The heart muscle retains its strength longer in those who sleep well at night and do not want to sleep during the day.
People who maintain healthy sleep patterns are less likely to develop heart failure than those who sleep poorly. This is shown by a new study published in Circulation.
Heart failure is a condition in which the heart muscle cannot pump blood effectively. It develops gradually over many years. Among its main causes are coronary heart disease and hypertension.
At least 26 million people worldwide suffer from heart failure, and this figure is constantly growing. There is evidence that various sleep disorders may contribute to the development of heart failure. However, how this pathology is related to various indicators of healthy sleep was previously unknown.
The authors of the new study, in their previous scientific work, developed a scale of healthy sleep patterns. According to it, the healthiest pattern is the following combination: early chronotype (“nightingales”), sleep 7-8 hours a day, no insomnia, no snoring and rare daytime sleepiness.
In the new study, the authors calculated how four of the five components of a healthy sleep pattern affect the risk of heart failure. They found, that the risk of this pathology is lower:
- by 8% in early birds compared to night owls;
- by 17% in people without insomnia compared to those who often experience insomnia;
- by 34% in people who do not experience daytime sleepiness compared to those who are often drowsy.

People with the highest scores on the healthy sleep scale developed heart failure 42% less often than people with the lowest scores.
Good healthy sleep: what is it ?
Sleep is a process to which we devote almost a third of our lives. During sleep, the body recovers, and the brain packages the information received during the day. If you don't get enough sleep, you can get sick, quickly and severely.

Scientists have concluded that healthy sleep patterns are associated with a low risk of developing heart failure, regardless of known risk factors. Healthy sleep can be an important part of preventing heart weakness.
To conduct this research, scientists used data from the British Biobank. They analyzed information about the sleep patterns and health of more than 400 thousand people.
