Study: Interrupted sleep is associated with an increased risk of death in women from heart disease

A study showed a strong link between interrupted sleep and an increased risk of death, especially for women. The study, published in the European Heart Journal, monitored 8001 men and women and found that women who suffer from unconscious wakefulness have an increased risk of dying from cardiovascular disease, which is twice what is observed. In the general female population.

The link was not clear in men, and it appeared that their risk of dying of cardiovascular disease due to interrupted sleep increased by just over a quarter compared to the risks in the general male population.

Unconscious wakefulness is a normal part of sleep that occurs spontaneously and plays a role in the body's ability to respond to danger. Triggers can include noise, breathing difficulties, pain, shocks, temperature, light, and limb movements.

Dominic Linz, assistant professor in the department of cardiology at the University of Maastricht Medical Center in the Netherlands, noted that a common cause of unconscious awakening is sleep apnea.

The newspaper added that sleep apnea is a sleep disorder, where the patient's breathing stops repeatedly and starts during sleep, this causes people to wake up a little as the body changes its position to reopen the airways.

Professor Linz said, "People usually feel exhausted and tired in the morning because their sleep is interrupted but they will not be aware of individual awakening, yet it was not yet known whether there was also a link between the burden of arousal" a combination of the number of states of awakening and the length of time they last. " And the risk of death.

The study was conducted by a team led by Matthias Baumert, Associate Professor from the School of Electrical and Electronic Engineering at the University of Adelaide in Australia, and Professor Linz from the University of Maastricht Medical Center in the Netherlands.

The newspaper pointed out that the data were examined from the sleep monitoring devices that men and women wear overnight in one of three studies by researchers.

Participants were followed over a period of several years, ranging from 6 to 11 years on average, and data were recorded accordingly.

After adjusting the results to take other influencing factors into account, the researchers found that the burden of arousal for women was less than that of men.

In fact, it appears that women who had problems waking up, which accounted for more than 6.5% of their nightly sleep, had a higher risk of dying from cardiovascular disease compared to women who had fewer waking problems.

Overall, the risk of dying from any cause was 21% among women in the general population, however, this percentage increased to 31.5% among women in the two studies.

On the other hand, men who suffer from waking problems that make up more than 8.5% of their night's sleep are at risk of death by 13.4%, and 33.7% respectively from cardiovascular disease or any cause.

In the general population, men of the same ages had a risk factor of 9.6% and 28%, respectively.

Professor Linz said: "It is not clear why there is a difference between men and women, but there are some possible explanations. The stimuli that cause arousal or the body's response to stimulation may differ in women compared to men, and this may explain the relatively high risk of cardiovascular death in women."

The professor added that the waking burden could be affected by age, body mass index and severity of sleep apnea.

He explained, "While age cannot be changed, body mass index (BMI) and sleep apnea can be modified and may represent an interesting goal to reduce the burden of influencing factors.

The European Society of Cardiology also notes that the results are only able to show an association between the burden of waking up during sleep and an increased risk of death.
