Germany. According to the Federal Statistical Office, over 345,000 people died in 2018. That was more than every third death.

Researchers looked at sleep quality

For their study, the researchers at Tulane University in New Orleans analyzed data from just under 410,000 people between the ages of 37 and 73 years. The data from the British biobank were collected between 2006 and 2019. Over 5,200 subjects had heart failure. The scientists examined both sleep quality and general sleep patterns. To determine sleep quality, they measured sleep duration, insomnia, snoring, and other sleep-related characteristics, such as whether a participant was an early bird or a night owl and whether they were sleepy during the day.

The healthy sleep score we created was based on the assessment of these sleep behaviors. Our results underscore that good sleep habits can prevent heart failure.

Who sleeps more than nine hours a day?

The absence of insomnia significantly lowers the risk

The scientists also found other connections in the respective sleep quality categories. Regardless of when you get up and how long you sleep, the mere absence of sleep disorders leads to a 17 percent lower risk of developing heart failure. Conversely, sleep for seven to eight hours a day is enough to minimize the risk of heart failure by twelve percent.

Risk lower with early risers

The researchers found the most astonishing details in the early risers: Even if they do not sleep long and have trouble sleeping, getting up early alone can reduce the risk of heart failure by eight percent. According to the scientists, the limits of the study lie in factors influencing heart failure that may not have been measured or have been adapted to the results. On the other hand, however, there is the large sample size and the study design.
