It's news that would keep you up at night, if you weren't already struggling to get to sleep.
People who have trouble getting shut eye are significantly more likely to have a heart attack or stroke, a study has warned.
Scientists looked at nearly 500,000 people and found the risk of the killer events spiked for insomniacs by nearly a fifth.
The findings, by researchers in China, add to a wealth of studies which have linked insomnia to poor health outcomes.
People who have trouble sleeping at night are significantly more likely to suffer a heart attack or stroke, scientists say
It is widely believed that the condition, suffered by an estimated one in three adults, changes bodily functions.
Sleep is vital as a restorative time, making the person feel energised and refreshed, experts say.
It also gives the immune system and the cardiovascular system a much-needed rest, and at the same time allows other organs to be restored.
Experts believe lack of sleep raises blood pressure and alters the metabolism - both known risk factors of cardiovascular disease.
Chinese researchers followed 480,000 people for a decade. Participants had an average age of 51 and had no history of heart problems.
Relax before going to bed. Have a warm bath, listen to music or practise meditation or yoga. Use bath salts, or throw in Epsom salts and baking soda - one cup of each. These will relax you and also help remove toxins from your body.
Don't eat heavy meals close to bedtime. The energy your body will generate to digest the meal will keep you awake.
