Poor sleep may increase risk of heart attack, stroke
London, Apr 2: Researchers have found that suffering from insomnia may put people at increased risk of heart attack and stroke.
A large-scale study of over 160,000 people found a clear association between sleep problems and the debilitating effects of a heart attack or stroke.
Difficulty getting off to sleep, staying asleep, and waking up not feeling refreshed increased the risks by 27 per cent, 11 per cent, and 18 per cent respectively.
Women are at a slightly higher risk than men as they are more prone to insomnia because of differences in genetics, sex hormones and their reaction to stress.
Sleep is vital as a restorative time and plays a significant role in healing and repairing the heart and blood vessels. It also gives the immune system and the cardiovascular system a rest and allows other organs to be restored.
The study looked at the connection between insomnia symptoms and incidents or death from cardiovascular disease, including acute myocardial infarction, coronary heart disease and heart failure, or stroke, or a combination of issues.
Researchers examined 15 studies with a total of 160,867 participants.
The study found women with insomnia symptoms had a slightly higher risk of cardiovascular and stroke events than men, especially for non-restorative sleep.
