In the News
Insomnia may raise the risk of a heart attack or stroke by almost a fifth, research suggests.
The study involved more than 487,000 people with an average age of 51 who had no history of stroke or heart disease.
Participants were asked if they had any of three symptoms of insomnia at least three days per week: trouble falling asleep or staying asleep; waking up too early in the morning; or trouble staying focused during the day due to poor sleep.
They were then followed for an average of about 10 years during which there were 130,032 cases of stroke, heart attack and other similar diseases.
People who had all three symptoms of insomnia were 18 per cent more likely to develop the diseases than people who did not have any symptoms, according to the findings published by the journal Neurology.
