Everyone knows him: right now, when the desired sleep just doesn't want to come.
Although most cannot go to bed early the next day to regenerate, about one in three people suffer from chronic insomnia.
A large-scale Chinese study with just under half a million participants published in the journal Neurology. It has now been shown that these people are at greater risk of having a heart attack or stroke.
Insomnia makes you sick
Those who do not get enough sleep increase the risk of cardiovascular disease.
The researchers came to this conclusion after studying 480,000 people with an average age of 51 over a decade. Participants were asked regularly if they had symptoms of insomnia last week.
This includes problems falling asleep, waking up too early or too early and difficulty concentrating the next day. These were compared with data on heart attacks and strokes; During the study, 130,032 patients experienced one of these life-threatening events.

Can early detection save lives?
Bad news for those who sleep poorly: If you show all three symptoms of insomnia, the risk of serious cardiovascular disease increases by 18%.
For those who wake up too early and cannot fall asleep again, the rate was still around seven percent.
According to study author Dr. Liming Li of Peking University, is intensifying the connection in younger adults. However, there are also opportunities for early detection, Li said: "If we treat those who suffer from sleep problems with behavioral therapy, we can prevent heart attacks and strokes later in life."
A disadvantage of the Chinese study: Although it shows a link between insomnia and cardiovascular disease, cause and effect, however, have not yet been explored.
In one, however, the researchers agree: Healthy and adequate sleep is vital to all of us.
